ABSTRACT
Ground water samples were collected from different localities in and
around Karumandapam area, near koraiyar river, Tiruchirappalli
District, Tamil Nadu. Ten groundwater samples were collected and
analyzed for physico chemical parameter such as pH, Electrical
Conductivity (EC), Total Dissolved Solids (TDS), Biological Oxygen
Demand(BOD),Chemical Oxygen, Demand(COD),Calcium(Ca),
Magnesium(Mg),Total Hardness (TH), Bicarbonate (HCO3), and
Nitrate (NO3) in order to understand the different geochemical
processes affecting the groundwater quality. The analytical data were
compared with WHO. The analytical results indicate that the majority
groundwater samples are unsuitable for drinking purposes. The aquifers of the study area are
polluted due to the intersession of sewage are industrial effluents of fertilizers.
Keywords: Groundwater, physicochemical parameter, and water quality index.
