The Minnesota Department of Natural Resources will collect water samples from about 180 wells in St. Louis County for use in the development of a Groundwater Atlas of St. Louis County. Selected well owners will be contacted by mail or phone to request permission to sample their wells. The process involves collecting a water sample from an outside spigot or hydrant for laboratory analysis.
Dozens of different water components are analyzed to determine the natural chemistry of aquifers. Participation is voluntary and owners will receive a report of the laboratory results. Sample well locations are shown on the maps produced for the atlas, but no contact or ownership information is included in the data. There is no cost to well owners. Wells are selected based on geology, location, well depth and well construction. Participation will help hydrologists create county maps and descriptions of groundwater distribution, movement, conditions, and the pollution sensitivity of aquifers. The final atlas products will be available as printed maps, reports and geographic information system files available on the web.
