Challenge Problems
Push your limits with advanced challenges
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!
