As an environmental engineer, you want to measure the BOD5 of a real wastewater sample. You dilute 30 ml of your sample with pure water to make a standard 300 mL BOD solution with an initial DO of 10.0 mg/L. To ensure an accurate test, it is recommended to have at least a 2.0 mg/L drop of DO during the five-day test, and the final DO should be at least 2.0 mg/L. In what range of BOD5 of original wastewater sample, you will get convincing results by using this testing process?
