What are the primary consequences of salt water intrusion into freshwater aquifers? Mark all that apply.

• Reduction in freshwater storage capacity in aquifers due to displacement by denser salt water

• Abandonment of wells due to increased salinity making the water unfit for consumption or irrigation

• Extreme subsidence of the land due to empty pore spaces
