March 1999 Agency �=CEPA Preparing Your Drinking Water Consumer Confidence Report Guidance for water suppliers Notice This document provides guidance to water suppliers on EPA's current interpretation of the Consumer Confidence Report Rule. The guidance is designed to implement national policy on these issues. The document does not, however, substitute for EPA's regulations; nor is it a regulation itself. Thus, it cannot impose legally -binding requirements on EPA, states, or water suppliers, and may not apply to a particular situation based upon its circumstances. EPA and state decisionmakers retain the discretion to adopt approaches on a case-by-case basis that differ from this guidance where appropriate. EPA may change this guidance in the future.

This guide explains all of the requirements for report content, format, and distribution that the U.S. EPA established in the Consumer Confidence Report Rule, published in the FEDERAL REGISTER on August 19, 1998. The rationale for consumer confidence reports (CCRs) is that consumers have the right to know what is in their drinking water and where that water comes from. The reports will help consumers to make informed choices that affect the health of themselves and their fami- lies. They also will encourage consumers to consider the challenges of delivering safe drink- ing water. Educated consumers are more likely to help protect their drinking water sources and to understand the true costs of safe drinking water. Water suppliers, states, and EPA are all working to educate consumers about the sources and quality of their drinking water, and to increase their involvement in decisions about it. EPA is revising its public notification re- quirements to speed up notification of serious health threats and simplify notification of other violations. Systems and states are including citizens in decisions regarding use of the drink- ing water state revolving fund and in planning source water assessment programs. Consumers who are familiar with the basic drinking water information in CCRs will be able to participate more effectively in these processes. I. What is a consumer confidence report? In 1996, Congress amended the Safe Drink- ing Water Act. It added a provision requiring that all community water systems deliver to their customers a brief annual water quality report. CCRs summarize information that your water system already collects to comply with regulations. You will not need to engage in any new monitoring just for the CCR. The CCR includes information on your source water, the levels of any detected contami- nants, and compliance with drinking water rules, plus some educational material. Most reports will fit on a few sheets of paper. A report that contains too much information or is full of technical jargon can discourage consum- ers from learning about their drinking water. II. Who must prepare a consumer confidence report? Every community water system that has at least 15 service connections serving year round residents must prepare and distribute a report. These systems typically include cities, towns, homeowners associations, and trailer parks. A water wholesaler that sells water to an- other water system must provide the retailer with monitoring data and other information that will enable the retailer to produce a CCR, unless the two systems make a different con- tractual agreement. Wholesalers are not respon- 1 sible for creating the report for the retailer, nor are they responsible for providing data on contaminants that the retailer monitors (such as lead or trihalomethanes). Regardless of who produces the report, the retail system is respon- sible for ensuring that its customers receive a report containing all required content. In some cases, a retailer will contract with the wholesaler to produce the report. There are several options in this relationship. If the retailer had no new data to add, it could simply send out the wholesaler's CCR with a cover letter explaining their relationship. If the re- tailer did need to add data, it might choose to reprint the wholesaler's CCR with a new ti- tle/letterhead and extra data. Either of these is acceptable. III. When must a water system distribute its report? You must deliver your first report to con- sumers by October 19, 1999. The reports are based on calendar -year data, so your first report will include data collected between January - December 1998. In 2000 and the years following, your system must deliver its report to consumers by July 1. Wholesalers must deliver information to their buyers by April 1999 (unless there is a separate agreement), and annually thereafter. A new community water system must deliver its first report by July 1 of the year after its first full calendar year in operation, and annually thereafter. IV. What content is required in the report? This guidance describes EPA's require- ments for a CCR and suggests (using the words "we encourage," "should," and "may") - other sections or explanations that will help your customers understand the report. Your state's CCR rule may require more information, so be sure to check with your state drinking water program. basic Consumer Confidence Report requirements (please read on for details and recommended enhancements) water system information • namelphone number of contact person • information on public participation opportunities • information for non-English speaking populations, if applicable sources of water • type, name, and location of water sources • availability of source water assessment • information on significant sources of contamination, if available definitions: MCL, MCLG, others as needed detected contaminants • table summarizing data on detected regulated & unregulated contaminants • known or likely source of each detected contaminant • [for MCL violations] health effects language and explanation • information on Cryptosporidium, radon, and other contaminants, if applicable compliance with other drinking water regulations • explanation of violations, potential health effects, and steps taken to correct the violations • explanation of variance/exemption, if applicable required educational information • explanation of contaminants and their presence in drinking water • warning for vulnerable populations about Cryptosporidium • infnrmatinna) ctatpmPntc nn arcAnir nitratA anA 1a 1 if nnn veo 2 EPA encourages you to tailor the content of your CCR to local conditions. If