Selenium Mobilization from Shales

Selenium (Se) and salinity (total dissolved solids) are water-quality concerns in much of the arid western US where agricultural and urban irrigation overlie Cretaceous-age shale.  Leaching of Se and salinity from shale can degrade water quality and negatively affect aquatic biota in receiving water bodies. In the upper Colorado River Basin, programs since 1985 have worked to reduce Se and...

Gunnison and Green River Basin Sediment Monitoring and Evaluation Program

Underlying geomorphic processes relevant to the formation and maintenance of backwater habitats are relatively poorly understood, particularly the effects of peak-flow magnitude and duration; sediment deposition and erosion; base-flow magnitude and variability; and antecedent conditions on habitat availability and conditions. Knowledge of sediment dynamics in important river reaches is...

Natural Resources Conservation Service Deep Percolation

The conversion of agricultural land to urban residential land is associated with rapid population growth in the Grand Valley of western Colorado. Information regarding the effects of this land-use conversion on deep percolation, irrigation-water application, and associated salt loading to the Colorado River is needed to support water-resource planning and conservation efforts.

Continuous Water Quality Monitoring on the Pecos River in Southern New Mexico

High levels of salinity in the Pecos River render it less useful for various purposes. It is believed that underground salt deposits in the Malaga area contribute to the increase in the salinity in the Pecos River as it flows through this area.
