A situation with an industrial input of arsenic directly into the lake at 10kg/Day. The lake volume is 1.2 x 10^8 m^3, and the average depth is 10m. The river velocities are measured as 100 L/min at both the inflow and outflow points. Water samples taken from the rivers show incoming arsenic is 0.02mg/L and the outgoing arsenic is 0.5 mg/L. From the sample, the sedimentation rate in in the lake is estimated to be 200g/m^2 per year.

Calculate the geologic sink and source of As (arsenic) at the lake bottom assuming steady state.
