How does saltwater intrusion impact the water supply 2 answers

Question

Causes over pumping of water
Decreases the amount of useable water
Causes saltwater to mix with freshwater
Recharges aquifers
Improves the water in aquifers near the coast

Answer 1

Saltwater intrusion primarily impacts the water supply in the following ways:

1. Decreases the amount of usable water: As saltwater encroaches into freshwater aquifers, it diminishes the proportion of freshwater available for human use, agriculture, and drinking water. This decline in usable water can lead to shortages and challenge effective water management in coastal regions.

2. Causes saltwater to mix with freshwater: The intrusion results in a mixing of saline (salt) water with freshwater resources. This contamination alters the quality of water, making it unsuitable for consumption and agricultural irrigation without treatment, thereby posing significant challenges for water supply sustainability.

These impacts can have profound consequences for communities reliant on coastal freshwater sources.
