Opis:: This study includes two parts; the first one, concerns evaluation of the physicochemical and microbiological quality of the urban wastewater of the city of Fez, through a space-time dynamics. In turn, the second part deals with the contribution to the treatment of these effluents, by a new biodegradable reagent in the process of physicochemical treatment (coagulation flocculation). For this purpose, the sampling of urban wastewater was carried out 4 months (September, December, February and June 2019), at a rate of two samplings per period on 4 specific sites along the river Fez, the degree of contamination of which differs from one site to another, according to space and time. The diagnostic of these stations showed a high level of pollution that is difficult to biodegrade. Indeed, this pollution can cause negative effects not only on the environment but also on human’s health. In order to take long-term action against the low quality of water and to replace certain inorganic coagulants, alternative processes for water treatment using cactus powder were set up. The characterization of results showed that the urban effluent has a high load in terms of electrical conductivity (EC), dissolved oxygen, chemical oxygen demand (COD), as well as concentrations of faecal coliforms, streptococci and staphylococci. In addition, the purifying power revealed that the removal rate of COD reaches maximum values of 38% and 58% forlimeand the mixture of lime with cactus powder, respectively.

Opis:: The composition of the sediments formed in the process of stormwater pretreatment is diversified and depends on many parameters, mainly on the quality of stormwater and the land use of the catchment. The stormwater sediments are characterized by heterogeneous chemical and microbiological composition. The aim of this paper was the microbiological evaluation of the sediments from four stormwater catchments in terms of hazard to humans and the environment. The pH, and the content of organic and mineral matter were determined for the examined sediments. The microbiological analysis included the determination of the total number of psychrophilic, mesophilic, and coliform bacteria, including E. coli, and also the number of faecal Enterococci, Salmonella and Shigella. The study was conducted for fresh deposits and those stored for one year in order to determine the dynamics of changes in their biological activity.

Opis:: The purpose of the three-year-long field experiment was to identify the effect of the UGmax soil fertilizer (microbiological preparation) on the presence of Streptomyces scabies on tubers of two edible potato cultivars. The experiment was established using the randomized split-block method, in three replications, in central Poland (52°03’N; 22°3’E), on the soil consisting of loamy sands, slightly acidic and acidic. The examined factors included: 1st factor: edible potato cultivars (Satina and Typhoon), 2nd factor: doses and dates of application of the U_Gmax soil fertilizer (1. control object without U_Gmax; 2. U_Gmax applied to soil before planting tubers at a dose of 1.0 dm³∙ha^-1; 3. U_Gmax applied to soil before planting tubers at a dose of 0.5 dm³∙ha^-1, when the height of plants is about 10–15 cm, and in the flower buds making phase at a dose of 0.25 dm³∙ha^-1; 4. U_Gmax before planting tubers at a dose of 1.0 dm³∙ha^-1 and when the height of plants is about 10–15 cm, and in the flower buds making phase at a dose of 0.5 dm³∙ha^-1; 5. U_Gmax when the height of plants is about 10–15 cm, and in the flower buds making phase at a dose of 0.5 dm³∙ha^-1). Symptoms of common scab were assessed on a 9-point scale on 100 tubers randomly collected from different experiment objects. As a result of the study, it was demonstrated that treatments with the use of the U_Gmax soil fertilizer limited the occurrence of common scab on potato tubers and affected the average level of infestation of the sample and the average level of infestation of infested tubers.

Opis:: The condition of air quality depends on many external (the amount of pollutant emissions, intensity and type of physico-chemical changes taking place in the atmosphere and large-scale movement of air pollutant masses) as well as internal factors (such as finishing materials, room equipment, heating systems, ventilation systems, and the presence of the humans themselves). As a result, there are various risks related to air quality, including the most important ones related to microbial contamination. For this reason, it was decided to analyze the quality of internal air in terms of microbiological contamination that may occur in university lecture halls with mechanical supply and exhaust ventilation. The analysis also took into account the impact of mechanical ventilation on physical parameters such as temperature, relative humidity as well as the concentration of PM10 and PM2.5 particulate matter pollutants, thus determining the impact of the tested parameters on human health and well-being. All the obtained results were compared with the applicable permissible standards and conclusions were drawn regarding the improvement of the quality of the indoor air microclimate.

