The present study was carried out to determine the impact of the leachate contamination on water quality of Kolpu Khola nearby Sisdol landfill site. Water samples were collected from six different sites of Kolpu Khola from upstream to downstream. The samples were collected in clean plastic bottles from a leachate collection from December, 2007 to August, 2008 and analyzed for the determination of physical parameters (pH, conductivity, temperature) and chemical parameters (dissolved oxygen, alkalinity, chloride, calcium hardness, total hardness, BOD5, PO4-P, NO3-N, NH4-N) using a standard method. It was found that leachate was severely polluted with most of the physicochemical parameters being higher than the generic standard for industrial effluent discharged into inland surface water. The variation of BOD and COD showed that the chemistry of the leachate in the landfill was undergoing rapid change. The surface water of Kolpu Khola was not polluted from chloride point of view and the spatial variation of chloride content was significant at 0.01 significance level. The river water at all the sites under study had PO4-P above natural range i.e. 0.005 to 0.020 mg/l and was not suitable for livestock drinking and for aquatic animals with reference to most of the physicochemical parameters studied.DOI: http://dx.doi.org/10.3126/njst.v15i1.12026Nepal Journal of Science and TechnologyVol. 15, No.1 (2014) 107-114

Method Approach

The industrial sector is one of the important sector in supporting the development of a region. Utilization of land around the river that is used for industrial activities will affect the quality of river water. The river can be polluted by waste personinating from industries that operating around the river. The catchment area that used for industry, agriculture, urban development, and the use of land for making roads (gravel or footpaths) can affect the flow of surface water and sediments that it brings to the river. Waste generated from industrial activities can pollute rivers which are a source of water for daily needs and affect the development of biota in them. This can affect river water quality

Gomati River originate from Madhoganj Tanda village in Pilibhit district, U.P. it passes through the district of Shahjahanpur, kheri, Hardoi, Sitapur, Janpur and ultimately merge in Ganga. River water is significant for every living organism as well as aquatic life. Water pollution is a major global problem. Modernization and urbanization have polluted the river water and degraded the status. All over the world we are seeing that drain is the main source of water pollution especially for rivers flowing within the city. This drain generally carries industrial effluent, domestic waste, sewage and medicinal waste resulting in poor water quality. Gomati River receives industrial as well as domestic waste from various drains of Lucknow city. As Gomati river is the only source of surface water near the communities. A total 20 parameters namely Temperature, pH, Turbidity, Conductivity, Total dissolved solids (TDS), Total suspended solids (TSS), Total solids (TS), Dissolved oxygen (DO), Biological oxygen demand (BOD) Chemical oxygen demand (COD), Alkalinity, Total hardness, Calcium as ca, Magnesium as Mg, Chloride, Fluoride, Sulphate as So4, Nickel as Ni, Lead as Pb, and Zinc as Zn where analysed and their variation is discussed to obtain the impact of effluents on water quality. From the result it was found higher than the permissible limit of WHO and BIS.

Abstract Faecal contamination of surface water sources is an important water quality issue worldwide. Although quite a few studies exist on surface water faecal contamination and variability of indicator bacteria, most of the studies have been based on larger river basins and in temperate region. The variability is relatively unknown in local scale and in tropical developing countries. In this study we assess how anthropogenic and environmental factors affect faecal contamination and physicochemical parameters in Rupsha and Bhairab rivers around Khulna city, Bangladesh. Water samples were collected from six locations of the rivers during a wet and dry period in 2018 to measure Escherichia coli (E. coli) concentrations. Water physicochemical parameters—temperature, turbidity, pH, dissolved oxygen, biochemical oxygen demand and chemical oxygen demand were also measured. Higher concentrations of E. coli were found in the sampling sites located near the densely populated urban area compared to the downstream site, which receives fewer amounts of discharges from sewer drains. All the E. coli samples violated bathing water quality standards. E. coli concentrations were found to be correlated positively with precipitation and turbidity. A linear regression model was applied, that explains large part of the variation in E. coli concentration (R2 = 0.42). Water quality index assessment was also ranked the water quality as ‘poor’ category; indicate that the water is unsuitable for uses in domestic and recreational purposes and high health risks involved with the water use. The study findings highlight the problem of untreated sewage discharge into the rivers. Implementation of sewage treatment plant with adequate capacity is highly recommended.

The study was conducted to explore the physicochemical parameters of water, fish diversity andfisheries resources of Korotoa River at Bogura city of Bangladesh during July 2015 to February 2016. Thewater samples were collected from five sampling stations in the Korotoa River during wet and dry seasons.The results of the study showed that temperature, EC, TDS, DO, BOD, alkalinity, acidity and total hardnessof the Karotoa River water were 25.86ºC, 297.41 ?S/cm, 98.86 mg/L, 2.17 mg/L, 2.64 mg/L, 122.05mg/L, 3.28 mg/L and 75.59 mg/L, respectively. The DO and BOD contents of the river water were foundunsuitable for fisheries when compared with the standard of DoE. A total of ten fish species under six ordersand seven families were identified during the study period. The study also revealed that the most remarkablecause of water quality degradation of the river was waste dumping (58%) followed by urbanization and riverbank erosion. The water quality degradation (46%) negatively influenced the abundance of fish species. Theresults concluded that the water quality of the river is not favorable for production of fishes and other aquaticorganisms. The study suggested that the source of water quality degradation should be closely monitoredtogether with the industrial effluent and/or domestic sewage discharge should be reduced or stopped throughthe initiatives of the local government concerned to maintain sound and healthy ecosystem of the river.

Water quality issues are a growing concern due to the the recent intensification of urbanization and industrialization. This paper evaluates and compares the surface water quality of the ten sub-basins of the Pará River, located in the São Francisco River Basin, Minas Gerais, and evaluates the impact of seasonality and the compliance with the current limits of state legislation. The surface water quality monitoring database of the Institute of Water Management of Minas Gerais (Igam) was used, and 18 parameters were analyzed from a historical series from 2008 to 2016, totaling 16,651 observations. First, the descriptive statistics of the parameters were calculated, considering each sub-basin separately. Then, for the temporal and spatial analysis, the Kruskal-Wallis nonparametric statistical tests were applied, followed by the multiple comparison test, with an alpha level of 5%, due to the asymmetric behavior of the data. Thus, it was possible to compare water quality of the sub-basins in rainy and dry seasons and to identify which parameters were responsible for the greater degradation. In the compliance analysis to the current limits of state legislation, it was identified that all of the sub-basins were out of the specified range for at least one of the evaluated parameters. Finally, the seasonality analysis exposed significant differences in the parameters of dissolved oxygen, turbidity, total suspended solids, total solids and water temperature, where it was shown that there was a worsening of water quality in the rainy season for most sub-basins.
