A hydrogeochemical investigation of metalliferous coal pile runoff and its interaction with soil and groundwater
… can have a dramatic impact on local surface and ground water quality. In order to identify important reactions governing metal transport within subsurface environments subject to infiltration of coal pile runoff, samples of uncontaminated subsoil and aquifer materials adjacent to the D-Area coal …

A study of the effect of the artificial recharge of urban runoff in Roanoke, Virginia
… natural passageways for the escape of surface waters and the ponding of the urban runoff became a problem. In order to solve this, the city drilled several drainage wells. These wells gave the author I an opportunity to study: the effect of the geology on the ground-water, the ground-water …

Characterizing and modeling the hydrologic properties of coal combustion by-products in landfills
… disposed of in unlined landfills can impact the quality of adjacent water resources. In previous studies, CCBs have been found to leach toxic heavy metals such as arsenic, mercury, and lead into groundwater. CCBs include fly ash, bottom ash, and flue gas desulfurization product (FGD gypsum). This …

Managing ground water contamination from agricultural nitrates
Ground water contamination from agricultural nitrates poses potential adverse health effects to a large segment of the rural population of the United States. Contamination is especially prevalent in livestock intensive areas, which produce large quantities of animal waste with substantial nitrogen …

REMOTE SENSING OF WATER QUALITY IN LAKE ERIE USING MODIS IMAGERY DATA
<p>The Great Lakes, as the largest fresh surface water system on earth, greatly affects the quality of life and many aspects of the natural environment from weather and climate to wildlife and habitat. Lake Erie was declared as the first Great Lake that demonstrated a lake-wide eutrophic imbalance …
