What are PFAS and why are they suddenly in the news? PFAS in drinking water pose serious long term health problems. Yet they are just now being discovered in water systems throughout the US. PFAS are just one of a group of chemical compounds causing grave health concerns.

Per- and polyfluoroalkyl substances (PFAS) are a group of man-made chemicals that includes PFOA, PFOS and GenX chemicals. Since the 1940s, PFAS have been manufactured and used in a variety of industries around the globe, including in the United States. – USEPA

Read this EPA document for a detailed description of these chemicals and they’re health effects. Here’s an excerpt from the following article: “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 animals.”

Recently CNN posted the following articles on PFAS in numerous cities in southern California. Because of the long term health effects this is an issue to take seriously. Therefore learn what you can to remove them from the water entering your home.  But first check, if you live in California, out these two links.

CNN article on PFAs in California drinking water:

The Environmental Working Group did the research of existing local water quality reports. That lead them to develop this list of California cities where PFAs have been found in the water:

This problem is not restricted to California.

Cities around the country have PFAS in drinking water. Therefore, the action to take wherever you live is to check your local water quality report. This report is provided every year by your water supplier. It lists the regulated contaminants in your water. These reports are beginning to address the issue of PFAS and their associated compounds. You can often find these reports online. See this map by Environmental Working Group of the US showing PFA and PFOA locations:

Sadly, one of the manufacturers determined early on that they were contaminating the US food supply with PFAS:

The following list shows the level of contamination is selected cities around the US:

Cities with excessive levels of PFAs and PFOAs

Removing PFAS from Drinking Water

If you live in a location where these contaminants are in your drinking water take action now. Whole house carbon filters will reduce the level of PFAS in water. A reverse osmosis system at the kitchen sink can eliminate them. Thus preventing you from ingesting them. Again, before you overreact be sure to confirm that PFAS are in your water.  Take these steps:

Look at the map above

Contact your water provider and ask for a water quality report

If they PFAs or PFOAs are present take immediate steps to stop drinking them.

Add Sweetwater’s custom reverse osmosis system to protect yourself.
