2.1. Monitored Natural Recovery

Try these first

1. 1.

   What does Monitored Natural Recovery rely on?

   Hint

   Think about what natural processes might help to clean up pollutants.

2. 2.

   What are refractory chemicals?

   Hint

   Consider what some industrial chemicals aim to achieve.

3. 3.

   What is the primary goal of Monitored Natural Recovery?

   • To implement active remediation immediately.
   • To allow natural processes to reduce contamination.
   • To entirely remove all contaminants.

   Hint

   What approach does MNR encourage for sediment cleanup?

4. 4.

   True or False: MNR can only be used for organic contaminants.

   • True
   • False

   Hint

   Consider the diversity of contaminants that impact sediments.

5. 5.

   Assume you have a polluted area near a river. You’re tasked with proposing an MNR plan. What parameters will you monitor, and why?

   Hint

   Think about what would indicate the recovery of the sediments.

6. 6.

   Critique the effectiveness of using MNR in a heavily industrial zone. What specifics would you adjust considering the risks?

   Hint

   Consider industrial activities that could affect sediment stability.
