Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given a water sample has an initial DO of 8 mg/L and a final DO after incubation of 2 mg/L, calculate the BOD. How would you interpret this value in terms of water quality?

💡 Hint: Remember the formula for calculating BOD.

Challenge 2 Hard

Consider a situation where you analyze two samples: one with biodegradable waste and one with non-biodegradable waste. Both samples show similar BOD levels. What conclusion can you draw from this?

💡 Hint: Think about the implications of what non-biodegradable materials do in the testing process.
