Source of Water CITY OF RAMSEY 2004 DRINKJNG 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, 2004 the purpose of this report is to advance consumers' understanding of drinking water and heighten awareness of the need to protect precious water resources. The City of Ramsey provides drinking water to its residents from a groundwater source: five wells ranging from 316 to 345 feet deep, that draw water from the Franconia and Franconia - Ironton - Galesville aquifers. The water provided to customers may meet 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- 215 -0800 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 / divs /eh /water /swp /swa. Contact John Nelson at 763 - 427 -8254 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 2004. 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 known 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 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. pCi /1— PicoCuries per liter (a measure of radioactivity). ppb — Part per billion, which can also be expressed as micrograms per liter (ug/1). ppm — Parts per million, which can also be expressed as milligrams per liter (mg /1). nd — No Detection. N/A —Not applicable (does not apply). Continued on Page 10 When all else fails, read the instructions. — Anonymous
