| Abstract: | Ground water quality of Hisar city was assessed for its suitability for drinking purposes. Samples collected from the Bore-wells
(forms a part of municipal water supply) and handpumps (direct consumption) were analyzed for the various physico-chemical
parameters including pH, electrical conductivity, total dissolved salts, total hardness, total alkalinity, sodium, potassium,
calcium, magnesium, carbonate, bicarbonate, chloride and sulfate. The concentrations of magnesium, sodium, potassium, sulfate
and especially of chloride were found moderately higher than the WHO standards for the drinking water. Further a comparison
of fluoride (F−) levels in groundwater of various cities and towns of Haryana state was performed. The relatively higher concentrations of
F− in groundwater of Haryana raise the risk of fluorosis and hence groundwater must be used with proper treatment. Promising
defluoridation methods using locally available materials and technologies are discussed for the prevention and control of
fluorosis. Data were assessed statistically to find the suitable markers of ground water quality as an aid to monitoring groundwater
quality. |
