Michigan), Manitowoc River (Wisconsin) and the Kewaunee River (Wisconsin). The fifth sample Isa human biopsy fat specimen. All samples are estimated to conta1n ppm levels of PCBs along with other chlor1nated hydrocarbons (DDT, DDD, DDE, BHC, and Dleldren). An effluent sample taken from the fifth settl1ng pond at the ffcMC Central Foundry Division was analyzed for PCBs. The effluent con tained about 10 ppm of apparent PCBs which were not identical to either Aroclor 1242 or Aroclor 1248 but 11ke a mixture of the two. The alteratlon of the electron capture chromatogram could be due to the use of 1 248 as make up 1n reclaimed 312, some biological a 1tera tlon of 1242, or the presence of other electron capturing materlals In the sample. It was suggested that more samples be examined. The initial bioloqijcaXl^-jcLPPul ated river water (Meramec River) degradation study of Aroc 1 ors 1221, 1 1248, and r2F4~1ras been completed. The results 1 ndicjut&d_ that only Aroclor 1221 was significantly degraded. Aroclors 1242, 1 24B, and 1254 we?e unaffected af t~ar ah' exp.O.$unIIperjodMr^atizwswkb . A rgp^TT~wTl 1 be Issue i. The semi-continuous activated sludge degradation studies carried out 1n St. Louis confirm the river water results in that the major isomers 1n Aroclor 1221 were readily degraded. Additionally, some slight degradation of the 1ower chiorlnated Isomers In Aroclors 1242 and 1248 was observed. The Aroclor 1221 and 1248 exposures have been dis continued to free two of the four semi-continuous units, being operated, to study the^effect of biphenyl accumulation on the degradatlon of Aroclor 1 242 and theTegraclatioh'of Arobrom 1228, a potentla 1 Aroclor substitute-. ..... "" The appl1cabi11ty of extending the analytical techniques developed to monitor Aroclors, Bromo Aroclor 1242, Arobrom 1228, and tri-tetra chlorobenzenes has been established. Only siight mod1f1 cations are -- necessary. Samples of Bromo Aroclor 1242, Arobrom 1228, and two blends of Aroclor 1142 have been sent to Ruabon, U.K., for biodegradation studies. Plans have been made to determine the feasibility of incineration as a means of disposing of non-reclaImable Aroclor and Aroclor containing waste. Three materials, Aroclor 1242, waste Intereen, and Aroclor 1260, wl11 be tested at 1600F, and 2000CF. The tests will be carried out by John Zink Company In Tulsa, Oklahoma on March 10th. Provisions have been made to sample the stack gases for PCBs. -- A discussion on the analysis of sediment and wa'ter samples for PCBs was held wlth W.G.K. personnel to determine If the plant 1aboratory cou1d take over this function. Support analysis of W.G.K. plant samples will be continued until they are set up and prepared to do their own analysis. ' ' COMPANY TRAN 021706 CONFIDENTIAL HARTOLDMON0027113 The Anniston plant analytical laboratory Is currently in the process of setting up the equ1pment to do their own PCB analysis. In support of this, one man week'was spent In St. Louis familiar izing Don Turner, who will be doing the analysis at Anniston, wi th the analytical methods and equipment. Yellow crystallIne solid recovered from W.G.K. process top oil scum was shown by IR to be an 1norganic compound, probably a metal halide. No chlorinated biphenyls or chlorinated terphenyls were detected. GC support was given to the laboratory reformulation of distillation cuts of Aroclor 1130 1n an attempt to produce biodegradable species. SKYDROL 500 IR analysis of hydraulic fluids from two Pan American test flights of Skydrol 500C showed that both were grossly admixed with Oronite Hi jet fluid. A/C 320 conta1ned 10-12$ Hi jet and A/C 321 contained 25-30$ Hi jet. Deposits in the brake system of an Eastern Airlines DC-9 are due to a s11icone polymer and not decomposltlon products of Skydrol 500. IR Snaiysls of solids recovered by fi1tration of the fluid through a 1 /j mi 111 pore f 11 ter and deposl ts from the valve and f 11 ter showed that only a silicone polymer was present. The solids from the right hydraulic system also contained an inorganic carbonate. Skydrol 500 decomposition products were not detected. Identification of FC-98, a purchased additive, was made for pa tent coverage. IR Indicates it is a perf 1 uori nated sulfonate- sal t con taining no hydrogen. Atomic absorption Indicates the princ1 pa 1 metal present is potassium (6.2$). A hydrolyzed portion of FC-98 was analyzed by mass spectrometry using the heated solids probe inlet. The major component appears to be a cycl1c perf1uorosulfonic acid with a molecular weight greater than 400. A BAC 111 feel valve spool in a system using Skydrol 500 A/B developed a white depos11. IR shows 11 to be a hydrated inorganic metal phosphate salt which 1s water soluble. ' Deposit from a Braniff BAC 1-11 aircraft f11 ter bowl was shown by IR to be an inorganic^metal phosphate. The dielectric strength, power factor, dielectric constant, and AC resistivity of Skydrol 500C (Lot QL-2) and Skydrol LD were measured at 25 and 100"C as a customer service for Lockheed. THERMINOL 66 A. Gross and Company reported a 1ow bolling liquid 1n their Therminol 66 systern. As an aid to determining the source of this liquid, a catch tank sample was characterized by GC/MS.
