BIODEGRADATION (BOD/COD)
TEST SUBSTANCE
Identity:A mixturecontainingperfluorooctanesulfonawthei,ch may alsobe referredtoas PFOS, FC-95, or as a component of FC-787 or FC787X. (1-Octanesulfoniaccid)(CAS # 2795-39-3).
Remarks: The 3M productionlotnumber was not noted.The testsample isFC-787. Currentinformationindicatesitisa mixtureof0.73% PFOS, 10% diethyleneglycolmonobutyl ether,79.74% water,5% ethyleneglycol,1.47% propane Sultonefoamer,0.73% sodium octylsulfate0,.73% sodium decyl sulfate0,.75% xanthan gum, 0.75% magnesium sulfate0,.10% N-(3chloroallyl)hexaminiucmhloridea,nd 0.05% benzotdazole.
The followingsummary applies to a mixture with incompletely characterizedconcentrations of impurities.Data does not accurately reflectthe degradation potentialof the fluorochemical component of the testsample.

Mr. Hilling;
This is to modify the CBOD results reported on SERCO Laboratories' report 854 dated 6/13/90, 3M H1608-1.
Based an the density performed on the sample which was resubmitted on 9/25/90, the CDOD results are as follows:
BOD, BOD, BOD,
Carbonaceous, 5-day, mq/kq
Carbonaceous, lo-dayt mg/kq
Carbonaceous,-2:5-day,
mg/kq
160,000 220,000 200,000
The calculation performed was: - CBOD mg/T-L--- CBOD Mg/kg density g/mL
(g/mL - kg/L)
Please refer to the COD and'donsity results on SERCO Laboratories' report 2869 that is included with this letter.
