V AR226-2385 PERSONAL AND CONFIDENTIAL CC: T. A. Foster June 14,1984 XO: J- A Schmid FROM; J. doughty; UPDATE on C-8 IN EATER SAMPLES _ , , . .ia ehrvKrct the C-8 in water data including the most S c e S date fconclude the nsv data confirm the original data. 1 The Du Pont data shows that the test does not see C-8 up rive), and the sampling system does not contaminate he sa p . 2. The second Washington sample had essentially the same C-8 content as the first, l,a Thp new Lubeck sample shows essentially the same concentration tee Sashtegtte ca?le. Thus tee Lubeck Water System as I suspecu or at least the bUDec,c system as the same concentration, ' 4 The original Little Hocking sample was very close to the detection limit for the test/ The concentration now appeals to he below the detection limit. I do not plan to do additional sampling unless further information is needed. The concentrations are very low and in my judgement are not cause for concern.
