W publikacji dokonano charakterystyki metod usuwania związków fosforu ze ścieków komunalnych opracowanych w wybranych ośrodkach badawczych. W części analitycznej pracy opisano metody sorpcji fosforu z zastosowaniem skały węglanowo-krzemionkowej (opoki) i jej pochodnych oraz materiału Rockfos®. Materiał ten został poddany analizie w kilku laboratoriach oraz w kilku oczyszczalniach ścieków, jako złoże służące do eliminacji związków fosforu ze ścieków oczyszczonych odpływających z hybrydowych oczyszczalni hydrofitowych. Jak wynika z przeprowadzonej analizy materiał Rockfos® wykazuje się dużą skutecznością w zatrzymywaniu związków fosforu ze ścieków, przez co powinien znaleźć zastosowanie praktyczne w małych i przydomowych oczyszczalniach ścieków.

The publication characterizes the methods of removing phosphorus compounds from municipal wastewater developed in selected research centers. The analytical part of the paper describes the methods of phosphorus sorption using carbonate-silica rock (opoka) and its derivatives and the Rockfos® material. This material was analyzed in several laboratories and in several wastewater treatment plants as a bed used to eliminate phosphorus compounds from treated wastewater flowing from hybrid constructed wetlands. According to the analysis, the Rockfos® material is highly effective in retaining phosphorus compounds from wastewater, which should make it practical in small and household wastewater treatment plants.

The goal of the present study was to evaluate the efficiency of filters filled with Rockfos for removal of phosphorus (Total-P) from domestic wastewater using, Rockfos is a material obtained by calcination of carbonate-silica rock (opoka) at a temperature of 900 °C. A field study was conducted in two filters with volumes of 2.0 and 0.8 m3 which were components of hybrid constructed wetlands with an average capacity of 2.0 m3/L, located in two national parks in south eastern Poland. Samples of the influent to and the effluent from the filters were analyzed for Total-P concentrations and pH. Eighty sewage samples were tested over a five year study period. It was shown that the test filters removed Total-P with an average efficiency of 31.5% and 30.2% and that they could be successfully used to remove P from domestic wastewater in small wastewater treatment plants.

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.

The study aimed to assess the operation of the mechanical and biological wastewater treatment plant in Michów (Poland) in terms of the effectiveness of removing contaminants from mixed wastewater (dairy and domestic) and technological reliability. The wastewater treatment plant is owned by the Dairy Cooperative “Michowianka”. It is intended to treat mixed sewage, consisting of technological and sanitary sewage as well as part of rainwater from the plant, domestic wastewater supplied by a sewerage system from Michów, and wastewater delivered from septic tanks. In 2017 and in the first quarter of 2018, the permeate from the whey thickening process was also sent to the treatment plant. The period 2017-2021 was covered by the analysis. The analysis included the indicators from the fundamental group (TSS, BOD5, COD), biogenic indices (total phosphorus, total nitrogen, and ammonium nitrogen). The applied technology ensured the removal of total suspended solids, BOD5, and COD at the level of over 96%. Total phosphorus was removed with an average efficiency of 91%. Slightly lower effects were found in the elimination of total nitrogen – 78.5% on average, while the ammonium nitrogen removal rate was 88% on average. Due to the high efficiency of the facility, the values of the standard contamination indicators at the outflow, as a rule, met the requirements specified in the water permit. The technological reliability of the wastewater treatment plant in Michów, determined by the Weibull method, was at a high level, usually exceeding 90%. The reliability analysis shows that the facility in Michów has a high capacity to treat wastewater to the extent required for the wastewater receiver, and that the treated wastewater discharge does not cause negative changes in the environment. It indicates a high probability of obtaining the wastewater quality at the outflow from the treatment plant meeting the water permit requirements.

The aim of this paper was to evaluate the influence of anthropogenic pollution on the water quality of the Ciemięga River, which flows through the Jastków commune, located in the Lublin Province in the South-Eastern Poland. The analyses of the river water were conducted in the years 2019–2020. Each year, the samples for physicochemical analyses were collected seasonally (in February, May, August and November) from the seven selected Ciemięga River sampling points found in the following localities: Ożarów, Moszenki, Sieprawice, Jastków, Snopków and Jakubowice Konińskie. In addition, 3 series of microbiological analysis were conducted in 2020. Electrolytic conductivity, total phosphorus, nitrate-nitrogen and sulfates constituted the physicochemical indicators of poor water quality in the river. Their average values exceeded the standards for the 2nd class of water quality. High concentration of these indicators, especially of the total phosphorus, could have been related to the influx of domestic wastewater from agricultural holdings, wastewater flows from agricultural areas as well as soil erosion and leaching. The levels of E. coli bacteria and fecal coliform allocated the Ciemięga River waters to the 4th class of water quality and could result from domestic wastewater flow to the river. In order to improve the water quality of the Ciemięga River, it is necessary to reduce or eliminate point and non-point sources of pollution by means of streamlining of the agricultural areas fertilization, regulating the water and wastewater management, regulating of the waste management, as well as the appropriate spatial policy and landscaping of the water catchment areas.

