Kesterson Reservoir (Kesterson) received subsurface agricultural drainwater containing high levels of salts and selenium from farmland in the San Joaquin Valley of California. The accumulation of selenium in wetlands and waterfowl foods at Kesterson was investigated during May, August, and December of High concentrations of selenium were found in water, sediments, terrestrial and aquatic. Selenium and the Kesterson Reservoir Kayla Carpenter San Luis Drain Built by Bureau of Reclamation Originally from Five Points, CA, to Bay Reservoir = controlling reservoir, midpoint SELENIUM! & water extractable Se Plant roots can take up Se from lower soil profile good news for aquifer Food chain contamination less with upland.
By , almost all of the water entering Kesterson Reservoir was agricultural drainage from poorly drained soils. Mosquitofish collected by the U.S. Fish and Wildlife Service in the early s from Kesterson Reservoir contained levels of selenium approximately times higher than mosquitofish found in neighboring wetlands not receiving Cited by: 2. Selenium Toxicity at Kesterson Reservoir. Selenium is an element that has similarities with sulfur. It is widely distributed in soils, rocks, and water. In small amounts it is a nutrient, in large amounts, a toxin. It might achieve its toxic effect through its ability to replace sulfur in proteins.

In the original plan, the Kesterson site was supposed to be a regulating reservoir for the drainage water on its way from the Westlands area and other west side districts north to the Delta. Due to financing difficulties and environmental objections to possible pesticide contamination in the Delta, the so-called "Master Drain" was never.

Agricultural drainage problems and contamination at Kesterson Reservoir: hearing before the Subcommittee on Water and Power Resources of the Committee on Interior and Insular Affairs, House of Representatives, Ninety-ninth Congress, first session on agricultural drainage problems and contamination at Kesterson Reservoir, hearing held in Los Banos, CA, Ma The Kesterson Reservoir is the name of a former unit of the Kesterson National Wildlife Refuge which is part of the current San Luis National Wildlife site gained national attention during the latter half of the 20th century due to selenium toxicity and rapid die off of migratory waterfowl, fish, insects, plants and algae within the Kesterson Reservoir.

Editors' Summary: In Kesterson National Wildlife Refuge in central California achieved national prominence when Fish and Wildlife Service scientists discovered severely deformed and dead waterfowl at the refuge and concluded that the cause was selenium contamination from.
Shallow groundwater under Kesterson Reservoir, Merced County, California, was contaminated over a period of 6 years while the reservoir was used for disposal of brackish subsurface agricultural drainage water from farmlands in the San Joaquin Valley.
Drainage water contained an average of 10, mg. 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.

Subsurface agricultural drainage waters from western San Joaquin Valley, California, were found to contain elevated concentrations of the element selenium in the form of selenate. Inthese drainage waters began to replace previous input to Kesterson Reservoir, a pond system within Kesterson National Wildlife Refuge; this substitution was.
Hypothesized to be derived from Cretaceous marine sedimentary rocks, selenium contamination of the Kesterson National Wildlife Refuge is traced through irrigation drainage to the source bedrock of the California Coast Ranges.
This biogeochemical pathway of selenium is defined here as the “Kesterson effect.” At the refuge ponds, this effect culminated in in a 64% rate of Cited by: Inthese drainage waters began to replace previous input to Kesterson Reservoir, a pond system within Kesterson National Wildlife Refuge; this substitution was completed by In the The Se (IV) from the coal ash and Se(VI) from the agricultural drainage lead to the notorious Se contamination incidents in the Belews Lake and Kesterson Reservoir, respectively (Schwartz et al.
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 Cited by: Full text of "Agricultural drainage water contamination in the San Joaquin Valley: public health perspective for selenium, boron, and molybdenum" See other formats.
the flows discharged into Kesterson Reservoir were composed of subsurface drainage generated by acres of irrigated agricultural lands in the Westlands Water District of the San Luis Unit (9).
In 1, samples of water from the Drain and Kesterson Reservoir were found to contain high salinity and elevated concentrations of selenium. The sources and biogeochemistry of selenium (Se) combine to produce a widespread potential for ecological risk (Figure 1). Documented environmental effects across scientifically investigated sites include deformities in birds and fish, degraded fish communities, and exclusion of habitats for bird use (see Modeling and Irrigation pages).
The large geologic extent of Se sources is connected by. The order to close Kesterson Reservoir came inbut the problems of managing and disposing of contaminated agricultural drainage are far from solved and pose a continuing threat to biological resources in the San Joaquin Valley.
Agricultural drainage problems and contamination at Kesterson Reservoir: hearing before the Subcommittee on Water and Power Resources of the Committee on Interior and Insular Affairs, House of Representatives, Ninety-ninth Congress, first session hearing held in Los Banos, CA, Ma Monthly Maximum Discharge Limits (MMDL) have been established for selenium in irrigation drainage by the State of California and the U.S.

As a result of. Following the discoveries of irrigation drainage-related contamination issues at Kesterson Reservoir, the US Department of the Interior (DOI) implemented the National Irrigation Water Quality Program (NIWQP) in to study the effects of irrigation drainage on water resources and on fish and wildlife (Deason,Seiler et al., ).

The pollution may come from a variety of sources, ranging from point source water pollution (from a single discharge point) to more diffuse, landscape-level.
