Challenge Problems

Push your limits with challenges.

Question 1

Design a hypothetical scenario where a BOD test initially indicates zero, but further investigation reveals high levels of organic matter. What steps would you take to ensure accurate analysis?

💡 Hint: Reflect on how microorganism absence affects BOD readings.

Question 2

You are tasked with comparing BOD results from two different laboratories. Lab A reports a BOD of 15 mg/L at 20°C after 5 days, while Lab B reports 10 mg/L at the same conditions. Consider the factors that might cause discrepancies between their readings.

💡 Hint: Check if they followed the same standard methodologies!
