Maine site added to superfund list

The U.S. Environmental Protection Agency (EPA) has finalized the addition of the Leeds Metal Site in Leeds, Maine to the Superfund National Priorities List (NPL). The Leeds Metal Site is one of 12 added to the NPL in September. The site has received letters of concurrence from state officials supporting the NPL listing.

The NPL is a national list of sites that require further investigation and potential cleanup in order to protect human health and the environment in the long term.

Operations at the Leeds Metal site date back to the 1800s, however little is known about specific activities prior to 1969. Between 1969 and 1984 scrap metal recovery processes took place, performed by a series of operators, after which the site was inactive and appears to have remained abandoned. Gasoline and other fluids were dumped directly onto the ground and as many as 100 drums were staged along the tree line in the southern part of the site.

The Maine Department of Environmental Protection (MDEP) has removed drummed waste and an abandoned transformer; sampled soil; sampled nearby private drinking water wells to identify possible off-site migration of wastes; overseen investigations to assess the site and groundwater in the area; and installed carbon filtration devices at five homes with volatile organic compound contamination exceeding state health benchmarks.
