ITEM NO. 2.1 AGENDA REPORT Meeting Date: May 4, 2010 Budgeted: Yes To: Public Information-Technology Cost Estimate: N/A Committee Funding Source: All Water Funds From: Ken Vecchiarelli, General Manager Presented By: Steve Conklin, Engineering Dept: Engineering Manager Reviewed by Legal: N/A Prepared By: Derek Nguyen, Water Quality CEQA Compliance: N/A Engineer Subject: 2010 Public Health Goals Report SUMMARY: A draft copy of the District-prepared Public Health Goals Report for 2010 is attached. California Law mandates that the District prepare a Public Health Goals (PHG) report every three years if any water quality measurements exceed any PHG levels or Maximum Contaminant Goal (MCLG) levels. The report provides information to the public about the occurrence of constituents in the public water supply, the health risks associated with the contaminant, and the approximate cost to totally eliminate any trace contaminants regardless of how minimal the risk might be. PHG levels and MCLG levels are not enforceable standards and no action to meet them is required. STAFF RECOMMENDATION: That the Committee recommend the Board of Directors approve the 2010 Public Health Goals Report; authorize staff to notice the public of the availability of the report for review and comment; and schedule a public hearing on June 24, 2010 to receive and respond to public comments. DISCUSSION: California Code of Regulations' Health and Safety Code Section 116470 (b) mandates that the District, as an agency with more than 10,000 service connections, prepare a Public Health Goals Report by July 1, 1998 and thereafter, every three years if any water quality measurements exceed any Public Health Goals or Maximum Contaminant Level Goals. The law requires the Public Health Goals Report to address constituents in the water that are above Public Health Goal (PHG) levels established by the California Office of Environmental Health Hazard Assessment (OEHHA). For constituents where OEHHA has not set a PHG level, then the USEPA MCLGs apply. PHGs and MCLGs are not enforceable standards and no action to meet them is required. Only six (6) water constituents (total coliform, lead, copper, arsenic, uranium and gross alpha) were detected that exceeded their PHGs and MCLGs. It should be noted that none of the water constituents detected exceeded the enforceable primary drinking water standards. The law also requires the governing Board to officially accept the Public Health Goals report, notify the public of its availability for review and hold a public hearing to respond to and/or accept public comments. PRIOR RELEVANT BOARD ACTION(S): On August 23, 2007, the Board of Directors approved and accepted the final draft of the 2007 Public Health Goals Report.

Board of Directors William R. Mills, President Michael J. Beverage John W. Summerfield Vice President Board Member Phil Hawkins Ric P. Collett Board Member Board Member Ken Vecchiarelli, P.E. General Manager Introduction The limits established in California's regulatory drinking water standards protect the public from harmful substances, but no water supply is ever completely free of contaminants. Some, such as arsenic and uranium, can occur naturally. Others, such as fuels, industrial solvents, pesticides and metals, may enter water supplies from chemical spills and leaking tanks and pipelines, or they may be a legacy of agricultural and waste- disposal practices that pre-dated modern environmental laws. It is natural for people to want their drinking water to be completely free of all contaminants. However, preventing or removing all contamination often is not economically or technologically feasible. State health authorities are responsible for determining the levels of contaminants that, based on current laws and recommendations, can remain in water supplies without compromising human health. Public Health Goals and Drinking Water Standards To help keep drinking water safe, the California Legislature passed the Calderon-Sher Safe Drinking Water Act of 1996. This law requires the California Department of Public Health (CDPH) to regularly test drinking water supplies and set standards for contaminants in water. The Act also requires the Office of Environmental Health Hazard Assessment (OEHHA) to develop Public Health Goals (PHGs) for contaminants in California's publicly supplied drinking water. Public water utilities with more than 10,000 service connections are required by the provisions of the California Health and Safety Code Section 116470 (b) to prepare a Public Health Goals report by July 1, 1998 and every three years thereafter if any water quality measurements exceed any of the Public Health Goal levels or Maximum Contaminant Level Goal levels. What is a Public Health Goal? A PHG is the level of a chemical contaminant in drinking water that does not pose a significant risk to health. PHGs are not regulatory standards; however, state law requires CDPH to set drinking water standards for chemical contaminant as close to the corresponding PHG as is economically and technically feasible. In some cases, it may not be feasible for CDPH to set the drinking water standard for a contaminant at the same level as the PHG. The technology to treat the chemicals may not be available, or the cost of treatment may be very high. CDPH must consider these factors when developing a drinking water standard. PHGs are non-enforceable goals established by the California-Environmental Protection Agency's (Cal-EPA) Office of Environmental Health Hazard Assessment. The law requires that where OEHHA has not -memo-%. - .MO i~ - -w r it f ..T 00 i adopted a PHG for a constituent, the water suppliers are to use the Maximum Contaminant Level Goals (MCLGs) adopted by the United States Environmental Protection Agency (USEPA). Only constituents which have primary drinking water standard and for which either a PHG or MCLG has been set are to be addressed. Appendix 1 is a list of California's PHGs and Appendix 2 is a list of the Federal MCLGs. Included in the appendices are the test results for YLWD for the years 2007-2009. If a constituent was detected in the District's water supply from year the years 2007 to 2009 at a level exceeding an applicable PHG or MCLG, this report provides the information required by law. Also included in this report is the numerical public health risk associated with the PHG and/or MCLG, the category or type of risk to health that could be associated with constituent, the best treatment technology available that could be used to reduce the constituent level, and an estimate of the cost to install that treatment, if appropriate and feasible. The purpose of the law is to give water system customers access to information on levels of contaminants even below the enforceable mandatory drinking water standard known as Maximum Contaminant Levels (MCLs). In addition, the law intends to provide an idea of the cost to totally eliminate any trace of the contaminant from drinking water regardless of how minimal the risk might be. The required report is unique to California. How does OEHHA Establish a Public Health Goal? The process for establishing a PHG for a chemical contaminant in drinking water is very rigorous. OEHHA scientists first compile all relevant scientific information available, which includes studies of the chemical's effect on laboratory animals and studies of humans, who have been exposed to the chemical. The scientists use data from these studies to perform a health risk assessment, in which they determine the levels of the contaminant in drinking water that could be associated with various adverse health effects. In performing the health risk assessment, OEHHA considers the following factors: • Certain groups of people, such as pregnant women, young children, the elderly or persons with pre-existing illnesses, who may be especially susceptible to the chemical's adverse effects. The PHG must consider health effects on individuals in these groups. • Accumulated effects of exposure to the chemical from other sources, such as food, air and soil; as well as and other forms of drinking water, such as showering. MW • The chemical's potential to interfere with bodily functions in a way that increases the risk of chronic health problems, such as liver damage. • Possible synergistic effects