From Puget Sound to Everest: water quality studies may aid climbers

Share

By Jeff Rice Scientists at the Puget Sound Institute (PSI) and the Center for Urban Waters have taken their research to the highest place on earth. The same techniques used to analyze water quality in Puget Sound are being applied at Everest base camp. Water samples were collected on the mountain and sent back to PSI researchers Andy James and Justin Miller-Schulze as part of a study on potential human impacts on drinking water. New techniques can identify chemical tracers known as CECs that indicate human sources.