you think that an added picture or graph would help your customers to understand your report, add it. If your customers would benefit from an explana- tion of your need for new treatment facilities, tell them. As long as any additional educational information is consistent with, and not detract- ing from, the purpose of the report, you may add it. For example, the CCR rule does not require a title for your report. However, you should give your report a title to catch the cus- tomer's attention. You may call the report a "consumer confidence report," a "water quality report," or choose another title. Customers are most interested in a clear statement of whether or not their drinking water meets all EPA and state standards. Although it is not required by the regulations, you will help your customers if you tell them whether their water met all drinking water standards. Be cautious in using the word "safe" since water that meets standards and is safe for most people might not be safe for infants, chemotherapy patients, or people with HIV/AIDS. EXAMPLE -Last year, as in years past, your tap water met all EPA and state drinking water health standards. Local Water vigilantly safeguards its water supplies and once again we are proud to report that our system has never violated a maxi- mum contaminant level or of any other water quality standard. [or, if you had a violation, begin with: Last year, we conducted more than _ tests for over 80 contaminants. We only detected of those contaminants, and found only _ at a level higher than EPA allows. As we told you at the time, our water temporarily exceeded drinking water standards. For more information, see the para- graph marked Violation on the back.] This bro- chure is a snapshot of last year's water quality. Included are details about where your water comes from, what it contains, and how it compares to EPA and state standards. We are committed to provid- ing you with information because informed custom- ers are our best allies. Item 1: Water system information Identify the name of your system, and provide the following information about it: The name and telephone number of a person at the water system who can answer ques- tions about the report. A list of known opportunities for public participation in decisions that affect drink- ing water quality (e.g., time and place of regularly -scheduled water board or city/ county council meetings). If you do not have regularly -scheduled meetings, tell customers how to get information when meetings are announced. Systems that have a large proportion of non- English speaking residents must include infor- mation in the appropriate language expressing the importance of the report or offering addi- tional information in that language. The state 3 will make the final determination of which systems need to include this information. EXAMPLE -This report contains important infor- mation about your drinking water. Translate it, or speak with someone who understands it. -Spanish—Este informe contiene informaci6n muy importante sobre su agua beber.

Traduisez-le ou parlez en avec quelqu'un qui le comprend bien. Item 2: Source(s) of water Describe your water (ground water, surface water, or a blend), and the commonly -used name(s) (if such a name exists) and locations of your water source(s). We encourage you to provide a simple map of your system's sources. Explaining your various interconnections and back-up sources may be difficult, but it is important that consumers understand that the source of their water may vary during the year. Remember to include in your table of detected contaminants monitoring data for these "extra" sources if you use water from them. If your situation is complex, you may need to work with someone from your state drinking water program to decide what information belongs in your report. If a source water assessment has been completed, tell customers where to get a copy. If you have received your source water assess- Item 3: Definitions Every CCR must include definitions of key terms that consumers will need to understand the contaminant data. You must use the defini- tions listed below. • Maximum Contaminant Level (MCL): The highest level of a contaminant that is allowed in drinking water. MCLs are set as close to the MCLGs as feasible using the best available treatment technology. • Maximum Contaminant Level Goal (MCLG): The level of a contaminant in drink- ing water below which there is no known or expected risk to health. MCLGs allow for a margin of safety. Include the following definitions only if your report contains information on a detected contaminant that is regulated by an action level 4 ment, include in the report a brief summary of your source water's susceptibility to contamina- tion based on the findings of the source water assessment. The state should develop this summary as part of the source water assessment process and provide it to you, or you may write it yourself. If you do not have information from the source water assessment, we encourage you to include any other information about potential sources of contamination that is readily avail- able to you; for example, information contained in a sanitary survey. This is your opportunity to educate your customers about the impacts that they and others have on the quality of their source water. You may want to provide pollu- tion prevention tips or information on local watershed cleanup activities. (e.g., lead) or a treatment technique (e.g., tur- bidity): • Treatment Technique: A required process intended to reduce the level of a contaminant in drinking water. • Action Level: The concentration of a contami- nant which, if exceeded, triggers treatment or other requirements which a water system must follow. Include the following definition only if your water system operated under a variance or exemption during the calendar year that the report describes: • Variances and Exemptions: State or EPA permission not to meet an MCL or a treatment technique under certain conditions. Item 4: Detected contaminants An essential part of the report is the table that shows the highest level of each detected contaminant (this is usually the value you report to the state to determine compliance) and the range of levels of that contaminant you found during the year, if compliance is based on an average of several samples. A detected contaminant is any contaminant detected at or above its minimum detection