from the combined exposure to the chemical in question with other chemicals, which may further increase health risks. When calculating a PHG, OEHHA uses all the information it has PHGs Set at Levels That compiled to identify the level of the chemical in drinking water Protect Human Health that would not cause significant adverse health effects in people who drink that water every day for 70 years. OEHHA For carcinogens, OEHHA assumes that an adult will drink two liters of water per day and establishes the PHG at the a child will drink one liter per day. OEHHA must also consider "one-in-one-million" risk any evidence of immediate and severe health effects when level. At that level, not more setting the PHG. than one person in a population of one million Water Quality Data Considered people drinking 2 liters of All of the water quality data collected by the District in the water daily for 70 years years 2007, 2008, and 2009 for purposes of determining would be expected to compliance with drinking water standards were considered. develop cancer as a result of This data is also summarized in the District's Annual Water exposure to that chemical. Quality Reports, also known as Consumer Confidence Reports, For chemicals that cause which are mailed out to all of our customers in July of each health effects other than year. cancer, OEHHA sets the PHG at a level that is not expected Guidelines Followed to cause any toxic effects, The Association of California Water Agencies (ACWA) formed a including birth defects and workgroup which prepared guidelines for water utilities to use chronic illness. in preparing these newly required reports. The ACWA guidelines were used in preparation of this report. No guidance was available from state regulatory agencies. Best Available Treatment Technologies and Cost Estimates Both the USEPA and CDPH adopted what are known as Best Available Technologies (BATS). BATS are the best known methods of reducing contaminant levels to below MCL. Costs can be estimated for such technologies. Since many PHGs and all MCI-Gs are set much lower than the MCL, it is not always possible or feasible to determine what treatment is needed to further reduce a constituent downward to or near the PHG or MCLG, many of which are set at zero. Estimating costs to reduce a constituent to zero is difficult, if not impossible, to verify by analytical means that the level has been lowered Ilk, to zero. Additionally, in some cases, installing treatment to try and further reduce very low levels of one constituent may have adverse effects on other aspects of water quality. Constituents Detected That Exceed a PHG or MCLG The following is a discussion of the constituents that were detected in the District's drinking water sources and water distributions system above the PHG, or if no PHG, above the MCLG. T tai Coimfon Bacteria Total coliform (TC) bacteria are indicator organisms that indicate a potential microbial water quality problem that requires confirmation follow-up sampling, testing, and investigation. When the District receives a positive TC result from the contract laboratory, a repeat sample set is immediately taken for a retest. In addition, the disinfection procedures are reviewed and the sample collection site and the adjacent section of the water distribution system are analyzed. The MCLG for total coliform (TC) bacteria is zero percent (0%) of samples with presence of coliform per month. The MCL for TC is not to exceed five percent (5%) of positive or coliform-presence samples per month. During the years 2007, 2008, 2009, combined staff and an independent certified testing laboratory collected and analyzed from the District's water distribution system an average of 160 TC samples each month, for a total of 5778 samples over the last three years. From these 5778 samples, there were 51 which tested positive for TC. This equates to a 3-year average monthly percentage of TC positive samples is 0.89%, which exceeds the MCLG of zero percent (0%). Factors that can produce positive TC test besides degraded water quality include, but are not limited to, the weather and environmental conditions when samples are taken, and the human factor associated with the collection methods, handling, and test procedures. Because total coliform is only a surrogate indicator of the potential presence of pathogens, it is not possible to state a specific numerical public health risk. While USEPA normally sets MCLGs "at a level where no known or anticipated adverse effects on persons would occur", they indicate that they cannot do so with coliforms. w Yam. The California Department of Public Health has determined that the presence of TC bacteria is a possible health concern. TCs are common in the environment and are generally not harmful themselves. State of California Health and Safety Code Section 64470(a) states: "The presence of these bacteria in drinking water, however, generally is a result of a problem with water treatment or the pipes which distribute the water, and indicates that the water may be contaminated with organisms that can cause disease. Disease symptoms may include diarrhea, cramps, nausea, and possibly jaundice, and any associated headaches and fatigue. These symptoms, however are not just associated with disease causing organisms in drinking water, but may also be caused by a number of factors other than your drinking water." The addition of disinfectants to the drinking water is the best available technology to eliminate or reduce the presence of TC. The District disinfects with and monitors chlorine levels at our sources and water system to assure that the water served is microbiologically safe. The chlorine residual levels are carefully controlled to provide the best health protection without causing the water to have undesirable taste and odor or increasing the disinfection by-product level. This careful balance of treatment processes is essential to continue supplying our customers with safe drinking water. In addition, the District also has an effective cross-connection program, maintains positive pipeline pressures, and, conducts a regular flushing program for water distribution system dead-end mains. The District has already taken necessary steps associated with best management practices and the best available technology for the prevention and control of TC in our water distribution system. e!elySince we are applying a disinfectant and conducting a thorough effort to eliminate and prevent the presence of TC, it is not prudent to initiate additional treatment as proper disinfection and frequent flushing programs have proven to be effective methods in destroying possible TC contamination, therefore no estimate of cost has been included. Lead Lead occurs in drinking water as a result of leaching or dissolving from household plumbing and plumbing fixtures containing lead. The District's well water and import water sources do not contain lead. Lead found inside homes is a chemical reaction of the District's water with household plumbing fixtures which contain lead. % There is no Maximum Contaminant Level for lead. United States Environmental Protection Agency and the California Department of Public Health Notification Level for lead is 0.015 milligrams per liter. The notification level for lead is measured at the 90th percentile lead level of all samples taken from inside the customer's household taps every three years. The California Office of Environmental Health Hazard Assessment established a Public Health Goal of 0.002 milligrams per liter. The District's 90th percentile of all samples taken from inside the customers' houses in 2009 sampling for lead is 0.006 milligrams per liter, which is well below the above-described Notification Level. The Office of Environmental Health Hazard Assessment and the Department of Health Services has determined the following health risk for lead: "Based on human data, the category of health risk for lead is neurotoxicity (decreased learning ability). Neurotoxicity is lead's capability of destroying or adversely affecting the nervous system, or interfering with the nerve signal transmission. Infants and children who drink water containing lead in excess of the Environmental Protection Agency and California Department of Health Services Notification Level of 0.015 mg/L