Local Water, Local Control
Governments throughout the world are trying to improve the performance of publicly-owned and operated irrigation districts by turning operation and management of the districts over to...
Pilot-scale Anaerobic Biological Removal of Selenium from Agricultural Drainage Water Using Sequencing Batch Reactors
Effects of Drainage on Water, Sediment and Biota
The U.S. Department of the Interior started a program in 1985 to identify effects of irrigation-induced trace constituents in water, bottom sediment and biota. The program was developed...
Evaluation of Conjunctive Use and Drainage Reduction Strategies
Optimal drainage management strategies for control of salt and selenium contamination problems in the San Joaquin Valley of California must recognize subregional differences in groundwater...
Stochastic Modeling of Water Quality in the San Joaquin River, California, Using Monte Carlo Simulation
Anaerobic Biological Reduction of Selenate
When soils with high concentrations of naturally-occuring selenium are irrigated and drained, selenium is leached from the soil and appears in the drainage water. Selenium has caused death...
Selenium in the Kendrick Reclamation Project, Wyoming
Elevated concentrations of selenium in water, bottom sediment, and biota were noted during a reconnaissance investigation of the Kendrick Reclamation Project in central Wyoming. Dissolved-selenium...
Irrigation Drainage: Green River Basin, Utah
A reconnaissance of wildlife areas in the middle Green River basin of Utah during 1986-87 determined that concentrations of selenium in water and biological tissues were potentially harmful...
Geohydrologic Aspects of Water-Quality Problems of the San Joaquin Valley, California
Salinity and selenium concentrations in shallow ground water of the western San Joaquin Valley, California, are related to the geomorphology and hydrology of the alluvial fans. High salinity...
Trace Elements and Pesticides in Salton Sea Area, California
Concentrations of numerous potentially toxic trace elements and pesticides were determined in water, sediment, and biota from the Salton Sea area in southestern California. Comparison...
Selenium Threatens Irrigators, Wildlife
Irrigation drainage water has seldom been treated to remove pollutants, but it soon will be treated in California. Drainage from a large portion of the San Joaquin Valley must be treated...
Selenium Removal?Can We Afford It?
The process of biologically removing the element selenium from agricultural drainage water is discussed and an economic evaluation of the process is presented. If by-products can be recovered,...
Selenium: Essential Nutrient or Toxic Threat?
The essential nutrient selenium is believed responsible for numerous deformities, reproductive failures, and deaths of migratory birds at Kesterson Reservoir in the San Joaquin Valley,...
Selenium: It's Not Just in California
The U. S. Department of the Interior has embarked on a series of reconnaissance level investigations throughout the western states to identify and assess potential irrigation-induced water...
Selenium Cleanup Slated for Refuge
The Local Perspective on Agricultural Drainage
This paper discusses shallow, perched groundwater and resulting agricultural drainage and salt problems that have developed in the San Joaquin Valley of California over the past 30 years....
