title: Water quality aspects of some wells, springs and rivers in parts of the Udhampur District (J & K).
abstract: Water samples were collected from wells (9 Nos.), springs (11 Nos.) and rivers/streams (6 Nos.) during pre and post monsoon seasons in the months of June and October 1999, respectively. Various physico-chemical parameters and trace elements (viz., Cu, Mn, Zn, Co, Fe, Ni, Cr and Pb) were analysed to evaluate drinking water quality on the basis of BIS and irrigation water quality on the basis of salinity, sodicity, residual sodium carbonate, and concentration of toxic elements. The study showed alkaline nature of surface and ground water. Calcium and magnesium are dominating cations and bicarbonate is major anion in the study area. At some locations the concentration of TDS, Mg, Ca, total hardness, Fe, Mn and Cr exceeded the limits set up for drinking purposes. Water quality evaluation for irrigation purposes on the basis of SAR values indicates excellent category of water.