could experience delays in their physical or mental development and show slight deficits in attention span and learning abilities. Adults who drink water containing lead in excess of the Environmental Protection Agency California Department of Public Health Notification Level of 0.015 mg/L over many years could develop kidney problems, high blood pressure, and cancer." The Office of Environmental Health Hazard Assessment has a numerical cancer risk of 3 x 10-7 for the 0.002 mg/L PHG, and a cancer risk of 2 x 10-6 for the California Department of Public Health Notification Level of 0.015 mg/L. NOTE. Cancer Risk is defined as the theoretical 70-year lifetime excess cancer risk at a statistical confidence limit. Actual cancer risk may be lower or zero. Cancer risk is stated in terms of excess cancer cases per million (or fewer) population. For examples, 3 x 10-7 means 3 excess cancer cases per 10,000,000 people, 2 x 10-6 means 2 excess cancer cases per 1,000,000 people. (From the above, that means that 3 and 2 more people will get cancer than if the population had not been exposed to the chemical.) L e a re- 3 ' P. o ae rer - - In general, optimizing corrosion control is the best available technology to reduce the level of lead in drinking water. This is achieved through evaluations of the effectiveness of adjusting alkalinity, pH, and calcium hardness, and the addition of phosphate or silica- based corrosion inhibitors, or a combination of all. Optimizing corrosion control also includes an intensive process of collection and analyses of water quality data to determine the effectiveness of corrosion control. Our water system is in full compliance with the Federal and State Lead and Copper Rule. Based on our 2009 extensive sampling, it was determined according to State regulatory requirements that we meet the Notification Levels for lead and copper, and therefore deemed by the State Department of Public Health to have optimized corrosion control. Since the District meets the "optimized corrosion control" requirements, it is not prudent to initiate additional corrosion control treatment as it involves the addition of other chemicals, which could lead to additional water quality issues. Therefore, no estimate of cost has been included. Copper 4011,b- The District's well water and import water sources do not contain copper. Copper found inside homes is a chemical reaction of the District's water with household plumbing fixtures containing copper and brass. There is no Maximum Contaminant Level for copper. United States Environmental Protection Agency and the California Department of Public Health Notification Level for copper is 1.3 milligrams per liter. The notification level for copper is measured at the 90th percentile of all samples taken from plumbing fixtures inside the customer's home. Lead and Copper tests are conducted once every 3 years as required by CDPH. The California Office of Environmental Health Hazard Assessment has established a Public Health Goal of 0.17 milligrams per liter. The District's 90th percentile of all samples taken from inside the customers' houses in 2009 sampling for copper is 0.21 milligrams per liter. -INNNMWL s _ ` ~ ~ \ f i~' ~ f - = a - =~~r~:•i~ ~ - _ "fir - The Office of Environmental Health Hazard Assessment and the Department of Health Services have determined the following risk for copper: "Based on human data, the health risk category for copper is acute toxicity. Acute toxicity is adverse health effects that develop after a short-term exposure to copper. Short term exposure to high levels of copper can temporarily cause problems in the gastrointestinal system." The Office of Environmental Health Hazard Assessment has determined that, in the case of copper, there is no numerical public health risk associated with the Public Health Goal. Numerical public health risks are not calculated for chemicals considered non- cancer causing. 1W Both the U.S. Environmental Protection Agency and California Department of Public Health adopt what are known as Best Available Technologies which are the best-known methods of reducing contaminant levels to the Maximum Contaminant Level. Since many of the Public Health Goals and Maximum Contaminant Level Goals are set much lower than the Maximum Contaminant Level, it is not always possible or feasible to determine what treatment is needed to further reduce a substance to or near the Public Health Goal or Maximum Contaminant Level Goal. Similar to lead, optimizing corrosion control is the best available technology to reduce the level of copper in drinking water. This is achieved through effectively adjusting and maintaining alkalinity, pH, and calcium hardness, and the addition of phosphate or silica- based corrosion inhibitors, or a combination of all. Optimizing corrosion control also includes an intensive process of collection and analyses of water quality data to determine the effectiveness of corrosion control. Arsenic is a naturally occurring element in the earth's crust and is very widely distributed in the environment. All humans are exposed to small quantities of arsenic (inorganic and organic) largely from food and to a lesser degree from drinking water and air. Some edible seafood may contain higher concentrations of arsenic which is predominantly in less acutely toxic organic forms. L YLWD's Well No. 15 slightly exceeds the 10 parts per billion (ppb) arsenic primary drinking water standard, the MCL. Currently, Well No. 15's 3-year average arsenic level is approximately 10.58 ppb. Other District wells have an average 2.90 ppb arsenic level. Whenever in operation, staff blends Well 15 water with other District wells in compliance with State Health approved blending plan. Blended well water served to our customer has an arsenic level of about 4.0 ppb, which is well below the current not-to- exceed level of 10 ppb arsenic MCL. The California Office of Environmental Health Hazard Assessment has established a Public Health Goal of 0.004 micrograms per liter or parts per billion (ppb). The Office of Environmental Health Hazard Assessment has determined arsenic as a carcinogen. Ink The Office of Environmental Health Hazard Assessment has a numerical cancer risk of 1 x 10-6 for the 0.004 ppb PHG, and 1 in four hundred for the EPA Maximum Contaminant Level of 10 ppb. Note that, as previously described, cancer risk is stated in terms of excess cancer per million (or fewer) population. The value of 1 x 10-6 means 1 excess cancer case per 1,000,000 people. (1 excess case means 1 person will get cancer than if the population had not been exposed to the chemical.) Approximate Treatment e-t Activated alumina, ion exchange, reverse osmosis, lime softening, coagulation/filtration are the water treatment technologies available for achieving compliance with the MCL for arsenic. It would cost the District approximately $12 million dollars in capital cost excluding annual operation and maintenance costs to reduce the arsenic levels of all its well water to the PHG level of 0.004 ppb.* * based on HDR-Southern California Arsenic Workshop, 2002 adjusted for 2010 dollars with estimated 3.5% annual inflation, using granular ferric hydroxide with removal limit up to <0.002 ppb. -10moft, Uranium Naturally occurring uranium is found in groundwater supplies as a result of leaching from uranium-bearing sandstone, shale, and other rock formations. Uranium may also be present in surface water, carried through runoff from areas with mining operations. The Public Health Goal for uranium is 0.43 pico-Curies per liter (pCi/L), and the Maximum Contaminant Level (MCL) is 20 pCi/L. The District's average uranium level is 8.01 pCi/L. The levels detected were below MCL at all times. The Office of Environmental Health Hazard Assessment has determined uranium as a carcinogen. The Office of Environmental Health Hazard Assessment has a numerical cancer risk of 1 x 10-6 for the 0.43 pCi/L PHG, and a cancer risk of 5 x 10-5 for the California Department of Health Maximum Contaminant Level of 20 pCi/L. As previously described, 1 x 10-6 means 1 excess cancer case per 1,000,000 people; 5 x 10-5 means 5 excess cancer cases per 100,000 people. (land 5 excess cases mean 1 and 5 persons respectively will get cancer than if the population had not been exposed to the chemical.)