limit (MDL). (See Appendix B) If you are unsure of the MDL for a contaminant, and your lab reports a value greater than zero, include that in the report. Your state may have lower MDLs that take precedence over EPA's. Do not include in the table contaminants that are not detected or are detected below the MDL. If you sometimes distribute water from emergency or back-up sources, you generally need to include monitoring results from these sources in the ranges of detections that you report in the table, unless the source's contribution is insignificant (e.g., one day per year). The main table of detected contaminants must contain o___y data about regulated contami- nants (contaminants subject to a MCL, treat- ment technique (TT), or action level (AL)), and unregulated contaminants for which EPA or the state requires monitoring under 40 CFR 141.40 or the Information Collection Rule (ICR). See below for special instructions about Crypto- sporidium and radon. You may make several tables to separate regulated contaminants from those that do not have MCLs, such as ICR contaminants. You may want to organize your table(s) by contaminant type (e.g., microbial, inorganic) or sampling site (e.g., treatment plant, distribution system). Report any addi- tional monitoring data in another section of the CCR, separated from the regulated contaminant data. If you want to list all the contaminants which you monitored but did not detect, you must do so outside of the table of detected contaminants. If you choose to report on sec- ondary MCLS, or if your state requires this reporting, do so outside of the main table. To ensure that consumers can easily com- pare detected contaminant levels to their MCLs, your table must display the MCL for each contaminant in units that express it as a number greater than 1.0. Report the MCLG and level of the detected contaminant in the same units as the MCL. For example, atrazine is usually reported in mg/l. It is easier for customers to see that your water contains atrazine at a level 10 times lower than the MCL if you report the MCL as 3 ppb and the detected level as 0.3 ppb than if you were to report the MCL as 0.003 mg/l and the detected level as 0.0003 mg/l. In this case, you convert by multiplying the de- tected level and MCL by 1000. Appendix A shows the conversion factor for each contami- nant. When you round results to determine compliance, round before multiplying the results by the factor listed in Appendix A. 5 The CCR includes data from monitoring completed during the past calendar year. How- ever, if you have monitoring waivers, or for another reason monitor less than once per year, use your most recent data. For example, if you monitor once every three years for lindane and detect lindane in a sample, report the same detection level each of the three years until you take a new sample. If the report contains detec- tion data that is not from the calendar year indicated, the table must show the date of monitoring and the report must contain a brief statement explaining that the data presented is from the most recent monitoring done in com- pliance with regulations. EXAMPLE—The state allows us to monitor for some contaminants less than once per year because the concentrations of these contaminants do not change frequently. Some of our data, though representa- tive, are more than one year old. You do not need to report monitoring re- sults that are more than five years old. Report the results of Information Collection Rule monitoring only for five years from the date of the last sample or until the detected contami- nant becomes regulated and subject to regular monitoring, whichever comes first. The table must contain, for each detected contaminant: (1) the MCL, expressed as a number greater than 1.0 (see Appendix A). If the contami- nant is regulated by a TT, put the letters "TT" in place of the MCL. If the contami- nant is regulated by an AL, specify the applicable Action Level. (2) the MCLG, expressed in the same units as the MCL (see Appendix A). (3) the level of that contaminant expressed in the same units as the MCL and MCLG: ► if compliance is determined annually or less frequently (many inorganic and chemical contaminants), include the highest detected level at any sampling point and the range of detected levels, if applicable. ► if compliance is determined by a running annual average of all the samples taken from a sampling point (for example, chemical contami- nants), include the highest average (as reported to the state for compliance purposes) and the range of detections. (See Appendix C) ► if compliance is determined by a running annual average of all samples at all sampling points (for example, TI Hlvis), include the highest average and the range of detected levels. (See Appendix C) ► for turbidity (when reported pursuant to 40 CFR 141.13—turbidity as a MCL for systems that must install filtration but haven't), include the highest monthly average. R ► for turbidity (when reported pursuant to 40 CFR 141.71—turbidity as a TT for systems that have met criteria for avoiding filtration), in- clude the highest single measurement found in any month. You should explain the reasons for measuring turbidity. EXAMPLE—Turbidity is a measure of the cloudiness of the water. We monitor it because it is a good indicator of water quality. High turbidity can hinder the effectiveness of disinfectants. ► for turbidity (when reported pursuant to 40 CFR 141.73 —turbidity as a TT for systems that filter and use turbidity as an indicator of filtra- tion performance), include the highest single measurement and the lowest monthly percent- age of samples meeting the turbidity limits specified in 141.73 for the relevant filtration technology. (See Appendix C) Beginning with your 2003 report, report turbidity based on the revised requirements in 141.173. You should explain the reasons for measuring turbidity. EXAMPLE—Turbidity is a measure of the �1 cloudiness of the water. We monitor it because it is a good indicator of the effectiveness of our filtration system. ► for lead and/or copper, include the 90`'' percentile value from the most recent sampling (if it is a number greater than zero) and the number of sites that exceeded the action level. Do not report related parametric data. ► for total coliforms (systems that collect fewer than 40 samples per month), include the highest number of positive samples collected in any one month. D. for total