A river with a flowrate (Q) of 850 cfs (cubic feet per second) has a total dissolved solids (TDS, think table salt in water) concentration of 55 mg/L. At some point, an industry discharges a water stream with a TDS concentration of 2,500 mg/L into the river. If the maximum TDS concentration allowed in the river is 250 mg/L and there are no other TDS inputs, answer the following: a. What is the maximum allowable wastewater flow from the industry (in cfs)? b. If the 250 mg/L TDS level is met downstream, what percent of the TDS comes from the industry?
