Exposure to PFAS through drinking water is a global human-health concern. The ability of PFAS to resist degradation in the environment has led to their accumulation in water sources over time. Once these chemicals enter the water supply, they can be consumed by humans, leading to potential health risks. Studies have linked PFAS exposure to adverse health effects, including developmental issues, immune system dysfunction, and even certain types of cancer.
PFASs have been used for decades in the manufacture of ordinary household products like cleaning supplies, fingernail polish, and pesticides. Industries that relied on them included electronics, construction, and aerospace as well as the military. They have also been used in the production of firefighting foam used to extinguish petroleum-based fires at refineries, airports, and chemical manufacturing plants.
