In October, LIFESAVER sponsored a group of individuals with LIFESAVER bottles as they embarked on their trip to Everest Base Camp which is at an altitude of 17,575 ft.
The water unless bottled was contaminated. The photos below show an ice pool which is Khumbu Glacier. This glacier like most is contaminated water and needs to be filtered before drinking. Given the lack of toilets in the area, filtering is doubling important. The other photos of the man in the black jacket were taken at a place called Gorek Shep which is 2 hours walking distance from base camp. This water is also contaminated.
Studies concerning the quality of water at base camp have found that not only is it contaminated with human waste but high levels of silicon and toxic metals, plus the odd human body or two.
During the trip, the group stayed in guest houses where the water is piped in from local streams and rivers that flow off the glaciers. There are signs to say don't drink this water. So most people rely on bottled water.
The group used their LIFESAVER bottles everyday to ensure a safe water supply for that days' trek.
