Why are PFAS a concern for drinking water?

Due to their widespread use, mobility, and tendency to persist for long periods of time, PFAS can often be detected at low ambient levels in the environment. In places where PFAS have actually contaminated water supplies, such contamination is typically localized and associated with a specific facility, for example, at airports and military bases where firefighting training occurs or an industrial facility where PFAS were produced or used to manufacture other products.

Unfortunately, some communities around the country have experienced levels of PFOA or PFOS in their water that exceed the EPA health advisory level of 0.07 parts per billion (ppb). Springfield does not have any known sources of PFAS contamination. Nevertheless, given PFAS’ emergence as a contaminant of concern for groundwater, SUB has opted to voluntarily sample its well water to ensure a safe water supply.
