Reconnaissance Investigation of Water Quality, Bottom Sediment, and BiotaAssociated with Irrigation Drainage in the Sacramento National Wildlife Refuge Complex, California, 1988-89

摘要

The report describes results of a reconnaissance field investigation of thequality of irrigation drainwater and the effects of its use on five federally managed wildlife refuges in the Sacramento Valley, California. The investigation was designed to determine the magnitude and extent of any water-quality problems that could threaten wildlife and human health. Samples of water, sediment, and biological tissue were collected on or near the refuges and analyzed for selected chemical constituents. The results of the chemical analyses were compared to various standards and criteria, baseline data, and toxicological studies. These comparisons are discussed in the context of the geological, hydrological, and biological systems in the study area.
