Opis:

This paper aims to analyze the variability of the surface and ground water levels in Ambona peatlands. The depth at which the ground water table occurred was studied with reference to the adopted land drainage standards. The studies were carried out in 2009/10–2015/16 for natural and regulated water outflows. The analysis of annual total precipitation suggests that in the analyzed period some years were very wet (2009/10 and 2013/14), some were wet (2010/11, 2012/13 and 2015/16), one year was dry (2014/15) and one year was normal (2011/12). The 7-year average seasonal precipitation amounted to 598 mm, which was 71 mm higher than the average precipitation recorded in 30 years. The level of water in the river under adjustable outflow conditions ranged from 55 to 77 cm. The level of water under natural outflow ranged from 18 to 49 cm. In the area with adjustable outflow, the average draining depth was 47 cm. In the remaining area, not covered by the irrigation system, the draining depth was 64 cm. Additionally, the dynamics of variance in the water level under natural outflow conditions was clearly higher.

Opis:

In this paper, the degree of contamination of water was determined from anthropogenic reservoirs, located in the area of former coal mine Rozbark in Bytom. The physicochemical analysis of water indicated a high degree of anthropopression. In all analyzed reservoirs, permissible concentrations of chlorides and sulphates were exceeded. In the majority of them, the values of electrical conductivity and total suspended solids were also exceeded. In order to determine the transformation of surface water contamination, there was a comparison of archival data of water quality and laboratory tests performed after five years. Comparative analysis shows that in the last five years, there has been no improvement in the quality of the analyzed surface waters. In fact deterioration of the quality was noticeable.

Opis:

Steroidowe hormony płciowe, takie jak estron (E1), estradiol (E2) i etinylestradiol (EE2) są związkami, których obecność została w ostatnich latach stwierdzona w wodach naturalnych wielu krajów Europy. W środowisku wodnym pojawiają się one na bardzo niskim poziomie stężeń, ale na tyle dostatecznym, aby negatywnie wpływać na prawidłowe funkcjonowanie układu wydzielania wewnętrznego organizmów narażonych na ich obecność, powodując poważne zakłócenia procesów rozrodczych i rozwoju organizmów. W pracy przedstawiono wyniki wstępnej oceny obecności estrogenów w wybranych wodach rzecznych w Polsce. Jako metodę jakościowo-ilościowego oznaczenia estrogenów wykorzystano chromatografię gazową ze spektrometrią mas (GC-MS). We wszystkich badanych próbkach wód rzecznych stwierdzono obecność oznaczanych estrogenów, tj. estronu, estradiolu oraz etinylestradiolu.
Steroid sex hormones such as estrone (E1), estradiol (E2) and ethinylestradiol (EE2) belong to the compound group that has recently been determined in natural waters of many European countries. Normally, the concentrations of these compounds are very low in an aquatic environment but still sufficient to exert a harmful effect on the endocrine system functions in organisms exposed to estrogens. This results in a serious disorder of reproductive and developmental processes. The present paper includes data that enable the initial risk of estrogen contamination to be assessed for selected rivers of Poland. For the quantitative determination of these estrogens, use was made of gas chromatography/mass spectrometry (GC-MS) analysis method. Estrone, estradiol and ethinylestradiol were present in all of the water samples examined.

The article presents a short description of the municipalities, located in the immediate vicinity of the Biebrza River. They are: Lipsk, Sztabin and Nowy Dwor. The Biebrza Valley is an area of great natural significance, mainly due to its largest wetlands in Central and Western Europe. Their well-being depends mainly on the hydrologic conditions. Biebrza National Park and the area of the Upper Biebrza Basin, have been reported by Poland to the the Ramsar Convention, NATURA 2000, BirdLife International classification. Therefore, water, as a basic element of shaping the whole Biebrza Valley habitat is also protection subject, including constant monitoring of water quality. The aim of the article was to characterize the Upper Biebrza Basin which covers the area between the Sztabin Village and the Polish border with Belarus.

Opis:

The results of research conducted in recent years indicates that microplastic particles are widely distributed in the aquatic environment. The investigations are mostly focused on marine waters and there is still a lack of information about their presence in both surface water and groundwater. In this paper, preliminary results of research conducted in Poland are presented. Different types of water samples were collected. Five litres of each sample were filtered through 0.4 μm glass fibre filters. In the first stage, visual identification was conducted using a stereomicroscope. Additionally, some interesting fragments were examined by means of SEM/EDS method. In the case of rivers water samples, which were characterized by a high content of organic matter and minerals, the visibility of microplastics could be reduced. In the sample from the Vistula River, some particles similar to microplastics were found. In the groundwater samples, some blue and green particles which supposed to be plastic were found by the stereomicroscope. Additional analysis with the DXR Raman Microscope method gave no clear results. The samples were too small and the plastic particles were very dispersed which prevented correct analysis. SEM analysis showed irregularly shaped particles which were considered to be microplastics. Considering the chemical composition, carbon predominated.

