Saltwater Intrusion in Groundwater
05/11/25
“How can saltwater corrode freshwater aquifers?”
Aquifers usually hold freshwater. However, coastal aquifers may have saltwater. Usually, saltwater in aquifers is kept at bay because of the natural coastal movement of freshwater. But if groundwater pumping is unsustainable, then the freshwater flow can decrease and suction of saltwater increases, leading to Saltwater intrusion into the aquifer. Saltwater intrusion can destroy drinking water and irrigation sources for people.
