Abstract:
The objective of this study was to determine physico-chemical characteristics, bacterial contamination of raw and end water samples collected from various selected schools of Garhwal region of Uttarakhand and their impact on human health. It is observed that the uptake of water supply in almost all the schools is primarily suffering from bacteriological contamination of water. Remote Sensing and Geographical Information System (GIS) approach have applied to delineate spatial distribution of water contamination as low and high range. In addition to this, water of few schools is found to be contaminated with iron and fluorine. Tap water samples were assessed for physico-chemical parameters like: pH, total dissolved solids (TDS), total hardness, fluoride (F), nitrate (NO3), total coliform and sulfate (SO4). However, the source of such contamination is still debated. During the study, it is also observed that there is no proper disinfection system practiced in any of these schools. So, there is an urgent need of hour to identify problems related to drinking water and to take corrective measures. A wider approach is needed where water issues are looked at with the aim of reducing massive threat to health of students owing to contaminants present in drinking water higher than prescribed limits. This paper highlights strategies to ensure safe drinking water to the school children for Garhwal region of Uttarakhand.