Opis:

Water quality of seasonal water rivers is on a quick decline due to various human activities arising as a result of urbanization and population growth. This study assessed the water quality of the Khassa-Chai river in Kirkuk during two seasons: winter and summer (wet and dry). Thirty-seven water samples were collected from eight monitoring observation points along the Khassa-Chai river during October 2019 and March 2020. Water samples were analyzed for various parameters such as temperature, pH, electrical conductivity (EC), turbidity, total suspended solids (TSS), total dissolved solids (TDS), color, and dissolved oxygen (DO). These physicochemical parameters were analyzed using standards methods demonstrated by the American Public Health Association (APHA). To determine the significant difference, all the results obtained were statistically analyzed. In most results, higher concentrations are out of the indicated permissible limits of the World Health Organization (WHO). It can be concluded that the most domestic wastewater effluents are discharged into the river, such as sewage coming from nearby houses and restaurants in addition to the solid waste produced from close commercial stores. To reduce the negative impact on water and human health, pollution sources need to be properly managed. The paper calls for further research to figure out the ability of the Khassa-Chai river to make the use of city water in improving the environment.

Opis:

The water is invariably connected with village landscape. Ponds appeared not only inside villages but also on their edges. They fulfilled utilitarian function, the inhabitants used to water the cattle in them and used them in case of a fire. The neighbourhood of water-courses and also existing water reservoirs was taken by location into consideration. Sometimes new ponds were created on the base of the rivers. They were located inside, on the edge of villages and also as an inseparable element of the parks close to manors and palaces. During the last century the number of water surfaces was considerably on the decrease, however at present people started to appreciate their value again. The former utilitarian function of the retainer water surfaces changed into decorative, recreational or fishing ones. It is alarming that ponds disappear gradually from the country area. The part of the neglected ones dry up because of the lowering of the level of the underground water, but a lot of ponds disappear because of the purposeful activity of man. In the place of the covered ponds new recreational areas arise or they are designed for building areas. At the same time they small ponds are placed on private properties, which confirms the natural needs of the people to commune with water. However, we may show a lot of the interesting examples of the development of water surfaces as regards both the landscape and the use. For the inhabitants of Pietna village in Krapkowice commune the existing ponds and the river are of the main value, which is the base for the new projects exhibiting the unique character of the village.

The study aimed at the evaluation of the quality of bottom sediments and evaluation of potential threat to the aquatic environment. Cadmium, cobalt, chromium, copper, nickel, lead, zinc and mercury concentration in the separate layers of the sediments in the pond at Żelisławiec decreased with the depth of bottom sediments. On the other hand, the highest concentrations of the studied elements occurred in the deepest layer of sediments in the pond at Stare Czarnowo. The level of the potential ecological risk (PER) for the sediments of the Żelisławiec pond classifies them as sediments with low quality of the potential ecological risk, whereas the sediments from the pond at Stare Czarnowo are classified as moderate level of the potential ecological risk. In both ponds, the highest I_geo values were reported for zinc and lead.

Opis:

The surface water quality assessment could be based on a combined physical and chemical analysis, but it could also be determined with bioindication methods. Classical physicochemical analysis is in most cases more expensive and time-consuming than the bioindication methods. This type of analysis also requires expensive equipment and shows the situation in the water only at the moment of sampling. Although the bioindication methods are often complicated, they allow a relatively inexpensive estimation of the water quality. Moreover, during their implementation, the substances harmful to the environment are not generated, and the obtained results usually reflect the total interaction of all factors and substances to the analyzed living organisms. Indicator organisms or their communities applied to the research, with identified ranges of tolerance to selected factors, could help to determine the physical and chemical parameters of water. This paper presents a bioindication study with an effect of stormwater system on the receiver – the Bystrzyca river, in Lublin, Poland. The level of saprophyty of the river sector was calculated based on the selected species of algae (diatoms and green algae) and the influence of the stormwater discharge on the communities of these organisms was determined.

Opis:

The environment is considered an ideal machine, a system in which nothing happens without reason. Every transformation, action and stimulus has consequences that are not always immediately plain to see. It is because the environment is like communicating vessels, or a complex organism, in which everything is interdependent, and the organs work together. Despite the processes’ complexity and intricate yet logical correlations between the elements, it is not a perfect system. Examples are weather anomalies and, in extreme cases, cataclysms. The problem arises when man interferes with the environment. By polluting almost every possible place, he initiates irreversible changes, degrading the environment. This paper presents an analysis of atmospheric air pollution in the town of Supraśl, surface water from the Supraśl river, and soil samples from a selected area.

