Bodies of rock that contain sufficient saturated permeable material to conduct ground water and to yield significant quantities of water to wells and springs. [Glossary of Geology, 4th ed.]
This program encompasses regional studies of ground water systems, multidisciplinary studies of critical ground water issues, access to ground-water data, and research and methods development.
Using ground-water geochemical analyses, and mathematical models, the factors affecting the quality of public water supply were identified as pumping schedule, screened interval, past land use within the recharge area, and natural geochemical conditions.
Using ground-water geochemical analyses and mathematical models, the factors affecting the quality of public water supply were identified as mixing of very recent recharge with older water, karst features, natural geochemical processes, and pumping.
Well vulnerability results from the young age of groundwater. Karst features permit contaminants to move into the aquifer easily, leading to a well mixed aquifer; geochemical processes do not degrade contaminants quickly.
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.
Discussion and links to research for the multi-disciplinary investigation on the Norman Landfill located on alluvium associated with the Canadian River in central Oklahoma.
Summarizes graphically the areas where water levels have dropped, and by how much, in this extensive underground water reservoir that covers several states in the mid-continent.
