AR226-2459 From: Rik A Brandenburg on 05/26/99 09:14 AM CED To: cc: Subject: Roger J ZipfeI/AE/DuPont@DuPont Seiichi Tanaka/PO/DuPont@DuPont Re: C-B in drinking water || Roger, We have no data for c-8 in drinking water and a lot of data on C-8 in ground water. The last report I have has data of 1995. the first aquifer contains 0.1 - 28 ppb of C-8, the second aquifer 0.1 - 0.2 ppb. drinking water is withdrawn from the third aquifer, far away from the plant. We have lots of reports, but they are all in Dutch. P.S. This is the second time I receive a message from you were you put the message in the subject. This means that when I move the selection bar to your message, it is blank. I have to open it, to read it. No big deal, but I thought you should know. regards, Rik Roger J Zipfel rT'T;^ ?' .-A';v Roger J Zipfel IS'-Kt-w 25-05-9920:01 To: cc: Subject: Rik A Brandenburg/EUR/DuPontla'DuPont, Seiichi Tanaka/PO/DuPontODuPont C-8 in drinking water Rik, and Tanaka-san, we are preparing lor a meeting to discuss C-8 in drinking water due to soms recent findings of high C-8 in Parkersburg groundwater. You have in the past given me some data on C-8 levels in drinking water at your sites. I specifically have the data from Dordrecht dated in 1993.1 don't have any data on C-8 levels in drinking water at Shimizu. Is it possible for you to look at your records and see if there is more recent data from Dordrecht or any data from Shimizu on C-8 levels in drinking water on the site. I would also like to know the current source for the drinking water at each of the sites. This information will be most valuable if available by thursday morning, Wilmington USA time.