Opis:

The study presents the characteristics of the Mściwojów Reservoir equipped with a unique pre-reservoir structure that supports the process of self-purification of waters. The authors present more than ten years of studies, focusing mainly on the issues of water quality and the concentration of phosphorus, which is considered as the main factor influencing water eutrophication process. Quite a high concentration of phosphates was noted in the outflow from the main reservoir, in spite of a lower concentration of these compounds in the water leaving the pre-reservoir. Basing on the conducted analyses, the catchment of the reservoir was qualified as group 4, being very prone to the movement and supply of material to the reservoir. The negative value of the retention coefficient of phosphorus obtained for the main part of the reservoir points to the existence of an internal source of phosphorus supply to the reservoir. During over 10 years of studies, new directions of the development of the rural areas were determined. Future works should be extended so as to cover all elements of the ecosystem of the reservoir. In a longer term it seems natural to extend the research works to cover the whole catchment of Wierzbiak River.

The article presents results of analyses of selected chemical indicators of the bottom depo sit taken from the Raszynka River, its tributaries and several ponds located in the catchment. Reaction (pH) of the sediments was mostly neutral or slightly acidic – optimum for the growth of aquatic flora and fauna. Mineral sediments with small admixtures of organic matter prevailed. Concentration of total nitrogen and sorption capacity depended on the content of organic matter in the sediments. The analysis indicate that contamination of the bottom sediments does not exceed standards.

Opis:

The catchment area of Oued Larbaâ is located in the eastern prerif at the very eastern end of the large Innaouene basin, a stream of Oued Sebou [Lahrach. A et al., 1994]. The objective of the study was to establish a quality comparison of the watershed during the dry and wet seasons. Eight water and sediment samples were taken during the two seasons, all along the main channel of the Larbaa river, taking into account anthropogenic activities and the areas of confluence with its tributaries: Tarmasst, Taza, Larouireg, Defali and Jaouna. The physicochemical parameters (pH, EC, TDS, nitrates, sulfates, chlorides), as well as metal contamination (Al, Zn, Ni, Pb, Ag, Fe, Cd, Cr, Cu, Mg, Mn) were studied in summer. The results revealed the alkaline pH higher than 7, a significant electrical conductivity in several stations, but still conforming to the Moroccan standards. Laboratory analyses reflect that the waters of the basin have generally good quality, except for a few peaks that indicate metallic contamination in Fe and Al. In order to better assess whether there is an anthropogenic effect influencing these results, and to remove the relationships between the different parameters studied, a statistical analysis was carried out with the PCA tool. This analysis made it possible to indicate Cr, Ni and Al as indices of pollution in certain areas. Although the results obtained have been tolerant until now, it is necessary to put in place an action plan to control the areas at risk of contamination during the years.

Monitoring leachate, groundwater and surface water aiming to determinate the concentration of heavy metals (Hg, Zn, Ni, Cr⁺⁶,Cd, Pb) at the municipal solid waste landfill Štěpánovice took place in the years 2002–2010. The values of heavy metals concentration oscillated as follows: Zn (0.05 – 0.37 μg/ dm³), Cr⁺⁶ (0.01 – 3.3 μg/dm³), Hg (0.0001 – 0.001 (μg/ dm³), Ni (0.001 – 0.19 μg/ dm³, Cd (0.001 – 0.007 μg/ dm³) and Pb (0.002 – 0.176 μg/dm3). The measured data show that the concentrations of heavy metals met the limits provided by law. Under the current landfill operation mode, the results of measurements do not indicate any negative impact on the quality of surface water, groundwater or leachate water.

Zaostrzające się wymagania stawiane wodzie powierzchniowej ujmowanej do zaopatrzenia ludności oraz wodzie przeznaczonej do spożycia zmusiły do poszukiwania metod poprawy jakości wody. W pracy scharakteryzowano pogarszającą się jakość ujmowanej wody powierzchniowej ze Zbiornika Sulejowskiego na przestrzeni ostatnich 10 lat i jej wpływ na technologię oczyszczania, trudności w dotrzymaniu obowiązujących norm jakościowych oraz koszt oczyszczania wody. Omówiono rozważane w Zakładzie Wodociągów i Kanalizacji w Łodzi kierunki działań, zmierzające do poprawy jakości wody. Przedstawiono etapy zastąpienia ujmowanej wody powierzchniowej wodą podziemną, a także dostosowanie technologii i urządzeń do oczyszczania najpierw wody zmieszanej, a następnie samej wody podziemnej. Omówiono efekty technologiczne i ekonomiczne zastąpienia wody powierzchniowej na podziemną w systemie wodociągu "Sulejów-Łódź".
The object under study was the Water Supply System Sulejów-Łódź, which provides the city of Łódź (over million inhabitants) with drinking water. The water is drawn from an impoundment lake (Sulejów). In the past 10 years, the quality of the lake water has been deteriorating and fails to meet the more and more stringent standards. The continuing deterioration has also had a detrimental effect on the treatment and the costs involved. All this triggered the search for an alternative approach. Thus, in their effort to upgrade the quality of the treated water, the Waterworks of Łódź decided to use deep-well water instead of surface-water intakes. Such substitution requires adaptation of the treatment train and relevant equipment to the two stages of transition: the first one involving a mixture of both surface water and groundwater, and the second one using deep-well water alone. In conclusion, the paper itemizes the technological and economic benefits of switching from surface water to deep-well water treatment.

