Abstract The occurrence of dental/skeletal fluorosis among the population in the study area provided the motivation to investigate occurrence of fluoride in groundwater. The main objective of the present study is to gain insight into spatio-temporal variation of F- contents in groundwater and its relationship with fluorosis prevalence in the study area to answer the following two research questions – (1) What are the controls on spatial distribution of F- concentrations in groundwater (i.e.
