Opis:
The sorption of divalent copper, natural sorbents of kaolinite and montmorillonite clays and carbon sorbent was studied on model solutions under static conditions. Quantitative characteristics of sorption process of copper ions were obtained. The degree of extraction of copper ions from solution was investigated, depending on the concentration of the initial solution and the weight ratio of the sorbent and volume of treated solution. The magnitude of sorption increases along with the increase in the volume of copper sulfate solution with a concentration of 0.02 M at a constant sample of sorbents. A higher carbon sorption capacity of the sorbent, in relation to ions of copper, was compared to kaolinite and montmorillonite clay. A higher sorption capacity of the carbon sorbent with respect to copper ions is established in the comparison with kaolinite and montmorillonite clay.

Opis:
Poland’s third largest city, Lodz, underwent rapid industrial and demographic growth in the 19th and 20th centuries, followed by a steep decline over the last three decades. This paper describes how the water supply system has been adapted over the last century to meet these challenges, and in particular how the source of water (surface or underground) and structure of the supply system has been adapted to maintain drinking water quality. The Lodz water supply has been managed since 1925 by the firm Zaklad Wodociagow i Kanalizacji Sp. z o.o. The water supply system was designed by the Englishman William H. Lindley (in 1909), but because of World War I and the global depression that followed work began only in 1934. After World War II further deep wells were constructed, followed by a pipeline network and treatment plant. A 50-kilometre pipeline bringing surface water from the Pilica River was completed in 1955, followed by the Sulejowski Reservoir on the same river (1968–1973). Algal blooms on the reservoir presented a major challenge, and deep wells were turned to as a solution. By 2010 Lodz had 58 deep well intakes, so that in 2013 it was no longer necessary to take taking surface water from the Sulejowski Reservoir.
Projekt łódzkiej sieci wodociągowej, wykonany przez najlepszego europejskiego fachowca W. Lindleya, powstał już w 1909 r. Realizację rozpoczęto w 1934 r., przy współudziale polskiego inżyniera S. Skrzywana. Po II wojnie światowej dokonano wiercenia dalszych studni głębinowych i zbudowano system wodociągowy oraz stację uzdatniania wody. Zbudowano 50 km rurociągu Tomaszów–Łódź (1955 r.), zbiornik retencyjny na Pilicy (1968–1973) i kolejne studnie głębinowe. W 2010 r. istniało już 58 ujęć wód podziemnych dlatego też w 2013 r. zapadła decyzja o rezygnacji z ujmowania wody powierzchniowej z Zalewu Sulejowskiego. Celem pracy było przedstawienie miejsc pobierania wody i struktury sieci wodoci ągowej, której budowa ulegała zmianom w zależności od potrzeb i rozwoju dużego miasta, w powiązaniu z uzyskiwaniem wody pitnej najwyższej jakości. Piecze nad eksploatacją i dystrybucją nieprzerwanie od 1925 r. sprawuje Zakład Wodociągów i Kanalizacji Sp. z o.o. w Łodzi.

Opis:
In order to solve the problem of providing the population with high-quality drinking water, preference is given to the use of groundwater deposits, which differ from surface sources in better quality and are more protected from man-made influences and climate change. Thirty-seven existing groundwater deposits are used for drinking and technical water supply in Lviv region. The distribution of groundwater in the region is very uneven, and in the Eastern Carpathians they are almost non-existent. The main factors of groundwater pollution in most of Ukraine are municipal sewage, livestock effluents, unorganized warehouses for storage of industrial waste, fertilizers and pesticides and other local objects that affect the state of groundwater. The gradual reduction of mineral fertilizer and pesticide usage has led to some improvement in the quality of groundwater, but for some agro-industrial areas the presence of residual pesticides and nitrogen compounds in groundwater remains a relevant problem. This year, there was an increase in the use of mineral fertilizers compared to last year. The aim of this work was to study the compliance of the maximum allowable concentrations of hydrochemical parameters of the wells of the Stryi water intake and to determine the potential impact of anthropogenic factors on water quality. The compliance with the sanitary and hygienic requirements of the hydrochemical parameters of water in the wells of the Stryi water intake was analyzed. The regularities of their changes as well as the presence of wells that have a potentially unstable chemical composition and are prone to deterioration of water quality were determined. The results of studies of related to the impact of self-treatment processes in the river Stryi on the quality of water intake in the city of Stryi showed that the drinking water from artesian wells is of high quality and now there are no negative effects of river water in the Stryi basin on groundwater deposits. The quality of river water is satisfactory for its use in domestic and drinking water supply and for recreational purposes.

