A plant discharges 4000 gal/min of treated wastewater that contains 0.25 mg/L of PCBs (polychloronated biphenyls) into a river that contains no measurable PCBs upstream of the discharge. If the river flow rate is 1500 ft3/s, after the discharged water has thoroughly mixed with the river water, what is the concentration of PCBs in the river in milligrams per liter?
