Hi Jessica,
Detlef just called me about is very eager to hear from someone on this matter. I told him that I hadn't been
involved in any meetings recently, but that I would touch base with you to see if you had heard anything and
that we would get back with him.

Subject: PFASs in the Cape Fear River watershed
Hello everyone,
I am following up on my email from November 23, 2016 to see whether DEQ staff have discussed the PFAS
contamination in the Cape Fear River downstream of the Chemours plant. A reporter from Wilmington contacted me,
and one of the questions he would like me to answer is what DEQ is doing about the situation. The reporter read the
paper I shared with you in November (also attached here again).
A recent study from Sweden suggests that GenX, one of the compounds we are finding in Wilmington's water, is as toxic
as or more toxic than PFOA, the compound it is replacing.
I will try and reach you by phone this morning as well.
Thank you,
Detlef
Hello everyone,
1 am attaching a paper we published this month in ES&T Letters. We studied the occurrence of per- and polyfluoroalkyl
substances (PFASs) in the Cape Fear River watershed. Legacy PFASs, such as PFOA and PFOS dominated the PFAS
signature in the Haw River. In contrast, new fluorinated alternatives such as GenX, a replacement for PFOA, were very
high in Wilmington (and by association also in Brunswick and Pender). None of the newly discovered compounds being
discharged by the Chemours plant south of Fayetteville are removed by the advanced and conventional treatment
processes employed in the Sweeney WTP in Wilmington. Also, many of the compounds are essentially non -adsorbable
on activated carbon. I think it would be useful to discuss the results. A large number of people are exposed to high levels
of PFASs through their drinking water!
Best regards,
Detlef

Hello!
I think you all know that Carrie Ruhlman has moved on from DWR. I'll be taking over coordination of the
1,4-dioxane monitoring project. Please feel free to contact me if I can be of assistance in this regard.

Attached are the results from DWR's quarterly surface water monitoring from January -July 2016. We
will sample again in October, then prepare a summary report for October 2014-October 2016 data by
the end of the year.
Warm regards,
