Book excerpt: Jan van Schilfgaarde, USDA Agricultural Research Service and National Research Council Committee on Irrigation-Induced Water Quality Problems In 1982, a startling discovery was made. Many waterbirds in Kesterson National Wildlife Refuge were dying or suffering reproductive failure. Located in the San Joaquin Valley (Valley) of California, the Kesterson Reservoir (Kesterson) was used to store agricultural drainage water and it was soon determined that the probable cause of the damage to wildlife was high concen trations of selenium, derived from the water and water organisms in the reservoir. This discovery drastically changed numerous aspects of water management in California, and especially affected irrigated agriculture. In fact, the repercussions spilled over to much of the Western United States. For a century, water development for irrigation has been a religiously pursued means for economic development of the West. The primary objective of the Reclamation Act of 1902 was, purportedly, the development ofirrigation water to support family farms which, in turn, would enhance the regional economy (Worster, 1985).

This book was released on 1987 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: Kesterson Reservoir (Kesterson) received subsurface agricultural drainwater containing high levels of salts and other minerals from farmland in the San Joaquin Valley of California. Aquatic plants and invertebrates were sampled at Kesterson in May, August, and December of 1984. The reservoir supported a different biota and lower species diversity than a nearby control site (Volta WMA). Kesterson had a greater plant and seed biomass while Volta had a greater invertebrate abundance. Submergent habitat at Kesterson was dominated by widgeongrass (Ruppia maritima) while Volta was dominated by horned pondweed (Zannichellia palustris). Several aquatic invertebrates, including Amphipoda, Exlais, Gastropoda, Neomysis, Hirundinea, and Belostomatidae were common at Volta but were never observed at Kesterson. Kesterson supported a greater abundance of diatoms (Nitzschia), Oligochaeta, Ephydridae, Stratiomyidae, Tabanidae, and Syrphidae while these were rarely encountered at Volta. Community structure at Kesterson was most likely influenced by high concentrations of salts, nitrogen, boron, and possibly selenium. Bioaccumulation of selenium and other trace elements in wetlands and waterfowl foods at Kesterson was investigated during May, August, and December of 1984. High concentrations of selenium were found in water, sediments, terrestrial and aquatic vegetation, and aquatic insects. Selenium concentrations in aquatic plants and insects ranged from 2 to 310 ppm and were about 10 to 290 times those found at Volta. Concentrations in waterfowl food plants and insects at Kesterson were as high as 64 times greater than those reported to be a health hazard to birds. Seasonal variations in selenium concentrations were observed in some plants, but few consistent seasonal patterns were observed in aquatic insects, and few differences in selenium accumulation were found among ponds. Distribution of selenium in plant parts was not uniform during a growing season, as rhizomes contained higher concentrations than seeds. Most biota bioaccumulated selenium to levels greater than 1000 times the concentration in water, some nearly 5000 times. Mean concentrations of boron in aquatic plants and insects were usually 2 to 52 times those at Volta. Concentrations of other trace elements (i.e. arsenic, cadmium, chromium, copper, lead, mercury, molybdenum, and nickel) at Kesterson were too low to be toxic to biota.

Department of the Interior and published by Forgotten Books. This book was released on 2016-08-20 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Preliminary Planning Alternatives for Solving Agricultural Drainage and Drainage-Related Problems in the San Joaquin Valley: Executive Summary Drainage Program is in the process of developing additional alternatives to meet both short and long-term needs. In 1987, the Drainage Program narrowed its focus on planning alternatives to measures that could be taken to address the agricultural drainage and related problems within the San Joaquin Valley itself. This decision reflected the need to control conditions and manage problems as close to their source as possible, and to help ensure that areas outside the valley are not adversely affected by the problems or measures to solve them.

Book excerpt: Excerpt from Preliminary Planning Alternatives for Solving Agricultural Drainage and Drainage-Related Problems in the San Joaquin Valley: August, 1989 Current agricultural drainage conditions on the west side of the San Joaquin Valley present two basic problems: (1) Salt buildup and waterlogging of irrigated lands due to a high ground-water table, which adversely affects crops and productivity, and (2) toxic or potentially toxic trace elements in the shallow ground water, which when drained and discharged to streams, ponds, or wetlands, can adversely affect fish and wildlife.
