Evaluation of the influence of leachate on underground waters in the vicinity of a chosen landfill is examined in this paper. The purpose of the research was to give information on maximum pollutants concentrations which could penetrate ground and water subsoil and its influence on the area adjacent to the landfill. Scale and range of pollution in the examined area have been observed in 7 piezometer test wells and 4 nearest household wells and analogous parameters have been determined for leachate. To evaluate the influence of leachate on examined ground waters a method of multidimensional factor analysis with Varimax rotation was used.

A method of trivalent and sexivalent chromium speciation in well waters in the city of Poznań was developed. The determinations were performed using atomic spectrophotometric absorption with a graphite cuvette, which involved multiple injection and the CDS (initial tube cooling). The total chromium was determined directly in the collected and acidified samples, while the sexivalent chromium in the extract from a water sample. The extraction was performed using ammonium tetramethylendithiocarbamate (APDC) and methy-isobuthylketone (MIBK) in the presence of a buffer. The trivalent chromium was calculated from the difference between the Cr and Cr(VI). Chromium concentration in underground waters falls between 0.0-5.0 μg/1, with the detection limit for the direct determination method for chromium - 0.01 μg/1. The amount of Cr(VI) ranges from 0.00-1.20 μg/l, with the detection limit for the determination method in extract - 0.01 μg/l.

This study presents the results of an analysis of factors which affect fluorine concentrations in deep water drawn for consumption. The analysis covered two water intakes in Tczew (northern Poland) consisting of 19 wells which supply water from Cretaceous (4), Tertiary (10), and Tertiary and Quaternary (5) horizons. Fluoride concentrations ranged from 0.3 to 2.8 mg·dm-3 with the Maximum Allowable Concentration of 1.5 mg·dm-3. The allowable qualitative standards were exceeded in 38% of the investigated samples. It was found that fluorine concentrations were most profoundly affected by the water-bearing horizon (the highest concentration levels were observed in water drawn from Cretaceous horizons) and well depth. As a general trend, fluorine concentrations increase with depth, but the analysis of water drawn from the same horizon indicates that bottom-layer water may be characterised by a significantly lower fluoride content. The highest fluorine concentrations were reported in water drawn from Cretaceous water-bearing horizons to a depth of 150 m. The mixing of water from various water-bearing horizons proved to be a sufficient measure to obtain water of satisfactory quality with the optimum fluoride concentration.

The persented study attempts to verify a hypothesis on the tectonic conditions of spring distribution and their yield in the western part of the Lublin Upland. The materials used for comparison consists of satellite lineaments map. The relationship between the location of springs and satellite lineament course has been worked out by means of the PC program NIT. The results of calculations carried out show conclusively that the number of springs and theirs yield decreases with the increasing distance from the satellite lineaments.

This paper presents data on conductivity, pH, hardness, NH4-N, N03-N and Mn content in water of 49 selected wells, counts of TVC 20°C, TVC 37°C, TC, FC, FS and CP in water of 302 wells (0.3 - 31.5 m) in 30 localities, and from 8 natural springs in Wigry National Park in northeast Poland. Surveys were carried out twice: in spring and autumn 1995. Conductivity of well water was 360-1430 mS/cm3, pH 7.2-8.6, water hardness 172-544 mval/cm3, content of NH4-N 0-0.21 mg/dm3, N03-N 0-30.00 mg/dm3, Mn 0-1.00 mg/dm3. The majority of the surveyed wells had TVC 20°C. TVC 37°C, TC and FC counts exceeding permissible levels, and very high numbers of FC. Single wells had water containing CP. High numbers of these micro-organisms were present in shallow waters (less than 10 m) as well as in deep wells (more than 10 m). The degree of bacteriological contamination of well waters was usually lower in spring and higher in autumn. Higher bacteriological pollution of well water was often accompanied by higher N03-N concentrations. Natural springs were usually characterised by lower bacteriological contamination than well water.

