Annual Drinking Water Annual Water Quality Report for the period of January I to December 31, 2010 This report is intended to provide you with important information about your drinking water and the efforts made by the. MOUNT PULASKI water system to provide safe drinking water. The source of drinking water used by MOUNT PULASKI is Ground Water.

Source of Drinking Water The sources of drinking water (both tap water and bottled water) include rivers, lakes, streams, ponds, reservoirs, springs, and groundwater Quality Report wells, As water travels over the surface of the land or through the ground, it dissolves naturally-occurdng minerals and, in some cases, radioactive mate- rial, and can pickup substances result- ing 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 sys- tems, agricultural livestock operations and wildlife. Inorganic contaminants, such as salts and metals, which can be naturally occurring or restlt from urban storm water runoff, industrial, or domestic wastewater discharges, oil and gas production, mining, or farm- ing. Pesticides and herbicides, which may come from a variety of sources such as agriculture, urban storm water runoff, and residential uses. Organic MOUNT PULASKI IL1070400 chemical contaminants, including syn- thetic and volatile organic chemicals. which are by-products of industrial processes and petroleum production, and can also come from gas stations, urban storm water runoff, and septic systems. Radioactive contaminants, which can be naturally-occurring or be the result of oil and gas production and mining activities. Ddnking water, including bottled water, may reasonably be expected to con- tain at least small amounts of some contaminants. The presence of con- taminants 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 at (800) 426-4791. 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 publi# water sys- tems. FDA regulations establish limits for contaminants in bottled water which must provide the same protection for public health. Some people may be more vulnerable to contaminants in drinking water than the general popu- lation. Immuno-compremised persons such as persons with cancer undergo- ing chemotherapy, persons who have undergone organ transplants, people with HIV/AIDS or other immune system disorders, some eldedy and infants can be particularly at risk from infections. These people should seek advice about drinking water from their health care providers. EPNCDC 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). If present, elevated levels of lead can cause serious health problems, especially for pregnant women and young children Lead in drinking water is primarily from materials and compo- nents associated with service lines and home plumbing. We cannot control the vanety of materials used in plumbing components. When your water has been sitting for several hours, you can minimize the potential for lead exposure by flushing your tap for 30 seconds to 2 minutes before using water for ddnking or cooking. If you are concerned aboul lead in your water, you may wish to have your water tested Information on lead in drinking water, testing methods, and steps you can take to minimize exposure is available from the sate Drinking Water Hotline or at http;//www.epa.gov/safe- water Source Water Assessment A Source Water To determine Mt.

ALGs allow for a margin of safety. Action Level: The concentration of a con- taminant which, if exceeded, tdggers treatment or other requirements which a water system must follow. Lead and Copper Date Sampled MCLG Action Level (AL) 90th Percentile # Sites Over AL Units Violation Likely Source of Contamination Copper 1.3 1.3 0.0077 0 ppm N Erosion of natural deposits; Leaching from wood preservatives; Corrosion of household plumbing Water Quality Test Results systems, Maximum'Contaminant Level Goal or 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 or 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 residual disinfectant level goal or 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 contaminants. Maximum residual disinfectant level or MRDL: The highest level of a disinfectant allowed in ddnking water. There is convincing evidence that addition of a disinfectant is necessary for control of microbial contami- nants. Definitions: The following tables contain scientific terms and measures, some of which may require explanation.ppb: micrograms per liter or parts per billion - or one ounce in 7,350,000 gallons of water, na: Not Appli- cable.

We are pleased to announce, that once again we do-not have any Violations of the IEPA regulations during this past year. We invite all of our water customers to have an active Part in protecting our valuable water source. Everyone is invited to attend any of our City Council Meetings, which are the second and fourth Tuesdays of each month. The meetings are held in the beckroom of City Hall and commence at 6:30 pro. We are approaching the MCL for Nitrate in our Water Supply. If the trend continues, we may be forced to build a Water Treatment Plant to keep our water below the MCL for Nitrate. Further discussions and information will be made available as further testing results are received.