The paper presents the current state of water supply and sewerage infrastructure and the need for its expanding in Radzyń district. The district is located in the northern part of Lublin Voivodeship in Poland. The following communes belong to Radzyń district: the municipal commune of Radzyń Podlaski and 7 rural communes: Borki, Czemierniki, Kąkolewnica, Komarówka Podlaska, Radzyń Podlaski, Ulan-Majorat, Wohyń. The data show that the water supply network in Radzyń district is well developed. The most significant percentage of the population using the water supply network has the rural commune of Radzyń Podlaski – 99.9%, while the smallest, commune Komarówka Podlaska – 54.5%. The survey showed that there was a very large disproportion between the development of the sewerage and water supply systems. The largest percentage of the population using the sewerage network has the municipal commune of Radzyń Podlaski – 99.7%. The smallest percentage of users of collective sewage disposal systems was recorded in the rural commune of Radzyń Podlaski (7.2%). The commune of UlanMajorat does not have a sewerage system. The survey conducted in 2016 shows that 8 collective wastewater treatment plants operated in Radzyń district at that time. The total capacity of the treatment plants is over 5,300 m3/d. In 2016, Radzyń district had about 1,000 household wastewater treatment plants. The presented data show that the condition of the sanitary infrastructure in rural communes of Radzyń district is unsatisfactory and requires the investment activities mainly aimed at expanding collective sewage disposal and treatment systems as well as developing a network of household wastewater treatment plants.

The aim of this paper was to present the current state and the need for development of the sanitary infrastructure in the communes of the Bialski District located in the Lublin Voivodeship. The Bialski District encompasses 2 urban communes: Miedzyrzec Podlaski and Terespol and 17 rural communes: Biała Podlaska, Drelów, Janów Podlaski, Kodeń, Konstantynów, Leśna Podlaska, Łomazy, Międzyrzec Podlaski, Piszcząc, Rokitno, Rossosz, Sławatycze, Sosnówka, Terespol, Tuczna, Wisznice and Zalesie. The present paper uses the data from the surveys conducted in these communes in 2016. On average, 79.2% of the population used the water supply system in the surveyed communes, while 39.4% of the inhabitants had the possibility of discharging wastewater to the sewerage system. In the area of the communes, there were 20 collective, mechanical and biological wastewater treatment plants with a capacity exceeding 5 m3/d. The households which were not connected to the wastewater network, discharged wastewater mainly to non-return tanks. In the surveyed communes, there were 4437 household wastewater treatment plants. Most of them (above 80%) were the systems with infiltration drainage, which do not ensure high efficiency of pollutants removal and may even contribute to the degradation of the groundwater quality. In order to solve the existing problems of wastewater and water management occurring in the communes where the Bialski District is located, it is necessary to further develop collective wastewater systems and equip the areas characterized by dispersed housing with highly efficient household treatment plants, e.g. constructed wetlands.

The aim of the study was to assess the concentration of salinity indicators in the Bystrzyca River in the city of Lublin, located in south-eastern Poland. The studies on the quality of water from the river were carried out from November 2018 to June 2019, i.e. in winter and spring. The water samples for analysis were taken from 9 measurement points located on the river under bridges and at high traffic roads. In total, 8 series of analyses were carried out, during which 72 water samples from the Bystrzyca River were examined. The samples were analyzed in terms of: water temperature, pH value, conductivity as well as concentration of chlorides and sulfates. An increase in both the specific conductivity and chloride and sulfate concentrations was found in the water from the Bystrzyca River during the period of low air temperatures (≤0°C), i.e. in December 2018 and January 2019. This may be a result of winter road maintenance procedures, i.e. by using salts for their defrosting. At the same time, an increase in the conductivity value and the concentration of chlorides and sulfates was observed with the course of the river, which indicates that the pollution generated in the city of Lublin has a negative impact on the water quality in the studied river. The salinity of the Bystrzyca River was greatly affected by the operation of the municipal wastewater treatment plant in Hajdów, especially by the use of coagulants: polyglycol chloride (PAX 18) and iron sulfate (PIX 113).

