Abstract The monitoring of selected physicochemical parameters and chemical composition of water was conducted in 2017-2018 in the Lubrzanka river and the Cedzyna reservoir (Swietokrzyskie Mountains, Poland). The results indicate that the impact of reservoir on the quality of river water depends on natural characteristics of the catchment as well as on the present anthropogenic pressure. Retention of water in the reservoir caused seasonally diversified changes in analysed parameters, including an increase in water temperature, retention of major ions, nutrients and trace elements. Further research is needed to assess the risk of contamination of lower course of the river with metals deposited in reservoir’s bottom sediments.

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

Abstract Sewage discharge is considered to be the primary source of viral contamination in aquatic environments. This study was conducted to evaluate the impact of El-Rahawy wastewater on the water quality of the Rosetta branch of the River Nile (Rosetta River Nile) through detection of astrovirus (AstV) and norovirus (NoV) in the water and sediments of both sites. For this purpose, we collected 72 wastewater and 12 sediment samples from El-Rahawy drain, and 12 river water and 12 sediment samples from Rosetta River Nile before and after mixing with El-Rahawy wastewater between April 2017 and March 2018. AstVs and NoVs were identified in wastewater (40.2% versus 25%), El-Rahawy sediment (41.6% versus 20.8%), river water after mixing with wastewater (25% versus 16.6%), river water before mixing with wastewater (8.3% versus 0%), river sediment after mixing with wastewater (16.6% versus 8.3%), and no viruses were found in river sediments before mixing with wastewater. AstV genogroup B and NoV genogroup GI were the most frequently detected genotypes in the analyzed samples, with a peak incidence in the winter months. Increasing detection rates of both viruses in El-Rahawy drain samples and river water taken from the Rosetta branch after receiving El-Rahawy wastewater reflect the impact of this drain on the water quality of this stretch of the River Nile.

Abstract. Summarizing the scientific publications and production reports of enterprises that studied the environmental status of the Prut River in the last decades, as well as relevant reports in the periodical press and other media, it has been found that the quality of its water in the upper reaches is significantly deteriorating. The purpose of this article was to assess the quality of water in the Prut River in the upper flow according to various methods (including the complex of environmental indexes) to determine the degree of its pollution. The article presents the results of calculations of the complex ecological index (Ie) for assessing the water quality of the Prut river in the vicinity of the city of Yaremche. To establish sources of pollution of this river, an experimental study of the physical and chemical parameters of its water was carried out. A series of water samples from the Prut River in the area from the village Dora (suburb of Yaremche). upstream to the village Tatariv is studied laboratoryally. Samples were selected at six points of observation. The studies were conducted in two seasons: fall (september) and winter (january). The main pollutants and their concentrations in the selected samples are determined. Modern laboratory techniques and equipment are used for laboratory research. On the basis of laboratory examination of water samples from the river Prut in the upper reaches (the outskirts of the city of Yaremche) it was established that the water in this area is sufficiently clean; excess MPC value is not observed. An exception may be only a sample of water within the city of Yaremche, where there are increased concentrations of phosphates. It is also shown that winter water samples contain slightly more pollutants (including biogenic ions) than autumn. These facts may also be partly explained by the increase in airborne acid oxide emissions and their interaction with river water. According to the results of calculating the complex ecological index it was established that the Prut River water in the studied area belongs to the 2nd class of quality (the state is good). Separate samples from the control section within the city of Yaremche showed an increased value of the complex ecological index (Ie is 3.21 and 3.36 for the summer and winter series, respectively). The reason for this increase in the index is the pollution of the Prut River in the studied area due to the increase in anthropogenic pressure on it over the past years.

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.

Groundwater Quality Index

The aim of this study was to propose a groundwater quality index (GWQI) that presents water quality data as a single number and represents the water quality level. The development of the GWQI in agricultural areas is vital as the groundwater considered as an alternative water source for domestic purposes. The insufficiency of the groundwater quality standard in Malaysia revealed the importance of the GWQI development in determining the quality of groundwater. Groundwater samples were collected from thirteen groundwater wells in the Northern Kuala Langat and the Southern Kuala Langat regions from February 2018 to January 2019. Thirty-four parameters that embodied physicochemical characteristics, aggregate indicator, major ions, and trace elements were considered in the development of the GWQI. Multivariate analysis has been used to finalize the important parameters by using principal component analysis (PCA). Notably, seven parameters—electrical conductivity, chemical oxygen demand (COD), magnesium, calcium, potassium, sodium, and chloride were chosen to evaluate the quality of groundwater. The GWQI was then verified by comparing the groundwater quality in Kota Bharu, Kelantan. A sensitivity analysis was performed on this index to verify its reliability. The sensitivity GWQI has been analyzed and showed high sensitivity to any changes of the pollutant parameters. The development of GWQI should be beneficial to the public, practitioners, and industries. From another angle, this index can help to detect any form of pollution which ultimately could be minimized by controlling the sources of pollutants.

Aims: The aim of this work is to know the interrelationships of the physicochemical parameters likely to explain algal blooms and to identify the potential structures of molecules that can be secreted in an Ivorian lagoon environment: the Ebrié lagoon. Methodology: Nine stations, selected according to natural influences and anthropogenic pressure, were subject to physicochemical monitoring. It consisted of in situ measurements (temperature, salinity, dissolved oxygen, electrical conductivity) and chemical analyses in the laboratory (pH, nitrates, nitrites). In addition to these measurements, observations were noted in the field, namely the climatology of the day, the colour and smell of the water, the presence of algae (micro and / or macroalgae). Results: Our results showed that the waters of the Ebrié lagoon are warm (T > 25 °C), with a pH between 6 and 9 and variable salinity. Salinity would be a discriminating factor for the presence of macroalgae. The nutrients levels (nitrates and nitrites) remain within the limits of acceptability. Conclusion: The waters in our study area are favorable for algal blooms. Given the nuisances associated with algal blooms, the study proposes some structures of toxins which can be secreted on the basis of a literature review.

The Impact

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