Using reverse osmosis, it would cost the District about $45 million dollars in annualized capital, and operation and maintenance cost to achieve the PHG level**. based on CH2M Hill Study, for a 1.0 mgd plant operated at 40% design capacity, October 1991 adjusted for 2010 dollars with estimated 3.5% annual inflation. Gross Alpha Radionuclides such as alpha in water supplies are from erosion of natural deposits. The term radionuclide refers to naturally occurring elemental radium, radon, uranium, and thorium with unstable atomic nucleus that spontaneously decays producing ionizing radiation. Gross alpha is defined as the sum total of these radionuclides. Exposure to ionizing radiation in concentrations exceeding the maximum contaminant level may have carcinogenic (cancer causing), mutagenic (causing mutation of cells) or teratogenic (causing abnormalities in offspring) effects. The EPA's Maximum Contaminant Level Goal (MCLG) for gross alpha particle is 0 and the California Maximum Contaminant Level (MCL) is 15 pCi/L. The District's average level of gross alpha is 8.33 pCi/L. The levels detected were below MCL at all times. Health risk category based on experimental animal testing data evaluated in the U.S. EPA MCLG document and California MCL has determined gross alpha particle as a carcinogen. IqW ,41111111h.- The USEPA's MCLG for Gross Alpha is zero (0) and a cancer risk of 1 x 10-3 for the California Department of Public Health Maximum Contaminant Level of 15 pCi/L. NOTE. Cancer Risk = theoretical 70-year lifetime excess cancer risk at a statistical confidence limit. Actual cancer risk may be lower or zero. Cancer risk is stated in terms of excess cancer per million (or fewer) population. The value of 1 x 10-3 means 1 excess cancer case per 1,000 people. (1 excess case means 1 person will get cancer than if the population had not been exposed to the chemical.) jy to Remove or Reduce the Concentration of Gross Alpha Particles and Approximate Treatment Cost Similar to uranium, reverse osmosis, lime softening, and coagulation/filtration are the water treatment technologies available for achieving compliance with the MCL for uranium. Removal and reduction could be achieved concurrently with uranium. Nil- Conclusion: ■ Drinking water provided by the Yorba Linda Water District meets 100% of all enforceable State of California, Department of Public Health, and United States Environmental Protection Agency primary drinking water standards. The District also meets 94% of all the California Public Health Goals and 92% of the Federal Maximum Contaminant Level Goals. Public Health Goal levels are not enforceable water quality standards, and no action to meet them is mandated. For total coliform bacteria, the staff does not recommend further action. The District has already taken all steps associated with the best available technology and multi- barrier approach for control and occurrence prevention of total coliform bacteria including an effective cross-connection program, maintenance and monitoring of proper disinfectant levels, regular water quality monitoring of wells and reservoirs, source water protection, and maintenance of positive pipeline pressures throughout the distribution system. For lead and copper, the District already has optimized Yorba Linda Water District corrosion control, and the District's water has been meets 100% of all found to be non-corrosive. Staff does not recommend enforceable drinking water undertaking additional corrosion control efforts. It is standards from the not recommended for two reasons: 1) the United California Department of States Environmental Protection Agency and California Public Health and the Department of Public Health classified the District's United State system as having optimized corrosion control, and 2) Environmental Protection adding chemicals for more corrosion control will cause Agency. other water quality problems. These could reduce the effectiveness of the current disinfection process which could increase the presence of total coliforms. In addition, contributing factors such as type and age of plumbing and plumbing fixtures, point-of-use and point-of-entry water treatment devices, and electro- chemical-induced pipe corrosion could change the water chemistry in customers' taps, thus increasing water lead and copper content. For arsenic, the District's State Health Department approved blending plan and performance requirements are being met to keep the level of arsenic below the enforceable standard. Providing additional treatment for 100% removal to meet the PHG would be cost-prohibitive. 