Appraisal of Groundwater Quality around two International Tourism Destinations, Kovalam and Vizhinjam, Thiruvananthapuram, Kerala, India

The current groundwater state of Kovalam and Vizhinjam area was swot up in detail. The importance of these two places fetches much emphasis for the present study. Vizhinjam is the place where an international port is intended to come up and the pilot activities have already been set off. The Kovalam is the second spot which is an international tourism destination where owing to the invasion of hefty scale buoyant population, both the quality and quantity of groundwater, is being pretentious. While analysing the water quality, problems identified include the acidic water content, incident due to the low pH in the open wells and the microbiological contamination at multiple locations posturing peril to the locale. Imperative parameters, which have commanding influence were projected into a geospatial platform and primed various thematic maps. By integrating the thematic maps by assigning weighted parameter rating (WPR), a groundwater quality zonation map was also prepared. This map is ready to lend a hand to locate zones where good quality water is accessible. Apart from the anthropogenic blemish, the doable sources of geogenic contamination were also considered.
