Physico-Chemical Parameters of High-Altitude Rivers in the Sagarmatha (Everest) National Park, Nepal

A three-year study (2008–2010) reveals early signs of water quality degradation in high-altitude rivers within Sagarmatha National Park, Nepal. While current levels generally meet drinking water standards (WHO/Nepal), increasing nitrate nitrogen and total phosphorus suggest accelerating anthropogenic impacts—primarily from tourism and waste disposal along major treks. These trends, observed at elevations ranging from 1900 to 5300 meters, highlight an urgent need for proactive monitoring and ecosystem management in this UNESCO World Heritage Site. The research establishes a critical database to track changes and inform conservation strategies.
