Opis:: The purpose of the study is to evaluate the efficiency of removing organic pollutants from wastewater in a household wastewater treatment plant with a hybrid reactor. The efficiency of the plant was analyzed in terms of decreasing BOD₅, COD and the content of total suspended solids in differentiated technological conditions. The variable parameter was the length of the reactor aeration phase and the dwell phase. Six different aeration variants were analyzed. The efficiency of a wastewater treatment plant with a hybrid reactor in terms of reducing BOD₅ oscillated from 81 to 90%, COD – 64–84%, whereas total suspended solids – 66–89% which, as a rule, was not sufficient to achieve standard levels. The best results were achieved for the following variants: 2h aeration – 2h dwell and 1h aeration – 0.5h dwell. Lower efficiency of the plant could have been attributed to operational problems, mainly failures of the plant control system and uneven conditions such as air temperature, volume and composition of wastewater received in the plant.

Opis:: The aim of this paper is to present the current state and the need for development of sanitary infrastructure in the communes of Parczew District, in Lublin Voivodeship. Parczew District encompasses seven communes: Parczew, Dębowa Kłoda, Jabłoń, Milanów, Podedwórze, Siemień, and Sosnowica. The present paper uses the data from the surveys conducted in these communes in 2016. On average, 88% of the population used the water supply system in the communes surveyed, while 48% of the inhabitants were connected to a sewerage system. Parczew District had 12 collective mechanical and biological wastewater treatment plants with a capacity exceeding 5 m³/d. The households which were not connected to the sewerage network discharged the wastewater mainly to non-return tanks. In the communes surveyed, 1,115 households had domestic wastewater treatment plants. All of them were systems with infiltration drainage, which do not ensure high efficiency of removing pollutions and may even contribute to the degradation of the groundwater quality. In order to solve the existing problems of sewage and water management in the communes of Parczew District, it is necessary to further develop the collective sewerage systems and equip the areas which have a dispersed development layout with highly efficient domestic treatment plants, such as constructed wetlands.

Opis:: This paper reports the results of tillage experiments that were set up to investigate the intensity of net soil displacement and the associated tillage erosivity for mouldboard tillage carried out in direction parallel to the contour lines (contour tillage). Tillage was performed with typical set of cultivation for an average farm on soil developed from loess located on a slope with 7.5 to 13.5% decrease. Aluminium cubes of 15 cm edge-length were used as tracers. The studies showed that average translocation of soil along the slope (perpendicular to tillage direction) was 0,35 m and 0,28 m respectively for tillage with downslope and upslope direction of soil overturning. It means that each year about 2,89 Mg per hectare of soil is net displaced in downslope direction per plough operation. The studies indicated that contour moldboard tillage is also an important factor in relief and soil transformation of eroded areas.

Opis:: The quality of surface water in watercourses in the region of Lublin agglomeration was studied in 2012–2014. Biological and chemical indicators of the study for various sampling sites were detected and the resulting values of the indicators were processed statistically. Rivers characterized by small size and the flow and modification of the riverbed. The resulting low values of macrophyte river index and infusorial index pointed to a poor quality of surface waters. Chemical indicators of the quality of surface waters reached low values, only BOD and phosphates reached high values. The river is located outside the city and it is characterized by moderate potential ecological (III quality class), and the river within Lublin is insufficiently potential ecological (IV quality class). Statistical analysis showed high variability index values between the studied positions.

