Dear Mr. Hefter:
2] 3
Our law firm currently serves as class counselfor a group of tensof thousandsofcifgens `whose drinking water is contaminated with ammonium perfluorooctanoate (a/k/a APFO/PFOA/
FC-143/C-8) (hereinafter "C-8") released from EI duPont de Nemoursand Company's ("DuPont's") Washington Works fluoropolymer manufacturing facility along the Ohio River in `Wood County, West Virginia. During the courseofthis lawsuit (styled Jack W. Leach, et al. v. EI duPont de Nemours and Company (Circuit Court of Wood County, WV, Civil Action No. 01-C-608)) and a prior lawsuit during which we represented membersofthe Tennant family who claimed that C-8 released from DuPont's Dry Run Landfill in Wood County, WestVirginia, caused the deathofseveral hundred headofcattle and other damages, including damage to the Tennant's own health (styled Wilbur E. Tennant, et al., v. E.I. duPont de Nemours & Co., Inc. (Case No. CA-6:99-0488 (S.D.W.Va.)), we obtained and reviewed nearly one million pages of documents from DuPont's intemal filles relating to C-8.
BEN -80-37 feipa-foris 00000 `Among the documents obtained from DuPont to date are documents relating to DuPont's.
`pregnancy outcome study among its female workers exposed to C-8 at its Washington Works plant back in 1981, and DuPont's knowledgeofthe presence of C-8 in public drinking water supplies at levels exceeding DuPont's internal community exposure standards. The
Environmental Working Group ("EWG") referenced some of these data in its April 11, 2003,

letter asking USEPA to investigate DuPont's actions with respect to disclosureofbirth defect and drinking water contamination data to USEPA, pursuant to Section 8(e) of TSCA, which your office asked DuPont to explain in your letter dated May 22,2003. (AR-226-1318)
Becauseof the potential likelihood of substantial harm to our class members or to the
`public interest from an incorrect understanding or assessmentofthe birth defect and drinking
`water contamination data at issue, we submit the following information obtained from DuPont
for consideration in connection with your Agency's evaluationof the statements made by DuPont's counsel on this matter in its June 20, 2003, letter responding to your May 22, 2003,
letter:
1
March 20, 1981 - 3M submitted a TSCA Section 8(c) notice to USEPA,attaching
its report finding birth defects in the eyes ofrat fetuses exposed to C-8.
(Exhibit A (EID072034-45)) That same day, 3M notified DuPontoftheeye
defect findings. (Exhibit B (EID079423))
2
March 25, 1981 - DuPont's Medical Director, Dr. Bruce Karrh, summarized the
birth defect data received from 3M and DuPont's knowledgeofthe pregnancy
outcome status of Washington Works employees exposed to C-8 as follows:
At present, about 50 womenemployeeshav potential for exposure
to C-8 compounds at Parkersburg. .. . Ofthe 50 female employees
at Parkersburg, three are pregnant now and 2 probably pregnant. `The reproductive capabilityofthe others is unknown at present. One employee who worked in the area had a miscarriage followed immediately by a normal pregnancy with a recent normal outcome. Her potential C-8 exposure throughout both pregnancies was
described as "heavy." There was one recent abnormal pregnancy outcome with one female employee at the Plant, but she did not
`work where there was any possibilityofexposure to C-8.
Of the employees presently pregnant, one is in her 7th month, one in her 5th month, one in her 3rd month, and 2probably just pregnant. One complicating factor is that C-8 is retained in the
body for a very long time after exposure ceases.
`The plan at present is to convene a meeting after Dr. Staples
reviews 3-M's work, probably by March 27... .If the 3M study is valid, womenofchild-bearing potential will probably be excluded
from jobs where there is potential for exposure to C-8 compounds,

total intake allocated to water; and 80% to air since our CEG for C-8 hasalready `been established for air" and DuPont's own, internal air `modeling already had
confirmed that nearby residents would be exposed to C-8 through the Washington Works' air emissions. (/d.)
3s. June 11, 1991 - DuPont's AEL Committee selected 1 ppb as the CEG for C-8 in
`community drinking water, assuming potential community exposure through both air and drinking water. (Exhibit FF (EID097177-85) DuPont defined the purpose
ofits CEG at that time as follows:
CEGs are exposure guidelines that are expected to be withoutany effect to members of the community during continuous 24-hour a day exposure to a chemical or physical agent. CEGs may be recommended for air or water or both. As with AELs, CEGs are recommended based on the best available information from
industrial experience, animal toxicity studies, controlled human exposure studies, and epidemiological findings. However, because.
ofthe variabilityofsensitivities of members ofthe. `community (e.g., the infirm, the old, the young, pregnant females, etc), versus the
healthy worker involved with an AEL, a larger uncertainty factor
needs to be used in extrapolating thesedatato a CEG. (/d., at EID097179)
36. September1991 - DuPont reviewed additional public drinking water results from the summer of 1991 confirming C-8 in the LPSD public drinking water supplied by the LPSD's original wells as high as 3.9 ppb,andas high as 2.4 ppb in the LPSD's new wells, now located "2.7 miles south-southwest of Washington Works." (Exhibit GG (DE000245-56)
37. Although the C-8 AssessmentofToxicity Team ("CAT Team") established under a November 2001 Consent Order between DuPont and the Stateof WestVirginia
announced that it had selected a 150 ppb "screening level" for C-8 in drinking
`water in Mayof 2002, DuPont has not changed its internal 1 ppb CEG for C-8 in
community drinking water since 1991 and, with respect to the relationship between that CEG and "screening levels," DuPont used its CEG to calculate a 3 ppb
