Per- and Polyfluoroalkyl Substances (PFAS)
What are per – and polyfluoroalkyl substances (PFAS)?
Per – and polyfluoroalkyl substances (PFAS) are a group of manmade chemicals that have been used worldwide, including in the United States, in consumer products, industrial applications and in firefighting since the 1940s. There are between 6,000 and 10,000 different chemical compounds in the PFAS family and they are used to make products that resist heat, oil, stains, grease and water.
What is Stafford County Doing?
In 2013 Stafford County conducted testing as part of the Environmental Protection Agency’s (EPA) Unregulated Contaminant Monitoring Rule 3. All results were non-detect, meaning that all results were below the reporting level. The analysis was conducted using EPA Method 537.
In April 2021, the Virginia Department of Health (VDH) requested that Stafford County, along with several other Virginia waterworks, participate in a Virginia PFAS Sampling Study. Results from VDH's Sampling Study were received in June 2021 and can be found here: Stafford County PFAS Sampling Study Results
What can I do?
- Cook at home. Home-cooked meals are often more nutritious, and the fresher your food is, the less likely it will be to have been exposed to packaging that may contain PFAS or other concerning chemicals.
- Check your cookware. Cook with stainless steel, cast-iron, glass, or ceramics. Avoid nonstick cookware.
- Read consumer product labels on cleaning products, cosmetics and other personal care products. Choose products without PTFE or perfluoro- or polyfluoroalkyl substances.
- Avoid stain or water-resistant carpets and upholstery; decline stain treatment.
- Avoid using grease-resistant paper, fast food containers/wrappers, microwave popcorn bags, pizza boxes, and sliced cheese wrappers
Are PFAS regulated?
Virginia does not have a regulatory standard at this time.
PFAS were included in the EPA’s Third Unregulated Contaminant Monitoring Rule testing in order to determine how prevalent certain perfluorinated compounds are in U.S. drinking water supplies and at what level they appear.
To provide Americans, including the most sensitive populations, with protection from a lifetime of exposure to PFOA and PFOS from drinking water, the EPA released health advisories for perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS), making a lifetime health advisory for each compound, or a sum total of the two, of 0.07 parts per billion.
