Weighted arithmetic water quality index method was used to find WQI along the stretch of the river basin. It was observed from this study that the impact of human activity and sewage disposal in the river was severe on most of the parameters. In current study, Water Quality Index (WQI) was calculated by using the Weighted Arithmetic Index method as described by. In this model, different water quality components are multiplied by a weighting factor and are then aggregated using simple arithmetic mean. The first step in calculation of WQI following ‘weighted arithmetic index’ method involves the estimation of ‘unit weight’ assigned to each physico-chemical parameter considered for the calculation. By assigning unit-weights, all the concerned parameters of different units and dimensions are transformed to a common scale. Weighted arithmetic water quality index method classified the water quality according to the degree of purity by using the most commonly measured water quality variables. The method has been widely used by the various scientists [ 44 , 45 , 46 , 47 ] and the calculation of WQI was made [ 48 ] by using the following equation: In this study, the WQI, which is calculated using the weighted arithmetic index method [21] is used to determine the effect of waste dumping on the immediate ground and surface water- bodies to the dumpsite, as it is deemed the most appropriate, based on the prevailing conditions.

Un-weighted Arithmetic Water Quality Index (WQI UA) is calculated to diminish the huge data to one numerical value that expresses the overall water quality [24] . In this research, Un-weighted Arithmetic Water Quality Index (WQI UA ) was computed to evaluate suitability of groundwater for drinking and irrigation purposes.
In this study are discussed various water quality indices used to assess the quality Weighted Arithmetic Water Quality Index Method classifies the water quality
11 Oct 2019 Halda River; Pollution Sources; Water Quality Index; Water Pollution The calculation of the WQI can be performed by using the weighted index method. The Weighted arithmetic water quality index (WQIA) is calculated by water quality index have been calculated by use of Weighted Arithmetic Index Method: Weighted arithmetic water quality index method classified the water. Weighted arithmetic water quality index method was used to calculate the WQI . The study was carried during September and December (2016). The WQI values Nitrates(Spectrophotometric method) tests were performed. 3.3 Calculation of Weighted Arithmetic WQI. Weighted arithmetic water quality index method. calculated by using Weighted Arithmetic Index method as explained by [29]. According to this method, different water quality parameters are multiplied by a 25 May 2012 The calculation of Water Quality Index (WQI) was carried out using software on the world sanitation website weighted arithmetic index method WATER QUALITY INDEX IN AND AROUND BADVEL TALUKA. D. Janardhana Rao et This was derived by weightage arithmetic method. It is one of the most
