A geographic information systems technique for monitoring contaminants in Galveston Bay, Texas A geographic information systems technique for monitoring contaminants in Galveston Bay, Texas
A geographic information system (GIS) was used to compile a series of databases containing details concerning metal contamination and pollution sources to study their impacts on the Galveston Bay (TX) ecosystem. Using these databases, a series of maps with various overlays was created with ARC/INFO software. These maps allowed patterns of spatial distribution of numerous variables to be...

Acid base accounting--An improved method of interpreting overburden chemistry to predict the quality of coal-mine drainage Acid base accounting--An improved method of interpreting overburden chemistry to predict the quality of coal-mine drainage
Acidic mine drainage (AMD), which results from the accelerated oxidation of pyrite (FeS2 ) in mined coal and overburden, has contaminated thousands of miles of streams in the Appalachian region of the United States. Acid‐base accounting (ABA), which simplifies the complex hydrogeochemical system through use of a limited number of variables, commonly is used to predict the post‐mining...