Opis:
It is known that groundwater is an indispensable element without which we cannot think of life on our planet. It is also known that around 50% of the world's population uses drinking water sources to meet the existential needs. Increment of population, industrial development and environmental pollution in our globe, directly or indirectly, has not only impacted groundwater pollution, but has also contributed in reducing the amount of water needed to meet elementary needs of man and other living beings. Therefore, for humanity, proper monitoring of groundwater became a priority in order to identify pollution levels and prevention of potable water sources from eventual contamination. Although Kosovo has sufficient water reserves, in most villages in the absence of infrastructure, the rural population in most cases for the purpose of providing drinking water uses water wells and springs. For this very reason, we have assessed the quality of the water wells located in the central part of Kosovo, in the village Kopiliq of Skenderaj. To assess the water quality of these wells, we have set the monitoring network, based on five monitoring points (wells), determining the organoleptic, physico-chemical parameters and bacteriological characteristics. Obtained sample results were compared with the reference values of Directive 98/83/EC – for drinking water quality and some wells resulted in exceeding the reference values for nitrite, chloride and total dissolved solids (TDS) whereas all wells were highly contaminated with bacteria.
Wiadomo, że wody gruntowe są elementem niezbędnym do życia na naszej planecie. Wiadomo także, że 50% populacji świata korzysta z ujęć wody pitnej dla zapewnienia swoich potrzeb egzystencjalnych. Wzrost liczby ludności, rozwój przemysłu i zanieczyszczenie środowiska na Ziemi przyczyniają się, pośrednio bądź bezpośrednio, do zanieczyszczenia wód podziemnych i do ograniczenia ilości wody potrzebnej do zaspokojenia elementarnych potrzeb człowieka i innych istot żywych. Z tego powodu właściwy monitoring wód podziemnych stał się priorytetem niezbędnym do identyfikacji poziomu zanieczyszczeń i do zapobiegania ewentualnym zanieczyszczeniom źródeł wody pitnej. Choć Kosowo posiada wystarczające zasoby wodne, wobec braku infrastruktury, w większości wsi ludność wykorzystuje studnie i źródła do pozyskania wody pitnej. Kierując się tymi przesłankami, autorzy wykonali ocenę jakości wody studziennej w centralnej części Kosowa we wsi Kopiliq koło miasta Skenderaj. Utworzona została sieć monitoringu opartą na pięciu stanowiskach (studniach) i oznaczyono właściwości organoleptyczne, parametry fizyczne i chemiczne oraz bakteriologiczne wody. Wyniki analiz porównano z wartościami referencyjnymi Dyrektywy 98/83/EC dla jakości wody pitnej. W niektórych studniach stwierdzono przekroczone wartości stężenia azotanów, chlorków i sumy substancji rozpuszczonych (TDS). Wszystkie studnie były silnie zanieczyszczone bakteriami.

