GIS Based Inverse Distance Weighting Spatial Interpolation Technique for Fluoride Occurrence in Ground Water

摘要

This study was conducted to evaluate fluoride contamination in ground water of the central part of Nagaur district where ground water is the main source of drinking as well as irrigation. Samples from hand pumps and tube wells of forty four stations were analyzed during the summer session with the help of standard methods of APHA. The analytical results show that eleven ground water samples are unfit for drinking purpose. A map has been prepared using an inverse distance weighting method which shows the fluoride concentration in the study area. The maximum concentration was recorded in the Sirsi village while the minimum was found in Sabalpura.
