Opis:
The study area of the Nida valley was examined to investigate variations in groundwater and surface water levels, as well as the interaction between them. In the valley, there were three branches. The two actives were the Nida River itself and the Smuga Umianowicka branch while the Stara Nida branch was dry during the measurement session. Over a 12-month period from June 2021 to June 2022, 7 monitoring points were equipped with piezometers, comprising 5 groundwater points and 2 surface water points. The monitoring frequency was set to 30 minutes. The results of this research indicate that there are significant differences in the water level at the same observed point at different times. This study demonstrates seasonal changes in both surface water and groundwater levels with higher levels in autumn and winter and lower levels in spring and summer, which are closely tied to the changes in meteorological conditions during the research period, such as precipitation and air temperature. The study results also indicate that during summer and winter at the Nida River and its riparian area, losing stream is the primary process occurring in the studied reach. Conversely, during autumn and spring, the main process is gaining stream. At the human-maintained Smuga Umianowicka branch and in its riparian area, losing stream is the main process during summer and autumn, and gaining stream is the main process during spring. During winter, losing stream and gaining stream processes can occur simultaneously, and neither process takes place mainly.

Opis:
The research analyzed seasonal changes of the oxygen regime and related indicators on the example of water objects of the Ukrainian Polesie Region. The region shows different directions of economic use. Zebrafish (Danio rerio Hamilton–Buchanan) and the Prussian carp (Carassius auratus gibelio Bloch) were used as test objects to investigate survival responses. Dissolved oxygen (DO) concentration in water, pH values and temperatures were determined by standard methods. Based on research results, the main problems were determined pertaining to the oxygen regime of investigated waters, i.e. the increase in temperature and toxicity of the aquatic environment in the summer. A rather dangerous decrease in DO concentration, almost up to the levels of maximum allowable concentration (MAC) (4.10 mg∙dm–3 in group E1 and 6.07 mg∙dm–3 in group E2), was observed in August and it was typical for the reservoirs with a slow water movement. Flowing river waters (group E3) were eliminated due to their better aeration compared to other groups. The correlation analysis based on the presented data revealed a high and average degree of probable correlation between the DO concentration and water temperature, as well as an average degree of correlation with general toxicity determined on sensitive species of D. rerio, and in group E1 on the persistent species C. auratus gibelio as well. The interrelations and equations of the rectilinear regression can be used to predict the oxygen regime of the waters investigated and other surface waters having similar problems.

Opis:
Water quality is an environmental priority for irrigation in rainfed agriculture. Recently, water quality has been affected by the uncontrolled disposal of wastewater, the use of chemical fertilizers in agriculture and, most significantly, by the excessive exploitation of water resources during the low season. The basin of the Maffragh in the Algerian north-east real is fed by two main rivers: Wadi El Kebir East and Bounnamoussa. From its source, the stream is continually contaminated with domestic and agricultural discharges through the tributaries causing a significant deterioration in water quality. In order to know the current state of water quality in the Maffragh basin and to determine its suitability for irrigation without any prior treatment, research has been conducted in the two streams at representative sampling points in catchment areas used for irrigating crops. To assess the quality of water and detectable compounds monitoring, laboratory methods are used. The various volumetric and colorimetric assays were carried out according to Jean Rodier. Organic parameters such as nitrites, ammonium and phosphates, were measured using a UV/VIS 6705 JENWAY spectrophotometer, at wavelengths of 543 nm, 630 nm and 880 nm respectively for nitrites, ammonium and phosphates. The BOD5 and COD parameter was measured using a DIN EN 1899-1-H51 spectrophotometer and DIN ISO15705: 2002 spectrophotometer. The performed analyses on conductivity shows oscillating values ranging between 425 and 495 μS∙cm–1 for January 2018, while for the low water level of July 2018 the conductivity varies between 433 and 796 μS∙cm–1; this parameter is determinant for water quality assessment and its use for irrigation. Beside the conductivity test, the Riverside–Wilcox diagram was applied, to combine conductivity and sodium absorption rate (SAR). The obtained results of the two seasons show satisfactory results in the applicability of the water to irrigate in the basin.

Opis:
In this work, the studies of various physico-chemical parameters of surface waters originated from the selected area of oil exploitation in the south of Poland are presented. The water samples were collected from streams and ponds or directly from surface tanks situated in the vicinity of operating wells. The observed values of different parameters like pH, odór, color, turbidity, electroconductivity, concentration of sulfate, chloride, nitrate, iron, calcium, magnesium, ammonium, alkanity, dissolved oxygen or petroleum contamination of samples were compared with standard values recommended by the WHO (World Health Organization) and the relevant Polish Regulation. Preliminary studies show that investigated surface waters are slightly affected by anthropogenic pollution. The main two sources of contamination of water from the study area are agriculture and mining industry.

