The EPA has released official long- term exposure guidelines for PFOA, PFOS contamination.

Released documents state that concentrations of PFOA and PFOS below 70 parts per trillion is not expected to result in adverse health effects over a lifetime of exposure.

Vermont lists safe exposure levels at 20 parts per trillion, including babies and children.

Regional EPA originally set short term exposure as 100 ppt in Hoosick Falls.


'EPA's assessment indicates that drinking water with individual or combined concentrations of PFOA and PFOS below 70 parts per trillion is not expected to result in adverse health effects over a lifetime of exposure. These levels reflect a margin of protection, including for the most sensitive populations. " , says the EPA in a released document.
