2.7. Equilibrium between Sediment and Pore Water

Try these first

1. 1.

   What does D-NAPL stand for?

   Hint

   Think about the density compared to water.

2. 2.

   What happens to L-NAPL when it spills on water?

   Hint

   Consider the density of the substance.

3. 3.

   What is the primary characteristic of D-NAPLs?

   • Less dense than water
   • Denser than water
   • Same density as water

   Hint

   Think about how density affects behavior in liquids.

4. 4.

   True or False: L-NAPL will remain submerged under water.

   • True
   • False

   Hint

   Consider the definitions of L-NAPL and its properties.

5. 5.

   Given a contaminated sediment site with known concentrations of D-NAPL, how would you model the potential spread into the surrounding water over the next decade?

   Hint

   Think about how the different factors interact with each other over time.

6. 6.

   Analyze a scenario where a new remediation method is applied to a site with long-standing L-NAPL contamination. What factors would need to be modeled to assess efficacy?

   Hint

   Reflect on interactions that may arise with implemented remediation methods.
