Hazardous Sites near Lynn, MA

There are four Superfund sites in Essex County, MA. Superfund sites, like Creese & Cook Tannery (Former) in Danvers, MA, 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.

Radon Levels in Lynn, MA Area

Air quality inside your home can be impacted by a number of factors, including the presence of hazardous substances in building materials (asbestos, lead, formaldehyde, etc.) and local radon levels.

Radon is a naturally occurring gas you cannot see or smell. It can build up inside your home and negatively impact your indoor air quality as well as your health.

To provide a guideline, the EPA assigned one of three zones to each U.S. county and county equivalent:

  • Zone 1 (higher radon levels)
  • Zone 2 (moderate levels)
  • Zone 3 (lower levels)

The average indoor radon reading in Essex County, MA is predicted to be higher than 4 picocuries per liter (pCi/L), so the county has been assigned EPA Radon Zone 1.
