We do not have a formal project plan for this project. Our existing SOPs are used during our sampling events.|
forwarded a copy of the EPA sampling plan, sent to me last week by Andrew Lindstrom, to the two regional offices when
the EPA sampling kits were delivered. | also forwarded your bullet points regarding information to be included on the
field sheets. The regional samplers were asked to follow the EPA plan as closely as possible during weeks two and
three. We are putting together an outline ofour sampling protocol atthis time. David Huffman, the OkAofficer in the
Water Quality Section is helping put this together and it will beforwarded toyou when complete. We hope that this can
suffice asanaddendum tothe existing CkAPPfor your laboratory. |finsufficient, vvecan craft formal documentation
based on these notes. If that is needed, it would be helpful to see the format that EPA uses for QAPPs. Our existing
sampling SOP is many years old and is currently being updated by the new WQ QA officer. The procedure isunchanged
in essence, but equipment brands, etc, are being edited and the SOP iscurrently in preliminary draft form.
If I've misunderstood any of your questions or haven't addressed them to your satisfaction, let me know and I will work
on them further.
It was a pleasure to meet all of you on Friday and I hope to get back to the facility when there is less urgency of timing
than was the case that day.

Subject: RE: Discussion for sampling and analysis in Wilmington
Hello Mark and Chris,
Thank you for bringing this to my attention and for reaching out to make sure that proper CIA documentation is in place.
Please see below for mythoughts and follow upquestions.
0 1 agree with Mark that it's important to include the quality control (QC) samples such as trip blanks and spikes
whenever possible.
Question from Chris: Mark, can you tell /neabout the requirement related tuthe QAPP? bthis something that
needs to be "customized" for the particular project or is it a copy of our standard sampling procedure? Does EPA
need a copy of the QAPP before testing begins?
Sania's reply: | understand that the NC D8Iisresponsible for sample collection whereas EPA isresponsible for
sample analysis.
Chris - Can you please confirm that the 'standard sampling procedure'will be the standard operating procedure
(SOP) used to collect samples? Also, is there a separate QAPP that outlines the other aspects of the particulars of
this project /e.g,the who, what, when, where, and why cƒthe prcjecd?Please dosend copy o/both the W[DEQ
standard sampling procedure as well as QAPP so that we may have a copy of the documentation that reflects the
{Aplan for the sample collection portion ofthe project.
Note that the EPA requirement for QA project plans (QAPPs) is to have an approved QAPP in place prior to the
start of sample collection and/or sample analysis. QAPPs are project specific so that the who, what, when,
where, why, and how of a project can be documented as the plan to follow for a particular project. This doesn't
mean that things won't or can't change. The key is to document the plan prior to the start of the project via an
approved QAPP and to be sure to document any changes to the plan during the project.
In this case, the scope of EPA's work is with the sample analysis only. It is understood that NC DEQ is responsible
for the sample collection and that NC DEQ has their own SOP and QAPP associated with the project (to be
confirmed after receipt of these documents). To help ensure QA documentation is complete on EPA's side of the
house, / recommend onaddendum toMonk'sexisting QAPPAs Mark stated, the NCDE{Istandard sampling
procedure as well as existing QAPP can be referenced, and any detail that is unique to this project can also be
outlined in the addendum for sample analysis such as reference to the specific analysis SOPs to be used.
Mark To give you an idea of what info to include in the addendum, below is a brief list. Please let me know if
you'd like to discuss what to include.
Why (Project Background) — Why is this project being conducted? Basically, what's the issue at hand and what
do you want to accomplish (i.e., project goals/objectives)?
Project is being conducted to determine current values for GenX and related constituents in the Cape Fear
River Basin sampling points as follow up to replicate analysis conducted by Sun et. al. reported in 2016 with Dr.
Knappeand Mark Itrynar. Sampling and analysis conducted in 2013-2014 indicated the presence of GenX
thought to be released by the Chemours chemical manufacturing plant in Fayetteville, NC along with several
other constituents. NC Department of Health and Human Services is in need of current data on the level of
GenX in the river basin and drinking water systems downstream to evaluate human exposure in regard to health
OEQ-CFVV_00021718

screening |eve(s) for public consumption. Information unadditional ether constituents will beused tocompare
past levels with current concentrations as health studies continue to be evaluated.
What/When/Where (Project Description) Summarize work tobeperformed and expected products. What is
the project schedule? Where are samples going to be collected, what types of samples are going to be collected,
and how many samples do you plan to collect? You will want to specify NC DEQ!s specific role and EPA's specific
role inthe project (ie,EPA isreceiving samples from NCDEC\who will follow their own protocols and OY4
North Carolina Division ofWater Resources staff inthe Fayetteville and Wilmington Regional Offices will conduct
water sampling in accordance with QAPP at locations in the Cape Fear River basin at: Chemours outfall 002;
B|aden Bluff water intake, finished water, and mxe||; Lower Cape Fear Water and Sewer Authority intake;
International Paper intake; International Paper finished water; [ape Fear Public Utility Authority finished water;
Pender County public utility finished water; Brunswick County public utility finished water; Cape Fear Public
Utility Aquifer Storage and Recovery well; and Wrightsville Beach water supply well.
Two grab samples will be collection on Mondays at each of the Fayetteville locations and on Thursdays at each
the Wilmington locations during each of the three weeks beginning June 19, June 26 and July 3, 2017 to
determine current concentrations ofGenXand related ether chemicals in the River basin. One set ofsamples
will be shipped to Test America in Colorado for GenX analysis, and one set of samples will be delivered to the
EPA ORD lab in RTP, N[for GenXand related compounds analysis to replicate analysis conducted in the Sun et
ai report which included Dr. Knappe and Mark Strynar. Data will be used by the Department ofHealth and
Human Services to evaluate human exposure in comparison to health screening level(s) for GenX and other
related compounds aohealth study information |savailable. EPA ORDwill follow their own protocols and QA
plans.

Thanks for the reply, Mark.
| received word from the Wilmington KO and it looks like they will need 16 bottles to finish out their projected
sampling. I haven't heard from the Fayetteville office, but based on what we've received from then for the first
sampling event, I would think they need approximately 12 bottles to finish up. This isall based onthe sampling being
done this week.
Given the tight time frame for next week's sampling, vvewill probably need todrive the sample kits down to Fayetteville
tomorrow afternoon ifpossible. I would also like to deliver the first set to you if we receive Wilmington's set in
time. Either way, if there is any way we can have the sample kits ready tomorrow I would have time to get them to the
samplers.
Thanks once again for your help on this project.
