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:: 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:: 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.

Opis:: In this article, the purpose of the research was to study the ecological characteristics of groundwater and central water supply used for drinking and economic activity of the Kievka village. The hydrochemical indicators of the samples were determined with conventional methods, and performed on 16 indicators: pH, electrical conductivity, suspended solids, dry residue, chlorides, sulfates, phosphates, total hardness, sodium, ammonium nitrogen, nitrites, nitrates, chemical oxygen consumption (COD), anionic surfactants (APAS), total iron, and manganese. While assessing the hydrochemical state of drinking water in the village of Kievka, it can be noted the "Altyn-dan" kindergarten and the Kiev secondary school No. 3, exceed the MAC which is determined by certain indicators. As a result of microbiological studies of the water samples from the village of Kievka, it was revealed that the total microbial number is normal. It was determined that a different number of fungi and actinomycites were present in all samples. At the initial concentration, a large concentration of fungi was observed in all samples.

Opis:: 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:: 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:: The aim of the study was to assess the qualitative status of groundwater and surface water abstracted for the needs of customers in the city of Nowy Targ. The assessment was based on the results of physicochemical analyses of 62 water samples taken from the water intake on the Biały Dunajec stream in Szaflary (emergency water intake) and 280 samples taken from 6 active groundwater intakes in Nowy Targ. The basic descriptive statistics of manganese, iron, magnesium, calcium, chlorides, sulphates, phosphates, phosphates, ammonia, nitrites, nitrites, nitrates, chromium, zinc, indicators such as: dissolved oxygen, BOD5, suspension, phenols, PUR, pH, total hardness, alkalinity and number of coli bacteria were determined. The water analyses were performed in the period 2004-2016. Basic descriptive statistics of manganese, iron, magnesium, magnesium, calcium, chlorides, sulphates, phosphates, ammonia, nitrites, nitrates, chromium and zinc ions, as well as such indicators as: dissolved oxygen, BOD5, suspension, phenols, PEW, pH, total hardness, alkalinity and number of coli bacteria were determined. The quality of the captured waters was classified on the basis of the results obtained, noting that the water from the Biały Dunajec stream corresponds to the A3 purity category due to the microbiological contamination. According to the physicochemical standard, A3 category was also determined on the basis of the phenol concentration, which, however, decreased significantly since 2013, corresponding to category A1. For groundwater, on the other hand, it was established that all analysed indicators corresponded to class I purity grade, i.e. water of a very good quality. The only excess over the values corresponding to this class was recorded for calcium ions, but the classification of water quality has not changed due to the fact that it was caused by natural processes. Taking into account the above-mentioned findings, it was concluded that due to the very good groundwater quality, their intakes should be left as the main source of water for consumers in Nowy Targ, while the surface water intake on the Biały Dunajec stream should be maintained concurrently as an emergency intake.

Opis:: The current study was undertaken to assess the physicochemical quality of the Kufranja dam (KD) surface water in northern Jordan during the summer and winter seasons [2019]. The samples were analyzed for temperature, pH, dissolved oxygen, conductivity, major cations, major anions, and heavy metals. Most of the physicochemical parameters exhibited a similar spatial distribution, where the maximum concentrations were observed at the dam’s entrance, while the minimum concentrations were recorded at the dam’s end. This indicates that the factors affecting their occurrence and distribution are the same, including natural discharges from the surrounding catchment areas, weathering products, agricultural activities, and wastewater effluents that enter the dam via Wadi Kufranja. All the physicochemical parameters and heavy metals in KD water lie below the maximum permissible levels of the Jordanian and international standards for drinking and irrigation, except for EC values that are above WHO standards for drinking. The application of the water quality index (WQI) depicts that the KD water is chemically unsuitable for use in drinking and needs proper treatment before use. The irrigation indices (SAR, Na%, and MH) indicate that the KD water is chemically suitable for irrigation, whereas EC results and USSL diagram showed that the dam’s water is suitable for irrigation and belongs to the categories of good to permissible for irrigation. Therefore, KD water is suitable for irrigation of most soils (except soils with low salt tolerance). Crops with good salt tolerance are recommended and a special treatment of salinity might be required.

Opis:: The Taanzoult plain of Aguelmam Sidi Ali wetland contains several permanent springs of water. They are intended for watering livestock, supplying drinking water and hydrotherapy. Nevertheless, the water consumption from sources in the raw state, without any pre-treatment or hygienic measures, certainly threatens the health of humans and particularly that of traditional medicine patients. From this perspective, the present work is based on a monthly monitoring of eight bacterial germs in the waters of four sources (Aghbalou Aberchane, Aghbalou Dkhiss, Aghbalou Akjdate and forestry post) during a hydrobiological cycle of 12 months from January to December 2017. The results of analyses have shown that bacterial contamination is significant at the water sources, used mainly for watering livestock, compared to those dedicated to drinking and hydrotherapy. The mean content of total coliforms and fecal coliforms at all the stations are higher than the Moroccan standards for surface water intended for the drinking water production. Except for the wet period for Aghbalou Aberchane and Aghbalou Dkhiss waters, the value of the bacterial parameters studied are higher than the Moroccan standards. In general, the anarchic frequentation of the area negatively influences the water quality and compromises its potability. Consequently, it directly threatens the health of users and hydrotherapy patients, especially during the dry season. These findings could call on the health authorities and the competent authorities responsible for controlling the quality of surface water to make users aware of the health risks and provide for appropriate arrangements to improve the quality of the widely sought-after natural waters.
