BIODEGRADATION (BOD/COD) TEST SUBSTANCE Identity:A mixturecontainingperfluorooctanesulfonawthei,ch may also be referretdo as PFOS, FC-95, or as a component ofFC-203C and L-5440. (1-Octanesulfoniaccid, 1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8,8-heptadecapfoltuaosrsoi-u,m salt,CAS # 2795-39-3) Remarks: The 3M productionlotnumber was 501.The testsample is FC-203C. CurrentinformatioinndicateFsC-203C isa mixtureof 1.47% PFOS, 60% water,30% diethyleneglycolbutylether,3% sodium octyl sulfate3,% hydroxyfoanier,10% polyoxyethylenemonooctylphenylether, 0.12% sodium laurylsulfatea,nd 0.05% benzotriazol. The followingisan abbreviatedsummary of muldple biodegradation studies on FC-203C. These studies apply to a mixture with incompletelycharactedzed concentrationof impudties.

The sampleswere analyzed with and without nitrification inhibitor. The seed bottles for the 10-day and 20-day seed correctionwere inadvertentlynot analyzed. Consequently,the 10-day and 20-day BOD's cannot be accurately calculated. The 5-day BOD, 5-<hyC-.,EDD.anCdOD values were reported. If you have any questions on the above, please contact me.

REINER - ENVIRONMENTAL LABORATORY/EE Sub*t-- MIL-SPEC AFFF BOD AND COD TESTING Date: MAY 25, 1982 236-2A-01 & PC - 21-2W-5 Attached is a summary of the BOD, carbonaceous BOD and COD test results on FC-203C, FC-206C, and FC-780B.1 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 BOD20/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 preparinga'vur Product Environmental Data Sheets and input for our Material Safety Data Sheets. If you have any questions Voncerning these data, please feel free to contact me on 778-5079.
