 PFAS in Water Filtration Solutions

PFAS are a group of man-made chemicals that have been manufactured and used in a variety of industries since the 1940s. Some of the more common commercial applications have been for products like Teflon, stain & waterresistant materials, paints, polishes, fire fighting foams (a major source of ground water pollution near airports, military bases and fire fighting training centers). These chemicals are being detected at dangerous levels in drinking water supplies around the country. (For removal from water, see section below, “REMOVAL OF PFAS”).

PFOA and PFOS have been the most extensively produced and studied of these chemicals.  Both chemicals do not break down and they can accumulate over time. There is evidence that repeated exposure can lead to adverse human health effects. As a result, these chemicals are no longer manufactured in the United States, but are still made in other countries and may be contained in products imported into the U.S.

There is evidence that exposure to PFAS can lead to adverse health outcomes in humans. If humans or animals ingest it (by eating or drinking food or water), they are absorbed and can accumulate in the body and can stay in the human body for long periods of time. As a result, as people get exposed from different sources over time, the level in their bodies may increase to the point where they suffer from adverse health effects.

Studies indicate that PFOA and PFOS can cause reproductive and developmental, liver and kidney, and immunological effects in laboratory animals. Both chemicals have caused tumors in animal studies. The most consistent findings from human epidemiology studies are increased cholesterol levels among exposed populations, with more limited findings related to infant birth weights and:

• effects on the immune system,
• cancer (for PFOA), and
• thyroid hormone disruption (for PFOS).

PFAS Removal System

There are technologies effective in removing PFAS from drinking water, especially Perfluorooctanoic acid (PFOA) and Perfluorooctanesulfonic acid (PFOS), which are the most studied of these chemicals. The most effective technologies include Ion exchange, activated carbon adsorption and reverse osmosis. For more information on removal, see

Reverse Osmosis System

Reverse Osmosis, Point of Use System To Remove PFAS

This membrane based technology can be installed at a point-of-use such as a separate faucet at a kitchen sink, or installed in the basement below running a line up to the faucet. Highly effective at removing PFAS from drinking water. See http://reverse-osmosis-water-purification.
