ASSESSMENT OF FLUORIDE CONCENTRATION DUE TO THE DEVELOPMENT OF SUB-SURFACE INFRA STRUCTURE

Abstract

The work aims to compare the spatial distribution of fluoride concentration due to the development of sub surface infrastructure in Chennai metro rail. Ten observation wells are identified in and around Chennai metro rail corridor to access the concentration of fluoride before the opening of tunneling. Data of fluoride concentration are collected for a period of 1995-2014. These observation wells are identified along the sub surface opening to determine the fluoride concentration. The spatial distribution mapping are compared to predict the variations of the water quality fluoride concentration in ground water before and after the construction of the metro rail corridor.