Opis:

The study aimed to evaluate the influence of seasons and tides on surface water quality of Hau River in Hau Giang province, Vietnam. The water quality data were collected at six locations at low tide and high tide. The monitoring parameters included pH, dissolved oxygen (DO), biochemical oxygen demand (BOD), chemical oxygen demand (COD), total suspended solids (TSS), ammonium (NH4+-N), nitrate (NO3--N), orthophosphate (PO43--P), total phosphorus (TP), total nitrogen (TN), iron (Fe) and Coliform. One-way analysis of variance (One-way ANOVA), cluster analysis (CA) and discriminant analysis (DA) were applied to determine the influence of tides and seasons on water quality. The surface water quality was compared with the national technical regulation on surface water quality in column A1 (QCVN 08-MT:2015/BTNMT). The results showed that surface water in the study area had organic pollution and high eutrophication potential. The BOD, COD, TN, TP, Fe and coliform parameters in low tide tended to be higher than those in high tide. Five parameters, including TSS, TP, TN, PO43--P and coliform had a significant difference between the wet season and the dry season by DA analysis. Cluster analysis classified the water quality into three clusters, mainly by the BOD, COD, TSS, PO43--P and Fe parameters. The study provides important information on the water quality of the Hau River in the Hau Giang province for water uses and monitoring.

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.

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 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 surface water table level is a crucial factor for the existence of wetland habitats, and valuable from the point of view of environmental protection. In particular, surface water table in a hydrological year play an important role, affecting the seasonal changes in conditions of the development of species inhabiting a given patch of vegetation. The occurrence of floods often determines the possibility of survival of a given plant community. Information on the seasonal variability of surface waters, and above all the range of seasonal floods, is very important from the point of view of planning protection activities in National Parks in order to preserve wetland habitats. Nowadays, remote sensing data is an important source of spatial information, particularly those characterized by low cost data acquisition and processing. One such source is imagery collected from satellites, along with products freely distributed by the European Space Agency. Satellites of the Sentinel constellation provide multi-spectral optical remote sensing images recorded at visible and infrared wavelengths. Due to the short satellite revisit time of the Sentinel, the images from this satellite constitute a potential source of information for the monitoring of moisture on wetlands with a high temporal resolution. In this study, the authors aim to demonstrate the possibilities associated with the use of satellite images to monitor the range of a free surface water table in the pilot area located within the basin of the Łasica Channel, located in the Kampinos National Park (Poland). The accuracy of the results of the remote sensing transformations will be assessed using high resolution RGB images obtained with the use of unmanned aerial vehicles (UAV) and control points measurements. The maps of free water table has been acquired as an result of ensemble regressors (Random Forest, Extra Trees, Bagging). Regressors has been learned and applied for two sessions. Promising results were obtained indicating the possibility of using the proposed method on a similar scale.

In the paper there is presented an evaluation of variability of surface water quality (reservoirs and watercourses), on the area of degraded post-mining area in Bytom. The physicochemical analysis of water and compared with archival data obtained in 2009 and 2014. There were done analysis of following parameters: reaction, total content of substances dissolved in water, water hardness and the content of: Cl-, SO42-, HCO3-, Ca2+, Mg2+, K+, Na+, NH4+, NO3-, NO2-, PO4- ions as well as Fe and Mn. The examined surface waters were characterised by high content of solutes. Anions were dominated by chlorides, the sodium proved to be the dominating cation, the examined water samples were characterised by high concentration of sulphates. In all analyzed reservoirs, permissible concentrations of chlorides and sulphates were exceeded. In all sample points there was observed a decrease of pH value in long term period, the concentration of chlorides lowered, however concentrations of sulphates increased in the majority of sampling points.