coliforms (systems that collect 40 or more samples per month), include the high- est percentage of positive samples collected in any one month. for fecal coliforms and E. coli, include the number of positive samples taken that year. 110' � ► If you detect beta particles in your water at or below 50 pCi/l, you should report the detected level in pCi/l. So that consumers may have a standard against which to compare that detected level, include "50*" in the MCL column (rather than the actual MCL of 4 mrem/year) and include a footnote to the table that says "*EPA considers 50 pCi/l to be the level of concern for beta particles." If you detect beta particles above 50 pCi/l, you must determine the actual radioactive constituents present in the water to calculate the dose exposure level in mrem/ year, and must report both the detected level and MCL as mrem/year. (4) the likely source of that contaminant, to the best of your knowledge. If you have reli- able information, the report should identify a specific point source, such as "Al's chick- en houses" or the "Super -shiny Paper Mill". If you lack reliable information on the specific source of a contaminant, include one or more of the typical sources listed in Appendix B that is most applicable to your situation. (5) for any contaminant detected in violation of a MCL or a TT, or exceeding an AL, clearly highlight in the table the violation or exceedence. This indication could, for example, take the form of a different color type, a larger or bolder font, or a large star. Near, but not in, the table, include an expla- nation of the length of the violation/ exceedence, the potential adverse health effects (from Appendix A), and actions you took to address the violation/exceedence. (6) If you've detected unregulated contaminants for which state or federal rules require monitoring (for example, the ICR or 40 CFR 141.40), except Cryptosporidium, include the average of all of the year's monitoring results and the range of detec- tions. See Appendix A for a list of these contaminants. We encourage you to include more informa- tion on the potential health effects of these contaminants if the results may indicate a health concern. We consider any detection above a proposed MCL or health advisory level to indicate concern. You can call the Safe Drinking Water Hotline (800-426- 4791) for this information or find it on EPA's web site at www.epa.gov/safewater/ hfacts.html. For these contaminants, EPA recommends that the report contain an explanation of the significance of the re- sults, noting the existence of the health advisory or proposed MCL. You may wish to explain the reasons for unregulated contaminant monitoring with a statement like the following. EXAMPLE—Unregulated contaminant moni- toring helps EPA to determine where certain contaminants occur and whether it needs to regulate those contaminants. Multiple distribution systems If your system supplies water through two or more distribution systems that use different raw water sources and are not physically inter- connected, you may want to include in the table a separate column of detection data for each service area. Describe the area that each distri- bution system serves. ReDortinng on Cryptosporidium and radon If you monitored for Cryptosporidium and/or radon and did not detect them, you do not need to discuss the monitoring or the results in your report. 7 If your system has performed monitoring that indicates the presence of radon in its fin- ished water, include in the report: the results of monitoring (the analytical values reported by the lab). an explanation of the significance of the results. Tell customers if they need to be concerned by the information that the CCR provides. EXAMPLE --Radon is a radioactive gas that you can't see, taste, or smell. It is found throughout the U.S. Radon can move up through the ground and into a home through cracks and holes in the foundation. Radon can build up to high levels in all types of homes. Radon can also get into in- door air when released from tap water from show- ering, washing dishes, and other household activi- ties. Compared to radon entering the home through soil, radon entering the home through tap water will in most cases be a small 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 in your home, test the air in your home. Testing is inex- pensive and easy. Fix your home if the level of radon in your air is 4 picocuries per liter of air (pCYL) or higher. There are simple ways to fix a radon problem that aren't too costly. For addi- tional information, call your state radon program or call EPA's Radon Hotline (800 -SOS -RADON). If your system has performed monitoring that indicates the presence of Cryptosporidium either in its source water or its finished water, include the following information in your report: • a summary of the results of the monitoring. You may choose whether or not to report the actual analytical results as a part of this summary. an explanation of the significance of the results. Tell customers if they need to be concerned by the information that the CCR provides. EXAMPLE. Cryptosporidium is a microbial path- ogen found in surface water throughout the U.S. Although filtration removes cryptosporidium, the most commonly -used filtration methods cannot guarantee 100 percent removal. Our monitoring indicates the presence of these organisms in our source water andlor finished water. Current test methods do not allow us to determine if the or- ganisms are dead or if they are capable of caus- ing disease. Ingestion of cryptosporidium may cause cryptosporidiosis, an abdominal infection. Symptoms of infection include nausea, diarrhea, and abdominal cramps. Most healthy individuals can overcome the disease within a few weeks. However, immuno -compromised people are at greater risk of developing life-threatening ill- ness. We encourage immuno -compromised indi- viduals to consult their doctor regarding appro- priate precautions to take to avoid infection. Cryptosporidium must be ingested to cause dis- ease, and it may be spread through means other than drinking water. Reporting on additional monitoring If your system has performed voluntary monitoring that indicates the presence of non- regulated contaminants in the finished water, we strongly encourage you to report any results that may indicate a health concern. Public knowledge of potential problems is in the interest of you and your