5.1. Examples of Remediation

Try these first

1. 1.

   What is bioturbation?

   Hint

   Think about how organisms interact with sediment.

2. 2.

   Define advection.

   Hint

   Related to how water or air carries materials.

3. 3.

   What process involves organisms disturbing the sediment to enhance transport?

   • Advection
   • Bioturbation
   • Diffusion

   Hint

   Think about organisms interacting with soil.

4. 4.

   True or False: Advection causes substances to move from low to high concentration.

   • True
   • False

   Hint

   Consider what drives the movement of air or water.

5. 5.

   Consider a hypothetical contaminated site. How would you design a study to measure contaminant flux using the enclosed volume method? Detail your steps.

   Hint

   Think about both the physical setup and the sampling process.

6. 6.

   Using a case study approach, analyze the social implications of community involvement in sediment remediation efforts. What key factors might influence success?

   Hint

   Reflect on the dynamics between the community, scientists, and policymakers.
