ABSTRACT
Groundwater samples were collected from different locations around Tiruchirappalli area and analyzed for their
physicochemical characteristics. Ten groundwater samples were collected from five Senthaneerpuram and five
from Sempattu for the period of December 2017. The present investigation is focused on the determination of
physicochemical parameters such as pH, Electrical Conductivity (EC), Total Dissolved Solids (TDS), Dissolved
Oxygen (DO), Total Hardness (TH), Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD),
Bicarbonate (HCO3), Calcium (Ca), Magnesium(Mg), Chloride (Cl-), Nitrate (NO3
-), Phosphate (PO4), Sodium
(Na), potassium (K) & Sulphate (SO4
2-). Groundwater suitability for domestic and irrigation purposes was
examined by using WHO and BIS standards. Thus, the objective of this study is to identify the quality of
groundwater especially in the Senthaneerpuram and Sempattu nearby area whether the groundwater is used for
drinking and domestic purposes.
Keywords: Groundwater, water quality index, physico-chemical parameters.
