*PFOS and PFOA levels show potential to cause the downstream water supply intake to exceed the EPA drinking water health advisory concentration of 70 ng/L. Sanford’s Water Treatment Plant intake is the water supply intake that

could be affected by the wastewater treatment plant's discharge. DEQ will discuss additional sampling and source identification measures with the City of Sanford.