4 MW NO M~ For uranium and gross alpha particle, current methods of removal and disposal technologies do not provide complete reduction to meet the level of the public health goals at this time. In the future, if available removal technology can be achieved, the District will explore and conduct the necessary studies and related costs to implement. In summary, the drinking water served by the Yorba Linda Water District meets all State of California, Department of Public Health and USEPA drinking water standards set to protect public health. To further reduce the levels of constituents identified in this report that are already significantly below the health-based Maximum Contaminant Levels established to provide safe drinking water, additional costly treatment processes would be required. The effectiveness of the treatment processes to provide any significant reduction in constituent levels at already low values is uncertain. The health protection benefits of these further hypothetical reductions are not all clear and may not be quantifiable. Furthermore, the funds that would be required for the additional treatment, approximately $57 million, might provide greater public health protection benefits to the District's customers if spent on improving other water system operation, surveillance, and monitoring programs. -low APPENDICES Appendix 1 State of California Public Health Goals (PHGs) Comparison with YLWD Water Quality (Units are in milligrams per liter (mg/L), unless otherwise noted) Constituent MCL State PHG YLWD Test Imported Water or MCLG Results Results Organic Chemicals - 22 CCR § 64444 Alachlor 0.002 0.004 ND ND Atrazine 0.001 0.00015 ND ND Bentazon 0.018 0.2 ND ND Benzene 0.001 0.00015 ND ND Benzo (a) pyrene 0.0002 0.000004 ND ND Carbofuran 0.018 0.0017 ND ND Carbon Tetrachloride 0.0005 0.0001 ND ND Chlordane 0.0001 0.00003 ND ND Chloro-ethylene (Vinyl Chloride) 0.0005 0.00005 ND ND Cis-1,2-Dichloroethylene 0.006 0.1 ND ND 2,4-Dichlorophenoxyacetic acid (2,4-D) 0.07 0.07 ND ND Dalapon 0.2 0.79 ND ND Dibromochloropropane (DBCP) 0.0002 0.000007 ND ND 1,2-Dichlorobenzene (ortho) 0.6 0.6 ND ND 1,4-Dichlorobenzene (Para) 0.005 0.006 ND ND 1,1-Dichloroethane (1,1-DCA) 0.005 0.003 ND ND 1,2-Dichloroethane (1,2-DCA) 0.0005 0.0004 ND ND 1,1-Dichloroethene (1,1-DCE) 0.006 0.01 ND ND Dichloromethane 0.005 0.004 ND ND 1,2-Dichloropropane 0.005 0.0005 ND ND 1,3-Dichloropropene 0.0005 0.0002 ND ND Di (2-ethylhexyl) adipate 0.4 0.2 ND ND Di (2-ethylhexyl) pthalate (DEHP) 0.004 0.012 ND ND Dinoseb 0.007 0.014 ND ND Diquat 0.02 0.015 ND ND Endothall 0.1 0.58 ND ND Endrin 0.002 0.0018 ND ND Ethylbenzene 0.3 0.3 ND ND Ethylbenzene Dibromide (EDB) 0.00005 0.00001 ND ND I Glyphosate 0.7 1 ND ND Heptachlor 0.00001 0.000008 ND ND Heptachlor Epoxide 0.00001 0.000006 ND ND Hexachlorobenzene 0.001 0.00003 ND ND Hexachlorocyclopentadiene 0.05 0.05 ND ND Lindane 0.0002 0.000032 ND ND Methoxychlor 0.03 0.03 ND ND Methyl Tertiary Butyl Ether (MTBE) 0.013 0.013 ND ND Monochlorobenzene 0.07 0.2 ND ND Oxa myl 0.05 0.05 ND ND Pentachlorophenol (PCP) 0.001 0.0004 ND ND Picloram 0.5 0.5 ND3 ND Silvex (2,4,5-TP) 0.05 0.025 ND ND Simazine 0.004 0.004 ND ND 1,1,2,2-Tetrachloroethane 0.001 0.0001 ND ND Tetrachloroethylene (PCE) 0.005 0.0006 ND ND Thiobencarb 0.07 0.07 ND ND Toluene 0.15 0.15 ND ND Toxaphene 0.003 0.00003 ND ND Trans-1,2-Dichloroethylene 0.01 0.06 V ND ND 1,2,4-Trichlorobenzene 0.005 0.005 ND ND 1,1,1-Trichloroethane (1,1,1-TCA) 0.2 1.0 ND ND 1,1,2-Trichloroethane (1,1,2-TCA) 0.005 0.0003 ND ND Trichloroethylene (TCE) 0.005 0.0008 ND ND Trichlorofluoromethane (Freon 11) 0.15 0.7 ND ND Trichlorotrifluoroethane (Freon 113) 1.2 4 ND ND Xylenes (sum of isomers) 1.75 1.8 ND ND Inorganic Chemicals - 22 CCR § 64431 Aluminum 1 0.60 0.004 ND Antimony 0.006 0.02 ND ND I Barium 1 2 ND ND Beryllium 0.004 0.0001 ND ND Cadmium 0.005 0.00004 ND ND Cyanide 0.15 0.15 ND ND Fluoride 1.4 to 2.4 1 0.4 0.15 Mercury 0.002 0.0012 ND ND Nickel 0.1 0.012 ND ND Nitrate as Nitrate 45 45 14 2 Nitrite as Nitrogen 1 1 ND ND Thallium 0.002 0.0001 ND ND Radiological Chemicals - 22 CCR § 64441 and 64443 Abbreviations: 1.

This report is also known as the "Consumer Confidence Report" which covers water quality testing and analysis from January to December of the previous calendar year. State and Federal laws require that this annual water quality report be sent to every customer by July 1 to insure that customers are informed of the quality of their drinking water. Attached is a draft copy of the District-prepared 2010 Water Quality Report. STAFF RECOMMENDATION: That the Committee recommend the Board of Directors approve the 2010 Water Quality Report and authorize staff to print and distribute a copy of this report to every District customer. DISCUSSION: State and Federal laws require that the District prepare an annual Water Quality Report and distribute copies to its customers by July 1 of each year. This annual report covers water quality monitoring, testing and analysis conducted from January to December of the previous calendar year. The purpose of this report is to inform consumers of the water they are receiving. In 2009, the District conducted over 23,000 analyses to ensure that its water met all State and Federal drinking water regulations. In some cases, the District goes beyond what is required by State and Federal laws, by providing additional monitoring for contaminants of concern. Staff is pleased to report that the District has never violated any drinking water regulation from both the State and Federal standards. PRIOR RELEVANT BOARD ACTION(S): In July 2009, the Board of Directors approved and authorized distribution of the District's 2009 Water Quality Report to its customers.

