The Impact

Prevention of the surface water quality deterioration as a result of motorway construction or similar anthropogenic activities is certainly a rather more demanding task relating to watercourses with lower flow rates than larger watercourses. The paper presents the impact of part of the Banja Luka - Doboj motorway construction site, notably section 1: Banja Luka - Prnjavor, in Miloševci and Hrvaćani, on the Crkvena river water quality. The Banja Luka-Doboj motorway, with a length of 71.91 km, represents a key regional connection in the Republika Srpska, Bosnia and Herzegovina. It will connect the Gradiška - Banja Luka motorway (E-661) to Corridor 5c. Conducted sampling included the Crkvena river water, a right-bank tributary of the Vrbas river, in the Miloševci settlement, and at a new measuring point along the Crkvena River, at the culvert location in the settlement of Hrvaćani, near the motorway construction site. The goal of water sampling is monthly Crkvena river water quality monitoring in order to keep track of the of newly built motorway section's impact on this watercourse in the Miloševci settlement; the purpose of water sampling at a new measuring point in Hrvaćani is to control the Crkvena river water quality before the commencement of works at this location so that the impact of same on this watercourse could later be followed up. Comparison of the data acquired by continual monitoring of a significant number of parameters (total 18) during 12 months with their zero state, i.e. their values before the commencement of construction, gives a realistic overview of impacts of the construction site on the Crkvena river water quality.

Increasing migration of nutrients in the river water is a major factor in determining the quality of river water due to anthropogenic activities. In order to preserve the good water quality in rivers and other surface water bodies, it is necessary to take preventive measures that can be scientific water quality research and analysis. According to research carried out in kind, the article analyses the Anykščiai city as point source pollution, and the influence of it to the water quality of Šventoji river. Also, based on the statistical information a nutrient concentrations trend analysis of the meteorological and hydrological con-ditions influence was carried out. Investigations were carried out in July-September of 2016. Concentrations of ammonium (NH4-N), nitrite (NO2-N), nitrate (NO3-N), phosphate (PO4-P) and dissolved oxygen (O2) was analysed. In order to determine the impact of point source pollution on river water quality, the changes in concentration before and beyond Anykščiai city were evaluated, according to the meteorological and hydrological conditions. It was found that total nitrogen (Nb) and total phos-phorus (Pb) concentrations during the investigation period respectively, increases in 6% and 8%.

The Impact

Abstract In northern China, river water originating from or flowing through forests often contains large amounts of oxygen-consuming organic substances, mainly humic substances. These substances are stable and not easily biodegradable, resulting in very high detection values of chemical oxygen demand. However, under natural conditions, the dissolved oxygen demand is not as high. Using experimental values to evaluate river water quality and the impact of human activities on water quality is thus unscientific and does not meet national development goals. In this study, the potential sources of high-concentration chemical oxygen demand in river water in two areas exposed to virtually no anthropogenic activities and strongly affected by humic substances, were analysed. The chemical oxygen demand contributed by humic substances (COD-HSs) was quantified using three methods. The results of water quality monitoring in 2017 and 2018 revealed that the chemical oxygen demand concentrations (5–44 mg/L) predominantly exceeded the standard (15 mg/L). The study results suggest that COD-HSs should be considered separately for objective evaluation and management of water quality, particularly in areas that are seriously affected by COD-HSs, to provide a scientific basis for formulating sustainable water quality management policies.

This paper presents the application of the object-oriented framework SMILE to the management of flows and water quality in the Upper Mersey river catchment. The design river flows are those exceeded for 95% of the time, and are estimated applying alternative methods. The influence of compensation reservoirs, surface-water abstractions, and continuous discharges on low river flows is quantified. The annual licensed abstraction volumes are further reviewed. The monitored river water quality is classified using the River Ecosystem scheme. The compliance of the sewage treatment works and trade effluents with their discharge-consent limits is also assessed. The impact of effluents on the variation of river water quality is evaluated through Monte Carlo simulations at the discharge points. The points where the downstream water quality fails to comply with proposed River Quality Objectives are identified. The consent limits of the corresponding discharges are assessed, and changes to the BOD and total ammonia limits are suggested.

The Impact

Five years' experience with data of the TAILFER plant located 48 km downstream of the nuclear power site of GHOOZ is reported so as to provide guidelines for the examination of future nuclear cases. The factors considered are: the reduction in water flow and thermal impacts, the discharge of nuclear active effluents and the physico-chemical impact of enrichment in salts and suspended matter. Primary importance must be given to the proportion of the discharges in terms of added (instantaneous) volume activities. In the case of inland rivers the most active effluents, including the particular isotope tritium, are contained in a reduced volume (1400 m3/l000 MWe), and are best evacuated to other sites. Guidelines to check the river water quality are based on the measurement of 3H, total γ, and especifically, Go60, Cs13737, Mn54, Co58, and Cs134. Flow measurement and river transfer modelling must be part of the study of the impact as illustrated by this case-report.

Abstract The paper aims to understand how the public perceives river water quality and related risks and behaviour. Using the stratified semi-purposive sampling process, the study explores the perception of people residing along the river Yamuna in India. The method applied involved a structured questionnaire survey of 2706 respondents and four focused group discussions with people residing within two kilometres of the river bank. Non-parametric tests such as Kruskal Wallis, Mann Whitney U-test and One-Sample Wilcoxon Signed-Rank Test were used to analyse the data. The findings suggest that the majority of the respondents formulate their perceptions using non-scientific methods like sensorial and heuristics. Perception on sources of pollution is shaped by personal experiences and people do not perceive diffused sources of pollution that affect river water quality. Respondents attributed the pollution in the river to anthropogenic activities and their risk perception was found to be linked to their direct dependence on the river for their daily needs. The paper suggests behavioural change strategies to focus on social, governance, and technological drivers.
