Question 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?
Show hintHide hint
Think about how the different factors interact with each other over time.
Question 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?
Show hintHide hint
Reflect on interactions that may arise with implemented remediation methods.
