Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

A water sample has an initial DO of 12 mg/L and after dilution shows a final DO of 3 mg/L. If the dilution factor used was 10, calculate the BOD and account for the fact that your dilution water had a BOD of 1 mg/L.

💡 Hint: Don't forget to subtract the BOD of the dilution water!

Challenge 2 Hard

Discuss the potential implications of using a dilution water source with unknown organic pollution levels. What steps could you take to verify its purity?

💡 Hint: Why is the source of your dilution water so critical?