customers. We con- sider any detection above a proposed MCL or health advisory level to indicate concern. Call E:3 the Safe Drinking Water Hotline or visit EPA's web site for this information. For these con- taminants, EPA recommends that the report contain: • the results of monitoring • an explanation of the significance of the results, noting the existence of the health advisory or proposed MCL. �1 Item 5 • Compliance with other drinking water regulations If your water system violated one of the following rules during the year covered by the report, your CCR must describe the violation(s). Just as you must explain the potential health effects of any MCL violation, you must provide a clear and readily understandable explanation of any other violation, potential adverse health effects (if any), and the steps the system has taken to correct the violation. • Treatment techniques (1) Filtration and disinfection (Surface Water Treatment Rule requirements). If the violation was a failure to install adequate filtration or disinfection equipment or processes, or there was a failure of that equipment or process, include the following language: Inadequately treated water may contain disease -causing organisms. These or- ganisms include bacteria, viruses, and parasites, which can cause symptoms such as nausea, cramps, diarrhea, and associated headaches. (2) Lead and copper control requirements. If the violation was a failure to meet corrosion control treatment, source water treatment, or lead service line requirements, include the health ef- fects language for lead or copper list- ed in Appendix A. Item 6• Educational information Your CCR must prominently display the following statements: (1) 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. More information about contaminants and potential health effects can be obtained by calling the EPA's Safe Drinking Water Hotline (1-800-4264791). E (3) Acrylamide and Epichlorohydrin --If you violate either treatment technique, you must include the relevant health effects language from Appendix A. Monitoring and reporting of compliance data. If your system failed to take the sam- ple on time, the report should say "health effects unknown". If your system took the samples accurately and on-time, but mailed the results late, you don't need to discuss health effects. • Record keeping requirements • Special monitoring requirements • Violation of a variance, an exemption, or an administrative or judicial order Variances and Exemptions If your system operated under a variance or exemption at any time during the year covered by the report, include an explanation of the variance or exemption, the date that it was issued, why it was granted, when it is up for renewal, and a status report on what the system is doing to remedy the problem. Also, tell your customers how they may participate in the review of the variance or exemption. (2) Some people may be more vulnerable to con- taminants in drinking water than the general population. Immuno -compromised persons such as persons with cancer undergoing che- motherapy, persons who have undergone organ transplants, people with HIV/AIDS or other immune system disorders, some elderly, and infants can be particularly at risk from infec- tions. These people should seek advice about drinking water from their health care provid- ers. EPA/CDC guidelines on appropriate means to lessen the risk of infection by Crypto- sporidium and other microbial contaminants are available from the Safe Drinking Water Hotline(] -800-426-4791). Your report must contain basic information about drinking water contaminants. Use the following language, or you may write your own comparable language that better fits your spe- cific local situation: The sources of drinking water (both tap water and bottled water) include rivers, lakes, streams, ponds, reservoirs, springs, and wells. As water travels over the surface of the land or through the ground, it dissolves naturally -occurring minerals and in some cases, radioactive material, and can pick up substances resulting from the presence of animals or from human activity. Contaminants that may be present in source water include: • Microbial contaminants, such as viruses and bacteria, which may come from sewage treatment plants, septic systems, agricultural livestock opera- tions, and wildlife. • Inorganic contaminants, such as salts and metals, which can be naturally -occurring or result from urban stormwater runoff`, industrial or domestic wastewater discharges, oil and gas production, mining, or farming. • Pesticides and herbicides, which may come from a variety of sources such as agriculture, urban stormwater runoff, and residential uses. • Organic chemical contaminants, including synthetic and volatile organic chemicals, which are byproducts of industrial processes and petroleum production, and can also come from gas stations, urban stormwater runoff, , and septic systems. • Radioactive contaminants, which can be naturally -occurring or be the result of oil and gas production and mining activities. In order to ensure that tap water is safe to drink, EPA prescribes regulations which limit the amount of certain contaminants in water provided by public water systems. Food and Drug Adminis- tration regulations establish limitsfor contaminants in bottled water which must provide the same protection for public health. Special requirements for Nitrate, Lead, Arsenic, and Trihalomethanes If your water contains: Nitrate above 5 ppm (50 % of the MCL), but below 10 ppm (the MCL); Arsenic above 25 ppb (50 % of the MCL), but below 50 ppb (the MCL); and/or Lead above 15 ppb (the Action Level) in more than 5%, but fewer than 10%, of sites sampled [if your system samples fewer than 20 sites and has even one sample above the AL, you'll need to include the standard explanation for an AL exceedence ], you must include in your report the relevant special educational statement listed below about that contaminant. Nitrate: Nitrate in drinking water at levels above 10 ppm is a health risk for infants of less than six months of age. High nitrate levels in drinking water can cause blue baby syndrome. Nitrate levels may rise quickly for short periods of time because of rainfall or agricultural activity. If you are caring for an infant, you should ask for advice from your health care provider. 