Waste Site Cleanup & Reuse in New England

Goodall Mills Parking Area, Sanford, Maine

Removal action at Goodall Mills Parking Area, Sanford, Maine

The Goodall Mills Parking Area site at 10-12 High St. in Sanford is in a residential and commercial area with about 4,500 people living within a half mile. The eastern portion of the site has been developed into a multi-building community center and parking area. The western portion contains two former mill buildings occupied by several small businesses.

An on-going release of #6 fuel oil from two storm drains that discharge into the Mousam River was coming from oil-contaminated soil leaching into the drain pipes. The source of the oil was a six-inch fuel line and 550,000-gallon underground storage tank operated by the former Goodall Mills. The fuel line and tank were no longer used. The Goodall Mills were built in the 1890s as wool mills and operated into the late 1900s. The mill was used by several small businesses including a furniture manufacturer and an auto detailer when the oil release was reported. Part of the site had been subdivided and redeveloped into an office space/daycare complex.

In May 2008, the Maine Department of Environmental Protection asked EPA to help address the on-going release of fuel oil from the two storm drains. EPA went to the site June 1, 2009 to begin the cleanup. Contaminated soil was removed in mid 2009 and recycled in Eliot, Maine. Groundwater that was contaminated was pumped from the excavation and treated on-site before it was discharged to the storm drain.

From July to October of 2010, EPA and its contractors lined the inside of the old clay storm water pipe to stop or minimize the infiltration of oily water into a storm water pipe and subsequently the Mousam River; cleaned the oil out the under-flow dam; disposed of oily wastes stored in 55-gallon drums generated at the end of the project; and returned management of the site to DEP.

EPA also collected groundwater samples; excavated and disposed of contaminated soil and removed or treated impacted groundwater to stop oil from entering storm drains and the Mousam River. The agency also replaced old storm drain with a pipe that will keep contaminants from entering the drain.
