Mart in discussion with Sheila Holman, we would like to have a second sample collected from the Chemuurs site totest atthe EPA ORDlab. Holding time of70days | believe did not affect results inaDr. Knappestudy. We don't have the arrangements made yet with EPA are working on that. Thank you all.

Fnmnm:Grryb Julie Sent: Friday, June 16,ZU17S:0]PK4 To: Culpepper, Linda Subject: perfluoroalkyl ether carboxylic acids to test for Linda, The two perfluoroalkyl ether carboxylic acids we are interested in having the lab testfor are PFK8OAAand PFO2HxA. The MS/MS transition range for PFK4OAAisl8U.0 85.0 —�And the MS/MS transition range for PF0JHxAisZ4S.1 85.0 Mark should know that for any samples that biological growth could occur (i.e. instream) Dedefrecommends adding some nitric acid asdescribed 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 ofwater being sampled; however, the basic process involved rinsing the collection bottle with three OEQ-CFVV_00013298 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 rate of1O96. Samples were labeled with unique codes aswell as the 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 ([oC) forms recording collection, shipment, and receipt (Appendix 1). Connie and | talked about this afterwards, we may want to hold off analyzing samples for these ethers and learn what vvecan 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 wastestrearns from the vinyl ethers is treated with ROand ifthey pose any health risks.
