A lagoon with volume 1,900 m has been receiving a steady flow of a non-conservative waste (rate constant= 0.29/day) at a rate of 130 m /day for a long enough time to assume that steady-state conditions apply. The waste entering the lagoon has a concentration of 16 mg/L A. What would be the concentration of pollutant in the effluent leaving the lagoon? (2 points) B. If the input waste concentration suddenly increased to 170 mg/L, what would the concentration in the effluent be 3 days later? (3 points)
