Abstract

Water is one of the main natural’s resources in the world and it’s very essential for all human livings not only for human, animals, and agricultural purpose and other activities. Kanchipuram district lies adjacent to Chennai in the state of Tamil Nadu in India. It is bounded in the west by Vellore District and Thiruvannamalai District, in the north by Thiruvallur District and Chennai District, in the south by Viluppuram District and in the east by the Bay of Bengal. Study area was generated all along the coast with a width 15 km. A total of 171 villages were within the total area of 1678 sq.km. A detailed investigation on ground water quality status for ground water sample (71 locations) along Kanchipuram Coast was taken up for pre monsoon data for the years 2011 – 2015 in ArcGIS software. Ground water variables such as pH, EC, TDS, Total Hardness, NO3, SO4, Cl, F, CO3, HCO3, Na, Ca and Mg were analyzed for statistics in MS Excel for pre monsoon season. Graphs were plotted for each parameter across all years separately for pre monsoon to understand parameter variability between seasons and years. Spatially interpolation tool followed by kriging techniques exhibited spatial spared values based on environmental conditions of pre monsoon were analyzed graphically. Results of the analysis enumerated that pre monsoon value for the all the 13 variables. Critical variable such as chloride, fluoride, nitrate, sulphate, responses was higher for pre monsoon season. Spatial map of these variables responded for higher concentration of the northern coast of the study area and lower concentration on the middle and southern part study area. Key words - pH, EC, TDS, Total Hardness, Remote sensing and GIS
