ST. PAUL, MN--The Minnesota Department of Natural Resources is looking to collect and analyze water samples from about 90 wells in Becker County this spring. DNR Hydrogeologist Randy Bradt from the St. Paul office is heading up the collection of samples.**

Bradt says DNR staff will contact county residents to request permission for well sampling, which involves collecting a water sample and measuring the depth to water in each well.**

Tests will profile the general chemical characteristics of area groundwater and will also show approximately how long the water has been underground. Geology, location, well depth and well construction will determine the selection of wells for sampling. Owners of sampled wells will receive a report of the laboratory results for the water sample collected from their well.**

Bradt says preserving the long-term quality of the region’s surface water and groundwater requires that policymakers have access to accurate information based on sound scientific principles. A county geologic atlas is a valuable tool for county planners, resource managers and other local government staff when making general planning, land use management and water resource protection decisions.

The Minnesota Geological Survey has already published Part A of the atlas, which illustrates details of each county’s geology. In 2020, the DNR will publish the groundwater portion of the atlas (Part B). The Part B reports will include maps and descriptions of the distribution and movement of groundwater, cross sections illustrating groundwater conditions, and the pollution sensitivity of aquifers in the county.
