Winona Groundwater Contamination Site (Amended Decision Document) - Remediation


We invite you to comment on the draft Minnesota amended decision document for the Winona groundwater contamination superfund site located at 1405 Gilmore Avenue in Winona.


The site was formerly used as a service station and dry cleaning business. Volatile organic compounds have been identified in soil and groundwater from the site. A groundwater treatment system was installed to the east of the area in 1994. The system was shutoff in 2021 to complete a test, and is unable to resume operation. As an interim measure, we have increased the groundwater monitoring frequency to evaluate off-site risk while the treatment system remains off-line.


To clean up the remaining contamination at the site, we are recommending the construction and implementation of an electrokinetic-enhanced delivery system to treat shallow soil. The system creates an electric field within the soil which is used to carry a cleanup material to the contamination.


We are seeking written comments from the public before the decision document is finalized.
