Saltwater intrusion is the movement of saline water into freshwater aquifers, which can lead to groundwater quality degradation, including drinking water sources, and other consequences. Saltwater intrusion can naturally occur in coastal aquifers, owing to the hydraulic connection between groundwater and seawater .
Evaporation of groundwater increases the chemical concentration of water. Or intrusion of seawater increases the chemical concentration of water. Water is too saline to be drinkable. [47] Saline 10000-36000 Similar to seawater. Strong evaporation of groundwater or fully mixing with seawater. Hyper-Saline 36000-100000
Common approach for monitoring seawater intrusion include measuring groundwater level, hydrograph analysis, water quality sampling and geophysical logging. These procedures provide discrete and tangible information for early-warning signs regarding saltwater intrusion adjacent to lands and groundwater aquifers.
