The USGS Surface-water quality and flow Modeling Interest Group (SMIG) is interested in surface-water quality and flow modeling activities with links to articles, model archives, data archives, clearinghouse, mailing list, classes, and meetings.
Site describes studies using flow visualization and rock matrix pressure measurements to study flow through fractures in the unsaturated zone, which plays an important role in water infiltration and contaminant transport.
National Water Information System (NWIS) real-time data on selected ground water sites, ground water level data, site inventory of wells, test holes, drains, springs and excavations and ground water-quality data for the United States.
Sampling program to determine if pesticides are present in ground water, in accordance with Wyoming's Generic State Management Plan for Pesticides in Ground Water (SMP).
Overview of research to measure, predict, and understand the flow of water through soil and rock between the land surface and the water table with links to field sites, laboratory methods, theoretical developments, publications, and personnel.
Description of the project to publish new bedrock geologic maps in the United States to advance the understanding of the region's bedrock aquifers. Includes list of projects.
Project summary, photos of logging truck, and bibliographies on log interpretation techniques and instrumentation to record geophysical data in wells and test holes for studying ground water hydraulics and evaluate waste disposal sites.
Overview of fractured rock research aimed at understanding the movement of water through fracture networks, and characterize field conditions influencing contaminant migration. Includes programs and publications.
