RALEIGH — State officials today released the first results of water quality samples for GenX concentrationsindhe[ape
Fear River. Drinking water outcomes have led state public health officials to maintain the preliminary assessment of a
|ovv public health risk
The findings reflect water quality data from samples collected Lilong 12 sites inthe Fayetteville andVVi|min8tonareas
between June 19 and June 29. As expected, results show higher concentrations near the point where Chemours'
Fayetteville manufacturing facility was discharging the unregulated compound into the Cape Fear River, with much
lower figures observed 70 miles downstream in the Wilmington area.
In some cases samples analyzed at the U.S. Environmental Protection Agency (EPA) lab in Research Triangle Park are
lower than those identified bya,acertified lab inColorado under contract to[hemours.For example, raw
water atthe [hemounoutfaUranges between 21,76Qand 39,QUOparts per trillion the first week and between 15,250
and 19,000 parts per trillion the second week. Finished drinking water at the Cape Fear Public Utilities Authority
(CPFUA) Sweeney site was between 726 and 1,100 parts per trillion the first week and 100 to 110 parts per trillion the
second week.
Lower second week values reflect reduced exposure to GenX when, at the urging of state and local officials as well as
concerned citizens, Chemours on June 20 began diverting wastewater containing the contaminant into storage
containers tobeshipped out ofstate for incineration. Add content about additional GenXsounces—
Results from all 1Itest sites for the first two weeks of water sampling can be found on the N.C. Department of
Environmental Quality's GenXw/ebshe: State officials caution
against comparing raw and finished drinking water values from same -day samples, as water that had completed a
treatment cycle would have started the process with an earlier, and potentially different, exposure to GenX.
While |h1|e is known about GenX, these data indicate that the preliminary DHH8 assessment of |oxv public health risk
remains accurate. Toda/udecision was based on consultation with EPA and the Centers for Disease Control and
Prevention ([D[). 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.

Some local utilities and governments also are conducting independent water sampling. Since the protocols inplace for
these samplings and related analysis are not consistent with rigorous DEQ and DHHS practices, they are not being
factored into the state'uhealth risk assessment.
Results from subsequent weeks of water sampling by state officials, originally planned for three weeks but since
increased to a total of six weeks to provide a more comprehensive report, will follow.
For the state process, water samples are collected by DBlstaff, which provides equal portions to TestAmerica and the
EPA lab. Staff at each lab test samples for the presence of GenX, then send reports to DEQ for quality assurance and
quality control review to ensure accuracy. These vetted results are then provided to DHHS, which performs a health risk
analysis.