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:

Several conjunctive use approaches can be distinguished. Drought cycling of groundwater (GW) usage and storage relies on more surface water (SW) during wetter years and delivers more water from GW during drought years. This method has the benefit of temporal changes in water availability. Additionally, it is usually desirable in areas with internal variability of SW where surface storage of wet-year surpluses is uneconomical, suffer excessive evaporative losses, or cause unacceptable environmental disruption. In previous studies, the purpose of operating the drought cycling was to reduce operating costs. In these studies, the objective function of the proposed model was to minimise the present value cost derived from the system design and operation to satisfy a predefined demand during a finite planning and operation horizon. However, it is important to consider other objectives in operating water resources systems, including minimising water shortages accurately. Hence, in this study, two scenarios were focused on: 1) mi-nimising water shortagages, 2) minimising operational costs. Pareto solutions are then presented with the objectives of minimising costs and water deficit. In this study, the weighting method has been used to extract Pareto options. The results show that reducing costs from 234 to 100 mln USD will increase water shortage from 9.3 to 11.3 mln m3.

Noctiluca scintillans is an important member of the mesozooplankton in terms of biomass and production in the Seto Inland Sea, Japan. The densities and adenosine triphosphate (ATP) contents of N. scintillans cells were measured. Vertical profiles of N. scintillans cellular activity in the coastal water were determined and the ATP contents were high at middle layers, with a maximum depth of 10 m. ATP contents were low in the surface and lower layers. These results suggest that active N. scintillans cells in subsurface layers with low density play an important role in the coastal ecosystem, and high-density cells in the surface water are not active.

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.

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:

Nadmiar związków fosforu w wodach powierzchniowych prowadzi do wzrostu żyzności wód, a co z tym związane wykluczenia ich z użytkowania gospodarczego, rekreacyjnego czy przyrodniczego. Wykorzystanie materiałów reaktywnych, czyli materiałów posiadających zdolność do selektywnego usuwania określonych substancji na drodze sorpcji lub wytrącania, daje możliwość usuwania fosforu ze ścieków i innych źródeł a także zanieczyszczonych wód stojących i płynących. Celem pracy jest charakterystyka procesu decyzyjnego przy wyborze materiału reaktywnego służącego do usuwania fosforu z wody i ścieków, na przykładzie kruszywa Pollytag®. Lekkie kruszywo popiołoporytowe Pollytag® powstaje przez granulowanie i spiekanie popiołu lotnego w temperaturze 1000–1350 °C. Badania laboratoryjne wykazały, że materiał ten charakteryzuje się dobrymi zdolnościami sorpcyjnymi (32,24 mgP-PO₄•g^-1) i może być zastosowany do usuwania fosforu z roztworów o wysokich stężeniach (powyżej 10 mgP-PO₄•dm^-3). Zdolności sorpcyjne materiału muszą być potwierdzone w testach kolumnowych i terenowych.
The surplus of phosphorous in surface water leads to increasing its productivity, and makes the water unable for economic, recreational and natural use. One of the method for removing phosphorus from water bodies is to use reactive materials, which are referred as adsorbents or sorbents and specially interact with targeted chemical species such as phosphate ions. The aim of this study is to characterize the decision-making process of selection of reactive material for removing phosphorus from water and wastewater, on the example of lightweight aggregate Pollytag®. The lightweight aggregate Pollytag® is made by granulation and sintering of fly ash in temperature of 1000–1350 °C. Laboratory tests showed that Pollytag® is characterized by good sorption (32,24 mgP-PO₄•g^-1) and can be used as a phosphorous reactive material for high concentration of phosphorous (above 10 mgP-PO₄•L^-1). Sorption capacity of reactive material should be verified by column and full-scale experiment.

Opis:

Celem pracy było określenie źródeł zanieczyszczeń wód powierzchniowych i wybranych metod ich usuwania. Wody powierzchniowe zanieczyszczane są poprzez substancje migrujące z gleb oraz poprzez spływ powierzchniowy i podpowierzchniowy. Źródłami antropogenicznymi są melioracje komunikacja, rolnictwo i inne. Jedną z metod oczyszczania wód z jonów amonowych jest stosowanie metody wymiany jonowej z użyciem zwietrzeliny bazaltowej. Natomiast związki ropopochodne skutecznie mogą być usuwane metodą ultrafiltracji.
The aim of this study was to identify sources of pollution of surface water and some pollutant removal methods. Surface waters are contaminated by substances migrating from the soil and by surface flow and subsurface flow. There are other sources such as transport, land melioration, etc. One of the method of ammonium ion removal from the water is ion-exchange method using basaltic rock-mantłe. However oil-related compounds can be effectively removed by ultrafiltration.

