Hazardous Sites near Dover, NH

There are four Superfund sites in Strafford County, NH. Superfund sites, like Somersworth Sanitary Landfill in Somersworth, 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.

Air Quality in the Dover, NH Area

The two most widespread forms of air pollution are ozone (smog) and particle pollution (soot). Exposure to these harmful pollutants, for even just a short period, can have adverse effects on your health.

Thanks to data collected by air monitoring equipment located across the country, the American Lung Association (ALA) is able to assess and track our air quality using three metrics:

  • Ozone
  • Short-term Particle Pollution
  • Year-round Particle Pollution

In their 2019 annual report, the ALA rated the air quality in Strafford County, NH as follows:

Ground-Level
Ozone Pollution

Grading Scale: A-F

Short-Term
Particle Pollution

Grading Scale: A-F

Year-Round
Particle Pollution

Grading Scale: Pass/Fail

DNC (Data Not Collected): Data on associated pollutants were not collected in this county or county equivalent.
INC (Incomplete): Associated pollutants are being monitored in this county or county equivalent, but data were insufficient to assign a grade.

Radon Levels in Dover, NH 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)

Indoor radon readings in Strafford County, NH are expected to average from 2 to 4 picocuries per liter (pCi/L), so the county has been assigned EPA Radon Zone 2.

EPA Radon Zone

According to the EPA, you should consider acting to reduce your home's radon level if it measures between 2 and 4 pCi/L, so if you're contemplating buying a home in Dover, NH, you should have a radon test performed.
