Abstract


Quality of groundwater is an important factor, for sustainable agricultural, industrial and domestic usages. Ramanathapuram is one of the coastal rural taluk which has high tourism activities and more issues on sea water intrusion in the past three decades. Since it has high rate of urbanization leads poor water quality in the urban areas. The study involves assessing the status of ground water quality the study has been designed to assess the ground water status and to prepare the spatial distribution map for water quality parameters such as pH, EC, TDS, calcium, magnesium, total hardness and chloride at Arc GIS environment. The data were used in the attribute table for preparing spatial distribution maps through IDW (Inverse Distance Weighting) interpolation techniques. It is observed that keelakarai town panchayat area has severely affected area in respective with ground water quality. Spatial distribution maps of each parameter were discussed in the full length paper. Also study has suggested suitable management planning strategies to improve the quality of ground water.

*2016 Journal Impact Factor was established by dividing the number of articles published in 2014 and 2015 with the number of times they are cited in 2016 based on Google Scholar, Google Search and the Microsoft Academic Search. If ‘A’ is the total number of articles published in 2014 and 2015, and ‘B’ is the number of times these articles were cited in indexed publications during 2016 then, journal impact factor = A/B.
