Water canals are superb habitats for the study of ecosystem dynamics: interactions among biological, chemical and physical processes are frequently either quantitatively or qualitatively distinct from those on land or in air. Humans frequently depend on canal for a great many ‘goods and services’ such as drinking water, waste removal, fisheries, agricultural irrigation, industrial activity and recreation. The present study was carried out for evaluation physico-chemical parameters of surface water quality in Lachhiwala canal of Dehradun district. The calculated value of Water Quality Index (WQI) as 111.259 according to Standard Rating of Water Quality water source of Lachhiwala canal was found 'E' grade and its water quality is explained as Unsuitable for drinking purpose. This research offered the need of an effective evaluation of the Surface water quality and its utility for human health. Reference 1. S. T. Kalavathy, R. Sharma, and P. Sureshkumar, Arch. Environ.
