摘要

The quality of water is a vital concern for mankind since it is directly linked to human health. The present work is carried out with an objective to assess and map the spatial variability in the groundwater quality parameters in Mandvi Taluka, Surat district Gujarat, India. A total fifty-seven representative ground-water samples from different bore wells and hand pumps from Mandvi Taluka has been collected and analyzed for major cation and anions with fluoride concentration for the pre-monsoon and post-monsoon seasons. Ground water in the region is found alkaline, with presence of bicarbonates in nature and very hard. Weathering and leaching of F- bearing minerals under the alkaline conditions favors the high F-?concentration. Presence of low total hardness, low calcium hardness, high chlorides, high bicarbonates and some anthropogenic factors such as intensive and long-term irrigation, heavy use of fertilizers are the supplementary factors to further enhance the F- concentrations in the groundwater. Moreover, GIS spatial distribution maps give better visual image to understand the spatial distribution pattern to overlook better conclusion.
