Treating PFAS Contamination in Groundwater

You’ve certainly heard the growing concern about PFAS in the state’s drinking water. PFAS, or per- and polyfluoroalkyl substances, are a class of long-lasting chemicals that have raised significant health and environmental concerns in recent years.

Here’s what you need to know:

Widespread Use

PFAS are found in many consumer, commercial, and industrial products. They are used in fabrics, carpeting, and other items with stain- and grease-proof coatings. Due to their persistence in the environment, PFAS are present in water, air, fish, soil, and even our blood.

Health Risks

Scientific studies have linked exposure to some PFAS to harmful health effects in both humans and animals. These effects include:

  • High Blood Pressure
  • Elevated Cholesterol Levels
  • Kidney and Testicular Cancer
  • Impaired Vaccine Response
  • Liver Dysfunction
  • Blood Pressure Changes
  • Increased Cancer Risk

Forever Chemicals

PFAS are often referred to as “forever chemicals” because they break down very slowly over time. Their persistence makes them challenging to manage.

Although studies generally show a low risk of PFAS in groundwater, wells near areas where PFAS were historically used—like airports, fire training zones, landfills, manufacturing hubs, and biosolid application sites—face higher susceptibility.

At U.S. Water, we offer a wide range of home water filtration solutions to suit your specific needs:

Whole-House Filtration: Install a comprehensive system that filters all the water entering your home. Say goodbye to contaminants in your drinking water, bathing water, and even the water you use for laundry and dishes.

Under-Sink Filtration: Enjoy purified water directly from your kitchen faucet. Our under-sink systems are convenient, space-saving, and highly effective.

Defending Your Water: Comprehensive PFAS Water Testing and Treatment Solutions

Given the intricate nature of PFAS testing requiring specialized instruments and methods, the cost for testing is higher than for most other contaminants. Collecting the water sample demands careful adherence to detailed instructions and the use of specialized containers provided by the laboratory.

Combatting PFAS with Home Treatment Systems

Numerous water treatment devices effectively purge PFAS from water sources. Since consuming water is the primary source of PFAS exposure, installing small point-of-use (POU) treatment systems on a single faucet can significantly diminish PFAS intake. These systems—such as reverse osmosis (RO) and granular carbon filtration (GAC)—prove to be efficient solutions.

For broader protection, larger point-of-entry (POE) water treatment systems serve the entire household’s water supply. These encompass anion exchange units (similar to water softeners), larger GAC filters, or whole-house RO units.

Water Filtration Solutions:


Reverse Osmosis

For a cost-effective, under-the-sink treatment system, reverse osmosis systems are highly effective in filtering out PFAS and a wide variety of other contaminants. 


Ion Exchange Resins

These resins can selectively remove PFAS from water by exchanging ions. They are effective for removing both PFOA and PFOS for an entire home or business.

Activated Carbon Treatment

Activated carbon provides a large surface area for contaminants like PFAS to adsorb. Systems can effectively treat the entire home.

FAQs on PFAS Testing

DIY test strips DO NOT accurately detect PFAS. Specialized equipment is necessary for precise detection due to the chemicals’ sensitivity.

In addition, some substances in water can interfere with PFAS detection. 

While at-home sample kits are available, the accuracy of these may vary widely depending on the sample collecting circumstances and other substances in your water.

For the most reliable results, utilize a state-certified laboratory using EPA-approved testing methods. Certified labs remain the gold standard for accurate PFAS level assessment in drinking water.

Be sure to flush pipes before sampling in order to remove stagnant water.

Avoid overfilling containers.

Use clean, uncontaminated containers provided by the testing company to prevent any alterations in results.
