Each boat on the river will start with 40 gallons of spring water from Marble Canyon, Arizona. Throughout the trip, your guides will replenish your trip’s drinking water reserves by filtering and disinfecting water from the river. River water is filtered first through a 5 micron sediment filter and then through a .5 micron carbon block. The filtered water is subsequently disinfected with chlorine at a ratio of 1 mg/liter (or 1 part per million) per National Park Service requirements.
Due to space restrictions and environmental concerns, guests may not bring their own supplies of bottled water for the trip. We simply do not have the carrying capacity for each guest to bring sufficient water to stay adequately hydrated nor the space to carry the waste of hundreds of discarded plastic bottles.
