State of Minnesota v. 3M Co., Court File No. 27-CV-10-28862
STUDY SUMMARY FOR WORK PERFORMED DURING 1977-1979 TEST SUBSTANCE Identity: Perfluorooctanesulfonate; may also be referred to as PFOS or FC-95. (1-Octanesulfonic acid, 1,1,2,2,3,3,4.4,5,5.6,6,7.7,88,8-
heptadecafluoro-, potassium salt, CAS # 2795-39-3)
Remarks field: The test substance is a white powder of uncharacterized purity. The attached is anoverviewcreated in 19for7 stud9ies completedfrom 1977 to 1979. Robust summaries have already been submitted for many ofthese studies. Others have not been summarized due to the fact new studies exist that supercede these or they are being repeated. STUDIES Water solubility; biodegradation; soil sorption; octanolwater partition coefficient; Static Acute Toxicity to Bluegill Sunfish (Lepomis
macrochirus); Static Acute Toxicity to Rainbow Trout (Salmo gairdnen);
AStcauttiec TAcouxtiecTiotxoyicDitayphtoniFaatmhaeganda;MiCnhnroowni(cPFilmoewphTahlreosupgrhomSetluadsy);onStatic Fathead Minnow (Pimephales promelas)
DATA QUALITY
Reliability: These studies have been assigned Kiimisch rankings = 2.
`They satisfied criteria for quality testing at the time performed, but have some deficiencies. In many cases actual concentrations were not measured. The value was determined by indirect measurement (e.g., solubility) or using nominal concentrations (e.g., aquatic toxicity). In some cases, the analytical methodology itself was questionable. Additionally,
these studies lack sufficient characterizationofthe test substance purity.

FC 95
This material is an off-white powder, having a molecular weight of 538 and the chemical structure shown above.
This report consolidates all available information in the
areas of aquatic toxicity, soil sorption studies, degradation, water solubility and partition coefficients and defines the probable environmental risk of FC 85.

The primary purpose of this report is to provide a single
source for all environmental data generated relating to FC 95 and to provide an analysis of potential environmental risk.
The environment may be considered to be a closed system
