'We are taking all necessary steps to address clear violations of state rules and will launch a private well
testingregimen for homeowners living near the facility who wish Vohave their wells tested for free, to
determine ifthe contamination has moved beyond the facility into well water used for
dninking," said Michael Regan, secretary ofthe N.C. Department ofEnvironmental Quality."As ioour
routine when we find violations of groundwaterrules onucompany's property, we are reaching out to
residents who use wells as their source of drinking water."
Preliminary Test Results from Chemwnrs^Wells
/\opart ofthe ongoinginvestigation, N.C. [)BU collected groundwateroomp|oo from 14groundnxatur
monitoring wells on the Chemours property in early August. Concentrations of GenX were detected in 13
of 14 industrial wells at the plant exceeding the 10 parts per trillion practical quantitation limit, which is a
state groundwater regulatory I ]in it used for chemicals when no groundwater standard has been
established, such ao(}onX. Two wells on Chonooury` property also revealed levels above the otatu`e
interim groundwater standard for PFOA of 2,000 parts per trillion. Preliminary test results have identified
other detections of flouhnatodoonupoondo.
The groundwater regulatory standards for GcnXand the other fluorinated compounds are different from
health goals for drinking water established hvthe N.[.Department ofHealth and Human Services and the
Environmental Protection Agency' Drinking Water Health Advisory |croi which are used for public
health, not regulatory reasons.

The water samples collected by DEQ in early August at the company's industrial wells were sent to three
laboratories. The preliminary results come from only one of the labs — Gel Laboratories in Charleston,
S.C. State officials have not received test results from Chemours that were sent to Test America's
Colorado lab for analysis, and are awaiting final results from the EPA lab in Research Triangle Park.