W pracy przedstawiono wyniki badań koagulacji objętościowej w wodzie z rzeki Biała Nida w przekroju Żerniki. Celem badań był dobór dawki i udziału składników mieszaniny koagulantów. Przeprowadzone badania obejmowały dobór koagulantu pod kątem usuwania z wody zanieczyszczeń nadających jej barwę i mętność oraz ustalenie optymalnej jego dawki. Wyznaczono dawki optymalne dla koagulantów glinowych i żelazowych oraz oddzielnie dla mieszaniny powyższych koagulantów przy pomocy planu rotatabilnego. Wykazano wyższość mieszaniny FeCl3 z Al2(SO4)3 nad samym tylko koagulantem glinowym lub żelazowym. Stwierdzono, że o stopniu usuwania zanieczyszczeń współdecydowały rodzaj i dawka koagulantu
The paper presents the test results of volumetric coagulation in water from Biała Nida taken in Żerniki. The aim of the research was to determine the dosage and composition of the mix of coagulants. The scope of the investigation covered the selection of the coagulant in view of removing from water contaminants that cause certain colour and turbidity. Determination of the optimal dosage of coagulant was also covered in the investigation. The optimal dosages of aluminum and iron coagulants were determined as well as of the mix of the mentioned coagulants using the rotatable plan. Better properties were found for the mix of FeCl3 and Al2(SO4)3 in comparison to the single aluminum or iron coagulant. It was proven that the level of the removal of contaminants was influenced by the kind and dosage of the coagulant.

Opis:

The paper deals with the influence of oils on surface water pollution. Two mineral oils of petroleum origin, one synthetic oil and one vegetable oil were tested. Properties of the selected oil types were assessed by ecotoxicological tests. The acute toxicity test on Daphnia magna showed that out of the tested oils the most toxic for these aquatic organisms were the petroleum oils. In the phytotoxicity test on Sinapis alba, the toxic effect of mineral oils in comparison with synthetic and vegetable oil was more significant. Oils create oil stains visible under the microscope. It was difficult to differentiate them from Scenedesmus subspicatus. The calculation of growth rate was not relevant and a significant loss of cells was detected. It follows from the summary of the tests results that vegetable oil is the least aggressive for the aquatic environment and there are no significant differences between synthetic and mineral oils.

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.

Polish accession to the European Union has given Poland an access to many supporting mechanisms which came out of the Common Policy. We received financial support in the form of EU funds for environment protection and agriculture. Between 2004-2006 the “Plan of Rural Area Development” was implemented, its priority was the reconstruction and modernization of substantial elements of the water drainage facilities. After 2006 the Program of continuation was established, to continue the investments activities started between 2004- 2006, as a “Rural development Program for 2007-2013” (pol. PROW), a sort of complementation of activities in agricultural water resources management. In 2008 the Regional Inspectorate for Environmental Protection in Białystok has performed an assessment of 52 rivers in Podlasie in terms of water quality in 69 gauging-control section. The results showed that: 7.8% of water is in good ecological condition (II class), 51.6% are in moderate ecological condition (III class), 3.1% is in low ecological condition (IV class). Among researched uniform parts of water there was no water in bad ecological condition (V class). The objective of this work is the assessment of impact of the investments financed by Rural development Program, on surface water quality in Podlasie. This article is also up to present the financial support of EU, aimed to increase the investments for the environmental protection.

The research was carried out in the laboratory of the Tyumen Industrial University. The analysis of samples for the content of oil products was carried out by the fluorometric method on a fluid analyzer “Fluorat-02–2M”. The results of the study indicate the need to monitor surface waters and toughly respond to insufficient compliance with the standards for the protection of surface waters and bottom sediments within the city of Tyumen.

Opis:

The aim of the study was to use regenerated activated carbon to adsorb phenol from a river. Coconut shell activated carbon was derived from used tap water filter cartridges. The activated carbon was carbonised and then activated with KOH at 200°C, under a nitrogen atmosphere. The resulting adsorbent was characterised on the basis of nitrogen adsorption by Brunauer-Emmett-Teller (BET), scanning electron microscopy (SEM) analysis and point of zero charge (pH PZC). The study of periodic adsorption included kinetic and equilibrium modelling, determined the effect of solution pH on efficiency and the possibility of regeneration and reuse of the adsorbent. The efficiency of phenol removal from model water was evaluated, followed by the possibility of their adsorption from a polluted river in Silesia Province. Phenol adsorption followed pseudo-second-order kinetics. The adsorbents showed high adsorption abilities, as determined by the Langmuir isotherm model. The model fits the experimental data well. The concentration of phenol in the river was in the range of 0.45-0.77 mg∙dm-3, which means that its value was at least five times higher than the standard values. The use of regenerated activated carbon from waste filter cartridges removed phenol from the river by 78% using optimal test parameters.

