Abstract

The physical and chemical properties of groundwater in Eloor, an industrial region, have been investigated to evaluate the extent of pollution. The study area was divided into four zones and a total of 40 water samples from different locations were collected, analyzed and correlation analysis has been carried out among the measured parameters. A comparison of the observed parameters with the limits prescribed by BIS revealed that in some area pH values are lower than the prescribed limit. The concentration of the major cations and anions were found to be significant. Magnesium and chloride exceed the desirable limit in some areas but less than the upper limit prescribed by BIS. Significant linear relationship was observed between pH, electrical conductivity, alkalinity, hardness, Ca2+, Mg2+ and chloride. The importance of these parameters in predicting the quality characteristics of groundwater is discussed.
