Spatial Water Quality Analysis Of Vadodara district Using Geo Informatics Tools Suman Agrawal , Dr. H.M.Patel ,Indra Prakash3, Ajay Patel4 Abstract: The Vadodara District, covering an area of 7788 km2 is occupied by varied type of geological formations ranging from Archaean to recent. Ground water samples from 65 locations of the watershed bounded by north latitude 21°49’19” and 22°48’37”and east longitude 72°51’05”and 74°16’55 were collected. The collected samples are distributed over three main hydrogeological provinces, Aravalli terrains, Deccan trap & associated Cretaceous sediments terrains and Alluvium areas. With the progressive development of Vadodara city and its neighboring area, there…show more content…
These reflect in deviation in groundwater quality in space & time over wider ranging geological provinces and in areas of wide-ranging hydrologic regimes. Spatial analyst tool is used to evaluate the map which represents the variation of water quality using the help of ArcGIS. Study Area: The present study is related to Vadodara district, Gujarat, India. It lies between north latitude 21°49’19” and 22°48’37”and east longitude 72°51’05”and 74°16’55”. The Vadodara District, covering an area of 7788 km2 is occupied by varied type of geological formations ranging from Archaean to recent. . The district is divided into 12 talukas and 20 towns and 1545 inhabitant villages. The area is bounded by River Mahi in the north and Dhadhar in the south. The major sources in the study area are Ajwa, river Mahi and tube wells. The topography of the area is generally flat. The location map of Vadodara district is as shown in fig 1. Fig.1. Location map Geology: Geologically, the formations underlying district area range in age from Pre-Cambrian to Recent. The Pre-Cambrian formation, termed as Aravalli formation occurs in forms of quartzite Phylite, schist, gneiss etc., rocks are basically metasedimet. Granite of contemporary age occurs as intrusive and
