Abstract

Movement of alachlor, atrazine, cyanazine, deethylatrazine, deisopropylatrazine, and metolachlor between surface water and ground water in documented data collected from May 1989 through July 1991 at a study site in the lower Cedar River basin, Iowa. The principal source of atrazine, deethylatrazine, deisopropylatrazine, and metolachlor in the Cedar River during two periods of base flow in 1989 and 1990 was ground water discharged from the alluvial aquifer adjacent to the river.
