Hazardous Sites near Arlington, TX

There are two Superfund sites in Tarrant County, TX. Superfund sites, like Sandy Beach Road Ground Water Plume in Pelican Bay, TX, 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.

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 Tarrant County, TX as follows:

Ozone Pollution

Radon Levels in Arlington, TX 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 Tarrant County, TX is predicted to be less than 2 picocuries per liter (pCi/L), so the county has been assigned EPA Radon Zone 3.

EPA Radon Zone

But, it's worth mentioning homes with elevated levels of radon have been found in all three radon zones. So, despite the fact Arlington, TX is in EPA Radon Zone 3, you should have a radon test performed on any home you purchase in the area.