Opis:: The paper presents the results of research on the effects of removing pollution from domestic wastewater in two beds of constructed wetland systems with vertical flow. Bed I was planted with common reed (Phragmites australis Cav. Trin. Ex Steud.), whereas bed II with Glyceria maxima (Glyceria aquatica L.). The surface of each of the beds amounted to 30 m², and the hydraulic load of each of them amounted to 0.033 m³·m^-2·d^-1. The study showed very good results in the removal of most of the analyzed indicators of contamination, which were similar in both analyzed beds. They were, respectively: 91 and 93% – for total suspended solids, 96 and 98% – for BOD₅, 96 and 94% – for COD_Cr, 88 and 86% – for ammonia nitrogen and 87 and 88% – for total phosphorus. Much smaller effects were reported with regard to total nitrogen removal – 55% in bed I with common reed and 54% in bed II with Glyceria maxima. The tested beds also eliminated the number of coliform bacteria and faecal coliform bacteria quite effectively. Average effects of the removal of coliform bacteria in bed I and II were 99.74%, in the case of faecal coliform 98.06% and 97.94% respectively. Values of basic indicators of contamination (total suspended solids, BOD₅ and COD_Cr) in the wastewater discharged from the analyzed beds met the requirements of the Regulation of the Minister of the Environment of 2014. The test results obtained in the first year of operation of the analyzed beds show that neither of the applied plants significantly improves the results of contaminant removal.

Opis:: W pracy przedstawiono ocenę wpływu przydomowych oczyszczalni ścieków z drenażem rozsączającym na jakość wód podziemnych w studniach kopanych i głębinowych w miejscowości Kwasówka w gminie Drelów (woj. lubelskie). Na badanym obszarze nie ma sieci kanalizacyjnej i wodociągowej, a ludność miejscowa korzysta ze studni kopanych lub głębinowych. Ścieki powstające w gospodarstwach domowych trafiają do zbiorników bezodpływowych lub przydomowych oczyszczalni ścieków z drenażem rozsączającym. Badania jakości wód podziemnych ze studni wykonywano w 2013 r. W ramach badań wykonano 4 serie analiz, podczas których określano: twardość ogólną, pH oraz przewodność elektrolityczną, jak również zawartość NO₃, NO₂, NH₄, Cl, SO₄, Fe, Mn oraz bakterii z grupy coli i coli typu kałowego, bakterii mezofilnych i psychrofilnych. Z badań wynika, że wody ze studni głębinowych są w znacznym stopniu zanieczyszczone żelazem, ponadto w kilku studniach kopanych odnotowano przekroczenie dopuszczalnych stężeń amoniaku, azotanów, manganu i siarczanów. Badania mikrobiologiczne wskazują na wyraźne zanieczyszczenie analizowanych wód studziennych ściekami bytowymi. Należy niezwłocznie podjąć działania mające na celu poprawę jakości wód użytkowanych przez mieszkańców miejscowości Kwasówka.
The paper presents an assessment of the impact of sewage treatment plants with drainage system on the quality of groundwater in dug and deep wells in the Kwasówka village in the municipality of Drelów (Lublin Province). In the study area there is no sewerage system and water supply, and the local population benefits from dug or deep wells. The wastewater generated by households goes to septic tanks or sewage treatment plants with drainage system. The study of groundwater quality from wells was performed in 2013. The study was performed 4 series of studies, during which determined: total hardness, pH and conductivity of the electrolyte, as well as the content of NO₃, NO₂, NH₄, Cl, SO₄, Fe, Mn and bacteria from coliform and faecal coliform bacteria, mesophilic and psychrophilic. The research shows that water from deep wells are heavily contaminated with iron, and several wells dug reported exceeding the permissible concentrations of ammonia, nitrate, manganese and sulfates. Microbiological studies indicate a significant contamination of the well water analyzed domestic waste. You should immediately take action to improve the quality of the water used by residents of Kwasówka.

