Problem

silver lake is feed by a clean stream and discharges into the lilla river. new development in the area has led to a plant discharging tetrachlorobiphenyl, a pcb, into the lake. assuming the lake has a constant volume of 8 million m3, what is the steady-state concentration of tetrachlorobiphenyl in the lake assuming the plant discharges its waste at a rate 10 m3/s and the waste stream contains 75 mg/l of tetrachlorobiphenyl? present a complete mass balance solution.
