Dust control for 3 months: Using a cost of $10/1,000 gallons of water <br />equals $300 per day for 30,000 gallons of water. For 78 days (6 days per <br />week for 3 months or 13 weeks) of dust control, the water supply would <br />cost $23,400. Using a cost of $220 for a round trip to bring 10,000 gallons <br />of water to the site equals $660 per day to haul water to the site.
