Challenge Problems
Push your limits with advanced challenges
You measure the initial DO of your water sample as 8 mg/L and the final DO after 5 days as 2 mg/L. How do you calculate BOD, and what does this result indicate?
💡 Hint: Remember the formula for BOD and interpret the significance of your result.
A sample has a BOD of 100 mg/L. If you dilute it to 10 times its volume for measurement, what is the corrected BOD you should report?
💡 Hint: Factor in the dilution to convert to the original concentration.
