The University of Minnesota Geological Survey Office will drill a test hole at the Lake Elmo Park Reserve to collect rock and sediment samples for a new geologic atlas of Washington County after the Board of Commissioners approved a drilling license Tuesday.
The MGS, with cooperation from the county’s Department of Public Health and Environment, is drilling test holes for rock and sediment collection at several county sites. Information collected from the drilling is used by MGS and the state Department of Natural Resources to create geologic and groundwater maps.
Drilling the Lake Elmo Park Reserve test hole is expected to take two to four days. MGS will pay costs to restore the drill site to its original condition when the project is finished.
Geologic atlases provide essential information for ground water resources management and applications such as monitoring, water allocation, permitting, remediation and well construction. Other information in atlases includes aquifer properties and boundaries, connections of aquifers to land surface and surface water resources. Atlases also offer a broad range of information on the county’s geology, mineral resources, construction materials and natural history.
County gets bridge funds
Washington County will receive more than $247,000 for partial payment to replace the County State Aid Highway 21 bridge over Valley Creek in Afton after the Board of Commissioners approved an agreement with the state Tuesday.
The county receives the money through the local bridge replacement program. Total project cost is more than $455,000, with additional money from the county state aid fund.
Commissioners also awarded the contract for the Afton bridge project to Minnowa Construction, Inc. of Harmony, Minn.
Two named to watershed board
Two men were named to three-year terms on the South Washington Watershed District board Tuesday by the Board of Commissioners.
Dennis Hanna of Grey Cloud Island Township and Brian Johnson of Woodbury will serve terms expiring May 1, 2016.
Watershed districts are set up by state law to oversee water-related issues and protect and regulate groundwater use.