Opis:: The purpose of this study was to determine the quality of water in lake Batllava, through which, a part of the population of the Pristina region is supplied with drinkable water. Lake Batlava is a lake built in the 1970s. This lake is located in the village of Batlava in the municipality of Podujeva. The supply of this lake with water is made from the Brvenica river. Monitoring was finished during the period from December 2020 to May 2021. The sample were taken in three championic places: at the entrance of the lake, in the middle and in the spill, on two levels, in the surface and at depth of 30 cm. The analyzed microbiological parameters are: total coliforms, fecal coliforms, fecal streptococci and aerobic mesophilic bacteria. The physical-chemical parameters are: dissolved oxygen, saturation with O2, water temperature, pH value, electrical conductivity, total soluble matter, total suspended matter, turbidity, chemical demand for oxygen, biochemical demand for oxygen, total organic carbon, nitrate, total solidity of calcium, magnesium, ammonia ion, chloride, sulphates, fluurite, M-alkalines, bicarbonates and heavy metals, such as: Fe, Pb, Mn, Cu, Cd. The results showed that most physical-chemical and microbiological parameters are within the limit allowed by the WHO and EPA, except in some cases where during the precipitation season there have been several overruns and for this reason, it is recommended to take monthly monitoring of the water of Lake Batllava to achieve a real assessment.

Opis:: This research was intended to analyze the water quality of the Cikapundung River in Bandung City around the densely-inhabited slums and also to analyze the total number of bacteria coliform and Escherichia coli in the Cikapundung River, Bandung City. The research data was obtained by observing and performing a laboratory analysis through the assessment of environmental quality standard threshold based on the Government Regulation (PP) No. 82 of 2001. The results of laboratory analysis show that the actual condition of water quality of the Cikapundung River is overall classified as polluted, indicating 7 microbiological and physico-chemical parameters which have exceeded the quality standard such as: TSS, DO, BOD, COD, detergent/surfactant, total coliform, and Escherichia coli. In the upper part, there are 6 parameters below the quality standard, consisting of 4 physicochemical parameters and 2 microbiological parameters. In the middle part, there are 8 parameters below the quality standard consisting of 6 physico-chemical parameters and 2 microbiological parameters. In the lower part, there are 6 parameters that exceeded the quality standard consisting of 4 physico-chemical parameters and 2 microbiological parameters. The seasonal difference of parameters averagely has shown that the water quality in the rainy season is better than in the dry season. However, on average, the water sampling taken before flowing to the village has a better quality than past the village.

Opis:: This study presents an assessment of the protection provided by water intake and treatment systems against potential health risk to water consumers. To perform the assessment a case study was conducted involving modelling and risk assessment based on scenarios of decreasing water quality at the intakes (i.e. emergency situations). The study sites were two continuously operating water treatment plants in Southern Poland (CEE). The study material were the results of tests conducted in the years 2012–2019 on samples of water taken directly at the intakes and samples of treated water. The samples were used to determine the concentration of selected metals (Cd, Cr, Mn, Ni, Pb and Zn), organic pollutants (benzo(a)pyrene, benzene, acrylamide, epichlorohydrin, vinyl chloride and 1,2-dichloroethane) and bacteriological pollutants (Coliform bacteria, Escherichia coli, Enterococcus faecali and Clostridium perfringens). The non-carcinogenic (HI) and carcinogenic (CR) hazard indexes were estimated based on the quality of water at the intake using linear regression models. The risk values obtained were compared with permissible values specified in the US EPA methodology. It was demonstrated that the concentrations of the xenobiotics analysed in treated water would have to increase 11 times in the case of adults and 29 times in the case of children before the risk level related to drinking water exceeded permissible values. In the least favourable exposure scenario modelled, assuming the presence of organic xenobiotics in potable water, the total HI amounts to only 10% of the permissible value in adults and 1.5% in children. The total CR calculated for the 3-times lower water quality did not exceed permissible values, which proves that the water treatment systems are safe.

