Transcribed Image Text:

A chemical tanker truck crashes into a flooded, abandoned quarry (no soil or sediment on the bottom). It was carrying 1000 kg of benzene which is all released into the quarry and quickly becomes a completely mixed system. The quarry is 10 m deep and has a surface area of 10,000 m². The quarry is fed by a spring with a constant temperature of 20°C and water flows out of it to a local stream at a flow rate of 10 m³/min. (a) How long will the concentration in the quarry violate the applicable NJ Surface Water Quality Standards (FW2) (assume only loss is flow out)? (b) If bacteria is introduced to the quarry that can consume benzene following a 1st order decay process with a decay constant k = 0.01 day-1, how long will the concentration in the quarry violate the regulations?
