PFAS end up in drinking water when they travel from soil to groundwater or the surface. Because PFAS is water-soluble, it is frequently found in water near facilities that make or use PFAS, as well as commodities containing PFAS.
Furthermore, many polluted areas are near training facilities that use PFAS firefighting foam, such as military bases, airports, and firefighter training centers. Finally, PFAS may enter groundwater when PFAS-containing goods are disposed of away in landfills. When PFAS decomposes, it remains in the soil and runs into nearby water sources.
The highest allowable quantity of PFAS in consumable water, according to the Environmental Protection Agency, is 70 parts per trillion (ppt) (EPA). The Environmental Protection Agency has established health guidelines of 70 parts per trillion. While erroneous, the health council's purpose is to educate public health specialists and government institutions about PFAS exposure through drinking water.

What are the health consequences of PFAS?
The health effects of PFAS vary but may include reproductive, developmental, and immunological problems. Because PFAS is not easily removed and can accumulate excessively in the human body, the greater the danger of negative health effects, the greater the risk of human exposure. PFAS exposure, according to the EPA, has been associated to:
High cholesterol levels
Suppression of the immune system
Thyroid hormone deficiencies
Damage to the liver and kidneys
The birth weight is insufficient.
