Development of Web-Based Application for Generating and Publishing Groundwater Quality Maps Using RS/GIS Technology and P. Mapper in Sattenapalle, Mandal, Guntur District, Andhra Pradesh

Groundwater is an essential source of drinking water for many Indian habitats. Large number of people consumes ground water as it is free from pathogenic bacteria and it is easily available through open well / bore well / tube well. The quality of water plays a prominent role in promoting human health. The paper discusses the usage of P-mapper for publishing the maps on to web portal. Element wise and integrated ground water quality maps are prepared for the elements pH, Total Alkalinity, Total Hardness, Total Dissolved Solids, Chloride and Fluoride. The ground water quality maps are studied with respect to different thematic maps which were prepared by using Remote Sensing and GIS techniques. The main aim and objectives of the current study is in building up of open source web GIS based application which has been developed using open sources like Postgress SQL, Map Guide and Pmapper. This application can be used for bringing the generated ground water quality maps to the authority and or the community and to alert the local community about the steps to be taken about the contaminated water and decision making. In conclusion web based GIS application is a useful tool especially in formulating policy related to water quality using P-mapper as a media.
