HYDROCHEMICAL ANALYSIS OF GROUNDWATER IN RASIPURAM TALUK, TAMILNADU, INDIAP. Mageshkumar, S. Anandakumar, M. Suresh and S. Ramesh
Subsurface water is an important source of drinking and irrigation water, especially for rural population in small city. Protecting groundwater from chemical contaminants is an important public-health concern. The result of a research study about the groundwater quality in Rasipuram Taluk, Tamilnadu, India, that took place during the period January 2013, is presented in this paper. Forty five sampling stations were selected and the samples were received from open wells, bore wells and PWD wells in the month of January 2013. The essence of the study is to evaluate the characteristics and quality assessment of groundwater in the area and variation in the groundwater quality during the post monsoon period. Most of the samples that were collected from the study area exceeded the IS limit, the parameters such as conductivity, turbidity, total hardness, sodium, iron and dissolved solids are the most dominated chemicals in the collected sample. The main reason for such contamination is the existence of more number of industries and dumping of waste by those industries. The usage of fertilizer also increases the contamination of groundwater. The water type in study area is mostly Mixed Ca-MgCl type and Ca-HCO3 type which was observed from the Piper diagram. The rainfall does not seriously change the groundwater quality but reduces the concentrations of parameters slightly.
