Abstract

Hardness of water was understood to be a measure of the capacity of the water for precipitation soap. Soap is precipitated chiefly by the calcium and magnesium ions commonly present in water but also may be precipitated by ions of other polyvalent metals such as aluminium, iron, manganese and zinc. Therefore, determination of total hardness water content present in 16 public bore wells in the Pavagada taluk of Tumkur district, Karnataka State, India have been recorded for their appropriate usage as water quality parameter. The results clearly reveal that The obtained values were well within the range of permissible limits (10 mg/L) as per the WHO specification and hence suitable for human consumptions. Out of 16 villages the maximum turbidity value of 570.00 mg/L was found at K. T. Halli.

Keywords: Borewell water, physico-chemical parameters, total hardness.
