A small town withdraws water from the local river and disinfects it before delivering it to its residents. Most residents own reverse osmosis water purification units, which are used for producing drinking water. The town treats 10,000 L of water per month, of which the residents use 5 percent for drinking after reverse osmosis. The effluent from the town has an average biological oxygen demand (BOD) of 10 mg/L. The acceptable BOD is 1 mg/L, and the natural BOD is 0.1 mg/L. 

1. Calculate the direct green, blue, and gray water flows in this town. 

2. The town produces electricity by means of a coal integrated gasification combustion cycle process. Estimate the water and carbon footprints of this electricity. You may assume that both disinfection and reverse osmosis use this electricity.
