BIODEGRADATION (BOD/COD)
TEST SUBSTANCE____________________________________________
Identity: A mixture containing perfluorooctanesulfonate, which may also be referred to as PFOS, FC-95, or as a component of FC-787 or FC787X. (1-Octanesulfonic acid) (CAS # 2795-39-3).
Remarks: The 3M production lot number was not noted. The test sample is FC-787. Current information indicates it is a mixture of 0.73% PFOS, 10% diethylene glycol monobutyl ether, 79.74% water, 5% ethylene glycol, 1.47% propane Sultone foamer, 0.73% sodium octyl sulfate, 0.73% sodium decyl sulfate, 0.75% xanthan gum, 0.75% magnesium sulfate, 0.10% N-(3chloroallyl)hexaminium chloride, and 0.05% benzotriazole.
The following summary applies to a mixture with incompletely characterized concentrations of impurities. Data does not accurately reflect the degradation potential of the fluorochemical component o f the test sample.
METHOD:----------------------------------------------------------------------------------------
Method: EPA or other acceptable methodologies GLP: No Year completed: 1990 Contact time: 20 days Inoculum: Source not given.
RESULTS______________ :---------------------------------------------------------------
Chemical Oxygen Demand (COD):
350,000 mg/kg
320,000 mg/kg (replicate)
Biochemical Oxygen Demand (CBOD):
5-Day:
160,000 mg/kg
10-Day:
220,000 mg/kg
20-Day: 200,000 mg/kg
Remarks: Testing was conducted on the mixture as described in the Test Substance Remarks field. The values reported apply to that mixture and not the fluorochemical proportion alone.

DATA QUALITY Reliability: Klimisch ranking 3. Study lacks description and records of the method followed. The inoculum is not properly characterized. The sample purity was not properly characterized and the study lacks analytical confirmation of the amount of fluorochemical proportion in the solution.

Mr. Garry Hilling Environmental Laboratories/3M Building 2-3E (9), 3M P.O. Box 33331 St. Paul, MN 55133
Mr. Hilling:
This is to modify the CBOD results reported on SERCO Laboratories' report 854 dated 6/13/90, 3M H1608-1.
Based on the density performed on the sample which was re submitted on 9/25/90, the CBOD results are as follows:
BOD, Carbonaceous, 5-day, mg/kg - 160,000 b o d , Carbonaceous, 10-day, mg/kg 220,000 BOD, Carbonaceous, -*s-day, mg/kg * 200,000
The calculation performed was: CBOD mc/L - CBOD mg/kg
density g/mL
(g/mL - kg/L)
Please refer to the COD and density results on SERCO Laboratories' report 2869 that is included with this letter.
Sincerely, SERCO Laboratories
