Abstract:
The present work was undertaken to analyze the various water quality parameters, viz. pH, electrical conductivity, total dissolved solids, total alkalinity, total hardness, Cl-, SO4(2-), Ca2+, Mg2+, Na+ and K+ and study the WQI in bore well and dug well water samples. 30 water samples were collected from different localities of Virudhunagar district, Tamil Nadu (India). The results were compared with the values stipulated by World Health Organization (WHO), Indian Council of Medical Research (ICMR) and European Economic Community (EEC) for drinking water quality. The present study showed the overall water quality of Virudhunagar district is poor and unsuitable for drinking purpose which recommends the use of indigenous technologies, to make water fit for drinking purpose.
