How does PFAS get into drinking water?
PFAS enter drinking water when they migrate from soil to groundwater or surface. PFAS is water-soluble and is usually found in water near facilities that produce or use PFAS and products containing PFAS. Also, many contaminated areas are near facilities that use PFAS fire fighting foam for training, such as B. military bases, airports, and firefighter training centers.
Finally, PFAS may enter the water when products containing PFAS are disposed of in landfills. When the product decomposes, PFAS is retained in the soil and flows to nearby water sources.
70 parts per trillion (ppt) is the maximum safe level of PFAS in drinking water, according to the Environmental Protection Agency (EPA). 70 parts per trillion is the health guidelines set by the EPA. While inaccurate, the health council aims to educate public health officials and government agencies and provide people with protection from PFAS exposure through drinking water.

What are the health effects of PFAS?
The health effects of PFAS vary, but include reproductive, developmental, and immunological problems. Since PFAS is not easily degraded and can accumulate excessively in the human body, the greater the exposure to humans, the greater the chance of adverse health effects. The EPA cites evidence linking PFAS exposure to:
- High cholesterol levels
- Suppressed immune system
- Thyroid hormone disorders
- Damage to the liver and kidneys
- Low birth weight
How do you know if your water is dirty?
You can find out if your water is contaminated by requesting a city water quality report or by testing your water. Municipal water suppliers frequently check the water supply and are legally required to hand it over to you if you request it.
