Selenium mass balance in the Great Salt Lake, Utah

2009-3-15  A mass balance for selenium was developed for the period May 2006 to July 2007, during which data regarding inputs and outputs to the lake were collected ().Aqueous chemical conditions were characterized in the field at four locations (2267, 2565, 2767 and 3510) across the main body of the Great Salt Lake and at 7 to 13 depths (varying by station), ranging from 0.2 to 8 m depth below lake

Selenium mass balance in the Great Salt Lake, Utah

A mass balance for Se in the south arm of the Great Salt Lake was developed for September 2006 to August 2007 of monitoring for Se loads and removal flows. The combined removal flows (sedimentation and volatilization) totaled to a geometric mean value of 2079??kg Se/yr, with the estimated low value being 1255??kg Se/yr, and an estimated high value of 3143??kg Se/yr at the 68% confidence level.

2020-6-11  The Great Salt Lake is the fourth largest terminal lake worldwide ( Stephens, 1990 ) and the largest saline lake in North America ( Brix et al., 2004 ). The lake is shallow (maximum depth is around 9 m) with a vast surface area that varies considerably depending on its surface elevation ( Baskin, 2005 ).

Correlations with SC used to convert SC to Se or U concentrations (Figures S1 and S2; Table S2) are not as tight as those for TDS (Table 1). Correlations between SC and U are quite strong, with R 2 values ranging 0.81–0.96.

Selenium Treatment / Removal Alternatives Demonstration

Ground- water formerly surfaced from two main sources within the site into a large wet- lands area on the boundary of the Great Salt Lake. Selenium contaminated ar- tesian flow is currently captured and routed into KUCC's process water cir- cuit. The contamination is of a low-level, high-volume nature that makes most treatment options expensive.

Assessing the toxic threat of selenium to fish and aquatic

A procedure is given for evaluating the toxic threat of selenium to fish and wildlife. Toxic threat is expressed as hazard, and is based on the potential for food-chain bioaccumulation and reproductive impairment in fish and aquatic birds, which are the most sensitive biological responses for estimating ecosystem-level impacts of selenium contamination. Five degrees of hazard are possible
