Principle considerations in examining water-management options for the control of toxic trace elements in agricultural drainage waters are addressed, including a number of improvements in off-farm water delivery systems, as well as efficiency of on-farm irrigation systems and water reuse. Potentials exist to improve off-farm water-delivery systems through reductions in seepage losses with canal linings, operational spills through systems irrigation scheduling, and interception of water losses and reuse. Potentials also exist in improving on-farm water management through improved irrigation application systems, on-farm irrigation scheduling, and other cultural products such as changes in cropping patterns. These on-farm management options will effect net farm income due to increased costs of equipment and structures, increased labor requirements, and changes in crop revenue. But not all of these will have a negative economic input. For instance, efficient irrigation systems not only value drainage but tend to increase crop yield or decrease crop production inputs. Installation of structural system improvements and use of system scheduling of water delivery may result in decrease in operation and maintenance costs. Institutional and legal constraints, particularly water-right ownership, may constrain efforts to minimize drain-water production and toxic-element problems. The long-term economic viability of irrigated agriculture will require careful consideration of both off-farm and on-farm management options.

Concern over potentially toxic effects of trace elements in agricultural drainage waters has been aroused by the discovery of selenium poisoning of wildlife at Kesterson Reservoir, California, and was heightened further through discovery of elevated levels of selenium in shallow ground water underlying extensive areas of San Joaquin Valley's west side. Recent investigations by the US. Department of the Interior's National Irrigation Water Quality Program (NIWQP) revealed that similar trace-element problems exist in several other western states including Nevada, Utah, Wyoming, and Colorado, as well as the Tulare Lake Bed and Salton Sea in California. Management options assessed for trace elements discharged from irrigated lands include source control, drain-water reuse, drain-water treatment, and removal of contaminants, disposal, and institutional and jurisdictional control measures. A combination of source control and other drainage-water-management options has the potential to reduce the toxic-element problem. An initial prognosis indicates that a status quo scenario will be unacceptable to the public. Agriculture will be increasingly challenged in its use of water and land resources and perceived impacts on the quality of the environment. The effect of drainage reduction and other management options on reducing the discharge of trace elements is, to some extent, influenced by site-specific conditions. The economic viability of agriculture will be severely tested in the most severely trace-element-impacted lands, water, and biota, and this may lead to changes in land use.
