A storm sewer is carrying snow melt containing 1200 mg/L of NaCl into a small stream. The stream has a naturally occurring NaCl concentration of 20 mg/L. If the storm sewer flow rate is 2000 L/min and the stream flow is 2.0 m^3/s, what is the concentration of salt in the stream after the discharge point? Assume: completely mixed conditions, NaCl is conservative, and steady state.
