A sample has a BOD5 measured as 8.4 mg/L. If the dilution factor was 5, calculate the true BOD of the sample, considering the potential dilution water's BOD is negligible.
Show hintHide hint
Multiply the measured BOD by the dilution factor to find the true BOD.
Question 6.
Consider a scenario where a municipality is assessing the health of a river. What BOD levels would imply significant pollution, and what actions would you suggest to them?
Show hintHide hint
Think about standard BOD thresholds for water quality.