Opis:
Assessment of drinking water quality in seven largest Latvia drinking water supply systems (Riga, Daugavpils, Liepaja, Ventspils, Jelgava, Jurmala, and Rezekne) in 2008 using mathematical statistical processing of chemical composition data is carried out. In all analyzed drinking water the concentrations of Hg, Cd, Pb, Cu, Ni, Cr (total), − BrO and trihalomethanes (total) were observed in the level of their quantification or less than it or concentration changes were observed only in some cases that are significantly less than their maximum permissible values (MPV). The processed data show that higher concentrations of sulphate in Jelgava and Jurmala drinking water were observed. In Jelgava drinking water sulphate concentration exceed the accepted MPV for 97 mg/dm3 and in Jurmala - for 26 mg/dm3. Besides, high values of total iron (1.15±0.54 mg/dm3) and turbidity (14.2±7.2 nephelometric turbidity units) were obtained also in Jelgava drinking water. Relative high concentration of aluminium in Liepaja drinking water (0.2 mg/dm3) takes place that achieves the MPV. Confidence intervals of mean values were calculated using Chebyshev's inequality. The processed data testify well even very well quality of the analyzed largest Latvia drinking water supply systems.
W 2008 r. wykonano statystyczną ocenę jakości wody pitnej pobranej z siedmiu największych systemów wodociągowych Łotwy (Ryga, Daugavpils, Liepaja, Ventspils, Jelgava, Jurmala i Rezekne) na podstawie ich składu chemicznego. We wszystkich analizowanych wodach pitnych stężenia Hg, Cd, Pb, Cu, Ni, Cr (stężenie całkowite), − BrO i trihalogenometanów (stężenie całkowite) były na granicy oznaczalności lub poniżej. Tylko w niektórych przypadkach obserwowano zmiany stężeń, ale były one znacznie mniejsze od dopuszczalnej wartości maksymalnej (MPV). Na podstawie analizy danych stwierdzono zwiększone stężenie siarczanów w wodzie pitnej z Jelgavy i Jurmaly. W wodzie pitnej Jelgavy stężenie siarczanów przekraczało maksymalne wartości dopuszczalne (MPV) o 97 mg/dm3, a w Jurmale - 26 mg/dm3. W wodzie pitnej z Jelgavy stwierdzono też duże całkowite stężenie żelaza (1,15 ± 0,54 mg/dm3) i znaczne zmętnienie (14,2 ± 7,2 NTU). Stwierdzono stosunkowo duże stężenie glinu w wodzie pitnej z rzeki Liepaja (0,2 mg/dm3), sięgające MPV. Przedziały ufności wartości średniej zostały obliczone z wykorzystaniem nierówności Czebyszewa. Analizowane dane świadczą o bardzo dobrej jakości wody pitnej z badanych sieci wodociągowych Łotwy.

Opis:
Water in the nature is not distributed in sufficient quality and quantity in time and space to meet water demands in line with the requirements for safe drinking water. In the past, water was free for all and one could use it without any restrictions for his needs. Drinking water consumption increases due to the impact of demographic trends and the level of water supply as well as technological and industrial development. Meeting the demands is more difficult because of limited possibilities of increasing food production due to pollution and increasing demands for use of natural resources.
Woda w przyrodzie nie jest rozprowadzania w odpowiedniej jakości i ilości w czasie i przestrzeni, aby sprostać wymogom bezpieczeństwa wobec niej. W przeszłości woda była darmowa dla wszystkich i każdy mógł używać jej bez jakichkolwiek ograniczeń. Konsumpcja wody pitnej wzrosła ze względu na wpływ tendencji demograficznych oraz poziomu jej zaopatrzenia jak również ze względu na rozwój przemysłu. Sprostanie wymaganiom jest trudniejsze, ponieważ ograniczone są możliwości zwiększenia produkcji jedzenia przez zanieczyszczenia oraz zwiększenia wymagań wobec użycia źródeł naturalnych.

