Abstract

After going through Hadagada dam, Agarpada, and Bhadrak town, the river Salandi joins the river Baitarani near Akhandalmani, the Tinitar Ghat. Forest runoff, untreated and semi-treated mining wastes, agricultural wastes, Ferro Alloys Corporation (FACOR) industrial wastes, and urban wastes are all collected during the journey. Water samples were collected from nine different stations in the summer (April and May), rainy (August), post-rainy (October), and winter (December) of 2015, and physico-chemical and bacteriological parameters were examined using standard protocols. The weighted arithmetic index approach was used to determine the water quality index (WQI) of river Salandi using the mean values of twelve significant parameters over the course of the year. The water quality index (WQI) reveals that water quality varies by monitoring station, with good water quality at Hadagada Dam, Satabhauni, and Dhusuri, poor water quality at Akhandalmani & very poor water quality at Bidyadharapur, very poor and unfit for drinking water at Agarpada, Randia (FACOR), and Baudpur, and river water of class ‘C' at Rajghat. The river after passing Bhadrak town is free from pollution. It is due to dilution and by natural processes where the pollutants are stabilized.
印度奥里萨邦哈达格达大坝萨兰迪河及其下游至Akhandalmani的水质指数调查与评价
经过Hadagada水坝、Agarpada和Bhadrak镇后,Salandi河在Akhandalmani (Tinitar Ghat)附近与Baitarani河汇合。森林径流、未经处理和半处理的采矿废物、农业废物、铁合金公司(FACOR)的工业废物和城市废物都在旅途中收集。2015年夏季(4月和5月)、雨季(8月)、雨后(10月)和冬季(12月)在9个不同站点采集水样,采用标准方案检测理化和细菌学参数。采用加权算术指数法,利用12个重要参数的年平均值确定了萨兰迪河的水质指数。水质指数(WQI)显示,不同监测站的水质不同,Hadagada大坝、Satabhauni和Dhusuri的水质良好,Akhandalmani的水质较差,Bidyadharapur的水质很差,Agarpada、Randia (FACOR)和Baudpur的水质很差,不适合饮用,Rajghat的河水为“C”级。经过巴德拉克镇后的河流没有污染。这是由于稀释和污染物稳定的自然过程造成的。
