Abstract

This report contains physical, chemical, and biological data associated with irrigation drainage in the Salton Sea area collected during the late 1980's. The data were collected in support of the u.S. Department of the Interior's National Irrigation Water Quality Program in the Western United States to evaluate effects on the environment from potential toxics in irrigation-induced drainage. The data have been used to support interpretations in several recent publications. This data report is the companion to a comprehensive U.S. Geological Survey interpretive report that describes the geochemical and biological pathways of potential toxics, especially selenium, in the study area. The report contains data on concentra- tions of a broad suite of trace elements in soil, irrigation (Colorado River) water, drainwater, surface water (including the Salton Sea), ground- water, aquatic plants, invertebrates, amphibians, reptiles, fish, birds, bird eggs, and turtle eggs. Included, also, are light stable isotope (hydrogen, oxygen, carbon, nitrogen, and sulfur), tritium, and radiocarbon data for selected aqueous samples and organochlorine-pesticide concentrations in biota. Geochemical samples were collected from more than 100 drainwater-collection sites, several surface- water locations, 15 fields, 3 multiple-depth lysimeter and piezometer installations, and the Alamo River Delta on the southeastern shore of the Salton Sea, and from laboratory evaporations of Colorado River water. Biological samples were collected from 39 sites, including 16 Salton Sea shore locations, 5 streams, 7 freshwater impound- ments, 11 drainwater ditches, and 2 additional locations in the Imperial Valley.
