Fa hh SUMMARY OF C-8 IN WATER SAMPLING PROGRAM This letter summarizes the sampling procedure and the results of the pro- gram to obtain C-8 concentration data for drinking the plant. The original set of samples were taken water down river `from on March 15, 1984. A second set of samples was taken at selected locations on June 4, 1984. The samples were taken by going to gas stations or small grocery stores in communities down stream of the plant and asking to have a plastic jug filled with drinking water. The sample obtained was then transferred to 8 oz. glass bottles. Two bottles were obtained. One bottle was analysis and the second was used as a retainer for future use if used for needed. Tporocfendsuurrea. that the samples were not being contaminated in the sampling Samples were also obtained up river to check for a background or blank and mTohdei ofriicgaitniaoln polfanthweasprtoocedhuarvee tusheed satmopldeesteramnianleyzeC-d8 heirne aiorn. plaTnot gebyt asensitthievitryivberelofwlotw,hea cosnacmeplnetrastiizoenofcal1c0u0lamltedwasforfrdeielzeutidorniedo.f C-T8heemsiusbssieoqnusentby analysis produced high and inconsistent blanks and data. When the analytical problems could not be resolved on plant, the samples were sent to the Experimental Station for analysis by a modification of the C-8 in blood procedure. The details of the analytical procedure are given in the attached letter from S. R. Laas to J. F. Doughty.
