Water quality and hydrology

Water quality is a vitally important natural resource in Utah owing to the state’s uneven distribution of precipitation and reliance on clean water for municipal, industrial, and agricultural uses. The mountainous areas of the state receive the majority of precipitation falling as rain and snow while the populated areas in valley bottoms are relatively arid. Water quality is very good in the mountainous areas but tends to decline as it travels downstream due to impacts from a variety of sources including municipal, industrial, agricultural, and natural sources.

The Utah Department of Environmental Quality, Division of Water Quality (DWQ) is responsible for ensuring that pollutants from anthropogenic sources do not impair the designated uses of Utah’s waters.
