EPA Changes Approach to Meddybemps Superfund Site

The Eastern Surplus Superfund Site in Meddybemps – designated as a national priority for the EPA based on its level of toxicity – will be handled with a new approach going forward, the EPA has announced. The major change is a shift from using chemical reagents to enhanced bioremediation to treat the site. The modifications do not fundamentally alter the remedy with respect to scope, performance or cost. A public meeting to discuss the change will be held on August 9th.

Previous environmental investigations revealed that soil and groundwater at the Eastern Surplus Co. Site had been contaminated with at least 31 hazardous materials, including PCBs, solvents, heavy metals, acids, paints, oils, asbestos and pesticides. Contamination at the privately-owned site could endanger the public health of an estimated 200 local residents who rely on the groundwater as their drinking water. The site also posed an environmental threat to natural resources such as Meddybemps Lake, Denny’s River and a nearby national refuge. The site was listed on the National Priorities list and became designated a Superfund Site in 1996.

The proposed changes for the Eastern Surplus Company Superfund Site are as follows: The Explanation of Significant Differences (ESD) changes the selected remedy with the suspension of the operation of the extraction and treatment system for further in situ application and the change of the application material from chemical reagents to enhanced bioremediation. The basis for this change is the successful demonstration of enhanced bioremediation through the 2012-2013 pilot study and post-injection monitoring.

On Wednesday, August 9, 2017 at 6:00 p.m. at the Meddybemps Community Hall in Meddybemps, Maine, EPA will hold an informational public meeting to explain the proposed changes to the remedy at the Eastern Surplus Superfund site and solicit public feedback. In addition, EPA will be accepting comments on the proposed ESD from August 9, 2017 through September 8, 2017.  Comments may be sent to Terrence Connelly, EPA Project Manager at connelly.terry@epa.gov.
