Not necessarily. The MassDEP PFAS6 MCL and USEPA lifetime health advisories are set to overestimate potential exposures. Their goal is to make sure that sensitive populations, like infants and pregnant or breastfeeding mothers, are protected. The advisories also take into account differences between animals and humans, and differences between humans. As stated by MassDEP, “a risk would be expected only if an individual continuously drinks only contaminated water at a level significantly higher than the MCL.” The best way to reduce the potential health risks is to limit your exposure as much as possible (more info in FAQs #20, #23, and #28).
