Chloride at the Bayou Creek downstream location was higher than at the upstream site. The highest concentrations of suspended solids and iron were found in the Ohio River. Uranium was also detected at low concentrations in all downstream creek locations. o 3KM o 1 ~MW ~ SOmpIJng A*II .

The results for the receiving creeks can be compared t~ the Paducah Site's KPDES permit standards which are based on warm water aquatic habitat criteria established by KDOW (401 KAR 5:031). All sample results for Bayou and Little Bayou creeks are within KPDES standards. Surface water samples are also taken on a quarterly basis at the C-746-S&T closed landfills. Samples are taken upstream of surface runoff from the . landfill, at the landfill, and downstream of the landfill. Data is reported quarterly to KDWM.. Appendix C provides the results of surface water monitoring. Figure 8.1 shows monitoring locations. Additional ~urface water data can be found in Appendix C. Sediment , I' t , Surface Water Surveillance Results Table 8.1 shows average concentrations for parameters where upstream and downstream results differed noticeably. Only one sample of the eight samples collected had a detectable concentration of acetone. L 12 and L 241 had TCE concentrations of 4 mg/L and 34 mg/L, respectively. These stations are located in Little Bayou Creek downstream of L 10 (Figure 8.1). Recharge of the creek from the Northeast Groundwater Plume is believed to be responsible Sediment is an important constituent of the aquatic environment. If a pollutant is a suspended solid or is attached to suspended sediment, it can settle to the bottom (thus creating the need for sediment sampling), be taken up by certain organisms, or become attached to plant surfaces. Pollutants in solution can adsorb on suspended organic and inorganic solids or be assimilated by plants and animals. Suspended solids, dead biota, and excreta settle to the bottom and become part of the organic substrata that support the bottom-dwelling community of organisms.
