Board approves well agreements

WashCo_logoSeparate agreements on water-monitoring wells at two Washington County parks were approved Tuesday by the County Board of Commisisoners.

One agreement gives 3M right of entry into the Lake Elmo Park Reserve to collect groundwater perfluorochemical data from the Jordan aquifer through a monitoring well in the Whistling Valley area of Lake Elmo south of Eagle Point Lake in the park.
The agreement requires all activities 3M conducts on park property be done at the company’s expense and risk.

The first agreement between 3M and the county expired at the end of 2010 and 3M asked to extend the pact to Dec. 31, 2014. The company will restore land at the monitoring well site to its previous condition when monitoring is finished.

The second agreement allows the Minnesota Pollution Control Agency to install a permanent groundwater monitoring well in open green space on the southern part of Square Lake Park.

The MPCA well is part of a network providing long-term information about state groundwater quality. The agency plans to maintain and monitor the Square Lake Park well indefinitely and sampling results and data collected will be public information after data is validated.

The MPCA is responsible for costs and risks associated with well installation and monitoring and will minimize interference with the county’s use of the property. The agency also agrees to restore any disturbed property to as close to original condition as possible.

The agreement can be terminated by either the MPCA or county with 60 days written notice to the other party.
