Water quality of Gomati river water in and around Sultanpur of Uttar Pradesh, State, India

The physico-chemical characteristic of the natural Gomati river draining the Sultanpur (U.P.) are studied vis-s-vis to the urban effluents.An ionic dominance patteren of Ca++ < Mg++ < Na+ < K+ : HCO3 < -SO- in river water and Ca++ < Na+ < Mg++ < K+ : HCO3 < - Cl < -SO -4 in effluent water was recorded. The effluent water registered increase in variable amounts of biogenically active PO-3 P and in all the ionic species. The level of alkalinity, hardness, BOD, COD, DOM and WQI also depicted a response similar to the ionis spectra. However, the DO was significantly lower in the polluted water samples. Seasonal variations in various factors are illustrated in relation to percental water quality indices.
