New data shows the persistence of forever chemicals in Delaware’s surface waters.
A study conducted across 33 watersheds in the fall of 2022 looked at the extent of per- and poly-fluoroalkyl substances, colloquially known as “forever chemicals” due to their perceived inability to degrade over time.
Many different methods were performed, looking at dozens of chemicals that fall under the PFAS family, and six watersheds were identified as having prioritized concentration for future testing.
Here’s what to know.
What are forever chemicals?
PFAS, which stands for per- and poly-fluoroalkyl substances, are a class of chemicals that have been used in a wide variety of manufacturing processes over the years that potentially cause adverse health impacts upon consumption. Due to their longevity in the environment, they often are referred to as forever chemicals.
Commonly known sources of forever chemicals include firefighting foams, wire insulation, cleaners, textiles and other consumer products.
