Abstract
Some physicochemical parameters related to groundwater quality obtained from Uppodai sub basin of Tambaraparani river basin of Tamilnadu was investigated for the purpose of drinking. Total 15 groundwater samples are collected from tube wells during the month of July 2013. In the groundwater samples analysed in physic properties and chemical characters such as pH, EC, TDS, major cations and major anions were measured using standard procedure. The physical properties values are varied from pH (7.4 to 8.9), EC (460 μmho/cm to 6100 μmho/cm) and TDS (294 to 3904). Similarly major ions Ca (72 to 416), Mg (2.44 to 112.24), Na (19 to 446), K (3 to 48), HCO3 (183 to 951), SO4 (7 to 168), Cl (142 to 525) and F (0.5 to 2.0) all parameters except pH and EC indicate the unite of mg/l. all the measured parameters compared with WHO (2011) standard for drinking water quality permissible limit. In this case the study area samples are occurred some samples above and below the limit, which is the affect the some anthropogenic activities.
