12) A waste stream mixes with a river. After mixing the river contains 9.65 mg/L dissolved oxygen, and 13.61 mg/L BOD. At the temperature of the river after mixing, the saturation DO is 12.3 mg/L and the BOD decay rate constant and reaeration coefficient are 0.21 and 0.18 d?, respectively. 12A) The initial oxygen deficit is best approximated to be: 01.31 mg/ U 0mg/ 2.65 mg/ 0] 9.65 mg/ 12B) What value best represents the time of travel downstream of the mixing location to where the dissolved oxygen in the river will be the lowest? 1.31 days U] 2.62 km 4.22 days 05.14 days
