Years of Scientific Accomplishments in Menlo Park The Bureau of Reclamation is re-evaluating options for providing drainage service to the San Luis Unit of the Central Valley Project. The EIS evaluates seven action alternatives in addition to No Action: In-Valley Disposal, In-Valley/Groundwater Quality Land Retirement, In-Valley/Water Needs Land Retirement, In-Valley/Drainage-Impaired Area Land Retirement, Ocean Disposal, Delta-Chipps Island Disposal, and Delta-Carquinez Strait Disposal. All of the alternatives would include common elements: on-farm and in-district actions, drainwater collection systems, regional reuse facilities, the Firebaugh sumps, and land retirement of at least 44,106 acres. In addition to the common elements, the action alternatives (except Ocean Disposal) involve varying levels of drainwater treatment (reverse osmosis and/or biological selenium treatment) and/or additional land retirement before disposal. http://www.usbr.gov/mp/sccao/sld/ The Grassland Bypass
Project (GBP) is based upon an agreement between the U.S. Bureau
of The western San Joaquin Valley is one of the most productive farming
areas in the United States, but salt-buildup in soils and shallow
groundwater aquifers threatens this area’s productivity. Elevated selenium
concentrations in soils and groundwater complicate drainage management and
salt disposal. In this document, we evaluate constraints on drainage
management and implications of various approaches to management considered

The
Pacific Institute and the U.S. Geological Survey’s Salton
Sea Science Office convened a workshop in November 2004 to evaluate
a proposal to rehabilitate the Salton Sea. The associated report,
compiled and edited by the Pacific Institute under contract to the
Bureau of Reclamation, presents the conclusions generated by the
workshop. The report
states that, in general, the presence of selenium is a concern because

San Diego Creek/Newport Bay Toxics TMDL
On June 14, 2002, the U.S. Environmental Protection Agency (EPA) established the Toxics TMDL for San Diego Creek/Newport Bay. The EPA promulgated TMDL covers 14 different constituents – chlorpyrifos and diazinon (organophosphate pesticides); chlordane, dieldrin, DDT, PCBs, and toxaphene (organochlorinated compounds); cadmium, copper, lead and zinc (metals); selenium; chromium and mercury (metals, specific to Rhine Channel only). http://www.ocwatersheds.com/watersheds/tmdls_toxics_intro.asp |

U.S. Geological Survey
Utah Water Science Center Working
with a stakeholder committee, Utah's Division of Water Quality
has began a process to establish numeric standards for the Great
Salt Lake. The initial focus will be on selenium. Public concern
over the potential of adding more selenium to the Lake as the
result of the South West Jordan Valley groundwater cleanup project
brought a renewed focus on the need for numeric standards. Under
the committee’s oversight, a science panel will look at
the existing selenium studies on the Lake and conduct additional
work, where necessary. The committee will consider the science
panel’s work, then make a recommendation to the Water Quality
Board. If the Board accepts the recommendation, the standard will
be sent out for public comment before the action is final.
Great Salt Lake Selenium Standard, Written Recommendation to the Steering Committee, by Joseph Skorupa, U.S. Fish & Wildlife Service. These points are covered in the following article:

A related issue to that of selenium in the Great Salt Lake is
the elevated concentrations of mercury found in ducks in December,
2005. The Utah Division of Wildlife Resources (UDWR) began a preliminary
study during the summer of 2005 to determine if ducks around Great
Salt Lake contained mercury. This concern was based upon research
findings from the United States Geological Survey (USGS) and United
States Fish & Wildlife Service (USF&WS) that demonstrated
the lake had elevated levels of methyl mercury. Archived tissue
samples from three waterfowl species were taken from ducks collected
in 2004 in an unrelated study being conducted by The Great Salt
Lake Ecosystem Project at UDWR and Utah State University (USU).