This year's report also known as the "Consumer Confidence Report," covers water quality testing from January to December 2009. The Yorba Linda Water District's annual Water Quality Report is prepared in compliance with x the regulations called for in the 1996 reauthorization of the Safe Drinking Water Act (SDWA). The reauthorization charged the United States Environmental Protection Agency (USEPA) with updating and strengthening the tap water regulatory program. Drought tolerant plants in front of District's Admin Building USEPA and the California Department of Public Health (CDPH) are the agencies responsible for establishing water quality standards. To ensure that your tap water is safe to drink, USEPA and CDPH prescribe regulations that limit the amount of certain contaminants in water provided by water systems. The State and Federal governments require that this annual water quality report be sent to every customer to insure that you are informed of the quality of your water. The District is committed to safeguarding its water supply and, as in years past, the water delivered to your home meets the standards required by the state and federal: regulatory agencies. r K In 2009, we conducted over 23,000 analyses to ensure that your water is clean and safe to drink. We are proud to report that our water system= , has never violated any water quality standard from both the State and _ Federal drinking water regulations. In some cases, the District goes rrr beyond what is required by providing additional monitoring for Well d 19 w d the Durfet Wmheuse in the Backjw ed contaminants that may have health risks. We encourage you to read this report and to contact us with any questions you may have. "MM • mission is to provide reliable, high quality water and sewer services in an environmentally responsible manner at the • economical • to • customers. ff What You Need to Know about Your Water, and How it May Affect You Wafter, fster~R mrfor °flr-e Yorba Linda Water District is an independent special district that provides water and sewer service to most of the City of Yorba Linda and to portions of Anaheim, Brea, Placentia and unincorporated Orange County. For more information about the District or your water service, please call t. Management Analyst Cindy Botts, at 714.701.3024 or Water Quality Engineer Derek Nguyen at 714.701.3115. The Yorba Linda Water District Board of Directors' regularly scheduled meetings are held on the second and fourth Thursday of each month at 8:30 a.m. in the District boardroom located at 1717 E. Miraloma Avenue, Placentia, California 92870. MA The District's water supply is a blend of groundwater from our own wells and water imported from Northern California and the Colorado River by the Metropolitan Water District of Southern California (MWD). The source water for our wells is a natural aquifer that is replenished with water from the Santa Ana River, local rainfall and imported water. Managed by the Orange County Water District, the groundwater basin is approximately 350 square miles in area and lies beneath most z of northern and central Orange County. The Yorba Linda Water District and more than 20 cities and retail water districts pump from the groundwater basin to provide - w a- water to homes and businesses. Your water source depends on where you live or work within the boundaries of our community. To find out which water source is provided to your home or business, please visit the Water Quality Division of the District's website: http://www.vlwd.com/quality/index-guality.htmi The District obtains approximately half of its water supplies from wells located within the District. The District's groundwater sources include: Well No. 1, Well No. 5, Well No. 7, Well No. 10, Well No. 12, Well No. 18 and Well No. 19, which are located within Placentia city limits; and Well No. 11 and Well No. 15, which are located within Anaheim city limits. The District obtains the remainder of the water from local wholesaler Municipal; Water District of Orange County (MWDOC). MWDOC obtains water from regional supplier Metropolitan Water District of Southern California (MWD). MWD obtains water from northern California via the California Aqueduct, and from the Colorado River via the Colorado River Aqueduct. MWD owns and operates the Robert B. ' Diemer water treatment plant located just north of western Yorba Linda where the water is treated to meet drinking water standards. J r~ ,f ► 161 The sources of drinking water (both public tap water and bottled water) include rivers, lakes, streams, ponds, reservoirs, springs, and groundwater. As water travels over the surface of the land or through the ground, it dissolves naturally occurring minerals and, in some cases, radioactive material. Water also picks up substances resulting from the presence of animals or from human activity. Drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some contaminants. The presence of contaminants does not necessarily indicate that water poses a health risk. To learn • about the potential health effects of contaminants listed in this report, call the EPA's Safe Drinking Water • 1-800-426-4791 or by accessing the EPA's internet web site at www.epa.gov/safewater Cc; Vii, 46 Microbial contaminants, such as viruses and bacteria, which may come from sewage treatment plants, septic systems, agricultural livestock operations, and wildlife. Cryptosporidium is a microscopic organism that when ingested can cause diarrhea, fever, and other gastrointestinal maladies. The organism comes from animal and/or human waste and may be found in surface (imported) water. A standard treatment process that includes sedimentation, filtration, and disinfection can eliminate cryptosporidium contamination. 4, Pesticides and herbicides that may come from a variety of sources such as agriculture, urban storm water runoff and residential uses. 46 Inorganic contaminants, such as salts and metals that can be naturally occurring or result from urban storm water runoff, industrial or domestic wastewater discharges, oil and gas production, mining or farming. Organic chemical contaminants, including synthetic and volatile organic k chemicals that are by-products of industrial processes and petroleum ti production, and can also come from gas stations, urban storm water r~_.: w = runoff, agricultural application and septic systems. .r Radioactive contaminants that can be naturally occurring or be the result of oil and gas production and mining activities. w ' . Radon is a radioactive gas that you cannot see, taste, or smell. It is found throughout the world. Radon can move through the ground and into homes through cracks and holes in the foundation. Radon can build up to high levels in all types of homes. Radon can also get into indoor air when released from tap water from showering, washing dishes, and other household activities. Compared to radon entering the homes through soil, radon entering the home through tap water will, in most cases, be a minor source of radon in indoor air. Radon is a known human carcinogen. Breathing air containing radon can lead to lung cancer. Drinking water containing radon may also cause increased risk of stomach cancer. If you are concerned about radon, test the air in your home. Testing is inexpensive and easy. You may want to consider modification to your home if the level of radon in your air is 4 picoCuries per liter of air (pCi/L) or higher. There are simple ways to fix a radon problem that are not too costly. For additional information, you can call the EPA's Radon Hotline (800-SOS-Radon). The EPA proposed MCL for radon is 300 pCi/L. The proposal will provide flexibility to the states on how to limit exposure to radon by allowing states to focus efforts on the greatest radon risks-those in indoor air-while also reducing the risks from radon in drinking water. The states' option for radon compliance is as follows: First Option: States can choose to develop enhanced state programs to address the health risks from radon in indoor air. These programs are known as Multimedia Mitigation (MMM) Programs. Individual water systems reduce radon levels in drinking water to 4,000 pCi/L or lower. EPA is encouraging states to adopt this option because it is the most cost effective way to achieve the greatest radon risk reduction. Second Option: If a state chooses not to develop an MMM program, individual water systems