| Study Name | Occurrence and Significance of DDT Compounds and Other Contaminants in Fish, Water and Sediment from the Yakima River Basin |
| EIM Data Entry Review Status | Reviewed |
| Study Type | General environmental study |
| Study Purpose | To determine the concentrations of DDT and other organochlorine compounds in fish and invertebrates from different parts of the Yakima River and evaluate the significance for human health and well-being of aquatic life.
