... However, water resources management has become increasingly complex over time. Large-scaTe groundwater development throughout the nation has resulted in many ill effects, including lowering of water tables, salt-water intrusion, subsidence, and Towered baseflow in streams, with corresponding ecological damage.

... Aquifer management: Optimizing groundwater extraction while limiting undesirable effects such as salt-water intrusion, land subsidence and harm to ecosystems, Aquifer Storage and Recovery (ASR) projects: Use of aquifers for repeated storage and recovery of water of varying quality, · Groundwater recharge: Quantifying rates, spatial locations, and mechanisms of recharge from local to regional scale, · Surficial aquifers: Evaluating hydrogeology, water-level changes, and water quality changes, .

... The current Middle Rio Grande Basin and Southwest Groundwater projects have used this management approach with some success. Coordination should include the identification of common data collection, QA/QC, sampling, and archiving protocols to maximize each issuedriven study's contribution to the regional and national groundwater information base.

... Although the Survey obviously cannot and should not influence the specific research activities of such organizations, it can provide expert guidance and advice on specific scientific issues and can help shape the national scientific agenda with respect to groundwater research. In addition to these forms of outreach, however, the GWRP should, along with the other groundwater programs within the USGS, emulate the National Streamgauging Program in moving aggressively to post primary and interpretive data on the Internet.

... It can be viewed at a national, state, or local scale, is organized thematically, and can handle many different data types. Well locations can be plotted and linked to water-level data in a way analogous to the existing system for streamflow data.
