wells on the Chemours property in early August. Concentrations ofGenX were detected in|3ofl4
industrial wells at the plant exceeding the 10 parts per trillion practical quantitation limit, which is a state
regulatory limit used for chemicals when no rstandard has been established, such aaGon}{.
Two wells on Chemours' property also revealed exceedences of the state's interim groundwater standard
for PF0/\of 2,000 parts per trillion. Preliminary test results have identified other detections of flouninated
compounds.
The groundwater regulatory standards for GonXand the other fluorinated compounds are different from
drinking water health goals established by the N.C. Departnient ofHealth and Human Services and the
Environmental Protection Agency' Drinking Water Health Advisory level, 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 are still awaiting results of testing done on the same wells and sent to the
Environmental Protection Agency's lab in Research Triangle Park. Those results are expected soon.
Additionally, Chemours engaged Test America in Colorado to perform a similar analysis, but they have
yet to share their results with the State.
