Subject: RE: State releases first water quality data, updated health information for6enX in Cape Fear River
Want to clarify that the performance standard for total chromium 10 ppb hasn't changed...
Also, the new health goal (iescreening level?) for GenXis non -enforceable, so what practical effect does lowering it
have?
Thanks!

State releases first vvakmr quality data, updated health information for GenX in Cape Fear River
Treated drinking water concentrations trending down; latest levels below updated health risk threshold

assessment for concentrations ofthe unregulated compound Gen}Cinfinished, ortreated, drinking v/ator.
The revised health goal for exposure to Go@{in drinking water is|40nanugrmnper liter (also referred to asparts per
Samples were analyzed uithe iJ.3. Environmental Protection Agency lab ioResearch Triangle Park and ui'rest America, olab
inColorado under contract ioChomour.
Data from samples collected June |9and July 6show that the most recent results of finished, mtreated, water in all but one
facility were below the N.C.Department ofHealth and Human Services' health goal of|40parts per trillion. The data also

reveal that concentrations of GenX are trending downward.
Although no information is available about recreational health risks, people should refrain from swimming near the Chemours
facility.
"Our goal is to protect the safety and health of all North Carolinians," said Mandy Cohen, secretary of the N.C. Department of
Health and Human Services. "We are working closely with our partners at the Department of Environmental Quality to
understand and communicate information in a timely manner, to help those impacted."
N.C. Department of Environmental Quality Secretary Michael Regan said:
"Safe drinking water is a top priority for this administration, and DEQ takes seriously 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 samples collected at 13 sites 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 N.C. Department of Health 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 of Health and Human Services today updated its initial preliminary health assessment for GenX,
the unregulated chemical compound recently identified in the lower Cape Fear River.
This updated health goal of 140 parts per trillion is expected to be the most conservative and health protective for non -cancer
effects in bottle-fed infants, pregnant women, lactating women, children and adults. This health goal is lower than the health
goal in the initial preliminary health assessment. This changes reflect information from new data. Detailed information
regarding the initial and revised assessments are posted online at: hops;//nedenr.s3.amazoniws.com/s3fs-
publie/GenXfNC%20DHHS%20Risk%20Assessment%20FAti%20Final%20Clcan%20071417%20PM.pdf.
Lower second week values reflect reduced exposure to GenX when, at the urging of state, local officials and concerned citizens,
Chemours on June 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 wastewater diversion had started. DEQ inspectors confirmed this
week that Chemours 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 GenX website:

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 GcnX.
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 GcnX concentrations in the lower Cape Fear River.