Opis:: The aim of the work is to present the current state of water and wastewater management in the municipalities where the Polesie National Park (PNP) is located. The PNP is situated in Lublin Voivodeship, in the area of six municipalities: Sosnowica, Hańsk, Urszulin, Stary Brus, Wierzbica and Ludwin. The data used in this paper, were obtained on the basis of the surveys conducted in these municipalities in 2016 by the Department of Environmental Engineering and Geodesy of the University of Life Sciences in Lublin. In the analyzed communes, there was a very large disproportion between the usage of sewerage and the water supply network. It has been shown that 79.1% of the inhabitants living in the afore-mentioned communes used the water supply network and only 22.5% of them used sewerage. In the discussed communities there are 9 collective, mechanical and biological wastewater treatment plants with a capacity of over 5 m³•d^-1. On the farms located in the scattered areas, which are not connected to the sewerage, wastewater is discharged mainly to the septic tanks. In four out of the six analyzed municipalities, there were 2345 septic tanks registered. Domestic sewage from some farms is purified in household wastewater treatment plants (395 pieces). The plants with the drainage systems are prevalent (84.9%), which may contribute to the groundwater quality degradation. In order to protect the natural environment within the communes that form the PNP, it is necessary to undertake the actions that will contribute to the improvement of the current state of water and wastewater management. While solving the existing problems related to water supply and wastewater treatment, it is strongly required to adhere to the principle of sustainable development and use highly effective systems in order to ensure that the ecological effects are appropriate.

Opis:: Rational use of surface and underground waters leads to a reduction in their consumption, which is currently one of the fundamental tasks in the field of the conservation of waters, in its broad sense. This includes also the utilisation of water from additional sources, such as e.g. precipitation water. The paper presents an analysis of the quality of rainwater outflowing from the roofs of garage buildings of the Park Authority of the Roztocze National Park. The results of analyses presented in the paper indicate a favourable composition of rainwater that meets the norms defined for water for human consumption. In the waters under analysis, exceeded levels were noted for ammonia, manganese and biological factors, but these do not preclude the use of the waters for household purposes. Rainwaters at the Roztocze National Park can be used for car washing, for the irrigation of green areas, or for toilet flushing. Such utilisation of rainwaters can largely contribute to a reduction of the use of high-quality underground waters.

Opis:: The aim of this paper is to present the current state of water and sewage management in the communes where the Roztocze National Park (RNP) is located. The park is located in Lubelskie voivodship, in the territory of four communes: Zamość, Zwierzyniec, Adamów and Józefów, while its buffer zone is located in the communes of Krasnobród, Tereszpol and Szczebrzeszyn. The paper uses data from surveys conducted in these municipalities in 2016. On average, 68.9% of the population used the water supply system in the municipalities surveyed, while 33.4% of the inhabitants had the possibility of discharging sewage to the sewerage system. In the area of the communes, there are 10 collective, mechanical and biological wastewater treatment plants with a capacity exceeding 5 m³·d^-1. The households which are not connected to the sewage network discharge wastewater mainly to non-return tanks. Four out of the seven surveyed communities had 64 domestic sewage treatment plants, including 60 systems with infiltration drainage, which do not ensure high efficiency of removing pollution and may even contribute to the degradation of groundwater quality. In order to solve the existing problems in the area of sewage and water management occurring in the communes where the Roztocze National Park is located, it is necessary to further develop collective sewage systems and equip the areas with dispersed buildings with highly efficient, residential sewage treatment plants, e.g. constructed wetlands.

Opis:: The work evaluates the effect of anthropogenic pollutants on the quality of water in Lake Bialskie (51º32’07” N 23º00’55” E) and its catchment basin. Samples of water were taken from the lake (4 sampling points) and from wells dug within the catchment basin. The quality of water was analysed in May, June, August and November 2015. In the wells only in single cases was the level of chemical pollution found to exceed drinking water standards. However, in all samples the standard content of manganese was exceeded. In waters from the lake the concentrations of total phosphorus, which can contribute to eutrophication were recorded above the standard level. Both in waters from the lake and from the well a large count of meso- and psychrophiles and Coli and faecal coliforms as well as faecal Enterococci was found, which points to a high degree of contamination of the analysed waters with anthropogenic faeces. The phenomenon was observed to intensify in summer months, which can be associated with increased tourist traffic around the lake in this period.
