The U.S. Geological Survey Water Resources in Kansas presents its research on two major topics: "the fate, transport, and degradation of organic contaminants in the environment with special [focus] on nonpoint-source contamination from agricultural chemicals" and "the environmental issues of emerging contaminants and how they affect the water." After discovering the group's objectives and procedures, users can learn about the projects in Geochemical Process Studies ant Water Quality Surveys. Users can find introductions to solid-phase extraction, gas chromatography, mass spectrometry, and other methods of analyses. Researchers can find links to abstracts and publications.
