Subject: Wilmington GenX Sampling/Analysis
Thank you all for participating in Tuesday's call intended to coordinate efforts and facilitate communication with respect
towater sampling/analysis in Wilmington. My notes from the meeting are below. If correction or clarification is
needed, please "respond aU"
* NCDE{l Chris Johnson (PO[);Dana Satterwhite; Mark ?; Helen Perez
* Region 4: Scott 8ivertsen
w EPA/ORD/NERL: Tim Buckley; Mark5trynar; MyriamK4edina-Vera;Andy Lindstrom
The agenda for discussion included the following:
1. What question are we attempting to address with this sampling effort?
2. What isthe sampling design?
3. What isthe status and timeline ofthe CyAPP?
4. Given split sample analysis (contract lab and NERL lab), how will differences in reported concentrations be
managed?
S. What isthe plan for communicating results and who has the lead?
6. What isthe project timeline?
7. Dom/eneed on -going coordination meetings?
OEQ-CFVV_00021468

Action items / notes include:
w Chris Johnson was identified asthe PO[for N[DE{l
* The primary question to be addressed by the sampling is whether GenX concentrations have decreased since
concentrations reported inSun etal. JO16paper from samples taken inZ0l3.
* Some aspects ofthe sampling design were described: sampling will beconducted ofsource and finished
drinking water aswell assource effluent. Linda Culpepper was identified asthe person responsible for the
sampling plan who can provide additional detail
* Sampling began Monday 19 June and is planned to continue for three more weeks. Approximately SUsamples
are expected to be collected. Split samples will be sent to RTP and contract lab Test America in Colorado
* Mark Strynarindicated that hecan turn -around samples in 1-2 weeks.
w The QAPP is being developed by Linda Culpepper of NC DEQ but she was not on the call to describe status.
* The list of target analytes has yet to be determined. There is interest in chemicals related to GenX
production. It was suggested that the ana|yte list be determined by consensus among N[ DEQ, R4, and EPA,
RTP.
* The need for blanks and spike samples were discussed. |twas suggested that spike samples beinthe
concentration range of7Un8/L
* The contract laboratory conducing analysis isTest America inColorado. Mark Strynarisgoing tucontact the lab
toobtain analysis method.
* Communications plan has not been developed; N[DE(lhas the lead
w Samples will be delivered in batches. N[ DE{lwill deliver samples to RTP.
* Tim Buckley agreed toset upweekly meetings for planning and coordination
* Mark Strynar and Tim Buckley will be visiting R4 Athens lab 6/26 & 27 to provide tech transfer on GenX analysis
