Applicability of heber water quality index-1 [Hwqi-1] on ground water collected from Trichirappalli area

During the past several decades, ground water quality has emerged as one of the most important and confronting environmental issues. In this present investigation, ground water quality of water samples collected from the wells of 10 selected places in and around pulivalam, an area located about 35km away from the Rockford city; Tiruchirappalli has been assessed using the Heber Water Quality Index-1(HWOI-I), a novel and indigenous statistical analysis. The parameters analyzed were Temperature, pH, Total Solids, Turbidity, Dissolved Oxygen, Biochemical Oxygen Demand, Fecal Coliform, and Fluoride. The total HWQI –I values, for all the samples are in the range of 40.5-53.5. These values suggest that almost all the water samples are bad in quality and not recommended for drinking and domestic uses. In addition to the total HWQI-1 values, proper attention has been paid to each individual parameter.