Opis:

The monitoring that was carried out at the landfill specialized in leachate, groundwater and surface water. There were 6 sampling sites. The observed parameters were pH, BOD₅, COD_Cr, conductivity. Leachate reached the high values in all observed parameters. Groundwater samples were collected at two monitoring wells and the sampling site (A, B, C). Surface water was collected from two sampling sites (D, E). The pH showed slightly acid values at all sampling points. The pH of surface water was slightly acid to neutral. Both BOD₅ and COD_Cr values remained stable over the reporting period. The average conductivity value at sampling points D, E remained constant. In line with the Czech National Standard ČSN 75 7221 “Classification of Surface Water Quality” sampling point D belongs to II Water Quality Class – slightly polluted water and sampling site E to Class I water quality – unpolluted water. The authors believe that the fluctuations occurring with regard to the values of certain samples were not caused by the operation of the landfill itself, but were a result of the intense agricultural activity nearby the landfill.

Opis:

The study aimed to assess the variation in surface water quality in the Tien Giang province, Vietnam, and at the same time identify the main sources of water pollution. The surface water quality samples were collected at 34 locations (NM01-NM34) with 17 surface water quality indicators in March, June, September and November in canals and rivers in the Tien Giang province. Multivariate statistical analysis methods, including principal component analysis (PCA), cluster analysis (CA) and numerical discriminant analysis (DA), were used to analyze the variability and key indicators affecting the effect of multivariate statistical analysis. The analysis results show that the surface water quality in the study area is contaminated with organic (low DO, high BOD and COD) and nutrients (NH4+-N, NO2--N, PO43--P and TP), salinity (high Cl-). The PCA results showed that 14/17 surface water environmental parameters to be monitored are pH, temperature, TSS, BOD, COD, NH4+-N, NO2--N, PO43--P, TP, SO42-, Cl-, coliform and Fe. The PCA analysis showed that PC1-PC4 accounted for 79.70% of the variation in surface water quality in the study area. Potential surface water polluting sources include hydrological regime, domestic waste, agricultural production, industrial production activities. The CA results showed that 34 monitoring locations can be reduced to 27 locations, with a frequency of 4 times/year to ensure surface water quality representativeness. The DA indicated that the indicators of EC, SO42- and Cl- made the difference of the surface water quality between the wet and dry seasons. The current results provide important information on the current state of water quality for different uses and contribute to the improvement of the surface water quality monitoring system in the Tien Giang province.

Opis:

Water quality along the Waratah Rivulet in the Woronora Lake Catchment, New South Wales (NSW), Australia, has been monitored during the last three years by the Sydney Catchment Authority. Water quality data shows changes in chemical composition due to cracking of streambeds and rockbars, and diversion of surface water into subsurface routes in the Hawkesbury Sandstone aquifer. Water quality upstream of the longwall panels is comparable to nearly pristine water in creeks and rivers flowing in similar sandstone bedrock environments and to limited water quality data collected prior to mining. A segment of the Waratah Rivulet, where subsidence and cracking of streambeds and rockbars has occurred, is causing surface water to be redirected into subsurface fracture systems, mix with groundwater already present in the aquifer and partially reappear downstream. This subsurface flow in the shallow fractured sandstone aquifer causes the chemical composition and water quality to change as an effect of water–rock interactions. Salinity, iron, manganese and many cation and anion concentrations increase, whereas oxygen is significantly depleted. Mobilisation of barium and strontium from the rock mass indicates fast chemical dissolution reactions between the subsurface flow and carbonate minerals. Other metals mobilised include zinc, cobalt and nickel. Subsurface water partially discharges from underground receptors downstream of the area impacted by longwall mining. The discharged water is rapidly oxidised by atmospheric oxygen, causing precipitation of iron and manganese oxides / hydroxides out of solution. Hydrogeochemical modelling indicates the dominant iron minerals precipitated out from the water are in this environment goethite, lepidocrocite and ferrihydrite. The paper discusses changes in surface water and groundwater chemistry due to subsurface flow and water–rock interaction, the hydrogeochemical processes responsible for changes in water chemistry, as well as changes in water quality along the rivulet.

Monitoring of surface waters within the transboundary section of the Western Bug River showed, that during 2014–2018, a significant excess of the maximum permissible concentration (MPC) was observed for some substances for fish ponds. As a result of this, the water in the river for these substances was rated as “dirty” in terms of purity and corresponded to water quality class IV, namely: phosphorus was observed to exceed the MPC at the observation point Ambukіv village in 2015 (9.7 times), for manganese – an excess of the MPC at the observation point Ambukіv village in 2018 (9.7 times) and in point Zabuzhzhia village in 2014 (7.9 times), 2015 (8.0 times), 2017 (7.1 times), 2018 (8.3 times); for the total iron – the exceeding of MPC at the observation point Ambukіv village in 2016 (5.95 times) and 2017 (6.13 times); at the observation point Ustilug town in 2016 (5.23 times); in the observation point Zabuzhzhia village in 2016 (9.44 times) and 2017 (5.27 times). The assessment of the surface waters based on the determination of the pollution factor showed that during the study period their quality did not deteriorate but did not meet the norms. In general, surface waters of the river correspond to the second class of quality and are characterized as “poorly polluted” waters by the level of pollution.

