A W IG -o o sn fc-i WATER SOLUBILITY TEST SUBSTANCE Identity: Perfluorooctanesulfonate; may also be referred to as PFOS or FC-95. (1-Octanesulfonic acid, 1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8,8heptadecafluoro-, potassium salt, CAS # 2795-39-3) Remarks: The test substance is a white powder. Sample was taken from 3M lot number 217. Sample was stored under ambient conditions prior to testing. Purity determined to be 90.49% by LC/MS, 1FI-HMR, 19FNMR and elemental analyses techniques. METHOD Method: OECD 105, OPPTS 830.7840, and 40 CFR 796.1840. GLP (Y/N): Yes Year completed: Study completed 1999. Report completed 2000 Remarks: The definitive test consisted of equilibration of an excess amount of test substance with NANOpure water at 30C followed by equilibration at 20C and analyzing subsamples by high performance liquid chromatography with mass spectrometric detection (LCMS). NANOpure water is equivalent to ASTM Type II Designation D1193-91. RESULTS Value (mg/L) at temperature C: 519 mg/L at 20 0.5C. Description of solubility: Slightly soluble. Remarks: Triplicate subsamples were removed from the appropriate bottles after one, two and three days of shaking in a water bath maintained at 30 1,0C and following one day of a 20 0.5C equilibration period. Analysis of aqueous subsamples after one day had a mean analytical result of 459 mg/L (SD = 8.96, CV = 1.95%). For subsamples collected after two and three days, the mean concentration were 537 mg/L (SD = 27.6, CV = 5.14%) and 501 mg/L (SD = 64.2, CV = 12.8%), respectively. 000150 CONCLUSIONS The Day 2 and Day 3 mean solubility concentration were within 15% of each other and were averaged to obtain the overall mean solubility concentration. The overall mean solubility concentration of the test substance in NANOpure water was 519 mg/L (SD = 48.3; CV = 9.31%; N = 6). Submitter: 3M Company, Environmental Laboratory, P.O.

Scheil Project 9970012600 Commercial Chemicals Division, Report No. 49, Feb 6. 1961. G eneral Preface: It has been indicated by 3M personnel that the fluorochemical products produced are invariably mixtures o f compounds with somewhat variable chain lengths and positional isomerism. Given this, the definition o f "solubility" o f a particular product has little meaning except in an operational sense. That is, one can say (assuming that adequate experimental procedures are followed and that appropriate analytical tools are at hand) that the total amount o f fluorocarbon substance dissolving in water from a particular batch is a certain value. That value o f solubility is probably not pertinent to another batch unless the chemical composition o f the second batch is identical to the first. This is particularly im portant in die case o f determining solubility of surface active substances because anionic surfactants which may be near their K rafft points in a particular solubility experiment w ill show substantial changes in solubility w ith tem perature, chain length, isomeric structure, and counter-ion (e .g ., lithium , sodium or potassium). The procedures used in the current report are really not adequate for solubility determination. In general, a number o f solutions o f differing concentrations should be prepared and analyzed after equilibration. The approach to equilibrium should be done in both directions, i.e ., from lower and higher temperatures to the temperature o f interest. The solubility result from this report is in agreement with the result (1 .0 8 g/1) for FC-95 from Env. Lab. Request No. 5372S o f Dec. 2, 1980. However, no higher concentration mixtures o f FC-95 ( than 0.25% ) with water were attempted and this is a defect o f the report. There is a disturbing suggestion in the report that the "solubility" may be a function o f the quantity o f FC-95 mixed w ith water (see p. 2, Introduction, text following "The Commercial C hem icals. . . " . If solubility is to mean anything, one should get the same value with differing amounts o f solid phase present. Edwin E. Tucker, Ph.

