Kenneth J Leib
Ken is the Associate Director for Studies with the USGS Colorado Water Science Center (COWSC), Western Colorado Office, in Grand Junction, CO.
Previously he served as the Office and Studies Section Chief of the Western Area Office of the COWSC in Grand Junction, CO, and as a project hydrologist. He received a B.S. in Watershed Science from Colorado State University in 1995 and has worked with the USGS since 1996. Ken has served as the COWSC representative to the National Irrigation Water Quality Program, Salinity Control Program, Selenium Management Program, and has been project lead on numerous water-quality and surface water investigations in Western Colorado.

Data summary and loading sources for selected water-quality characteristics of streams in blowdown areas, North Fork Elk River Watershed, Colorado, March 1999-August 2000 Data summary and loading sources for selected water-quality characteristics of streams in blowdown areas, North Fork Elk River Watershed, Colorado, March 1999-August 2000
On October 25, 1997, in and around the Routt National Forest and the Mount Zirkel Wilderness Area, a winter snowstorm occurred in conjunction with heavy winds that resulted in the destruction of thousands of acres of old-growth tree stands. The U.S. Geological Survey, in cooperation with the U.S. Forest Service, collected water-quality data at five sites in the North Fork Elk River...

Using water-quality profiles to characterize seasonal water quality and loading in the upper Animas River basin, southwestern Colorado Using water-quality profiles to characterize seasonal water quality and loading in the upper Animas River basin, southwestern Colorado
One of the important types of information needed to characterize water quality in streams affected by historical mining is the seasonal pattern of toxic trace-metal concentrations and loads. Seasonal patterns in water quality are estimated in this report using a technique called water-quality profiling. Water-quality profiling allows land managers and scientists to assess priority areas...

Characterization of selenium in the lower Gunnison River basin, Colorado, 1988-2000 Characterization of selenium in the lower Gunnison River basin, Colorado, 1988-2000
Selenium concentrations in certain water bodies in the lower Gunnison River Basin, including the lower Gunnison River and lower Uncompahgre River, have exceeded the Colorado water-quality standard of 5 micrograms per liter for selenium. A task force was formed in 1998 that consists of various government agencies, private irrigation companies, and local residents to address the selenium...

Metal loading assessment of a small mountainous sub-basin characterized by acid drainage -- Prospect Gulch, upper Animas River watershed, Colorado Metal loading assessment of a small mountainous sub-basin characterized by acid drainage -- Prospect Gulch, upper Animas River watershed, Colorado
strongly affected by natural acidity from pyrite weathering. Metal content in the water column is a composite of multiple sources affected by hydrologic, geologic, climatic, and anthropogenic conditions. Identifying sources of metals from various drainage areas was determined using a tracer injection approach and synoptic sampling during low flow conditions on September 29, 1999 to...

Evaluation of Metal Toxicity in Streams Affected by Abandoned Mine Lands, Upper Animas River Watershed, Colorado Evaluation of Metal Toxicity in Streams Affected by Abandoned Mine Lands, Upper Animas River Watershed, Colorado
Acid drainage from abandoned mines and from naturally-acidic rocks and soil in the upper Animas River watershed of Colorado generates elevated concentrations of acidity and dissolved metals in stream waters and deposition of metal-contaminated particulates in streambed sediments, resulting in both toxicity and habitat degradation for stream biota. High concentrations of iron (Fe)...
