The Survey currently has several projects that investigate the use of artificial recharge to manage ground-water resources and the use of

brackish or saline aquifers for storage and recovery of fresh water. During the 1960s-1980s, the USGS conducted many similar studies

investigating aquifer storage of imported water or treated sewage effluent supplied by major engineering projects in several states.  These

studies indicated that artificial recharge of fresh-water aquifers can be successful when sediment is removed and microbial treatment is

practiced; but that storage of fresh water in saline aquifers may result in aquifer clogging due to clay-water interactions, and density-driven

migration of injected fresh water may reduce fresh-water recovery. Past lessons learned should be considered in any new projects.
