Abstract |
A total of 198 samples of runoff and Arkansas River water were collected in the metropolitan area of Tulsa, Oklahoma, and analyzed for chlorinated hydrocarbon pesticides from March 1970 through June 1972. Sampling at 15 different sites was conducted in three phases: Arkansas River water above and below the metropolitan area; storm drainage basins at maintenance flow; and storm-water runoff. Pesticides identified entering the river from drainage basin outfalls at some time during the project include lindane, heptachlor, heptachlor epoxide, aldrin, and dieldrin. A supplementary investigation of heavy metals in storm-water runoff identified lead and chromium entering the Arkansas River from drainage basin outfalls. (Modified author abstract) |
