80-plus years of indiscriminate forever chemical (PFAS) dumping has caused them to accumulate in the environment where they ultimately migrate to both surface and groundwater sources. Once in the water reservoirs, they increase in concentration, driven by continued migration from the sources. When ingested by humans, PFAS bioaccumulate in the body ultimately causing several health problems. It is estimated that over 100 million people in the U.S. have ingested forever chemicals in their drinking water. Over time the contaminants reach or exceed dangerous levels in their bodies.
The current EPA health advisory limit (HAL) requires potable water to contain total PFAS at less than 70 parts per trillion (ppt). For perspective, one part per trillion is equivalent to 1 droplet of water in 20 Olympic-sized swimming pools.
