PWSID: 1020035 City of Ramsey 2005. Drinking Water Report The City of Ramsey is issuing the results of monitoring done on its drinking water for the period from January 1 to December 31, 2005. The purpose of this report is to advance consumers' understanding of drinking water and heighten awareness of the need to protect precious water resources. SOURCE OF WATER The City of Ramsey provides drinking water to its residents from a groundwater source: six wells ranging from 316 to 390 feet deep, which draw water from the Franconia and Franc oni a- Ironton- Galesville aquifers. The water provided to customers may nieet drinking water standards but the Minnesota Department of Health has determined that one or more of the sources of water is potentially susceptible to contamination. If you wish to obtain the entire source water assessment regarding your drinking water, please call 651-201-4670 or 1-800-818-9318 (and press 5) during normal business hours. Also, you can view it on line at www.health.state.mn.us/divsJehlwater/swp/swa. Call John Nelson at 763-433-9861 if you have questions about the City of Ramsey drinking 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 levels 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 detected in trace amounts last year. (Some contaminants are sampled less frequently than once a year; as a result, not all contaminants were sampled for in 2005. If any of these contaminants were detected the last time they were sampled for, they are included in the table along with the date that the detection occurred.) Key to Abbreviations: MCLG _ Maximum Contaminant Level Goal: The level of a contaminant in drinking water below which there is no know~ or expected risk to health. MCLGs allow for margin of safety. MCL _ Maximum Contaminant Level: 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 Levela 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 higl)est 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.) 1.
