tion of analytical techniques2. The results of this study (see
above) indicate that carbon sorption is satisfactory fo~ concen-
trating organic fluo~ochemicals from waters. Further in-depth
studies would have to address recoveries of fluorochemicals from carbon and show no interaction and/or degradation of fluorochemicals on carbon adsorption and desorption. A reliable, less
moisture-sensitive analytical method for FC-95 and FC-807 would
De desirable.

4I)000w)ereacwteitvatseludrry 4000) activated
carbon and shipped to the Decatur, AL, plant (I/30/79). It was
requested that the seven columns be kept refrigerated until use to minimize bbaacctteerriiaall ggrroowwtthh4..
HD 4000 was purified before packing by first ~insing with deionized water (D.I.) and decanting the fines and then rising with methanol followed by D.I. water. The carbon was dried in a
forced draft oven (i10C) and stored in a desiccator until needed.
Sampling at high-volume production (HV) was begun on February, 1979, and low volume (LV) sampling was started on October, 1979, with 1,144 and 623 gallons of effluent sampled respectively. Several backup columns were sampled, but only the HV and LV samples will be discussed in this study.
The carbon, removed from the salnpling columns, was extracted (Soxhlet) for three hours with analytical reagent grade pyridine. Extraction thimbles were not used; silanized glass wool held the carbon in t~e extractor. Thirty grams of clean HD-4000 served as the "blank" in another extraction experiment. The pyridine extracts were filtered through Whatman GFiF paper and the filtrate was Drought to 250 ml with pyridine (analytical solution). Some of this solution was analyzed then for organic aanndd iinnoorrggaanniicc fflluuoorriinnee ((sseeee rreessuullttss))..
Another portion of this analytical solution was concentrated tenfold (rotary evaporator) and the concentraSe was spotted on silica gel TLC plates. They were developed in two dimensions with two different developing liquids. FC-143 and FC-95 were tentatively identified in both the HV and LV samples.
The above concentrate was also analyzed by GC/MS fo~ fluoroc~emicals (see results).
