On-site granular ferric hydroxide (GFH) systems can be used to remove arsenic from water when daily flow rates are relatively low. If the operating cost is $600,000 per year, what would the initial cost of the GFH system have to be in order to get B/C ratio of 1.0? Public health benefits are estimated $800,000 per year. Assume the equipment life is 10 years and the intrest rate is 6% per year.
