Physico-chemical characteristics and correlation, and regression study on ground water of Coimbatore north zone.

ABSTRACT

Ground water samples were collected from 18 wards of Coimbatore City north zone, among which 2 samples were collected from 2 different locations from each ward, total 36 samples Water quality assessment was carried out for the parameters like temperature, odour, taste, colour, turbidity, pH, electrical conductivity, total dissolved solids, chlorides, hardness, alkalinity, calcium, sodium and potassium. Correlation coefficients were determined to identify the highly correlated and interrelated water quality parameters. Regression equations relating these identified correlated parameters were formulated. Comparison of observed and estimated values of the different parameters reveals that the regression equations developed in the study can be very well used for making water quality monitoring by observing the above said parameters alone. This provides an easy and rapid method of monitoring of water quality.