Opis:
The present study aimed to assess groundwater quality according to the water quality index (WQI) in Ali Al- Gharbi district of the Maysan Governorate in eastern Iraq. For this purpose, 10 physical parameters such as pH, total hardness (TH), magnesium (Mg2+), calcium (Ca2+), potassium (K+), sodium (Na+), sulphate (SO42–), chloride (Cl–), nitrate (NO3–), and total dissolved solids (TDSs) were examined since 2019 from 16 different locations (viz. wells). The analysis results indicated that 18.75% of the water samples were of good quality, 56.25% of them had low quality, and 25% of such samples were very poor. The WQI also varied from 69.67 and 297.6. Therefore, prior to water use, there is a dire need for some treatments, as protecting this district from pollution is significant.

Opis:
Groundwater is a key source of drinking water in Jordan. This study was conducted to assess the suitability of groundwater in major groundwater basins in Jordan for drinking purposes. The groundwater quality data from sixteen sampling stations within one-year-monitoring period from March 2015 to February 2016 were used. Weighted arithmetic water quality index (WQI) with respect to the Jordanian standards for drinking water was used for quality assessment. Sixteen Physical, chemical and microbiological parameters were selected to calculate WQI. The result showed that all physical and chemical parameters were almost below the maximum allowable level based on the Jordanian standards for drinking. On the other hand, the microbiological parameter (i.e. E.coli count) was exceeded the maximum allowable limit in all the studied locations based on the Jordanian standards for drinking water. The computed WQI values range from 40 to 4295. Therefore, out of 16 studied locations, three locations are classified in the “Excellent water” class, nine locations as a “Good water” class, one as a “Poor water” class, two as a “very poor water” class, and one as a “water unsuitable for drinking purpose” class. Furthermore, Escherichia coli is considered the most effective parameter on the determination of WQI in this study. This result highlighted the importance of including the microbiological parameters in any drinking water assessment, since they reflect with other physical and chemical parameters the actual condition of water quality for different purposes.

Twenty groundwater samples were collected and then examined for physical (pH, EC, TDS) and chemical (Na+, K+, Ca2+, Mg2+, HCO3−, Cl−, SO42−, NO3) parameters, followed by multivariate statistics to determine the current state of groundwater quality and to assess the suitability of these resources for drinking and irrigation purposes in the Baser Sakhra area localized in Eastern of Algeria. The analysis carried out showed that the cations trend in most of the groundwater samples is on the order of Ca2+˃Na+˃Mg2+˃K+ and the anions trend is on the order of HCO3-˃SO42-˃Cl-. Stabler diagram demonstrated the predominance of Ca2+- HCO3- hydro-chemical facies (80%). Moreover, the parameters, such as sodium adsorption ratio, percentage sodium, residual sodium carbonate, permeability index, Kelly’s ratio, potential salinity, and magnesium hazard were evaluated for the suitability of groundwater for irrigation. The values obtained in this investigation concluded that most of the groundwater samples are suitable for irrigation. From the other approach, the Water Quality Index (WQI) for drinking was also used in the current study. WQI ranged from 72.46 to 506.426, indicating that 40% of the samples were suitable for drinking however, 60% of them belong to the poor to unsuitable category of drinking water in terms of physicochemical properties, according to the World Health Organization norms.

Opis:
Water is one of the most important natural resources for all living organisms, including humans. Water consumption is increasing over the years as a result of the increase in the number of people, and at the same time, the causes of pollution of surface water sources increase. Water pollution is one of the most important causes of diseases and the transmission of infection to the organisms that use it. Also, the quality of agricultural crops is linked to the quality of the water used for irrigation. As a result, there was a need to monitor and evaluate the main water sources to maintain the quality of their water suitable for use by humans and other organisms. As is well known, it is difficult to evaluate the water quality of large samples with concentrations of many parameters using traditional methods, which depend on comparing experimentally determined parameter values with current standards. As a result, over the past century and the present, many methods of assessing water quality have emerged. This research aims to introduce the most important indices of water quality used at present to assess the quality of surface water for drinking and irrigation purposes, as well as the history of these methods and their development over time and their most important advantages, in addition to a group of the most important research that used these methods during the past few years.

