Data sets on spatial analysis of hydro geochemistry of Gudur area, SPSR Nellore district by using inverse distance weighted method in Arc GIS 10.1.

The data represent on specific water quality monitoring parameters for 40 sampling points at Gudur area and Hydro geochemistry showed as spatial variation diagrams such as pH, TH, EC, TDS, SO, HCO, Ca, Mg, Na and F of Gudur area. The spatial maps show that high concentrations of physicochemical parameters in the North-East (NE) and South-East (SE) directions have been observed. The proper planning and various management activities were carried out with the help of these maps. The Gibbs diagram indicates the rock water interaction and bivariate plots data indicates the silicate weathering processes.
