Water Quality Index (WQI), a technique of rating water quality, is a effective tool to assess overall quality of water and ensure sustainable safe use of water for various purposes. The present work is aimed to assess the pond water quality of Anad panchayath in Nedumangadu block for knowing the suitability of various purpose by calculating the WQI and using Geographical Information System (GIS) techniques. Thirteen pond water samples were collected from the ponds of Anad panchayath for comprehensive physico-chemical analysis. Nine parameters were considered for calculating the WQI such as: pH, chloride, calcium, magnesium, total hardness and total dissolved solid, potassium, dissolved oxygen. The spatial distribution maps of the 13 parameters were prepared by using GIS software. The computed WQI value ranges from 10 to 23. The pond water of the study area fall in Good category indicating the pond water in the area is suitable for domestic and agricultural purposes.
