The weighted arithmetic water quality index method was used to assess the of anthropogenically-laden Anwai-river within Asaba-capital territory Delta State, Nigeria, in Stations 1(Otulu), 2(Isele- asagba) and 3(Anwai-Asaba) using pH, electrical conductivity (EC), total dissolved solids (TDS), biochemical oxygen demand (BOD), (DO), turbidity, phosphates, nitrates, hardness (TH) coliforms, determ...

The purpose of the paper is to assess the groundwater quality near the landfill sites using landfill water pollution index (LWPI). In order to investigate the scale of groundwater contamination, three landfills (E, H and S) in different stages of their operation were taken into analysis. Samples of groundwater in the vicinity of studied landfills were collected four times each year in the perio...

This study compares the Canadian Council Water Quality Index (CCME WQI) and Arithmetic (WAWQI) methodologies for determining quality of water in city Azogues (Ecuador). Additionally, a drinking risk index (IRCA) was determined to evaluate degree disease occurrence related consumption. The data generated came from analyses twelve physicochemical parameters (pH, turbidity, colour, total dissolved...

The hemipteran (Insecta) diversity in the upper part of the Kerian River Basin was low with only 8 families and 16 genera recorded at 4 study sites from 3 rivers. Water bug composition varied among sampling sites (Kruskal-Wallis χ (2) = 0.00, p<0.05) but was not affected by wet-dry seasons (Z = 0.00, p>0.05). All recorded water parameters were weakly associated with generic abundance but the bi...

This research developed a Water Quality Index (WQI) for public supply in the Vale do Rio Pardo Region, RS, Brazil (WQI-VRP), from database of 13th Regional Health Coordination, totaling 1175 samples. A filtration process resulted 285 samples with variables free residual chlorine, turbidity, apparent color, pH, fluoride, total coliforms and Escherichia coli. For water consumption purposes, by Sa...

fuzzy water quality index (fwqi) was applied in order to assess the degree of drinking water resources in yazd province, iran. thisstudy has also offered the creation of a new fuzzy water quality index (fwqi) to evaluate this tool’s applicability. 12 chemicalparameters including toxic and non-toxic heavy metals measured in 71 groundwater samples collected from drinking water resourcesin rural a...
