RALEXGH—Stoteoffiobdobndkatododddkonal enforcement actionsagainst Chen/our Wednesday after
preliminary state test results detected GenXand another perflouninated compound in violation of state
groundwater standards innon water wells u1the company'sFayetteville Works facility.
Preliminary test results publicized today hvthe state Department ofEnvironmental Quality show
concentrations ofGeoXand PF0/\iuwells onChomnuraFayetteville Works' property inviolation of
state groundwater standards. The wells tested are used forenvironmental monitoring at the facility and are
not a source of drinking water.
Based onthe preliminary results, DE0announced its plans &xcite Chemour with onotice ofviolation
and a notice of intent to enforce. Today's announcement comes a day after the state initiated o-ther legal
actioll
against the company.
DGOand the N.C. DepartmentofHealth and Human Services onWednesday also alerted health offiubzo
in8kadonand Cumberland counties tothe preliminary test results and started plans totest private
water wells near the Chonuourufacility.
The two state agencies are plans Vohost umeeting soon intheFayetteville area toanswer peoples'
questions about the groundwater test results. Details of the meeting will be made public soon.

said Michael Regan, secretary ofthe N.C. Department ofEnvironmental 0uu|"As is our routine when
we find violations of groundwater rules on a company's property, we are reaching out to residents who
use wells as their source of drinking water."
Preliminary Test Results from Cheo/oumy~ Wells
Aspart ofthe investigation, N.C. DRO collected groundwater samples from 14 groundwater monitoring
wells mothe Chomour property inearly August. Concentrations of[enXwere detected in|]of|4
industdo]wells o1the plant exceeding the |0parts per trillion practical quondtobonlimit, which ioostate
regulatory limit used for chemicals when no groundwaterstandard has been established, such amGen}{.
Two wells on Chemours' property also revealed exceedences of the state's interim groundwater standard
for PFOA of 2,000 parts per trillion. Preliminary test results have identified other detections of flourinated
compounds.
The regulatory standards for GeoXand the other fluorinated compounds are different from health goals
established hvthe NI. Department ofHealth and Human Services and theEnvironmental Protection
Agency' Drinking Water Health Advisory level, which are used for public health, not regulatory reasons.
The water samples collected bvDEQ in early atthe company's industrial wells were sent tothree
laboratories. The preliminary results come from only one of the labm—Gel Laboratories inCharleston,
S.C. State officials are still awaitim4 results of testing done on the same wells and sent to the

Environmental Protection Agency's lab in Research Triangle Park and Test America in Colorado. State
officials expect those results soon.
Private well sampling plans
Staff with DEQ and DHHS today will travel to homes surrounding the facility and seek permission to test
the private drinking wells of homeowners' who live nearest Chemours' industrial wells tested. DEQ staff
consulted GIS data and worked with local officials in Cumberland and Bladen counties to identify well
users living near the facility.
The state will answer questions from homeowners with private wells and provide those residents with
public health fact sheets and other information about the state's investigation, the testing and the
compounds.
DEQ and DHHS plan to sample private wells for GenX as well as other chemical compounds identified in
a 2016 report by the EPA and N.C. State University that identified the compounds in the Cape Fear River.
Other groundwater
Based on the state's investigation, DEQ and DHHS officials say there is not scientific evidence based on
water sampling the state has already conducted of any signs GenX in any private drinking wells at any of
the multiple sites on the Cape Fear River where the state has been conducting testing downstream from
the Chemours facility.
