PFAS are a large family of human-made chemicals. The backbone of all PFAS molecules is the carbon (C) and fluorine (F) chain. The C–F bond is very strong, making these molecules nearly unbreakable. PFAS are known as “forever chemicals” because they persist and accumulate over time.
Manufacturers use PFAS to create “slippery” surfaces and products that resist water, heat, and grease. This is why they have been useful in products like non-stick cookware, fire-fighting foam, stain and water repellants, and food packaging. Because of the prolific use of PFAS since the mid-1900s, the chemicals are found essentially everywhere including in the environment and the human body.
While scientists are still learning about the impacts of PFAS on human health, some studies have shown that exposure to PFAS may have adverse health effects. The primary sources of exposure are thought to be food and food packaging, furniture, carpeting, clothing, and drinking water.
How can WLSSD help with PFAS pollution prevention?
WLSSD and other wastewater treatment plants have unique access to a community’s wastewater; this access can provide for some interesting scientific “sleuthing” by testing wastewater components. For example, WLSSD has done some detective work with mercury in wastewater to identify sources and to reduce mercury pollution. WLSSD also collaborated with the U of MN to measure the presence of the coronavirus in our community by monitoring it in wastewater. In the same spirit of scientific investigation, WLSSD will measure PFAS in our community’s wastewater as a way to identify and reduce sources of PFAS through pollution prevention strategies. WLSSD is also committed to providing PFAS education and pollution prevention programming to residents in the communities we serve.
What can we all do to reduce PFAS pollution and exposure?
The United States has made progress to reduce manufacturing and distribution of PFAS-containing products, and we can go a step further in limiting our exposure by making informed consumer choices. To reduce exposure to PFAS and prevent pollution in the environment, consider the following action steps:
