Challenge Problems
Push your limits with advanced challenges
Calculate the impact of a DNAPL spill in a hypothetical river where the flux from sediment is observed to be 0.1 mg/L/day. If the goal is to keep the concentration in the water below 0.05 mg/L, what measures could be taken to mitigate this?
💡 Hint: Consider both physical dilution methods and chemical treatment options.
Discuss a scenario where a river with frequent DNAPL spills shows a significant reduction in biodiversity. Evaluate the ecological impacts of such contamination.
💡 Hint: Think about which organisms are most affected by contaminants.
