GenX & PFBS
The health advisory levels were calculated for the most sensitive populations, e.g., infants. If the GenX or PFBS is below the advisory level, then it is not expected to increase risk of health effects and can be used.
PFOA & PFOS
The new EPA health advisory levels for PFOA and PFOS are below levels that can be detected with current commercial laboratory testing. Therefore, any detection of either PFOA or PFOS in drinking water could represent an increased health risk and we would recommend using an alternate source or filtered water.
