The Utah Division of Water Quality has begun a long-term project to set new pollution standards for the Great Salt Lake.  The lake contains significant levels of toxic pollutants such as arsenic, lead, selenium and mercury, among other things.  Jeff Ostermiller, the chief of the Water Quality Management Section at the division, says some of that comes from industries surrounding the lake.  But he says there are many other sources as well, including urban runoff from streets along the Wasatch Front.
