General Biology I
Saltwater intrusion is the movement of saline water into freshwater aquifers, which can occur when groundwater is over-extracted or during periods of sea-level rise. This process can significantly alter the chemical composition of the water supply, impacting ecosystems and human water resources. Understanding saltwater intrusion is crucial for managing water resources and maintaining the balance of biogeochemical cycles, especially in coastal regions where freshwater and saltwater interfaces are present.
