Abstract
The suitability for land treatment of 3 pesticides in a liquid waste stream was evaluated. The evaluation was performed under laboratory conditions utilizing 15 cm by 150 cm long glass columns. Composition of the water was monitored as a function of time and depth for eight columns utilized in the study. Experimental columns were duplicated and there were 4 treatments in the study. Three different soils were studied and one soil was studied at two different hydraulic loading rates. The experimental data were collected in both batch static microcosms and dynamic columns studies. The confidence limits on the batch obtained transformation rates were not sufficiently tight to permit reasonable projections in most cases. The pesticides followed a systematic pattern in the column with respect to transport and degradation. However, apparently processes other than first order take place in the profile and it is necessary to perform additional studies to delineate the actual biochemical processes.
