The decrease in concentration observed Is probably the result of dilution and adsorption of the Aroclor in the original waste water as It moves from the NCR plant to the treatment facilities. However, It is possible lhat the high level of "fresh" Aroclor present has completely masked any degradation that might have occurred to Aroclor previously discharged. db Enclosure E. S.
