Hazardous Sites near Londonderry, NH
There are eight Superfund sites in Rockingham County, NH. Superfund sites, like Beede Waste Oil in Plaistow, NH, are areas that have been contaminated with hazardous substances. If not for the cleanup efforts orchestrated by the EPA, these sites could endanger people living in nearby communities.
The EPA uses the Hazardous Ranking System (HRS) to quantify the risk a contaminated site poses to human health and the environment. Sites assigned HRS scores of 28.5 or greater qualify for placement on the National Priorities List (NPL), and are eligible to receive federal funding for cleanup efforts.
Before the EPA deletes a site from the NPL, it conducts reviews to ensure the cleanup was sufficient. As a result, some sites remain on the active site list long after cleanup activities are complete.
