BIODEGRADATION (BOD/COD) TEST SUBSTANCE Identity:A mixturecontainingperfluorooctanesulfonatweh,ich may also be referredtoas PFOS, FC-95, oras a component ofFC-206C and L-5439. (1-Octanesulfoniacdid, 1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8,8-heptadecafploutoarsos-i,um salt,CAS # 2795-39-3) Remarks: The 3M productionlotnumber was 501.The testsample is referredtoas L-5439 and FC-206C. Currentinformationindicatesitisa mixtureof0.73% PFOS, 76.09% water,15% diethyleneglycolbutylether, 4% urea,1.55% sodium octylsulfate1,.47% hydroxyfoamer,1.05% polyoxyethylenemonooctylphenylether,0.06% sodium laurylsulfatea,nd 0.05% benzotriazole. The followingisan abbreviated summary of multiplebiodegradation studies on FC-206C. These studies apply to the testsample as a mixture with incompletely charactedzed concentradon of impurities. Data does not accurately reflectthe biodegradadon potentialof the tluorochemical component of the testsample.. METHOD: Methods: Variousmethods. Most notspecified. Type: BOD (Carbonaceous and Total) GLP: No Year completed: 1981-1982 Contact time:20 days Inoculum: Stalesewage from 3M's CottageGrove faciliatnyd seed from varioussources.

This testing was conducted at the 3M Env and four outside laboratories. TheirreosnumlenttsawlerLeabmoorraetory 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 withs a nitrification inhibitor (the C-BOD results) and ome of the tests were done using a seed unlikely to contain a large population of nitrifying organisms (sIeed from the Knoxville waste treatment system). While had previously thought that their results were due to nitrification, I must now say htihgaht BIODdorensoutltksn.ow why Galbraith gets such atypically pIrepplaarnintgo use the average data from all of these tests in for our Ma-1eurriaPlroSdaufctetyEnDvaitroanSmheneteatls.DatIaf Sheets and input you have any questions V, ,,oncerningthese data, please feel free to contact me on 778-5079.
