Groundwater, which plays an important role in meeting the requirements of<br />
humans is an integral part of the environment, and hence cannot be looked upon in<br />
isolation. There has been a lack of adequate attention to water conservation, efficiency<br />
in water use, water re-use, groundwater recharge, and ecosystem sustainability. An<br />
uncontrolled use of the bore well technology has led to the extraction of groundwater at<br />
such a high rate that often recharge is not sufficient. The study area selected was<br />
Palakkad district of Kerala with the main objective of evaluating the groundwater<br />
quality in a semi urban setup and suitability for various uses. As GIS is an integrating<br />
tool for accurate representation and analysis of groundwater quality data, it was used to<br />
bring out effectively the ground water quality index of the study area. The source of<br />
attribute data is field data and laboratory analysis data. The physical and chemical<br />
parameters were tested in the laboratory to study the concentration of constituents<br />
varying in different locations. The land use pattern, roads, streams etc were used for the<br />
GIS analysis. Three water quality index maps were brought out by analyzing monthly<br />
water quality data of three different years and based on which water quality modeling<br />
was done in community level. The result of the study was used for the preparation of<br />
water quality management strategies at local level.<br />
