Try these first

1. 1.

   What is monitored natural recovery?

   Hint

   What does nature do over time?

2. 2.

   What are refractor chemicals?

   Hint

   What does 'refractor' imply about their nature?

3. 3.

   What does monitored natural recovery rely on?

   • Mechanical intervention
   • Natural ecological processes
   • Chemical treatment

   Hint

   What happens in nature without human interference?

4. 4.

   True or False: Dredging always improves water quality.

   • True
   • False

   Hint

   Think about the turbidity issue.

5. 5.

   Evaluate the environmental effectiveness of both monitored natural recovery and in-situ capping in a hypothetical coastal setting contaminated by oil spills.

   Hint

   Consider timeframes and long-term ecological impacts.

6. 6.

   Design a comprehensive dredging plan that minimizes the resuspension of contaminants while ensuring effective sediment removal.

   Hint

   How can engineering solutions help mitigate environmental impact?
