2. Options for Remediation

Try these first

1. 1.

   What does monitored natural recovery rely on?

   Hint

   Think about the role of nature in cleaning up pollutants.

2. 2.

   Name one type of dredging method.

   Hint

   Choose one of the two common methods.

3. 3.

   What is monitored natural recovery?

   • Passive remediation relying on natural processes
   • Active removal of sediments
   • Immediate chemical treatment

   Hint

   Think about the relationship between intervention and nature.

4. 4.

   True or False: In-situ capping can harm the biological life beneath it.

   • True
   • False

   Hint

   Consider how a barrier might interact with life forms below.

5. 5.

   Evaluate the effectiveness of using only monitored natural recovery in a heavily polluted coastal area with known refractory chemicals.

   Hint

   Weigh the properties of the chemicals against natural processes.

6. 6.

   Design a remediation plan for a coastal site proposing to use a combination of in-situ capping and monitored natural recovery. Discuss potential implications.

   Hint

   Think about how both methods interact and the monitoring responsibilities.
