Groundwater comprises about 30 percent of Earth’s available freshwater; however, this vital resource is often contaminated by industrial or agricultural sources. The efficiency of existing groundwater ...

Groundwater contamination in heterogeneous aquifer systems containing high-permeability zones (analogous to fractures) and adjacent low-permeability zones (analogous to rock matrices) persists long ...

Hydraulic conductivity is a major parameter affecting the output accuracy of groundwater flow and transport models. The most commonly used semi-empirical formula for estimating conductivity is ...

Groundwater is declining across Eastern Washington's complex, interconnected aquifer system, as people draw on it for irrigation, drinking and other uses at a pace that threatens its sustainability, ...
