GIS Based Water Quality Analysis at Hand Pump Locations for Allahabad City

It is common knowledge that fresh water, a finite and fragile resource is increasingly becoming scarce day-by-day. According to a report of Global Environment Outlook, the global fresh water consumption has raised six fold between 1900 and 1995 even more than twice the rate of population growth. To provide safe drinking water, it is required to plan and design a project with economy and safety. Planning is all about dealing with various kinds of data, to analyze them and to make a suitable decision. The present study has been carried for Allahabad city. In the present work, an integrated geographic database has been created using GIS consisting of water quality parameters of Allahabad city. The GIS based evaluation has given the spatial, graphical and statistical representation. Based upon the analysis carried out, it may be concluded that almost all the hand pumps require treatment of water for bacteriological contamination to make it safe for drinking or else the consumption of this water may be stopped to reduce the outbreak of health hazards.
