Abstract : During the summer of 1988, UCLA conducted a field experiment on flushing of organic contaminants from a contaminated aquifer in the western tier of RMA. The objective 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 on water flow and TRCLE and 111TCE flashing rates; (4) Compare results of field and laboratory investigations. The laboratory analyses 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 extracted water, (2) spiking it with a TRACER, and (3) Reinjecting it. The field data show that flushing will be very efficient in the highly permeable strata,