Jayapura Regency
Opis:: In Indonesia, the river water quality has been determined based on Government Regulation of the Republic of Indonesia No. 22 of 2021. This study aimed to determine the quality of surface water from the Damsari, Jabawi, Kleblow, and Komba Rivers in Jayapura Regency based on the monitoring data from 2016 to 2019. The CCME-WQI method is used to determine the status of rivers based on river water quality standards (class 1 to class 4). The results of the study showed that the parameters of water temperature, TDS, pH, $NH_3, NO_3^-, SO_4^-2$, surfactant, oil/grease, Cr-(IV), Mn, Fe, Fecal Coliform, and Total Coliform were still in accordance with the quality standard. Meanwhile, TSS, COD, BOD, Total Phosphate, Hg, and Ni have exceeded the water quality standard, where the dominant pollutant source is an anthropogenic waste. On the basis of the WQI average value, the four rivers are not suitable as a source of drinking water (Poor-Marginal; 41.33 – 58.25). The Jabawi River can be used as a recreational facility, but it must be under special management (Fair; 69.75), while the other three rivers are not suitable (Marginal; 52.00 – 61.67). The Jabawi and Komba Rivers are in the Fair category (75.50 and 69.33) to support aquatic life, while the Damsari and Kleblow Rivers are in the Marginal category (59.00 and 61.25). The water quality of the four rivers is very good and suitable to be used as a water source for irrigation (Good category; 80.00 – 88.00). The strategies for controlling river water pollution and increasing the role of the government, stakeholders, and the community are needed.

Opis:: The study of the composting process is a very urgent task. The rapid growth in food production leads to the formation of waste, which should be safely disposed of in a natural way – composting. Composting the vegetable component of food waste can significantly reduce the proportion of waste falling into landfills and utilize the food waste from the hotel and restaurant industry. Additional enrichment of the compost mixture of food waste with the «Baikal EM» microbiological additive accelerates the maturation process and enhances the efficiency of the finished compost. Such compost does not contain viable weed seeds or pathogenic microflora and can be used as a fertilizer. In contrast to the control, a sufficient level of germination index is observed for the studied samples and they are not phytotoxic. The finished compost can be used as a fertilizer in agriculture for growing crops. The results obtained indicate that the index of germination of radish seeds increases along with the duration of fermentation of the composted mixture. Communities of microorganisms contained in the «Baikal EM» additive accelerate the natural process of composting, taking an active part in the destruction of the components of the vegetable mixture. The pH value of the finished compost, both under thermophilic and mesophilic conditions, is close to neutral indicators. High values of CO2 emissions from reactors were recorded in the second week under thermophilic and for 3 weeks under mesophilic conditions. The finished compost that fermented under thermophilic and mesophilic conditions can be used as fertilizer, but considering that additional energy is required to create thermophilic conditions, it is advisable to compost the food waste mixture with the addition of the microbiological additive «Baikal EM» under mesophilic conditions.

Opis:: One of the greatest environmental problems of modern countries is the pollution of territories with waste. Of particular concern are the wastes generated during the treatment of municipal wastewater, i.e. sewage sludge. They are the inevitable price of urbanization and improved quality of life. As a result of the research conducted, a comprehensive analysis of the composition of municipal sewage sludge was conducted using the example of four small settlements in East Kazakhstan. The results of laboratory studies established the composition of the organic part, biogenic elements, as well as microbiological and parasitological indicators. It was revealed that cadmium, copper, zinc and arsenic are main sources of problems in wastewater treatment plant sludge. For copper and zinc, the standards set by the European Directive 86/278/EEC were exceeded by up to 3.2 and 1.5 times, respectively. At the same time, there is an increased content of nutrients. Organic matter in all studied samples exceeds the minimum established values by 3.5–3.7 times; the potassium content in all studied samples is 5.1–5.6 times higher than the minimum established value for organomineral fertilizers in the Republic of Kazakhstan. The concentration of hydrogen ions (pH) corresponds to neutral. Tests for the determination of microbiological and parasitological parameters indicate that the studied sludge does not contain various pathogenic bacteria and microorganisms.

