Addressing Emerging Contaminants in Drinking Water

Addressing Emerging Contaminants in Drinking Water

Managers of drinking water sources across the country are finding emerging contaminants such as perfluoroalkyl substances (PFASs) including perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) above USEPA and individual state health advisory levels. Sources of PFASs include industrial and commercial products such as nonstick cookware, non-stain fabrics, water repellent coatings, fast-food packaging and firefighting foams. These contaminants are highly stable, environmentally persistent and pose a risk for potential adverse health effects.

Weston & Sampson has experience assessing and remediating PFASs in drinking water in many locations, with projects including:

  • Seasonal surface water assessment and remediation of PFASs upstream of municipal drinking water intakes. PFASs were released into a river during the response to a civilian aircraft crash where there was an application of fire-fighting foam.
  • Environmental services to address municipal drinking water supply wells impacted by PFASs, including carbon treatment.
  • Evaluation of private drinking water wells impacted by PFASs. To date, over 250 private water supply wells have been sampled for PFASs in areas near specialty fabrics and wire coating industrial facilities.

If you would like assistance with your evaluation or treatment of PFASs, please contact Blake Martin, VP, at 978.977.0110 x2290, or
