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.
分别于1999年6月和10月的季风季节前后，从水井（9口）、泉水（11处）和河流/溪流（6条）采集了水样。分析了各种理化参数和微量元素（即铜、锰、锌、钴、铁、镍、铬和铅），以根据印度标准局（BIS）评估饮用水质量，并根据盐度、碱度、残留碳酸钠和有毒元素浓度评估灌溉水质。研究表明地表水和地下水呈碱性。钙和镁是主要阳离子，碳酸氢根是研究区域的主要阴离子。在一些地点，总溶解固体（TDS）、镁、钙、总硬度、铁、锰和铬的浓度超过了饮用水设定的限值。基于钠吸附比（SAR）值的灌溉用水水质评价表明水质为优良等级。