10 Arsenic: EPA is reviewing the drinking water standard for arsenic because of special concerns that it may not be stringent enough. Arsenic is a naturally -occurring mineral known to cause cancer in humans at high concentrations. Lead: Infants and young children are typically more vulnerable to lead in drinking water than the general population. It is possible that lead levels at your home may be higher than at other homes in the community as a result of materials used in your home's plumbing. If you are concerned about elevated lead levels in your home's water, you may wish to have your water tested and flush your tap for 30 seconds to 2 minutes before using tap water. Additional information is available from the Safe Drinking Water Hotline (8004264791). If you believe that the language above is not relevant to your situation, you may adjust the language in consultation with your state. 11� r1 Trihalomethanes If your system has a running annual average ^ for trihalomethanes above 80 ppb (the new MCL set by the Stage 1 Disinfectant/ Disinfec- tion Byproducts Rule that is not in effect till You are not limited to providing only the required information in your report. You may use the report to explain (or include a diagram of) your treatment processes, source water protection efforts, or the costs of your making water safe to drink. You may include a state- ment from the mayor or general manager. Or you could educate your customers about water 2001) but below the current MCL of 100 ppb, you must include the health effects statement for TTHMs contained in Appendix C. You should explain to your customers how you plan to reduce this level. conservation, taste and odor issues, affiliations with programs such as the Partnership for Safe Water, and so forth. You may want to provide the address for EPA's drinking water web site (www.eRa.gov/safewater/). The only limitation on this information is that it must not interfere with the educational purpose of the report. V. What should the report look like? You don't need a fancy computer or a graphic designer to produce a CCR that is easy to read and inviting to your customers. The best way to design your report is to spend some time looking at other reports. See what catches your eye, and copy it. A few things to consider: * Write short sentences. Keep your para- graphs short, too. * Don't make your text size too small. You might want to squeeze a few extra sentences in your report, but if you add too much, people might ignore the entire report. * Give a draft of your CCR to relatives or friends who aren't drinking water experts 11 and ask them if it makes sense. Ask cus- tomers for their comments when you pub- lish the report. * Don't distract from your main message with graphics and/or pictures that don't comple- ment your message. * Be as simple and straight forward as possi- ble: Avoid acronyms, initials, and jargon. * Consider printing the report on recycled paper and taking other steps to make the report "environmentally friendly". If you hope to get your customers involved in protecting source water, set a good example for them. VI. How must a water system distribute its report? You must mail or deliver a copy of your consumer confidence report to each of your customers, and make a good faith effort to get reports to non -bill -paying consumers. Deliver your fust report by October 19, 1999, and your reports in years after that by July 1. You may include the reports with water bills, if feasible, or you may send the reports as separate mailers. Keep your report on file for five years, and make it available to the public upon request. Send a copy to the director of the state drinking water program when you mail it to customers. Within three months of the report's due date, submit to the state a certification (see Appendix D) that you distributed the report, and that its information is correct and consistent with the compliance monitoring data previously submitted to the State. Send a copy to any other state agency that the state drinking water pro- gram director identifies. We also encourage you to send copies to state and local health departments, as well as local TV and radio stations and newspapers. Systems that serve 100,000 or more people must post their reports on the Internet. It is in your system's interest to spread the word about the quality of its water. Since many consumers of your water may not receive bills (people such as apartment renters), you must make serious and "good faith" efforts to reach non -bill paying consumers. A "good faith" effort means selecting the most appropriate method(s) to reach those consumers from a menu of options that your primacy agency recommends. Those options include but are not limited to: posting the report on the Internet mailing the report to all postal patrons advertising the availability of the report in newspapers, TV, and radio 12 • publishing the report in a local newspaper • posting the report in public places such as cafeterias of public buildings, libraries, churches, and schools • delivering multiple reports for distribution by single -biller customers such as apartment buildings or large private employers • delivering the report to community organi- zations Your Governor (or Tribal leader or EPA Regional Administrator in some cases) can waive the mailing requirement for water sys- tems that serve fewer that 10,000 people. You may choose to mail the report even if the Gov- ernor has issued a waiver. If you decide to use the waiver, take the following steps: • Publish the report in one or more local newspapers Inform customers, either by notification in newspapers or by other means approved by the State, that reports will not be mailed Make the reports available upon request If your system serves 500 or fewer people and the Governor waives the mailing require- ment for small systems, you do not have to publish the report in the newspaper, though you may want to do so. At least once a year, you must notify customers through a mailed, deliv- ered, or posted notice that the report is available from your water system upon request. Systems that serve 100,000 or more people must post their reports on the Internet. EPA encourages other systems to post their reports as well. Many local governments have sites where you could post your report, even if your system itself does not have a site. EPA will make links from its website (www.gRa.aov/safewater/) to all the reports of which it is aware. MIR n �u3o. < O D ny O G1 CSD "O'1 �• co co < �' H C � O o = C.

