Study on the physico-chemical characteristics of ground water of Bidar city and its industrial area.

The present work is aimed at assessing the ground water quality characteristics of Bidar city and its industrial area. The groundwater samples of all the 35 wards were collected and subjected for a comprehensive physicochemical analysis. The following 17 parameters have been considered viz., pH, total hardness, calcium, magnesium, chloride, nitrate, sulfate, total dissolved solids, iron, fluoride, sodium, potassium, alkalinity, manganese, dissolved oxygen, total solids & zinc. The results analyzed by Correlation and Regressions, have been used to suggest models for predicting water quality. The analysis reveals that the groundwater quality status of the study area is good, but it also needs to be protected from the perils of contamination by giving certain degree of treatment.

Studies on water quality index of ground water of Aland Taluka, Gulbarga District, Karnataka.

Water Quality Index is one of the most effective tools to communicate information on the quality of ground water to the concerned citizens and policy makers. The objective of the present work is to assess the suitability of ground water for human consumption based on the computed water quality index values, ground water characteristics and quality assessment. Ten villages of Aland taluka are selected and at each village water samples at three places were collected using standard procedural methods and analyzed for pH, TH, Ca, Mg, Cl, TDS, Fe, F, NO3, SO4.
