33.9. Saltwater Intrusion in Coastal Aquifers

Try these first

1. 1.

   What is saltwater intrusion?

   Hint

   Think about how seawater and freshwater interact.

2. 2.

   Name one technique to prevent saltwater intrusion.

   Hint

   Consider how managing water extraction could help.

3. 3.

   What causes saltwater intrusion in coastal aquifers?

   • Excessive rain
   • Excessive pumping
   • Low evaporation

   Hint

   Consider what happens when too much water is taken from the ground.

4. 4.

   True or False: Artificial recharge can help prevent saltwater intrusion.

   • True
   • False

   Hint

   Think about the benefits of adding water to an aquifer.

5. 5.

   Imagine you are a water resource manager in a coastal city facing saltwater intrusion. Outline a policy proposal involving community engagement and education on the importance of local aquifer management.

   Hint

   Focus on how to involve the community and raise awareness about aquifer health.

6. 6.

   A coastal city has a historical average water extraction of 100,000 gallons per day but has increased this to 150,000 gallons per day. Analyze the potential consequences this may have on saltwater intrusion and propose mitigating actions.

   Hint

   Consider the relationship between water pumping rates and aquifer health.