Opis:
The implementation or optimization of the coagulation process requires prior preliminary tests. Standard Jar-Test method is time-consuming, inaccurate and may not work well, especially for the waters characterized by high variability of quality parameters. Zeta Potential Isoelectric Point (IEP) analysis may give fast and precise data on the coagulant type and dose required for maintaining an efficient coagulation process. The research objects included the surface waters taken directly from the Mała Panew and Odra rivers. The zeta potential and set coagulant dose dependence was measured for each sample. Four aluminum-based coagulants with different characteristics were used in this research: aluminum sulfate (Alum), polyaluminum chloride (PAC), dialuminum chloride pantahydroxide (PACl), polyaluminum chloride hydroxide sulfate (PACS). Charge neutralization effectiveness, by means of Zeta Potential IEP analysis, was the basis for the choice of the most effective coagulant doses. The coagulation process efficacy was based on the parameters of the treated water (pH, turbidity, color, alkalinity), reduction of organic matter (Abs254, Total Organic Carbon (TOC), Dissolved Organic Carbon (DOC)) and residual aluminum contamination. The Zeta Potential utility evaluation was based on the DOC reduction.

Opis:
The interaction between groundwater and surface water plays an important role in the function of riparian ecosystems and sustainable water resource management. Hydraulic fracturing, an unconventional oil and gas well stimulation method, has increased dramatically in North America in an effort to exploit previously inaccessible shale oil and gas reserves. Hydraulic fracturing often requires several thousand cubic meters of water to fracture the source formations. Use of such a high volume of water has raised considerable public concern over the sustainability of this activity and the potential impacts on surface water and groundwater. This paper provides a review of the published literature addressing the effects of water withdrawal for hydraulic fracturing on surface water and groundwater. The potential effects of such withdrawal are: decreased volume of water in rivers, streams, lakes and aquifers; alteration of natural flow regimes; regional water shortages during periods of drought; creating conflicts with other water users in water-stressed regions; inadequate downstream water availability; reduced downstream water quality for human uses, due to less water availability for dilution; and degradation of habitat and aquatic ecosystem function, impacting local wildlife. This review demonstrates that relatively little attention has been paid to quantify and understand these interactions, and suggests that there is a significant need for further research in this area to address the currently limited availability of data.

The article describes modern anthropogenic load on the surface water of the Southern Bug River Basin in a changing climate. The main water users-pollutants of the Southern Bug River Basin in Vinnytska and Mykolaivska regions were identified. The water quality of the surface water of the Southern Bug River in time and space (along the river stream) was analyzed. The water quality of the Southern Bug River was assessed by complex indices for different water users. In order to assess water quality, it is recommended to use complex indices that take into account the effect of the total action of pollutants. The self-purification potential and capability of restoration in space (along the river stream) of the aquatic ecosystem of the Southern Bug River was established for 2019. The results of the study allow us to state that the use of surface water of the Southern Bug River Basin for drinking, fishery, cultural and recreational needs is related to certain environmental risks. It is recommended to carry out the environmental protection measures aimed at adjusting the priorities of economic activity, reduction of wastewater discharge and increase in the water content of the river by regulating the operation of energy complexes.

Opis:
Developments in agriculture, industry, and urban life have caused the deterioration of water resources, such as rivers and reservoirs in terms of their quality and quantity. This includes the Saguling Reservoir located in the Citarum Basin, Indonesia. A review of previous studies reveals that the water quality index (WQI) is efficient for the identification of pollution sources, as well as for the understanding of temporal and spatial variations in reservoir water quality. The NSFWQI (The National Sanitation Foundation water quality index) is one of WQI calculation methods. The NSFWQI is commonly used as an indicator of surface water quality. It is based on nitrate, phosphate, turbidity, temperature, faecal coliform, pH, DO, TDS, and BOD. The average NSFWQI has been 48.42 during a dry year, 43.97 during a normal year, and 45.82 during a wet year. The WQI helped to classify water quality in the Saguling Reservoir as “bad”. This study reveals that the strongest and most significant correlation between the parameter concentration and the WQI is the turbidity concentration, for which the coefficient correlation is 0.821 in a dry year, and faecal coli, for which the coefficient correlation is 0.729 in a dry year. Both parameters can be used to calculate the WQI. The research also included a nitrate concentration distribution analysis around the Saguling Reservoir using the Inverse Distance Weighted method.

Opis:
River-lake systems comprise chains of lakes connected by rivers and streams that flow into and out of them. The contact zone between a lake and a river can act as a barrier, where inflowing matter is accumulated and transformed. Magnesium and calcium are natural components of surface water, and their concentrations can be shaped by various factors, mostly the geological structure of a catchment area, soil class and type, plant cover, weather conditions (precipitation- evaporation, seasonal variations), land relief, type and intensity of water supply (surface runoffs and groundwater inflows), etc. The aim of this study was to analyze the influence of a river-lake system on magnesium and calcium concentrations in surface water (inflows, lake, outflow) and their accumulation in bottom deposits. The study was performed between March 2011 and May 2014 in a river-lake system comprising Lake Symsar with inflows, lying in the Olsztyn Lakeland region. The study revealed that calcium and magnesium were retained in the water column and the bottom deposits of the lake at 12.75 t Mg year-1 and 1.97 t Ca year-1. On average, 12.7±1.2 g of calcium and 1.77±0.9 g of magnesium accumulated in 1 kg of bottom deposits in Lake Symsar. The river-lake system, which received pollutants from an agricultural catchment, influenced the Ca2+ and Mg2+ concentrations in the water and the bottom deposits of Lake Symsar. The Tolknicka Struga drainage canal, to which incompletely treated municipal wastewater was discharged, also affected Ca2+ and Mg2+ levels, thus indicating the significant influence of anthropogenic factors.
