"... we strongly urge EPA to consider altering its regulatory approach to regulate PFAS at the source, placing the burden of proof that the products are safe for consumers and the environment on those who manufacture and utilize PFAS products before they are manufactured."

Frequently Asked Questions

PFAS: What are they?

PFAS, often referred to as forever chemicals are a group of thousands of manmade compounds – called per- and polyfluoroalkyl substances – that have been in use since the 1940s in common household and commercial products.  

They are resistant to heat, stains, and water making them popular additions to cookware, clothing, carpets, cosmetics, and furniture.  PFAS are also found in millions of other goods, including products you may have never imagined like dental floss, cake mix, cardboard straws, and toilet paper. The EPA estimates that 80% of a person’s exposure is from consumer products.  

PFAS not only enters the environment through consumer use and disposal, but also through surface and groundwater contamination.  For example, PFAS proved to be an essential addition to firefighting foam.  Unfortunately, for many communities near airbases and airports, the washing down of the foam after training exercises led to surface and groundwater contamination.

PFAS: How do these manmade compounds end up in drinking water?

Our water filtration plants do not produce or use PFAS.  However, PFAS can end up in source water and then drinking water due to continued manufacturing and use of PFAS-laden products.

For example, PFAS are still used with nonstick cookware. Scraping and washing a nonstick pan with PFAS discharges the compounds into our wastewater system.

Because of their resistant properties, PFAS can move through the conventional water treatment processes largely intact.

PFAS: What is WSSC Water doing to supply safe, clean drinking water to customers?

WSSC Water’s mission is to protect public health and safety by supplying safe, clean and reliable water to our 1.9 million customers.  We are proud of our nearly 105-year history of zero drinking water quality violations and remain committed to continuing this exceptional level of excellence.  

When the EPA’s proposed drinking water standards are finalized later this year or in 2024, WSSC Water will evaluate the final standards to determine if treatment process changes are necessary.  

For several years, WSSC Water has been proactively testing for PFAS compounds in our drinking water, testing that went above and beyond federal and state requirements.  WSSC Water monitors for 29 PFAS compounds that are included under the EPA’s Fifth Unregulated Contaminant Monitoring Rule, also known as UCMR5.  We will continue to transparently post our results as we conduct our tests.  You can view our PFAS test results here. PFAS Test Results

UMCR 5 testing is intended to give the EPA and water providers a greater understanding of how pervasive PFAS are in our nation’s drinking water.  WSSC Water will review our UCMR5 test results to determine if additional courses of action are necessary.  

PFAS: How to limit PFAS exposure?

Avoid buying non-stick cookware and stain-resistant furniture and carpeting containing PFAS. Look for ‘fluoro’ or ‘perfluoro’ in a list of ingredients or ask the manufacturer.  

Limit eating foods packed in materials that use PFAS, like microwave popcorn bags, fast food boxes and bakery bags.  

And avoid personal care products with PFAS, including certain dental floss, nail polish, facial moisturizers and cosmetics. Limiting the use of products containing PFAS will help protect drinking water supplies.
