Response to Selenium
Concern
n In response to the selenium concern, DWQ
recognized the need to develop numerical standards
to protect the beneficial uses of the GSL
n The proposing parties recognized the need to
involve interested parties to address the questions
about selenium fate and transport
n Establish the Great Salt Lake Water Quality Steering
Committee to study the water quality of the Lake
and make recommendations to the Division of Water
Quality regarding a numeric water quality standard
for Selenium for the open waters of the Lake
The Road to Developing a Se
Standard for the GSL
n Preliminary discussions were held in
March 2004 with the FGSL to define a
process
n April – July 2004: Work Group
recommends a Steering Committee be
established and a Science Panel be
selected
n August 2004: 1 st meeting

Miscellaneous
n The goal is to have the Steering Committee
make a recommendation for a Selenium
standard to DWQ by December 2007
n Local, state and federal funds are pledged to
this effort
n The Steering Committee may be maintained
to develop other standards for the GSL

Science Panel Meeting
March 16, 2005
n Motion: Develop a Conceptual Model of the “flow”
of Selenium in the Ecosystem
n Qualitative analysis of where the selenium moves
n Graphical representation
n Framework to determine what is needed for the future
n Utilize funds (< $20,000) to put together this model
n Important considerations: Skills, Costs, Timing
Sampling Round Robin
Purposes:
• Determine the best analytical method for the
GSL matrix
• Determine the best achievable detection limit
• Determine the variance between the
laboratories participating
• Determine the best laboratory for future work