In providing these reports, EPA is not endorsing the views nor judging the accuracy of the information contained in the reports. These examples do not necessarily meet all current federal and state CCR requirements. Be sure to check with your state drinking water program since your state may have different requirements from those under which these reports were created. The first report is a hypothetical example created by EPA. The second report is provided courtesy of SERCO Labs, St Paul, MN. The third report is provided courtesy of Des Moines Water Works, Des Moines, IA. 26 CCR Example #1 Sampletown Water Quality Report - 1999 Last year, we conducted more than 500 tests for over 80 drinking water contaminants. We only detected 7 contaminants, and found only atrazine at a level higher than the state allows. As we told you in a letter at the time, our water was temporarily unsafe. For more information, see the paragraph on the back mark- ed arked Violation. This brochure is a snapshot of the quality of the water that we provided last year. Included are details about where your water comes from, what it contains, and how it compares to Environmental Protection Agency (EPA) and state standards. We are committed to providing you with information because informed customers are our best allies. For more information about your water, call 867-5309 and ask for Joe Sampson. Some people may be more vulnerable to contaminants in drinking water than the general population. Immuno -compromised persons such as persons with cancer undergoing chemotherapy, persons who have undergone organ transplants, people with HIV/AIDS or other immune system disorders, some elderly, and infants can be particularly at risk from infections. These people should seek advice about drinking water from their health care providers. EPA/CDC guidelines on appropriate means to lessen the risk of infection by Cryptosporidium and other microbial contaminants are available from the Safe Drinking Water Hotline (800-426-4791). Your water comes from three municipal wells sunk about 500 feet into an underground source of water called the Low Plain Aquifer. These wells are located west of town behind the municipal garage. The town owns the land around these wells and restricts any activity that could contaminate them After the water comes out of the wells, we treat it to remove several contaminants and we also add disinfectant to protect you against microbial contaminants. The state is performing an assessment of our source water that it complete by January2001. We will report the results to you and tell you how to get a copy of the report when it is available. Our Water Board meets on the first Tuesday of each month at 7:30 pm in the Town Hall. Please feel free to participate in these meetings. 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 More information about contaminants and potential health effects can be obtained by calling the EPA's Safe Drinking Water Hotline (800-426-4791). The sources of drinking water (both tap water and bottled water) include rivers, lakes, streams, ponds, reservoirs, springs, and wells. As water travels over the surface of the land or through the ground, it dissolves naturally -occurring minerals and, in some cases, radio- active material, and can pick up substances resulting from the presence of animals or from human activity. Contaminants that may be present in source water before we treat it include: *Microbial contaminants, such as viruses and bacteria, which may come from sewage treatment plants, septic systems, agricultural livestock operations and wildlife. *Inorganic contaminants, such as salts and metals, which can be naturall),occurring or result from urban stormwater runoff, industrial or domestic wastewater discharges, ort and gas production, mining or farrning. *Pesticides and herbicides, which may come f rom a variety of sources such as agriculture and residential uses. *Radioactive contaminants, which are naturally occurring - *Organic chemical contaminants, including synthetic and volatile organic chemicals, which are by-products of industrial processes and petroleum production, and can also come from gas stations, urban stormwater runoff, and septic systems. In order to ensure that tap water is safe to drink, EPA prescribes regulations which limit the amou- nt of certain contaminants in water provided by public water systems. We treat our water according to EPA's regulations. Food and Drug Administration regulations establish limits for contaminants in bottled water which must provide the same protection for public health. WATER QUALITY DATA The table below lists all the drinking water contaminants that we detected during the 1998 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 January 1 -December 31, 1998. The state requires us to monitor for certain contaminants less than once per year because the concentrations of these contaminants are not expected to vary significantly from year to year. Some of the data, though representative of the water quality, is more than one year old. Terms & abbreviations used below: 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 allow for a margin of safety. * Maximum Contaminant Level (MCL): the highest level of a contaminant that is allowed in drinking water. MCLS are set as close to the MCLGs as feasible using the best available treatment technology. Action Level (AL): the concentration of a contaminant which, when exceeded, triggers treatment or other requirements which a water system must follow. * n/a: not applicable * nd: not detectable at testing limit * ppb: parts per billion or micrograms per liter * ppm: parts per million or milligrams per liter * pCi/l: picocuries per liter (a measure of radiation) inorganic Contaminants Sampiatown MCL Range of Sample Violati0 Typical Source of Contaminant "MCLG-water detections -Date -'n Fluoride (ppm) 2* 4 0.98 - water additive which promotes strong teeth Nitrate as nitrogen (ppm) 10 10 6 nd-9 runoff from fertilizer use organic Chemical Contaminants w Atrazine (ppb) 3 3 3.275 .1-10 *YES* runoff from herbicide used on row crops Total Trihalomethanes 100 n/a 73 40-135 by-product of drinking water chlorination (TTHMs) (ppb) Beta/photon emitters (pCVi-) SO— 0 10 erosion of natural deposits _ m..

However, our state has set a lower MC1, to better protect human health. ** The MCI., for beta particle is 4 mm-m/year. EPA considers 50 pCi/1 to be the level of concern for beta particles. About our-Airazine violation: During March, April and May, a big surge in the use of atrazine -based herbicides by < atea.farmers caused our -water to exceed the.MCL for atrazine. We sent.a notice warning you of this problem when u • occurre& We.are.cvorking with the state and local farrners'to ensure that this neverhappens.again, and we'ate monitoring atrazine levels monthly. ' We regret exposing you to any, potential' risk You should know.that some people who drink water containing atraI=e.well in excess of the MCL over many years could experience problems with their cardiovascular, system or reproductive difficulties. If you want more information about atrazine or the violation, please callus (867-5309); Sample County's health department (423-4444), or the state drinking water office (853 -323 -3333). - About Nitrate: Nitrate in drinking water at levels above 10 ppm is a health risk for infants of less than six months of age. High nitrate levels in drinking water can cause blue baby -syndrome. Nitrate levels may rise quickly for short periods of time because of rainfall or agricultural activity. If you are caring for an infant, you should ask for advice from your health care provider. Is our water system meeting other rules that govern our operations? The state and EPA require us to test our water on a regular basis to ensure its safety. In February and May of this year, we took the samples at the required time but failed to submit the results of this monitoring to the state in a timely manner. We are reviewing our procedures to ensure that this paperwork will be submitted in a timely manner in the future. /'\ CCR Example #2 lo1 /0"*1 (More about water...

