Correlation analysis of pysico-chemical properties of ground water in and around Malaiyeedu area near Kundaru river Pudukkottai district, Tamil Nadu, India

The present investigation is aimed to water quality for the ground water samples of Malaiyeedu area Pudukkottai district .Seven groundwater samples were collected and analyzed for some important physico- chemical parameter such as pH, Electrical Conductivity (EC), Total Dissolved Solids (TDS), Biological Oxygen Demand(BOD), Chemical Oxygen Demand(COD), Dissolved Oxygen (DO), Calcium(Ca), Magnesium(Mg), Total Hardness (TH), Bicarbonate (HCO3), Carbonate (CO3) and Chloride (Cl) were determined for water samples and the results were compared with standards prescribed by WHO. The study indicates that the water quality parameter such as EC, TDS, COD, BOD and Cl are exceeded the permissible limits. This result shows that the water quality of the study area is very poor and not suitable for drinking purpose. The correlation analysis provides an excellent tool for the prediction of parameter values within a reasonable degree of accuracy. This result was considered for correlation analysis and it was observed that many of the Physico- Chemical parameters bear a positive correlation and some bear negative correlation.
