5. Resuspension Mechanisms in Contaminant Transport

Try these first

1. 1.

   What is the main mechanism of contaminant transport?

   Hint

   Consider how substances move in liquid.

2. 2.

   Define resuspension.

   Hint

   Think about what happens to sediment in a river during a storm.

3. 3.

   What is the main transport mechanism discussed for contaminants from sediments to water?

   • Diffusion
   • Evaporation
   • Filtration

   Hint

   Remember how substances disperse in liquids.

4. 4.

   True or False: Resuspension only occurs during calm water conditions.

   • True
   • False

   Hint

   Consider water activity during storms or heavy rains.

5. 5.

   Consider a water body with contaminated sediments. How would you model the potential impact of heavy rainfall on contaminant levels in the water?

   Hint

   Think about the factors influencing both diffusion and sediment stability.

6. 6.

   Discuss the role of colloidal particles in contaminant transport. How do they affect water quality in sediments?

   Hint

   Consider the characteristics of colloids and their behavior in water.
