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-203C and L-5440. (1-Octanesulfonic add, 1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8,8-heptadecafluoro-, potassium salt, CAS # 2795-39-3)
Rem arks: The 3M production lot number was 501. The test sample is FC-203C. Current information indicates FC-203C is a mixture of 1,47% PFOS, 60% water, 30% diethylene glycol butyl ether, 3% sodium octyl sulfate, 3% hydroxy foamer, 10% polyoxyethylene monooctylphenyl ether, 0.12% sodium lauryl sulfate, and 0.05% benzotriazol.
The following is an abbreviated summary o f multiple biodegradation studies on FC-203C. These studies apply to a mixture with incompletely characterized concentration o f impurities. Data does not necessarily reflect the biodegradation potential o f the fluorochemical component of the test sample.
METHOD:__________________________________________________ .
Methods: Spedfic methods not noted. Type: Aerobic BOD and Carbonaceous BOD and Dichromate reflux COD GLP: No Year completed: 1981 -1 9 8 2 Contact time: 20 days Inoculum: Activated sludge mixed liquors from various sources.
RESULTS_______________________________________________________
Chemical Oxygen Demand (COD) range:
730,000 - 950,000 mg/kg
Biochemical Oxygen Demand (BOD) range: 5-Day: 10-Day: 20-Day:
56,000 - 519,000 mg/kg 370,000 - 620,000 mg/kg 440,000 - 800,000 mg/kg
Carbonaceous-Biochemical Oxygen Demand (C-BOD) range: 5-Day: 47,000 - 357,600 mg/kg 10-Day: 1 4 0 ,0 0 0 -5 8 0 ,0 0 0 mg/kg 20-Day: 410,000 - 730,000 mg/kg

R em arks: These studies were conducted by various laboratories. Variability in the results may be due to the various methods used. C O N C L U S IO N S _________________________________________________ No reliable conclusions can be derived from this study. The indication is that the majority of the product components are readily biodegradable. Subm itter: 3M Company, Environmental Laboratory, P.O. Box 33331, St. Paul, Minnesota, 55133 DATA QUALITY___________________________________________________ Reliability: Klimisch ranking 3. Study lacks description and records of the method followed. Inocula were not properly characterized. The testing was conducted on a mixture with chemicals having varying degrees of biodegradability, leading to potential misinterpretation of the results. The studies lack information on the purity of the test substance and lack actual measurements of the concentration of fluorochemical in the solution. R E F E R E N C E S ____________________________________________________ Test was conducted by multiple vendors at the request of the 3M Company, 3M Lab Request Numbers 6811S, 7736, 7737, 7738, 7903, and 7625.

Dear Dave:
Sample 7858-1 was analyzed for 5-day, 10-day and 20-day BOD and COD. The samples were analyzed with and without nitrification inhibitor. The seed bottles for the 10-day and 20-day seed correction were inadvertently not analyzed. Consequently, the 10-day and 20-day BOD's cannot be accurately calculated. The 5-day BOD, 5-day C-EDD and COD values were reported.
If you have any qustions on the above, please contact me.

Attached is a summary of the BOD, carbonaceous BOD, and COD test results on FC-203C, FC-206C, and FC-780B. This testing was conducted at the 3M Environmental Laboratory and four outside laboratories. The results were more variable than I had anticipated. The Galbraith results on FC-206C were typical of their result from past testing, i.e., they had a very high BOD2o/COD ratio. This occurred despite the fact that some of this testing was done with a nitrification inhibitor (the C-BOD results) and some of the tests were done using a seed unlikely to contain a large population of nitrifying organisms (seed from the Knoxville waste treatment system). While I had previously thought that their results were due to nitrification, I must now say that I do not know why Galbraith gets such atypically high BOD results. I plan to use the average data from all of these tests in preparing ^pur Product Environmental Data Sheets and input for our Material Safety Data Sheets. If you have any questions ijpncerning these data, please feel free to contact me on 778-5079.

* Calculated BOD's from different dilutions were very inconsistent. Pace agreed to repeat this work but inadvertently lost their repeated test results as well. We did not request a third testing nor did we include these values in the averages.
