If you have any questions regarding this, please feel free to contact me at the City offices. Sincerely, 'Steven M. Smart, P.E. Public Works Director 61"TV4191 City of Chubbuck Annual Drinking Water Quality Report June 2006 Your Water is safe to drink! The City of Chubbuck is pleased to present its Water Quality Report for 2005. This report contains important information about the quality of your drinking water. We are required to prepare and distribute this Consumer Confidence Report. It is part of the requirements of the 1996 amendments to the Safe Drinking Water Act. The City is committed to providing safe drinking water to its customers. The City has attempted to make this report informative and readable. This report shows our water quality and what it means. If you have questions about the report or your drinking water, please call the City Public Works offices at (208) 237-2430, and further assistance will be provided. If you would like to have input on how your drinking water is provided, you may either call the number above, or attend the City Council meetings. The Chubbuck City Council meets at 7:30 P.M. every second and fourth Tuesday of the month. The meetings are held in the City Offices located at 5160 Yellowstone Ave. Please feel free to participate in these meetings. Your drinking water comes from four wells drilled into the Lower Portneuf River Aquifer. They are located throughout the city. This water is very high quality and the only treatment given is to chlorinate it. Well No. 4 does have a special treatment system. It is described below. The only man -caused contaminant in the water is Tetrachloroethylene (PCE or PERC). The source of PCE contamination is unknown at this time. We are able to treat the water to remove high concentrations of PCE. The City has constructed a treatment plant at Well No. 4 that removes PCE using an air stripping process. The City is pleased to report that our drinking water meets, or exceeds all federal and state drinking water standards. The City routinely monitors for constituents in your drinking water. Benchmark testing has also been done for additional constituents. This is done in accordance with State and Federal laws. All drinking water, including bottled water, may be reasonably expected to contain at least small amounts of some constituents. It is important to remember that the presence of these constituents does not necessarily pose a health risk. More information about contaminants and health effects can be obtained by calling the EPA's Safe Drinking Water Hotline (800-426-4791). 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 mans to lessen the risk of infection by Cryptosporidium and other microbial contaminants are available from the 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, radioactive material, and can pick up substances resulting from the presence of animals or from human activity. The state has completed an assessment of our source water. That report is available for review at the City Offices. 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 Administration (FDA) regulations establish limits for contaminants in bottled water which must provide the same protection for public health. 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 other homes in the community as a result of materials used 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 (1-800-426-4791). 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 caring for an infant, you should ask advice from your health care provider. 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 naturally -occurring or result from urban storm water 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 by- products 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. The table below shows the results of our water quality monitoring for the period January 1, 2005 to December 31, 2005. 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 representative, are more than one year old. We have included test results for only those constituents found in our drinking water. Most constituents tested for were not found. In the table, you will find many terms and abbreviations you might not be familiar with. To help you better understand these terms, we have provided the following definitions: Maximum Contaminant Level (MCL): The highest level of a contaminant that is allowed in drinking water. Maximum Contaminant Level Goal (MCLG): The level of a contaminant in drinking water below which there is no known or expected risk to health. MCLG's allow for a margin of safety. Non -Detects (ND): Laboratory analysis indicates that the constituent is not present. Parts per Million (ppm) or Milligrams per liter (mg/1): one part per million corresponds to one minute in two years or a single penny in $10,000 Parts per Billion (ppb) or Micrograms per liter (ug/1): one part per billion corresponds to one minute in 2000 years or a single penny in $10,000,000. Picocuries per liter (pCi/L): measure of radioactivity in water Million fibers per liter (MFL): measure of the presence of asbestos fibers that are longer than 10 micrometers. Action Level: the concentration of a contaminant which, if exceeded, triggers treatment or other requirements which a water system must follow.

Special Compliance Violations Treatment techniques: Monitoring/Reporting: Public notification/Record keeping: Special monitoring requirements: Administrative or judicial orders: Consent orders: Notice of Violations (NOV): IV. Definitions Maximum Contamination 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 Contamination 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 mar in of safety. Treatment Technique: A required process intended to reduce the level of a contaminant in drinking water. Action Level: The concentration of a contaminant, which, if exceeded, triggers treatment, or other requirements which a water system must follow. Maximum Residual Disinfectant Level (MRDL): The highest level of disinfectant allowed in drinking water. There is convincin evidence that addition of a disinfectant is necessary for control of microbial contaminants. Maximum Residual Disinfectant Level Goal (MRDLG): The level of a drinking water disinfectant below which there is no known or expected risk to health. MRDLGs do not reflect the benefits of the use of disinfectants to control microbial contamination. V.

Sampling History PWS NUMBER ❑ ❑ ID6030008 PWS NAME: ❑ ❑ ❑ CHUBBUCK CITY OF Total Records: 18 • Sampling history is only listed for systems which are practicing chlorination on a full-time basis. • Public water systems that are required to collect one sample for disinfection byproducts once every year, or every three years, are only required to report the most recent detections for disinfection byproducts. If the most recent sampling was a non -detect for the contaminants, then it is not necessary to report any disinfection byproduct sampling. Note: If a contaminant is listed with a "Y" (meaning ❑Yes❑) in the ❑non -detect❑ column, this means that sampling results showed a ❑non -detect❑ ❑ that is to say, the contaminant was not detected. • If a public water system collects more than one sample per year, the system must report the average of Total Trihalomethanes and Haloacetic Acids Group 5 over the 2005 calendar year. The highest level detected, and the range for each contaminant must also be reported. • Required Language. If a system reports a detection, the system must give the major sources of the contaminant. To report this information, go to Appendix A of the CCR template , find the contaminant, and copy the information from the OMa4jor Sources in Drinking Water[] column and place it in your CCR. If the system has exceeded the MCL (maximum contaminant level) value of a contaminant, go to Appendix A of the CCR template , find the contaminant, and copy the information from the ❑Health Effects Languages column and place it in your CCR.
