Stocks of water, the liquid derived from precipitation. A constituent of living matter and necessity for all life, it covers a large proportion of the earth's surface.
Modeling effort that integrates a wide variety of geographic, hydrologic, agricultural, climatic, and biological information to help local land managers address resource use issues.
How climate change affects ground water is more complex than surface water because the residence time of ground water can range from days to tens of thousands of years. Discusses some broad climatic processes may affect groundwater resources.
Links to Louisiana statewide aquifer and well information by locating parish on a map or selecting parish, aquifer, region, or type of ground-water data (real-time water levels or geophysical data) from lists.
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.
Shallow groundwater has good quality, but salinity measured in wells suggests the thin lens of freshwater under the coastal plain will be vulnerable to saltwater intrusion as a consequence of pumping.
Lower precipitation and recharge, with deeper groundwater levels, suggest this basin will be less susceptible to contamination than others nearby, but may be susceptible to saltwater intrusion brought on by well pumping.