The paper presents an evaluation of the pollutant removal efficiencies of four primary settling tanks that were components of on-site domestic wastewater treatment plants located in the Roztocze National Park in Poland. We studied two four-chamber settling tanks which were elements of the technological lines of activated sludge treatment plants, and two threechamber settling tanks which provided primary treatment in hybrid constructed wetlands. The tests were conducted in the years 2017–2019. During this period, wastewater samples for analysis were collected from the first chamber (raw wastewater) and the last chamber (primary settled wastewater) of each settling tank. We tested the following pollution parameters: total suspended solids (TSS), BOD5, COD, total nitrogen (TN), and total phosphorus (TP). The following mean pollutant removal efficiencies were obtained for the four-chamber settling tanks: TSS – 68.3%, BOD5 – 50.4%, and COD – 49.5%; the three-chamber settling tanks were much less efficient at reducing those pollution parameters: 50.9%, 17.0%, and 2.3%, respectively. Neither the three-chamber nor the four-chamber settling tanks ensured effective elimination of biogenic compounds. In most cases, the concentrations of TN and TP in primary settled wastewater were higher compared to raw sewage, which means that these elements were being released from sewage sludge during treatment. Despite this finding, the study shows that a primary settling tank should be used as a basic component of any domestic wastewater treatment plant, as it ensures a considerable reduction in TSS and organic matter.

The aim of the work was to analyze the efficiency and reliability of pollutants removal (total suspended solids – TSS, BOD5, COD) in a collective wastewater treatment plant with activated sludge and hydroponic lagoon during its long term operation. The tested object was designed to treat wastewater inflowing through the sewerage system and wastewater delivered by the septic truck. The projected capacity of the treatment plant was 1200 m3d-1. The technological system for wastewater treatment consisted of a mechanical part, a flowing biological reactor working according to the BARDENPHO process, a secondary settling tank and a hydroponic lagoon. The efficiency and reliability of pollutants removal in the analyzed treatment plant were assessed on the basis of the data concerning influent and effluent wastewater collected during the years 2011–2018. On the basis of the measurements results, there were determined characteristic values of the selected pollution indicators in wastewater and the average efficiency of pollutants removal. The technological reliability of the wastewater treatment plant was assessed for the basic pollution parameters (BOD5, COD, TSS) in accordance with the elements of the Weibull’s reliability theory, with regard to normative values of the indicators specified in the Regulation of the Minister of Environment. The analysis was carried out using the Statistica 13.1 software. It was proved that in the wastewater treatment plant with an activated sludge and hydroponic lagoon the level of organic pollutants removal expressed by BOD5 was on average 99.5%, COD – 98.1% and TSS – 99.4%. The technological reliability of the system was 100% in terms of the removal of pollutants from the basic group, which means that during the long term operation (8 years) it provided failure-free operation and guaranteed the fulfillment of the requirements that can be found in the Polish law regulations concerning the analyzed pollutants.

A comparison of two methods of radiocarbon age determination of groundwater is presented. The simplest Pearson model and the “user-defined” option of the NETPATH program were considered. Both methods were used to determine the age of water from a PZ-2 piezometer that is situated in the foreground of chamber Z-32 in Wieliczka Salt Mine. Results of these calculations clearly demonstrate that 14C ages obtained by the Pearson model can be significantly overestimated in comparison with those determined by the NETPATH code. Without additional data, such as the stable isotope composition of the water, conclusions on the age of the groundwater based solely on the Pearson model may be highly inadequate.

Content available remote Isotopic composition of precipitation in Poland: a 44-year record
EN
Isotopic composition of precipitation (2H/1H and 18O/16O isotope ratios, tritium content) is nowadays widely used in numerous applications of environmental isotopes—most notably in hydrology, climatology and biogeochemistry. Here we present a long record (44 years) of stable isotope composition and tritium content in monthly precipitation available for the Krakow station (southern Poland). Krakow is the only site in Poland for which long-term record of the isotopic composition of monthly precipitation is available. The tritium data are discussed here in the context of generally declining levels of bomb tritium in the global atmosphere and growing influence of technogenic emissions of this isotope. Two aspects of temporal variability of stable isotope composition of precipitation collected in Krakow are discussed here: (i) seasonality and (ii) interannual changes of δ18O and δ2H signal. Whereas the seasonality of stable isotope signal is generated mainly by seasonally varying the degree of rainout of air masses bringing moisture from the source regions (subtropical Atlantic Ocean) to the centre of the European continent, the North Atlantic Oscillation seems to govern interannual changes of δ18O and δ2H on the decadal timescale. Progressing warming of the local atmosphere, in the order of 1.8 °C in the past four decades, leaves its imprint in stable isotope signal measured in Krakow precipitation; the slope of isotope–temperature relationship is in the order of 0.50‰/°C for δ18O and 3.5‰/°C for δ2H.
