Recent test results of GenX found in the Cape Fear River at outfall 002 indicate there is a general trend
downwards in concentrations, though there is a continual discharge. Values of GenX seen in finished
water at water treatment plants downstream of the Chemours facilities are also seeing a general trend
downward but each sampling round has seen a test result above the current DHHS health risk goal of
140 ppt. We are expected to see EPA National Exposure Research Lab test results for other GenX
related compounds from the Chemours wastewater discharge and sampling conducted at water utilities
above and below the discharge point later in August, 2017. Those results will assist the state in setting
NPDES parameters for a draft renewal permit. Having access to the CBI material for all the
manufacturing at the facility will ensure we have address all chemicals of concern in the permitting
