Try these first

1. 1.

   What does MNR stand for?

   Hint

   Look for an acronym related to natural sediment cleansing.

2. 2.

   Name one advantage of in-situ capping.

   Hint

   Think about the environmental protection aspect.

3. 3.

   What does MNR stand for?

   • Monitored Natural Recovery
   • Mechanical Natural Recovery
   • Managed Natural Remediation

   Hint

4. 4.

   True or False: In-situ capping can damage the local biological community.

   • True
   • False

   Hint

   Focus on the balance of protection and harm.

5. 5.

   You are the environmental manager of a coastal area. Contamination exceeds safe levels. Discuss the assessment criteria you would use to choose between MNR and in-situ capping, detailing your reasoning.

   Hint

   Factor in both immediate and long-term consequences on the ecosystem.

6. 6.

   Design an ideal dredging plan for a region with sensitive marine life. Include how you'd mitigate resuspension and manage the dredged material afterwards.

   Hint

   Think about respecting natural habitats and limiting ecological footprints during dredging.
