Foundation has submitted to us, for mass confirmation, five cleaned up extracts of composite fish samples taken from the Manistee River (Michigan), Burns Ditch (L. Michigan), Manitowoc River (Wisconsin) and the Kewaunee River (Wisconsin). the fifth sample is a human biopsy fat specimen. Al l samples are estimated to contai n ppm 1evels of PCBs al ong wi th other chiorinated hydrocarbons (DDT, DDD, DDE, BHC, and Dieldren). An effluent sample taken from the fifth settling pond at the _ C was analyzed for PCBs. The effluent con tained about 10 ppm of apparent PCBs' which were not identical to either Aroclor 1 242 or Aroclor 1248 but like a mixture of the two. The alteration of the electron capture chromatogram could be due to the use of 1 248 as make up in reel aimed 312, some biological altera tion of 1242, or the presence of other electron capturing materials in the sample. 11 was suggested that more samples be examined. The initial biol ooix-aJ-lv populated river water' (Meramec Ri ver) degradation study of Aroclors 1 221 , 124*21 IZ48, and '12b4 has been completed . The resul ts indiCpa-tad that only Aroclor 1221 was significantly degraded . Aroclors 1 242,.1248, and 1 254 we'Pe unaffected after an exposurePperi od of-~FTg1rt~w-eeki>. A reD0rf~wm be issued. The semi-continuous activated sludge degradation studies carried out in St. Louis confirm the river water results in that the major isomers in Aroclor 1221 were readily degraded. Additionally, some siight degradation of the 1ower chlorinated isomers in Aroclors 1242 and 1248 was observed. The Aroclor 1221 and 1 248 ^exposures have been dis continued to free two of the four semircontinuous units, being operated, to study the^effect of biphenyl accumulation on the degrada tion of Aroclor 1242 and the~ degradation of ArobronTl228, a potential Aroclor 'substitute. ------------ r ~. ! The applicabi1ity of extending the analytical techniques developed I to monitor Aroclors, Bromo Aroclor ' 1 242, Arobrom 1 228, and tri-tetra chi orobenzenes has been establ ished . Only slight modi fixations a re~"~~' necersTry. ----- ' 1 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 feasibi1ity of incineration as a means of disposing of non-reelaimable Aroclor and Aroclor containing waste. Three materials, Aroclor 1242, waste Intereen, and Aroclor 1260, . wi 11 be tested at 1600F, and 2000F. The tests wi11 be carried out 'Vt ! ky John Zink Company in Tulsa, Oklahoma on March 10th. Provisions have been made to sample the stack gases for PCBs. <0^ 0l388 WATER PCB-00054618
