Blue Lake is 3500 m long and 2800 m wide. The average depth is 20 m. The lake is fed by a stream having an average flow rate of 6.9 m^3/s. The stream flows through agricultural land, and the average concentration of the herbicide Kill-all in the stream is 33.1 μg/L. Kill-all degrades biologically with a rate constant of 0.18/ day.
Assuming that the lake is at steady-state conditions and completely mixed, what would be the Kill-all concentration in the lake under these conditions?
