Try these first

1. 1.

   What is monitored natural recovery?

   Hint

   Think about nature’s way of cleaning up.

2. 2.

   What is in-situ capping?

   Hint

   True or False: Refractory chemicals are designed to degrade easily.

   • True
   • False

   Hint

   Recall what makes them difficult to manage.

5. 5.

6. 6.

   Evaluate the pros and cons of using capping versus dredging in a polluted harbor.

   Hint

   Consider both immediate and long-term effects.
