Water quality index and suitability assessment of urban ground water of Hisar and Panipat in Haryana.

Ground water quality in two well-developed cities of Haryana, viz. Hisar and Panipat was assessed for drinking purpose based on water quality parameters like pH, EC, turbidity, TDS, alkalinity, total hardness, calcium (Ca), magnesium (Mg), sodium (Na), potassium (K), chloride (Cl), nitrate (NO3), phosphate (PO4), sulphate (SO4) and fluoride (F) with respect to different land-use areas viz. residential, industrial, commercial and agricultural. Water quality index based on 9 parameters showed that at Panipat, underground water in all the land-use zones was fit for consumption (WQI < 50), whereas at Hisar, water in agricultural areas was good in quality, but that in other areas varied in magnitude of pollution (WQI > 50 to 100).
