ABSTRACT

Pamban bridge is a cantilever bridge that connect an island (Rameswaram) to the mainland (Mandapam) in Tamil Nadu, India. The objective of the present study is to examine the water quality parameters namely pH, electrical conductivity (EC), total dissolved solids (TDS), salinity (SAL), total alkalinity (TA), calcium hardness (CH), magnesium hardness (MH), total hardness (TH), chloride (Cl), and fluoride (F) at the extreme ends of the Pamban bridge for the year 2014. The Langelier Saturation Index (LSI) values confirm the corrosion tendency in most of the groundwater samples. The Water Quality Index (WQI) value proves the groundwater with potable nature though the area is seashore. The Principal Component Analysis (PCA) identifies the seawater intrusion by loading factors. The scatter diagram confirms the correlation of Cl with CH and TDS.

Keywords: Pamban, Water quality, LSI, WQI, PCA.