The Champlin VN'ater System provides safe and aesthetically pleasing drinking water to its residents as well as many businesses and visitors. The supply comes from groundwater wells in the Franconia, Ironton/Galcsvillc, and Mt. Simon A(luifcrs. The first well was drilled in 1974 at NVcthcrn Park. The system now includes 78 miles of water main. In its effort to supply you with the safest possible product, the City of Champlin chlorinates the water supply for disinfection of viruses and bacteria. Fluoride is also added to enhance dental protection. The levels of these two additives are monitored daily to ensure proper dosages arc being added. Champlin utilizes an odd -even sprinkling schedule to conserve water during the peak water use summer season. According to Bob Mugaas of the Minnesota Extension Service, University of Minnesota: • Water deeply and infrequently. One inch of water per week is ideal. • Over -watering wastes your -money and also removes plant nutrients from the soil. • Excess watering can cause disease problems in your lawn: Level Substance MCL MCLG Detected 4 1.4 0 Fluoride (mg/l) 4 3.2 2000 40.190 I ihalomethanes 100 Arsenic so Barium (ugh) 2000 4 1.4 0 4.2 so 3.2 2000 40.190 Key: *Muimum Cattamirr+nt Level (ML 'l CLire highest level of con-ni :.•as...�..::-:: mimot Level Goal (MCLG): The level or a wurn,dmnt in tltirJcittg water -ppb: parts per billiat of mireograrns per liter lug1l) •ppm: pans pet millic Iron and Manganese Iron is an abundant and widespread constituent of rocks and Oils in Minnesota. At sufficient concentrations, iron can adversely affect the taste of water and beverages and can leave rust -colored stains on laundry, plumbing fixtures, and porcelain. Manganese, while less abundant than iron, causes similar problems. can cause a bitter metallic taste in water and leave visible black "specks" in ice cubes. Manganese can also produce staining and cause the water to have a brown or black discoloration. 'Ib minimize the effects of these minerals, the City of Champlin has installed a treatment plant that will remove iron and manganese.

The purpose of this report is to advance consumers understanding of drinking water and heighten awareness of the need to protect precious water resources. For the 1997 calendar year (1998 results will be Published in 1999), no contaminants were detected at levels that exceeded federal standards. Four components were detected in trace amounts well below Federal Safe Drinking Water Act Maxirnurn Contaminant Level Goals set for public water systems throughout the country. The table included in this report lists the detected constituents. Their presence doesn't necessarily indicate that water poses a health risk. Sonne people may be more vulnerable to substances found in drinking water than the general population. Immumo-compromised persons such as persons with cancer undergoing chemotherapy, persons who have undergone organ transplants, people with HIVIAIDS or other immune system disorders, some elderly, and infants can be particularly at risk frorn infections. These people should seek advice about drinking water from their health care providers.

We supply Des Moines and the communities listed aoove with the highest quality drinking water. *Des Moines Water Works believes that the best way to assure you that your drinking water is safe and reliable is to provide you with accurate facts. This Consumer Confi- dence Report will explain where Mir water comes from and the treatment process. The chart contained in this report shows that all contaminants detected in your water are within Environmental Protection Agency (EPA) guidelines. There are three sources of water fulfilling the needs of Des Moines Water Works cus- tomers. ApproAmatey two-thirds is supplied by either the Raccoon or Des Moines Rivers. The remaining one-third comes from the in- filtration gallery system (shallow ground wo- ter). *Powdered activated carbon is fed into the river water for removal of man-made and natural organic chemicals. The water is then pretreated to remove dirt and debris and cornbined with water from the infiltro- tion gallery system. The combined water then flows into softening basins. The pH of the water is adjusted before the final filtering process. The water is passed through layers of sand and various sizes of gravel to re- move any remaining particles. Des Moines Water Works activates its nitrate removal fo- ciHy to remove this contaminant from your water during periods of possible nitrate level increases. After this final phase, fluoride is added to aid in the prevention of tooth de - Cay and chlorine is added as a disinfectant to kill bacteria. The clean water is stored in a clear well until pumped into the pipes of the disMuhm system. •Des Moines Water works laboratory and water production staff collect and test water samples from throughout the system several times a day. These tests ensure that the proper chemicol levels are maintained and that the water remains free of unwonted contaminants.