' Replicate laboratory measurements showed, the water solubility of FC-95, Lot 583, to be 1.08 g/1 at 22.5C. The procedure for determining this solubility involves stirring 2.5 grams of -FC-95 in deionized water for 24 hours, settling for 1 hour, and filtering through a 0.45 ul membrane filter or filtering through a 0.7 ul glass-fiber filter or centrifuging at 12,000 x G for 10 minutes. TOC measurements on the saturated solutions developed by all 3 of the above procedures varied from each other by <1%. The complete solubility of FC-95 at 0.25 g/1 demonstrated that saturation and not the presence of insoluble components caused the incomplete dissolution of FC-95 with 2.5 g/1 mixtures. Information Liaison W\c1 000154 Solu. Meas. FC-95 - EAR/WAS Page 2 February 16, 1981 INTRODUCTION This project, to measure the water solubility of commercial FC-95, was undertaken because of large discrepancies that existed between measurements made by the Environmental Laboratory and by Commercial Chemicals Laboratory. The Environmental Laboratory had used the Veith techniqued) for saturating water with organic materials. The saturation procedure utilized radio-labeled FC-95 and saturated the solution by recycling water through an FC-95 coated column for 48 hours prior to determining a concentration of 286 mg/1 b y scintillation counting(2). The Commercial Chemicals reported solubility value for FC-95 is 1 gram per 100 grams of distilled water, which is 35 times the previous Environmental Laboratory's measured concentration. CCD's procedure, however, involved mixing very large quantities of the Commercial FC-95 with water and may have selectively dissolved very soluble components of FC-95. \ The present study measures the water solubility of FC-95 using water-product mixture levels that are near the saturation level, and thus should eliminate the possible error in the Commercial Chemicals' technique. METHODS AND MATERIALS The measurements utilized FC-95, Lot 583. Test mixture concentrations were 2.5 grams and 0.25 grams per liter. Mixing took place in a 20+lC incubator, using 1 1/2" Teflon-coated magnetic stirring bars and magnetic stirrers. Styrofoam sheeting separated and insulated the bottles' containing the test mixtures from the heat generated by the magnetic stirring boxes. At the end of the stirring period (24 hours), the temperature of the test solutions were 22.6C for the 2.5 g/1 mixture and 23.2C for the 0.25 g/1 mixture, indicating incomplete insulation. Following mixing, the mixtures settled for 1 hour prior to pipetting off the supernatants and their division into 3 aliquots. Three separate procedures, performed in parallel, insured complete clarification of the supernatant. These included: 1) filtration of one of the 3 aliquots from each mixture through a 0.7 urn glass-fiber filter, 2) filtration through a .45 um millipore membrane filter Type HA, and 3) centri fugation at 10,000 rpm (approx. 12,000 x G) at 20C for 10 minutes Solub. Meas. FC-95 - EAR/WAS Page 3 February 16, 1981 TOC measurement provided the data for the calculation of the FC-95 concentrations in the filtrates and supernatants. Boiling the millipore filters 3 times for 1 hour and washing the glass-fiber filters thoroughly with distilled water before filtering insured that the filters did not add organic material (TOC) to the filtrate. The calculation of the FC-95 concentrations assumed a TOC of 17.8%. This is the theoretical TOC and is also the TOC we have measured in our laboratory analysis of FC-95. RESULTS AND DISCUSSION Table 1 shows the results of the dissolved TOC (DOC) measurements and the corresponding FC-95 concentrations. The data shows that at .25 g/1, FC-95 is completed dissolved. This indicates that there are no very insoluble components of FC-95. At 2.5 g/1, only approximately 1 g/1 is dissolved. This identical result was obtained using all three clarification procedures. In addition, as a quality assurance test, TOC measurements were made on potassium hydrogen phthalate solutions of known concentration (Table 2). These controls demonstrated the accuracy of our TOC procedure. REFERENCES (1) G. D. Veith and V. M. Comstock, J. Fish. Res. Board Can. 3 2 , 1848 (1975).

The following is abbreviated due to the fact that this study has been superceded by a more recent test. METHOD Method: Procedure developed by 3M Company GLP (Y/N): No Year (study performed): 1982 Remarks field: The two samples submitted for testing were duplicate filtrates of a mixture of the test substance dispersed in water at a concentration of 0.25%. Undissolved material was noted in the mixtures. The mixtures were stored in an incubator at 20 + 1C from 11 -24-80 until filtered through a Whatman glass fiber filter prior to TOC analysis on 6/16/82. RESULTS Values using the TOC Analyzer DC-80: Sample 1: 9ppm TC Sample 2: 9ppm TC Values using the TOC Analyzer DC-52 High Temperature (800C) method: Sample 1: 195 ppm TC Sample 2: 195 ppm TC Remarks: Results for the DC-80 UV-Persulfate Analyzer indicated there was no breakdown of the C-F bond, so it was determined that this was an unacceptable method. It is noted that the test author felt the DC52 analysis was accurate. Therefore using the molecular weight of Perfluorooctanesulfonate (538), a solubility of 1090 mg/L can be calculated. Description of solubility (e.g., miscible to soluble to not soluble): Slightly soluble. 000167 DATA QUALITY Reliability: Klimisch ranking = 3. This study does not meet criteria for quality testing.

The results are summarized In the attached Application Report. As we discussed over the telephone, your perfluoronated organic samples were analyzed for Total Carbon using two TOC methods: the DC-80 UV-Persulfate Analyzer and the DC-52 High Temperature Analyzer. It is apparent from the results that the UV-Persulfate Oxidation does' not breakdown the C-F bond so it is not an acceptable method. Since you already have a DC-52 but need to analyze for trace carbon, I suggest that you push it to its lowest detection limit possible by using the TC mode and keeping the system very clean.
