Hydrogeochemical characteristics of the shallow aquifer along a stretch of east coast in Cuddalore District, Tamil Nadu, India

Abstract

The hydro geochemical characteristics of groundwater were studied in the shallow aquifer along the east coast of Cuddalore district. Tamilnadu, India to identify the chemical processes mainly involved in affecting the quality of water present in the aquifers of the chosen study area. The water samples were gathered for conducting various tests from fifty borewells in the study area at every fortnight. The samples were tested and analyzed with the selected physiochemical properties such as pH, EC, TDS, and the major iron strength Ca, Mg, Na, K Cl, HCO3 and SO4. Interpretation of hydro geochemical data suggested that various ions with high concentration were present in the groundwater. But, it remains no change in the order of abundance for both cation and anion due to the seasonal effects. In fact, it was found that the characteristics of groundwater quality commonly mixed with sea water composition.
