Hi Mr. Burdette,
l,nn attaching intonnation about the updated risk assessment. This was just sent out along with the release below
detailing recent Gcn}Csampling results. lthink this document answers the questions from your original emoil.
l`nn sorry for the delay; this is o complicated process as } know you're aware. Our goal has been to have this
information ready when vvcreceived the results from [}B(), which happened this morning.

Information for GenXin Cape Fear River I
RALEIGH — State officials today released their first results of water quality samples and an updated preliminary
health assessment for concentrations of the unregulated compound GenX in finished, or treated, drinking water.
The revised health goal for exposure to GenX in drinking water is 140 nanograms per liter (also referred to as parts
per trillion).
Samples were analyzed at the U.S. Environmental Protection Agency lab in Research Triangle Park and at ­-:­---.-.------,-.'.
olab inColorado under contract toChennouna.
Data from samples collected June 19 and July 6 show that the most recent results of finished, or treated, water in all
but one facility were below the N.C. Department of Health and Human Services' health goal of 140 parts per trillion.
The data also reveal that concentrations ofGenXare trending downward.
Although no information is available about recreational health risks, people should refrain from swimming near the
Chemours facility.
"Our goal, isto protect the safety and health of all North Carolinians," said Mandy Cohen, secretary of the N.C.
Environmental Quality to understand and communicate information in a timely manner, to help those impacted."

W.C. Department ofEnvironmental Quality Secretary Michael Regan said:
"Safe drinking water is n top priority for this administration, and QEQ takes aehoua!v its responsibility to protect the
health and welfare of the public. We will continue to investigate this issue and make new information available to the
public in a timely fashion."
The findings reflect water quality data from snnlphea collected in the Fayetteville and Wilmington areas
between June 19 -July 6. Results show higher concentrations near the point where Chemours' Fayetteville
manufacturing facility was discharging GenX into the Cape Fear River, and much lower concentrations at the public
water supply systems near the facility and 70 miles downstream in the Wilmington area
The W.C. Department ofHealth and Human Services released an initial preliminary health risk assessment on June
8 for GenX in the Cape Fear River. Based on continuing analysis of health data and consultation with the
Environmental Protection Agency, the N.C. Department ofHealth and Human Services today updated its initial
preliminary health assessment for GenX, the unregulated chemical compound recently identified in the lower Cape
Fear River.
Lower second week values reflect reduced exposure to GenXvvhen, at the urging of state, |oon| officials and
concerned citizens, ChennouraonJune 21 began diverting wastewater containing the contaminant into storage tanks
to be shipped out of state for incineration. DEQ inspected the Chemours site again this week after the company
indicated that data it had collected was higher than what it would have expected to see after the June 21 vvaobevvabsr
diversion had started. QEQ inspectors confirmed this week that Chernours stopped the additional discharges of
GenX into the river and is collecting them for removal and incineration.
The following data table reflects partial results of concentrations of GenX after the water had been treated by public
water systems.

Early results from all 13 test sites can be found on the N.C. Department of Environmental Quality's GeisX
website:

A document showing the results in a spreadsheet is
at:
.................................................................. ....................... : ........... . ................................................................. . .................................... . ........
Additional water sample testing and analysis are underway with results to be shared once analysis is completed.
The state's preliminary health goal was developed in consultation with EPA and the Centers for Disease Control and
Prevention. Ongoing discussions will apply guidance from leading federal researchers of emerging contaminants to
help state officials provide the public with the best information available on potential health risks posed by GenX.
Officials have been collecting water samples at multiple locations in the Fayetteville and Wilmington areas each
week since June 19 and will continue sampling until at least late July. DEQ officials have extended the state's
sampling regimen from three -to -six weeks to provide a more comprehensive understanding of Gen X concentrations
in the lower Cape Fear River.

Thanks for reaching out and for asking these follow-up questions. Itwas apleasure meeting you as
well and toshare time onthe panel together.
I'm copying two of my fellow teammates in our Division of Public Health (DPH) that were very involved
inthe developing our health advisory, including the levels. They are Mina Shehee and Zack Moore and
one of them will follow-up directly with you.
Thanks, again, for your email ... and, more importantly, for your work to protect the Lower Cape Fear
River.

My best,

Subject: Cape Fear GenX
DEQ-CFW-00082708

Dear Mr. Benton,
It was a pleasure to meet you at the GenX forum in Wilmington and to sit on the panel with you to
discuss this emerging and extremely important issue. As you can imagine the approximately 300,000
people of the Lower Cape Fear Region who drink water from the Cape Fear River below the
DuPont/Chemours discharge are extremely alarmed about the very real threat to our drinking water
supply.
As the Cape Fear Riverkeeper, I represent over a thousand members who value clean water and believe
that it is a universal right. In response to the GenX issue, literally tens of thousands of local residents
have joined numerous Fac*bnoh groups. |istsorves. neighborhood Qroups, mother's groups. etc. We
have had three community forums, each well attended by concerned citizens, community leaders,
elected officials, and the media (including numerous national outlets). There is one striking aspect to
every interaction I have observed surrounding this issue; people have questions which they do not feel
are being adequately answered.
As a representative of thousands of people in our community, I am writing today to request that you
share the methods you used to make the determination that the levels of GenX in the Cape Fear River
drinking water are "low risk" There isugrowing consensus among scientists, community leaders and
environmental activists that 70,909 ppt of GenX in drinking water does in fact pose significant risk to
human health.
In particular, we request you address the following questions in detail. We look forward to your timely
response. Please confirm that you have received this email. Thank you.
The EPA issued a health advisory of 70 parts per trillion for C8, a precursor to GenX in the
manufacturing of Teflon.
The Swedish government published asafe level for I I perfluorinated compounds of 90 parts per trillion.
You have stated that the safe level for GenX indrinking water is70,909parts per trillion.
1) Can you provide a detailed description (show the math) for how you established 70,909 ppt as the
safe level?
2) What peer -reviewed scientific research did you use to reach that number? What is the title of the
paper(s) and who are the authors? Who funded the research?
3) Did you attempt to find additional research on safe levels of perfluorinated compounds in drinking

4) Did you find research that indicated safe levels that were lower than 70,909 parts per trillion?
5) If so, why did you chose to use 70,909 parts per trillion as the advisory level?
6) Is your safe level for acute exposure or long-term exposure? Are there different numbers for these?
7) Is your number the same for sensitive populations such as pregnant or nursing mothers, children,
orpeople who may boill?
8) Did you consider the combined effects nfthe seven perOunhnet*dcompounds found inthe Kneppo
9) Are you developing safe levels for the other perfluorinated compounds detailed in the Knapp*.
study? For 1-4 dioxane?
10) Have you read EPA's statements regarding their concern over the dangers of GenX?
