The town of Pawtucket, RI has two different source waters, a groundwater and a surface water. The two raw drinking waters are mixed as they enter the headworks of the water treatment plant. The two waters are characterized as follows: Flow (MGD) 20 Alkalinity (mg/L CaCO3) pH Water #1 5 6.3 #2 10 275 8.85 What will the alkalinity of Water #2 be after addition of 150 mg/L NAOH? Present your answer in mg/L as CaCO3. Assume a close system.
