An investigation on the pollution status of holy aquifers of Rameswaram, Tamil Nadu, India.
The Study area is the sacred Ramanathasamy temple and selected for the characterization of physico-chemical parameters viz., pH, EC, TDS, Salinity, TA, TH, Ca( + 2), Mg( + 2), Chloride and Fluoride for 22 groundwater samples and the impact of pre- and post-monsoon on the groundwater quality was also studied. The study area is well known for the chronic fresh water shortage and the locals depend mostly on springs for their fresh water needs. The Water Quality Index (WQI) computed shows the transfer of samples under unacceptable quality to acceptable quality. The Langelier Saturation Index (LSI) reflected that majority of the samples have the tendency to form scale. The Karl Pearson correlation matrix has approved the maximum relationship of calcium and chloride with respect to the total dissolved solids (TDS). It is interesting to conclude that the groundwater in the study area has very hard nature, especially of non-carbonate type.
