Lake Operon has a surface area of 5.5 X 10⁸ m2 . There is a stream that flows in to the lake with a phosphorus concentration of 25 µg/L and a flow rate of 75 m3 /s. The phosphorus settling rate (vs) within the lake is 8 m/yr. Assume the incoming stream has the same flow rate as an outgoing stream and that settling occurs over the entire lake. Calculate the maximum point source (S) concentration (g/s, three significant figures) that can be allowed so that the concentration of phosphorus in the lake is 0.01 g/m3 . You can ignore the volumetric flow from the point source.
