A University of Utah geography professor, Leroy H. Wullstein, has been appointed to the State Water Pollution Control Committee.

The committee, which is responsible for maintaining the quality of water sources throughout Utah, has 10 members and meets six times each year. Wullstein's appointment was recommended by Gov. Norm Bangerter and approved by the Utah Legislature.Wullstein will represent wildlife and environmental interests during the yearlong term. He said the most pressing environmental issue of this decade is pollution "at the water's edge."

For example, overgrazing causes soil erosion, and soil washes into streams. Chemicals used as fertilizers can end up in rivers, harming water quality.

In addition to his post at the university, he is director of riparian concerns for the Utah Wildlife Leadership Coalition. The coalition includes conservation, hunting and fishing groups.
