In February of 2019, the EPA released an “Action Plan” on how they will be addressing the “forever” chemicals known as PFAS.

PFAS, or “Per and Polyflouroalkyl Substances,” are found in the food we eat, products we use, and even the water we drink. Recently in Connecticut, the potential health risks of PFAS were brought to light when large amounts of Firefighting Foam made their way into the Farmington River after it was used to put out an aircraft fire at Bradley Airport.

This raised concern about how local wells could be impacted with the runoff of the foam containing these chemicals.

The EPA lists several way approved to remove specific PFAS from drinking water:

Granular Activated Carbon (GAC)

  • GAC was found to be very effective at removing PFAS from drinking water
  • GAC tanks are easy to install and require no backwashing
  • Require yearly media replacement*
  • Also effective at removing Radon and some odors

Anion Resin

  • Similar to a water softener in form and function
  • Requires regeneration and discharges wastewater
  • Requires a brine tank and salt maintenance
  • May require other equipment for pre-treatment of water in order to be effective
  • Requires specific Anion Resin for perchlorate removal

Reverse Osmosis

  • Found to be very effective at removing PFAS from drinking water
  • Point of use system (usually kitchen sink)
  • Easy to install
  • Requires yearly filter changes*

The first step is to have your water tested for PFAS to see if you are at risk. The results will help determine which system would be best for you and your family. Call us for details about water testing and treatment options.
