Abstract

Groundwater is the major source of drinking water in urban and rural India.
Groundwater is primarily used for various purposes like drinking, washing, irrigation, etc.
Groundwater can become contaminated in many ways. The study has been carried out to assess
the fluoride in groundwater of Coimbatore district. The secondary data of groundwater has
been collected from PWD, Chennai, Tamil Nadu for the years of 2014 to 2018. Geographic
information system (GIS) approach is used to develop spatial information and knowledge about
fluoride in groundwater quality. Fluoride plays an important role in human metabolism within
the permissible limit. But it is exceeded by many activities mainly by the human activities.
High level of fluoride cause major impact on human health. It can replace calcium ion in bones
and teeth, which can lead to fluorosis. Therefore this study was aimed to identify the high and
low risk of fluoride contamination in groundwater. The study revealed that high level of
fluoride 2014 (2.83mg/l), 2015 (1.86mg/l), 2016 (3.6mg/l), 2017 (1.56mg/l), and 2018
(1.68mg/l). It provides an understanding into the problem of fluorosis among people in the
study area, where fluorosis is a public health problem of significant impact. Ambrampalayam,
Puliampatti, Puravaipalayam, Ettimadai, Sirumugai and Therampalayam where the places
shows the high level fluoride and people experiences the symptoms of dental fluorosis. There is
compulsory need for defluoridation of the groundwater before consumption
