GonX concentrations intreated water continue downward trend based onnew data
Most recent test results all below health goal level
RALEkG|0—Aupart o[itsongoing investigation, state officials today released new data for Gon}{concentrations iowater
samples collected July |Zand |3inthe Cape Fear River.
OEQ-CFVV_00081068

Those test results show that concentrations of the unregulated chemical GcnX in all treated water samples collected by the state
during week four of sampling remained below the 140 parts per trillion developed by the N.C. Department of Health
and Human Services. The health goal represents the concentration of GcnX at which no adverse non -cancer health effects
would be anticipated over an entire lifetime of exposure to the most sensitive populations. State officials expect some
fluctuation in results for measurements in the parts -per -trillion range.
Concentrations of GcnX in the Cape Fear have dropped since the state's investigation prompted Chemours, the chemical's
manufacturer, to stop discharging GcnX into the river. The company is capturing the discharge and sending it out of state for
incineration.
"It's good news that recent test results are showing levels of GenX in treated water trending downward to below our health
goal," said Mandy Cohen, secretary of the N.C. Department of Health and Human Services. "We will continue to monitor these
results to look for any new, emerging trends, and will alert the public in timely fashion as we have new results to share."
Michael Regan, secretary of the Department of Environmental Quality, added that his agency and staff at DHHS continue to
investigate.
"The first four weeks of data gathered as part of our investigation are encouraging, and we're continuing our investigation to
protect the health and safety of those who depend on the Cape Fear River for drinking water and other uses," Regan said.
During his July 24 visit to Wilmington to meet with local officials about GcnX, Giov. Roy Coo�)er ar��io€mced i�e\i step� that the

state is taking to protect drinking water in North Carolina and to get answers for people living in the Lower Cape Fear region.

Water samples collected on July 12 in the Fayetteville area and July 13 in the Wilmington area show all finished water sites
have concentrations of GenX below the health goal of 140 parts per trillion. Samples in both regions collected during week
three also reflected this downward trend, except for one anomaly at the Bladen Bluffs site. Test results for samples taken at this
location came back below the health goal in the most recent round of testing.
Water sampling results can sometimes be influenced by rainfall, changes in river flows and variability in laboratory results.
Moreover, variability in such low concentrations is going to be greater and it's important to put such small concentrations into
perspective, said Sheila Holman, assistant secretary for the N.C. Department of Environmental Quality.
"It is very difficult to understand how minute a particle one part per trillion really is," Holman said. "To better visualize it, one
part per trillion would be represented by a single drop of food coloring in 18 million gallons of water."
DEQ expects to receive and make publicly available another batch of water sampling results next week. DEQ is also working
with the EPA lab to test for concentrations of other compounds related to GenX also noted in a research paper published by
Detlef Knappe, the N.C. State University researcher who worked with the EPA to identify GenX in the Cape Fear River.
DEQ has created a map on its GenX web page to better illustrate the state"s sampling results. Results may be viewed at:
