Sharing the presentation. Slide 18 has the list of other chemicals of concern.
Cyndi — where at the lab can we securely store additional samples (250 ml bottles) that will be
taken to EPA ORD lab in RTP for analysis? Connie had the good idea to store them in one area
as we work out arrangements with EPA. I hope to have the coordination in place this week.
WiRO and FRO have not received their sampling kits from Test America yet. If Mark receives
the sample containers this morning, they could get their samples taken today. If not, it will be Weds.
Please let us know as questions arise. Appreciate all the coordination on this project.
Thank you.

Subject: perfluoroalkyl ether carboxylic acids to test for
Linda,
The two perfluoroalkyl ether carboxylic acids we are interested in having the lab test for are PFMOAA and PFO2H
The MS/MS transition range for PFMOAA is 180.0 -*85.0
And the MS/MS transition range for PFO2HxA is 245.1---* 85.0
Mark should know that for any samples that biological growth could occur (i.e. instream) Detlef recommends adding
some nitric acid as described below:
Methods used for sample collection are outlined in the NERL/HEASD SOP No. EMAB-113-0 entitled "Sample
Collection Protocol for PFCs in Surface and Well Water (4). The specific sampling method was dependent on the
source of water being sampled; however, the basic process involved rinsing the collection bottle with three
volumes of water followed by filling on the fourth iteration and adding 5 mL of 35% nitric acid as a preservation
agent. Duplicate samples were collected at a rate of 10%. Samples were labeled with unique codes as well as the
DEQ-CFW 00059568

•
appropriate information providing time, date, location and water source type. Samples were maintained at
ambient temperature after collection. All samples were shipped on February 20, 2009 to the RTP PFC laboratory for
analysis, with chain of custody (CoC) forms recording collection, shipment, and receipt (Appendix 1).
Connie and I talked about this afterwards, we may want to hold off analyzing samples for these ethers and learn
what we can about them first. We know they are there and perhaps Chemours and EPA can tell us everything they
know about them first so we can find out if they will be eliminated when the wastestreams from the vinyl ethers is
treated with RO and if they pose any health risks.