in that state would be required to either reduce radon in their system's drinking water to 300 pCi/L or develop individual local MMM programs and reduce levels in drinking water to 4,000 pCi/L. The District does not add fluoride to its groundwater supplies. Naturally occurring fluoride is present in the aquifer, but not at a level that provides dental health benefits. In 1995, the California Legislature passed a bill mandating that all large water agencies fluoridate their supplies, but only if the state or "somebody" provided the agencies with the funds to do so. To date, the state has not come up with the funds to implement fluoridation. MWD commenced fluoridation of the drinking water it supplies to Southern California in • • • • November of 2007. The District purchases approximately half of its water from MWD. ;t~,a glance Because of MWD's decision and the District's dual Rack[!Co1.1n e _ sources of water (groundwater and import), YLWD is faced with a situation where some of its customers will receive water fluoridated by MWD, some will receive non-fluoridated water, and some will receive a blend of fluoridated and non-fluoridated water. If you wish to know the approximate level of fluoride in your tap water, or specific water service area, please call Derek Nguyen, Water Quality Engineer, at 714.701.3115. Additional information about the fluoridation of drinking water can be found through the following sources: ➢ U.S, Centers for Disease Control and Prevention, 1-888-CDC-2306 www.cdc.gov/Oralhealth/factsheet/fl-background.html y_ .aN ~ur~ d ;c ~ '4 ➢ American Dental Association www.ada.org/public/topics/fluoride/fluor-links.htmi ➢ American Water Works Association www.awwa.org Some individuals may be more vulnerable to the effects of possible contaminants in drinking water than the general population. Persons who are undergoing chemotherapy, persons who have undergone organ transplants, some elderly persons, infants, persons infected with HIV/AIDS, or persons with other immune system disorders can be particularly at risk. These persons should seek advice from their health care providers about drinking water. The USEPA/Center for Disease Control guidelines on appropriate means to lessen the risks of infection by cryptosporidium or other microbial contaminants are available from the Safe Drinking Water Hotline (1-800-426-4791). Drinking water standards established by the U.S. EPA and CDPH set limits for substances that may affect consumer health or aesthetic qualities of drinking water. The chart in this report shows the following types of water quality standards. ➢ Maximum Contaminant Level (MCL): The highest level of a contaminant that is allowed in drinking water. Primary MCLs are set as close to the PHGs (or MCLGs) as is economically and technologically feasible. ➢ Maximum Residual Disinfectant Level (MRDL): The level of a disinfectant added for water treatment that may not be exceeded at the consumer's tap. ➢ Secondary MCLs are set to protect the odor, taste, and appearance of drinking water. ➢ Primary Drinking Water Standard: MCLs for contaminants that affect health along with their monitoring and reporting requirements and water treatment requirements. ➢ Regulatory Action Level (AL): The concentration of a contaminant, which, if exceeded, triggers treatment or other requirements that a water system must follow. The District samples and tests it water sources throughout the year. Contaminants are measured in: ➢ Parts per million (ppm) or milligrams per liter (mg/1) ➢ Parts per billion (ppb) or micrograms per liter (µg/1) ➢ Parts per trillion (ppt) or nanograms per liter (ng/1) Parts per million: Parts per billion: Parts per trillion: 1 second in 12 days 1 second in 32 years 10 drops in a Rose Bowl-sized pool 1 penny in $10,000 1 penny in $10 million 1-second in 32,000 years 1 inch in 16 miles 1 inch in 16,000 miles 1 inch in 16 million miles E[4 i P ' ,ra y _ grz* What is a dater Ouality G 1 In addition to mandatory water quality standards, U.S. EPA and CDPH have set voluntary water quality goals for some contaminants. Water quality goals are often set at such low levels that they are not achievable in practice and are not directly measurable. Nevertheless, these goals provide useful guidance and directions for water management practices. The chart in this report includes three types of water quality goals: ➢ Maximum Contaminant Level Goal (MCLG): The level of a contaminant in drinking water below which there is no known or expected risk to health. MCLGs are set by U.S. EPA. ➢ Maximum Residual Disinfectant Level Goal (MRDLG): The level of a disinfectant added for water treatment below which there is no known or expected risk to health. MRDLGs are set by U.S. EPA. ➢ Public Health Goals (PHG): The level of a contaminant in drinking water below which there is no known or expected risk to health. PHGs are set by the California Environmental Protection Agency - Office of Environmental Health Hazard Assessment. In December 2002, Metropolitan Water District of Southern California (MWD) completed a source water assessment of its Colorado River and State Water Project supplies. Colorado River supplies are considered to be most vulnerable to contamination by recreational uses, urban/storm water runoff, industrial runoff, increasing urbanization in e the watershed and wastewater contamination. State Water Project supplies are a a considered to be most vulnerable to urban/storm water runoff, and wildlife, agriculture, a recreation and wastewater contamination. A copy of the assessment can be obtained by contacting MWD by phone at 213.217.6850 u Groundwater Assessme- e The District completed an assessment of its Wells No. 1, 5, 7, 10, and 12 in January 1999. The wells are considered most vulnerable to contaminants produced by the following activities: gas stations; dry cleaners; metal plating/finishing/fabricating plants; plastic/synthetic producers; underground injection of commercial/industrial discharges; underground storage tanks; agricultural drainage; fertilization, pesticide and herbicide application; automobile-body and repair shops; and chemical/petroleum processing/storage. l Vulnerability assessments of potential sources of r contamination for Wells 11 and 15 were completed in April 2003. These groundwater sources are considered most fL• 6 4 vulnerable to the following activities not associated with A detected contaminants: chemical/petroleum ' processing/storage; metal plating/finishing/fabricating; and F - plastics/synthetics production. '+04r;- A vulnerability assessment of potential sources of contamination for Well 19 and Well 18 were completed in r May 2004 and September 2005, respectively. The 11 groundwater sources are considered most vulnerable to the - following activities not associated with detected contaminants: gas stations; dry cleaners; metal plating/finishing/fabricating plants; plastic/synthetic producers; underground injection of commercial/industrial discharges; underground storage tanks; agricultural drainage; 7> 7 fertilization, pesticide and herbicide application; automobile-body and repair shops; sewer collection systems; food processing, and chemical/petroleum processing/storage. A copy of the complete assessment is available at Department Public of Health District Office at 605 West Santa Ana Blvd., Building 28, Room 325, Santa Ana, CA 92701. You may contact CDPH Sanitary Engineer Minliang Shih at 714.547.0430. Measurements In order to ensure that tap water is safe to drink, EPA and CDPH prescribe regulations that limit the amount of certain contaminants in water provided by public water systems. u The tables below list all the drinking water contaminants that the District detected during the 2009 calendar year. The presence of these contaminants in the water does not necessarily indicate that the water poses a health risk. Unless otherwise noted, the data presented in this table is from testing done for the period January 1 through December 31, 2009. The CDPH requires monitoring for certain contaminants less often than every year because the concentrations of these contaminants are not expected to vary significantly from year to year. Thus, some of the data, though representative of current water quality, is more than one year old. The District contracts with state certified, independent laboratories to perform most of the District's water quality testing.

