June 14, 2017: The North Carolina departments of Environmental Quality (DEQ) and Health and Human
Services (DHHS) investigate the presence of a compound known as GenX in the Cape Fear River.
Chemours was identified as company that produces the chemical for industrial processes at its facility in
Fayetteville. DEQ strongly encouraged Chemours to identify any measures that can be taken to reduce
or eliminate the discharges of the chemical to the river until the state completes its investigation.
June 19: DEQ began collecting water samples from 12 sites along the Cape Fear River, with additional
samples collected throughout the region in the following weeks. After meeting with DEQ staff,
[hemoursagreed topay for the sampling and analysis.
* The analysis of water samples will be conducted by two independent laboratories, aoertUUed
facility in Colorado and a U.S. Environmental Protection Agency laboratory in the Research
Triangle Park near Raleigh.
Aug. I — 10: DEQ`s Division of Waste Management Hazardous Waste Branch staff collected groundwater
samples from 14 monitoring wells on the Chemours property. The EPA and Chemours also collected
separate samples from the same monitoring wells.
Aug. 28: EPA scientists told the state that they have identified two compounds they are calling Nafion
byproducts I and 2 in Chemours' waste stream and that estimated concentrations of these compounds
are not decreasing.
Aug. 29: DEQ ordered Chemours to stop discharging into the Cape Fear River those two additional
chemical compounds identified bythe EPA.
Aug. 29: DEQ wrote Chemours asking the company to stop the release of the two compounds. DEQ also
repeated its call for Chemours to provide the state agency with a complete inventory, sampling data and
test results for all chemicals included inthe company's waste stream.
Aug. 31: Details on the EPA's findings are included in a report shared by the federal agency with DE[\
Sept. S: State officials ordered [hemounto stop releasing all fluorinated compounds into the Cape Fear

discharge of all fluorinated compounds and disclose everything in its waste stream.
Sept. 5: DEQ received results from the its groundwater monitoring well samples collected in early
August. These results showed concentrations of GenX were detected in 13 of 14 industrial wells at the
plant exceeding acceptable limits. These preliminary test results also identified other detections of
f|ourinatedcompounds.

Sept. 6: State officials initiated additional enforcement actions against Chemours Wednesday after
preliminary state test results detected GenX in violation ofstate groundwater standards in non -drinking
water wells at the company's Fayetteville Works facility.
Sept. 6: DEQ cited Chemours with a notice of violation — one day after the state initiated other legal
action against the company.
Sept. 6: DEQ announced plans to sample residents' drinking water wells who live adjacent to the
[hemoursfaci|ky.
Sept. 14:DE[\and DHHShold apublic information session toanswer residents' questions about
upcoming private well sampling, allow residents to sign up to have their private wells tested and provide
health -related information regarding GenXand other legacy compounds.
Sept. 15: DEQ!s Division of Waste Management staff will begin sampling residents' drinking water wells
who live near the Chemoursfacility.
