Stream water survey along the Annapurna Circuit, Nepal

This paper focuses on stream water testing that took place on the Marshyangdi River, Jharsang Khola and the Kali Gandaki River that are located along the Annapurna Circuit Trek within the Annapurna Conservation Area. Sampling was undertaken from May 16, 2011 to May 28, 2011. A total of 7 samples were taken from the Marshyangdi River, 1 sample from a branch of the Marshyangdi River ( Jharsang Khola), and 5 from the Kali Gandaki River at various accessible points along the trek. An effort was made to sample both upstream and downstream of a village to assess any difference between the two results. Analysis was conducted for Aluminum (Al3+), free Chlorine (Cl), Iron (Fe), Nitrite (NO2 -), and Nitrate (NO3 -), Ammonia (NH3/NH4 +), General Hardness (Ca and Mg) and the presence of Coliform and E. coli.