Opis:
In recent years, the natural and economic situation in the Republic of Crimea has developed in such a way that the amount of available water resources is less than the amount of water necessary for the socio-economic development of the peninsula. This article considers one of the main water management hazards for the territory of Crimea: a lack of water. The aim of this study was to assess the water deficit and determine ways to minimize the impact of risk exposures on the population, the economy and the ecosystem as a whole. Options are provided to ensure that (1) the water economic complex supplies water to consumers in sufficient quantity and quality, and (2) the ecological status of water bodies is maintained at a high level. For example, local wastewater treatment and desalination of sea water can be used in agro-industry and the water economic complex both for individual agricultural producers and for large enterprises. The economic efficiency of the use of technologies to reduce the environmental threats of the water economic complex was assessed using technologies to increase water availability. The analysis of the quality of water resources is given, and options for improving the indicators of raw water-pipe water are proposed.

Opis:
The paper covers the analysis of water management problems in the cross-border reservoir basin of Bukówka, located at the Bóbr river, at 271+540 km of its course, below the Czech-Polish border, in Dolnośląskie Voivodeship. The problems of water management in the context of the reservoir’s functions have been analyzed; these are: flood control, the provision of water during low water level periods for the Water Treatment Plant in Marciszów, the provision of drinking water for the city of Wałbrzych as well as the provision of proper flow in the Bóbr river bed downstream from the reservoir. Due to its localization right below the border with the Czech Republic, the reservoir is exposed to a number of problems. The study has found that the main problems of water management in the basin area included unsatisfactory state of water and wastewater management in the basin, unsatisfactory state of the surface water quality in the basin area of the reservoir, poor condition of streams and drainage ditches, improper arrangement of arable lands and large downslopes and a lack of monitoring stations on tributaries of the reservoir. It has been found that the hydrochemical conditions in the Bukówka reservoir’s section are unfavorable for it. From the eutrophication point of view, the water flowing into the tank is characterized by a large content of nutrients, especially nitrates, phosphates and BOD5. In order to counteract eutrophication it is necessary to lower the concentration of nutrients in the water flowing into the tank. One of the basic ways to do so is to restore the water and wastewater management in the reservoir’s basin. Studies in the Bukówka reservoir provide important information concerning the state of the purity of the water supplying the reservoir. In order to obtain accurate information on the state of purity, a monitoring of hydrological and water quality should be continued. The studies are a part of the strategy of protection of the quality of transboundary waters, proposed in the Convention on the Protection and Use of Transboundary Watercourses and International Lakes of 1992.

Opis:
Samples of drinking water collected in Warka-Grójec region of central Poland were tested for the presence of pesticides. Data obtained from analysis of water samples will be used for future epidemiological and environmental studies in the region. Samples were collected during spring and autumn of 2002-2003 from dug wells, deep wells and water mains in 81 randomly-selected rural households scattered throughout this region of extensive agriculture. The concentration of pesticides from four main chemical groups was determined by gas chromatography: organochlorines (lindane, DDT, methoxychlor), triazines (atrazine, simazine), organophosphates (acephate, diazinon, fenitrothion) and pyrethroids (alpha-cypermethrin, deltamethrin). Two-year monitoring of drinking water samples indicated the presence of DDT and methoxychlor contamination. Pyrethroids were generally not detected, with the exception of alpha-cypermethrin found in only a few samples. Triazines were also found in water samples collected in the course of the study with higher incidence during spring period. Organophosphates were by far the most common contaminants of drinking water in this region. Almost all samples were contaminated by signifi cant amounts of fenitrothion. The present study reveals an urgent need for systematic monitoring of drinking water quality in regions of intensive agriculture, since they are highly vulnerable to pesticide contamination. Consumption of pesticide-contaminated water may have a negative impact on the population living in this area, which also requires scientifi c assessment.