For more about the award program, visit www.cacities.orq/helenputnam . The City of Mountain View, located in the heart of Silicon Valley, receives the majority of its water from the Hetch Hetchy Valley, more than 250 miles away. Ensuring the availability of reliable and safe water for its residents in the event of an emergency, such as a major fire or potential disruption to the water system, became a priority for the city in 2002 as it worked to meet the ongoing challenges of emergency preparedness. In addition to improving water supply reliability, the city also wanted to provide additional emergency water storage. Finding an appropriate facility to house the reservoir was a challenge, however, because Mountain View lacked undeveloped land. At the same time that the city was considering its options, the Mountain View Whisman School District (MVWSD) had initiated steps to begin refurbishing its athletic fields at the Graham Middle School site but did not have the funding to construct or maintain new athletic fields. Convergence of Community Needs Recognizing a potential partnership, in 2003 the city negotiated with the MVWSD for joint use of Graham Middle School's sports fields. In exchange for the right to construct a buried reservoir beneath the playing fields, the city agreed to construct and maintain new athletic fields on top of the reservoir as a shared-use facility for students during the day and residents after school hours. The Graham Reservoir and Sports Complex project integrated efficient planning and engineering to construct an 8 million-gallon reservoir on the school site and an adjacent pump station, topped by a turf-covered recreational deck. The project also incorporated a groundwater well to provide another source of water. For operational and cost efficiency, the city separated the project into three bid packages and took advantage of the school's summer break to expedite the project and reduce the impact on the school during construction, which began in 2004 and was completed in 2006. Mountain View Mayor Tom Means is enthusiastic about the project. He explains, "The Graham Reservoir and Sports Complex embodies many of the core principles of good government, including community engagement, partnerships and innovative land use to meet the needs of our community." Project Provides Multiple Benefits Community uses of the facility range from daily school athletic activities, summer youth programs and soccer leagues to individual runners and walkers who use the track for daily exercise. Students and residents enjoy the immediate benefits of an all-weather track and athletic fields, and the entire community is assured that the city has an adequate water supply in the event of an emergency. "Besides the millions of gallons of water this reservoir cleverly stores for the citizens of Mountain View, it's a joy to see how much the students of Graham Middle School happily embrace this world-class sports complex," says MVWSD Superintendent Maurice Ghysels. "This project's positive impact on students and staff has been tremendous. Kids go outside more, play more and are in better shape because of our collaboration with the City of Mountain View." "This project meets emergency water needs into the next century and provides a recreation facility of the highest quality. It demonstrates how a city and a school district can work together to get maximum use out of increasingly scarce land," adds Cathy Lazarus, public works director for the City of Mountain View. http://www.westcrncity.com/corc/pagctools.php?pagcld-I 1295&ur1%2FWestern-City%2F... 5/5/2010 Western City I Mountain View Combines Reservoir and Sports Complex Page 2 of 2 In addition to much positive feedback from residents, the project has received numerous honors and awards for its engineering and environmental efficiencies. The Graham Reservoir and Sports Complex offers an excellent example of innovative land use and partnerships in the construction and maintenance of public works infrastructure.

Print Article: Doggie play lot before Yorba Linda council tonight Page 1 of 1 . ME ORANGE COUNTY STER Doggie play lot before Yorba Linda council tonight By JESSICA TERRELL 2010-05-04 14:23:28 YORBA LINDA - Whether Yorba Linda needs a doggie play lot is expected to be addressed at tonight's City Council meeting. The Parks and Recreation Commission has recommended that the council approve the building of a test lot at Brush Canyon Park in the east end of Yorba Linda. The city had been looking at underutilized areas of city parks for a small, low-maintenance play lot, said Lauren Cochran, management assistant for the city. The design could be something like the dog lots in Dana Point, which cost that city an average of $10,000 to build, Cochran said. There is currently no area in the city where dogs can run off-leash. The council is also expected to hear a presentation by Yorba Linda Water District General Manager Ken Vecchiarelli on the benefits of transferring over the city-owned portion of the sewage system to the YLWD. The council had directed staff in February to begin transfer discussions with the water district. The sewage system in Yorba Linda is divided between the city and the Yorba Linda Water District. The city owns and maintains the eastern portion of the system, starting roughly at San Antonio Road. The city charges $19.47 a year per parcel on the system. The Yorba Linda Water District currently charges $66 a year per single-family home hooked into its sewage line. Because of rising costs and increasingly demanding state sewage mandates, the city is not charging enough to pay for the cost of maintaining the aging system, according to staff reports. A proposal to increase rates to $7.19 a month or $86.26 a year failed to pass the City Council last August. "The City Council seems to have a lot of consternation about what to do with this public asset," Vecchiarelli said. "They are having a lot of trouble raising their maintenance charge to what it costs to provide the service. We are here to take that headache away from them." The meeting will be at 6:30 p.m. in the Council Chambers, 4845 Casa Loma Ave. Contact the writer: 714-704-3719 Iterrell(a~ocregister.com © Copyright 2010 Freedom Communications. All Rights Reserved.
