How does saltwater intrusion impact the water supply? what are the two correct answers.
1. It improves the water in aquifers near the coast.
2. It decreases the amount of usable drinking water.
3. It causes saltwater to mix with freshwater.
4. It causes over-pumping of water.
5. It recharges aquifers.
2. It decreases the amount of usable drinking water.
3. It causes saltwater to mix with freshwater.
The correct answers are:
2. It decreases the amount of usable drinking water.
3. It causes saltwater to mix with freshwater.
Saltwater intrusion impacts the water supply by decreasing the amount of usable drinking water. When saltwater infiltrates freshwater aquifers, it contaminates the freshwater, making it unsuitable for consumption.
Additionally, saltwater intrusion causes saltwater to mix with freshwater, leading to a degradation of water quality. This can have detrimental effects on ecosystems, agriculture, and other water-dependent industries.
