2.2. In-Situ Capping

Try these first

1. 1.

   What is in-situ capping?

   Hint

   Think about how we can cover something to keep it from spreading.

2. 2.

   What does MNR stand for?

   Hint

   One approach to monitor sediment without disturbing it.

3. 3.

   What technique involves placing a clean layer over contaminated sediments?

   • Dredging
   • Monitored Natural Recovery
   • In-Situ Capping

   Hint

   What method specifically protects underlying sediments?

4. 4.

   True or False: In-situ capping can adversely affect local organisms.

   • True
   • False

   Hint

   Consider who lives in the sediment layers.

5. 5.

   A city plans to cap a section of contaminated sediment in a busy harbor. Discuss the factors they should consider in the cap's design, including materials and potential ecological impacts.

   Hint

   What materials could act as 'filters' for sediments?

6. 6.

   A study shows that after applying in-situ capping, contaminant levels decreased over time. Discuss how long-term monitoring plays a role in measuring the effectiveness of this strategy.

   Hint

   What data would you need to observe for effectiveness?