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.

Opis:

The household and industrial wastes that have been accumulated during the last 40–50 years organized and spontaneous landfills (garbage dumps) pollution of the natural water bodies near locations. As results of precipitation and solar irradiation, the drainage of water formation occurs; such waters are polluted with harmful and toxic ingredients. The known indices of pollution of industrial and surface waters as well as the technique for determining the class of danger posed by solid household wastes were analyzed. The application of this technique to liquid wastes is suggested, since the change of aggregate state must not restrict its application; on the contrary, a new useful unexpected result can emerge with this. A rather simple dimensionless index of toxicity was chosen on the basis of the following examples: composition of the drainage waters of a specific landfill, content of harmful ingredients in them, excess ratio of their maximum permissible concentration. Such an index takes into account the maximum permissible concentration of the harmful substance in the ground, as well as the fraction of the harmful ingredients in the total mass of the liquid waste. Using the dimensionless index of toxicity, the bar charts were drawn, from which the sequence of removal of harmful components from the liquid mixture can be determined, starting with the component with the least value of dimensionless index of toxicity which characterizes the most dangerous component.

Opis:

Several sea and laboratory experiments have been carried out to detect and determine the fluorescence characteristics of seawater and its natural fluorescing components and to analyse the influence of oil in the surface water layer on the lidar-induced return signal. The aim of the laboratory investigations was to create a database of different natural water types and of water polluted with Petrobaltic oil. During the r/v ‘Oceania’ cruise in the southern Baltic Sea two lidar methods were applied simultaneously to detect and analyse the influence of the fluorescence emission of oil on the fluorescence spectrum of seawater. Detection of oil pollution can be used to correct the fluorescent factors of fluorescing components on the basis of natural seawater fluorescence spectra.

Opis:

Wody z rzeki Mała Panew w miejscowości Czarnowąsy oraz z ujęcia Czaniec w miejscowości Kobiernice, wraz z symulacjami, w których osady denne tych wód wymieszano z ich matrycami naturalnymi, poddano badaniom fizyko-chemicznym. W ten sposób określono wpływ porywania osadów dennych podczas okresów dynamicznego przepływu wód rzecznych na ich parametry w tym co było głównym celem pracy: OWO, RWO, absorbancje przy długości fali 254 nm, SUVA₂₅₄, zasadowość, stężenie wybranych metali: glinu, żelaza i ołowiu. Następnie wody te poddano procesowi koagulacji. Dawki koagulantów określono przy pomocy analizy punktu izoelektrycznego zanieczyszczeń koloidalnych, przy czym wartym odnotowania jest, iż nie zaobserwowano wpływu porywania osadów na konieczność zwiększenia dawki koagulantów. Koagulację prowadzono przy pomocy 2 rodzajów koagulantów: koagulantu wstępnie zhydrolizowanego oraz klasycznego koagulantu hydrolizującego. Wykazano wzrost stężenia zanieczyszczeń organicznych i nieorganicznych po ekstrakcji osadów dennych do wód surowych. Zanieczyszczenia te występowały głównie w formie zawiesiny. Wykazano również większą efektywność procesu koagulacji przy zastosowaniu koagulantu wstępnie zhydrolizowanego Flokor 1,2A w stosunku do siarczanu glinu przy zastosowaniu zdecydowanie niższej dawki tego pierwszego. Badania te wykazały również negatywny wpływ siarczanu glinu na odczyn i zasadowość wód uzdatnionych.
The waters from Mała Panew river in Czarnowąsy and from Czaniec water intake in Kobiernice, together with simulations, in which bottom sediments of this waters mixed with its natural matrixes, were subjected to physicochemical analysis. In this way, the influence of rivers bottom sediments entrainment during dynamic waters flow periods on its parameters (including TOC, DOC, UV absorbance, SUVA254, alkalinity, metals concentrations: aluminium, iron and lead) was determined, which was the main purpose of this study. Subsequently, the waters were subjected to the coagulation process. The coagulant doses were determined by colloidal pollutions isoelectric point analysis. It is noteworthy that there is no influence of sediments entrainment on the necessity to change the coagulants doses. The coagualtion process was carried out with 2 types of coagulants: prehydrolyzed coagulant and conventional hydrolyzing coagulant. An increase in the organic and inorganic matters concentration after river sediments extraction was presented. However, it mostly comprised suspended matter. It has been also shown that prehydrolyzed coagulant Flokor 1.2A has a better efficiency in water coagulation process in relation to aluminium sulphate, even at much lower doses . Studies have also shown the negative influence of using aluminium sulphate on the pH and basicity of the treated waters.
