Abstract : During the summer of 1986, UCLA conducted a field experiment on flushing organic contaminents from a contaminated aquifer in the western tier of RMA. The objectives of the study were to: (1) Estimate the hydraulic conductivity of the aquifer: (2) Estimate the degree to which TRCLE and 111TCE are retarded in their mobility due to sorption by the aquifer media: (3) Determine the effects of spatial variability of aquifer properties water flow and TRCLE and 111TCE flushing rates: (4) Compare results of field and laboratory investigations. The laboratory analysed of coring samples indicated that both the hydraulic conductivity of the aquifer and the TRCLE mobility are likely to vary significantly with depth. The field experiment consisted of (1) air stripping significantly extracted water, (2) spiking it with a tracer, and (3) reinjectintg it. The field data show that flushing will be very efficient in the highly permeable strata.
