BODICOD resultstorFC-94-X (U sWt ofPFOS) I BIODEGRADATION TEST SUBSTANCE Identity:PerfluorooctanesulfonatLei,thiumsalt;may alsobe referredto as PFOS Lisalt,FC-94, or FC-94-X.

METHOD Method: Carbonaceous BOD. Type: Aerobic GLP: No Year completed: 1994 Contact time (units)S:ee Remarks lnoculum: ActivatedSludge Remarks: The laboratorywas not abletogenerateuseable data for CBOD. The studywas attempted6 times usingdifferenttechniques,but no values couldbe produced. RESULTS Difficultitehsatwere notexplainedinany detailwere encountered when attemptingtogenerate carbonaceous BOD biodegradationdata. The Pace analyststates'The sample has been set6 differenwtays each time withinsufficiednetpletion.The sample eitherexhibitsa toxicittyothe BOD seed materialor does notexhibita CBOD type ofdemand."

After 3-hours of exposure, rep 1 had 35% and rep 2 had 33 % inhibition in respiration rate relative to the controls. For M018-1, PACE was not able to aquire any useable data for CBCD-05,10, or 20 even though nuwx= tries were made. 7he sauple was set 6 differen, t times in 6 different -waysin order to produce a CBM m=ber. The saftpledid not exhibit any depletion as the method reqlures on any of the sets. A detail of what dilutions were tried will be FAXed to S.ue Beach in the foxm of a me= submitted by the Wet Chemistry Supervisor Copies of the raw data will be sent. The laboratory feels it has exhausted all possabilities to dptain useable data and would welcome input from 3K perscmel regarding a solution to th3z matter. Should --vwant to resltmit another sarcple,we certainly would be willing to try the analyses again. mjc PAM 3/2/94 A CBCD-05 value is not able to be detemained m M018-1. The sanple has been set 6 clafferentways each t=e with insufficient depletim. The sample either exh3bits a toxicity to the BCD seed material or does not exhibit a CBM type of demand. mjc PAM 3/7/94 SA24@IIEDATF CODE DESCPAPTICN ESSULT MDL or (95% C.I.) z 1 01/04/94 FC-94-X P-11367 LCfrl 'v@5 (CAFOONACMM) *BCD--10 (C714XIVV-"BOM) *BCE)--20 (CAFGAQCBDM) *OOD DAPHNIA ACUM TEST FISH ACUM TEST - 96 HOUR MlaCMX - EC50 SEE CO*E= SEE CCK4DU SEE CCbt4DU 54000 bG/L 210 bG/L 19 MG/L >1000 MG/L ABOVE ABOVE ABOVE 6 50 ((190-230)) (16-24) CCNTRACT IAB DATA 03/30/1994 ENvnxNMENTRL LABCFMTCFCF FINAL REPCFC LAB RBQLEST No. 14018 SAMPLE DATE CONTINUED EESCRIPTICN TESULT 1 01/04/94 FC-94-X F-11367I= SLLIXE iwl_qp ICN - EC50 >1000]MG/L Pro3ect IeadPzv3.ew:. &Lc-kDate: 2 NDL or (95%C.I.)
