Pat00e 12 Lokals Government Thursday, May 26, 2011 Tri-County News Kimball, MN 7.- IZ:.  .?- Consumer Confidence Report 2010 A copy of the water report will be available upon request at City Hall or online at <>. Our supply contains high levels of iron and manganese, which do cause discoloration and / or sedimen- tation. Our water treatment plant removes the majority of the iron and manganese. The remainder is gradu- ally deposited in the distribution system. We have developed a hydrant flushing plan to help remove any set- tled deposits. Please help by reporting water quality problems to the city office or by calling (320)980-4904. Your comments will help us target problem areas and provide the best quality water with the least amount of labor cost. Sincerely, Chad Johnson, City of Kimball Public Works City of Kimball 2010 Drinking Water Report The City of Kimball is issuing the results of monitoring done on its drinking water for the period from January 1 to December 31,2010. The purpose of this report is to ad- vance consumers' understanding of drink- ing water and heighten awareness of the need to protect precious water resources. Source of Water The City of Kimball provides drinking water to its residents from a groundwater source: two wells ranging from 48 to 59 feet deep, that draw water from the Quaternary Water Table aquifer. The water provided to customers may meet drinking water standards, but the Minnesota Department of Health has also made a determination as to how vulnerable the source of water may be to future con- tamination incidents. If you wish to obtain the entire source water assessment regard- ing your drinking water, please call (651) 201-4700 or (800) 818-9318 (and press 5) during normal business hours. Also, you can view it on line at ran. us/divs/eh/water/swp/swa. Call Chad at (320) 080-4904 if you have questions about the City of Kimball drink- ing water or would like information about opportunities for public participation in decisions that may affect the quality of the water. Results of Monitoring No contaminants were detected at lev- els that violated federal drinking water standards. However, some contaminants were detected in trace amounts that were below legal limits. The table that follows shows the contaminants that were detect- ed in trace amounts last year. (Some con- taminants are sampled less frequently than once a year; as a result, not all con- taminants were sampled for in 2010. If any of these contaminants were detected the last time they were sampled for, they are in- cluded in the table along with the date that the detection occurred.) KEYTO ABBREVIATIONS; MCLG-Maximum Contaminant Level Goal: 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. MCL-Maximum Contaminant Leveh 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. MRDL-Maximum Residual Disinfectant Level. MRDLG-Maximum Residual Disinfectant Level Goal. AL-Action Level: The concentration of a contaminant which, if exceeded, triggers treatment or other requirement which a water system must follow. 90th Percentile Level: This is the value obtained after disregarding 10 percent of the samples taken that had the highest levels. (For example, in a situation in which 10 samples were taken, the 90th percentile level is determined by disregarding the highest result, which represents 10 percent of the samples.) Note: In situations in which only 5 samples are taken, the average of the two with the highest levels is taken to determine the 90th percentile level. ppb-Parts per billion, which can also be expressed as micrograms per liter (pg/1). ppm-Parts per million, which can also be expressed as milligrams per liter (mg/1).

City of Kimball is responsible for pro- viding high quality drinking water, but cannot control the variety of materials used in plumb- ing components. When your water has been sitting for several hours, you can minimize the po- tential for lead exposure by flushing your tap for 30 seconds to 2 minutes before using water for drinking or cooking. If you are concerned about 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 Safe Drinking Water Hotline or at safewater/lead. Some contaminants do not have Maximum Contaminant Levels established for them. These unregulated contaminants are assessed using state standards known as health risk limits to deter- mine if they pose a threat to human health. If unacceptable levels of an unregulated contaminant are found, the response is the same as if an MCL has been exceeded; the water system must inform its customers and take other corrective actions. In the table that follows are the unregulated con- taminants that were detected: l.eve Fonnd Contaminant (units) Sodium (ppm) (05/14/2009) Sulfate (ppm) (0511412009) Range (201 O) Average / Result Typical Source of Contaminant N/A 6.6 Erosion of natural deposits.

Compliance with National Primary Drinking Water Regulations The sources of drinking water (both tap water and bottled water) incIude 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 cas- es, radioactive material, and can pick up substances resulting from the presence of ani- mals 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 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 agricul- ture, urban storm water 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. In order to ensure that tap water is safe to drink, the U. S. Environmental Protection Agency (EPA) prescribes regulations which limit the amount of certain contaminants in water provided public water systems. Food and Drug Administration regulations estab- lish limits for contaminants in bottled water which must provide the same protection for public health. Drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some contaminants. The presence of contaminants does not nec- essarily indicate that water poses a health risk. More information about contaminants and potential health effects can be obtained by calling the Environmental Protection Agency's Safe Drinking Water Hotline at (800) 426-4791. Some people may be more vulnerable to contaminants in drinking water than the gener- al population, lmmuno-compromised persons such as persons with cancer undergoing che- motherapy, persons who have undergone organ transplants, people with HIV/AIDS or oth- er 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 Cryptospo- ridium and other microbial contaminants are available from the Safe Drinking Water Hot- line at (800) 426-4791.
