PFAS compounds are often called “forever chemicals” because these perfluorinated compounds have a particular affinity for water, so they are difficult to remediate. In fact, the CDC reports that the majority of Americans have been exposed to PFAS contamination. The PFAS health effects are not well understood, but scientific research suggests that exposure to PFAS may lead to reproductive effects, developmental effects, increased risk of some cancers, comprised immune responses, interference with hormonal production, and increased levels of cholesterol and/or obesity. It is challenging to identify the health effects of each PFAS compound, so data-driven regulations lag behind the environmental and human health risks of these contaminants.