Opis:: W Polsce ogromnym problemem jest zanieczyszczenie środowiska gruntowo-wodnego przez nieczystości płynne, pochodzące ze zbiorników bezodpływowych. Dotyczy to szczególnie terenów wiejskich. Negatywne zmiany stwierdzane są zarówno w sąsiedztwie nieszczelnych zbiorników, z których zagęszczone i zagniłe ścieki infiltrują do gruntu, jak i w wodach powierzchniowych i gruntach ornych, do których trafiają nieczystości z opróżnianych zbiorników. W pracy, na przykładzie wybranej gminy, przedstawiono skalę występowania procederu niekontrolowanego odprowadzania ścieków bytowych do środowiska. Zaprezentowane dane porównano z wynikami oceny jakościowej wód podziemnych, ujmowanych w tej samej gminie do celów wodociągowych. W znaczącej części studni woda nie była bezpieczna pod względem sanitarnym, bowiem stwierdzono w niej obecność m.in. zanieczyszczeń mikrobiologicznych. Wśród oznaczonych mikroorganizmów dominowały organizmy wskaźnikowe zanieczyszczenia wód ściekami bytowymi. Problemy z jakością wody zostały odnotowane na ujęciach, zlokalizowanych w pobliżu posesji, wyposażonych w zbiorniki bezodpływowe lub w miejscach, do których w niekontrolowany sposób trafiały ścieki z opróżnianych zbiorników. W ten sposób wykazano, że istnieje związek między niewłaściwie prowadzoną gospodarką ściekową a jakością wód podziemnych, ujmowanych do celów wodociągowych.
Pollution of soil and water environment by liquid waste originating from septic tanks is a huge problem in Poland. This applies especially to rural areas. Negative changes are observed both in the vicinity of the leaking tanks, from which concentrated and rotten sewage infiltrates into the ground, and in surface water as well as arable land, to which impurities from the emptied tanks are discharged. The paper presents the scale of the practice of uncontrolled domestic sewage discharge into the environment on the example of selected municipality. Presented data were compared with the results of the qualitative assessment of groundwater, which is collected in the same municipality for waterworks. In a significant number of wells, water was not safe in sanitary terms, as the presence of microbiological contamination was recorded. Among determined microorganisms, the indicator organisms of domestic waste pollution prevailed. Water quality problems have been reported at intake points located near the properties equipped with septic tanks or in places, to which sewage from emptying septic tanks were transferred in an uncontrolled manner. In this way it has been shown that there is a relationship between improperly maintained wastewater management and groundwater quality collected for the purpose of water supply.

Opis:: The work presented the assessment of household wastewater treatment plants with drainage systems on the quality of groundwater in dug wells and deep water wells in the area of 3 selected communes (Drelów, Dębowa Kłoda and Urszulin), located in the Lublin province in south-eastern Poland. The investigations of the physicochemical composition of water from selected 28 dug wells and 2 deep water wells were conducted from June to July 2020, involving 9 measurement series. The microbiological studies consisted in 4 measurement series. The composition of the wastewater from primary settling tanks discharged to soil via drainage systems located in the vicinity of considered wells was also examined on a single occasion. The studies indicate that the water from wells are significantly polluted with ammonia, nitrites, as well as compounds of natural origin: iron and manganese. The presence of microbiological pollution of fecal origin was noted. The studies clearly indicate the possible pollution of the analyzed well waters with domestic sewage discharged to soil via drainage systems. Therefore, it necessary to take the actions aimed at improving the quality of groundwater in the Lublin province, including limitation of drainage systems, especially in the areas with unfavorable subsurface and hydrological conditions as well as low water supply coverage. The need to introduce changes in legal regulations and strategies for the development of technical infrastructure in counties, favoring the most efficient, as well as simple and inexpensive technologies, was indicated.