A number of indicatory microorganisms of contamination (TVC 2Q°C, TVC 37°C) and sanitary (TC, FC, FS, Clostridium perfringens) states were investigated in pig slurry (fresh and stored in a four-lagoon system), the surface water of the drainage ditch in a region fertilized by the slurry, the water of the Łeba River, and in the ground water (shallow and deep) of this region. The highest numbers of indicatory microorganisms were found in fresh slurry. In the case of stored slurry, their numbers decreased 100-1000 times, reaching after one year the values which are permitted for agriculturally utilizing sewage. The highest numbers of indicatory microorganisms were found in the drainage ditch water and in the shallow and deep piezometers neighbouring ring the lagoons.

Contaminations carried by effluents from communal waste dumps are a serious threat to underground waters. The effluents may contain solutes washed away by precipitation and also organic and mineral substances that arise during anaerobic and aerobic waste decomposition. Aside of substances that are known to be harmful to the human health (heavy metals), the effluents may contain a large number of common elements which are not regarded harmful at natural concentrations. In effluents from “young” dumps, where the waste undergoes acidic fermentation mainly, calcium concentration may exceed 3,000 mg⋅dm-3 and that of magnesium reach 1,500 mg⋅dm-3. Effluents from “old” dumps, where methane fermentation dominates, most often contain up to 400 mg⋅dm-3 of calcium and 200 mg⋅dm-3 magnesium. The aim of the work was to elucidtyate the character and dynamics of changes in concentration of the elements studied in effluents from a municipal waste dump at Maoelice near the city of Wrocław, and in underground waters of the adjacent land. Deposition of waste in this area began in the late 1960s. The ground conditions provide for an easy contact between underground water and dumped waste, and transport of the washed-out pollutants. Only part of the dump has sealing and drainage that conducts the effluents to a reservoir, where samples for this study were taken. At the turn of 1999 and 2000 the utilization of the dump was terminated and its reclamation began. Thus, the slopes of the refuse heap were fortified with reinforced ground, the cap sealed with synthetic-mineral material, and from the side of underground water inflow a shield was made (in 2002) that reached down to the impermeable ground layer in order to stop the inflowing waters. In 2004 the reservoir for effluents was filled in. The results, presented in this report, on the content of calcium and magnesium in underground waters flowing into the dump did not show any other extra contamination. In dump effluents the relations between calcium and magnesium concentration remained on similar levels. Like for other dumps, in the first years of study calcium concentration prevailed, whereas effluents from older dumps contained greater amounts of magnesium. Increased contents of calcium and magnesium in underground waters flowing under the unsealed part of the dump indicated at continuous inflow of contaminations, that were not eliminated by the technical means applied during reclamation of the installation. Variations in the properties of waters flowing out of the dump depended mainly on the composition of the inflowing waters (max. concentrations occurred concurrently) and the amount of contaminants emitted into the ground from the dump (relations between mean contents of calcium and magnesium varied in them like in the dump effluents).

This work comprises the results of comparative research on the determining the number of heterotrophic bacteria in underground waters of one of the largest Aquifers without isolation from the surface by an impermeable layer on the Mazurian Lake District. Modified Walters and Schwartz's medium and Groundwater Agar prepared on underground water were used for research. The investigations were carried out in the three years 1991-1993. The calculations of heterotrophic bacteria were made after 1, 2, 3, 4, 5 and 6 weeks of sample incubation at temperatures of 4 and 20°C. Maximum numbers of heterotrophic bacteria were regained in both temperatures on Wolters and Schwartz's medium, on both media at 20°C after 4-6 weeks of sample incubation.

Nine underground water springs from the Szczawno-Jedlina health resort and one from Zagorze Śląskie were investigated for natural radioactivity content (²²²Rn, ²²⁶,²²⁸Ra, ²³⁸,²³⁴U). In order to obtain the necessary data, two different nuclear spectrometry techniques were applied: a liquid scintillation counter that enabled us to determine ²²²Rn and ²²⁶,²²⁸Ra isotope content, and α spectrometer for measurements of uranium isotopes (²³⁴,²³⁸U) in investigated samples. The activity concentrations of ²²²Rn in investigated samples varied from 6 Bq/l to 227 Bq/l. For radium isotopes the concentrations ranged from 13 mBq/l to 808 mBq/l for ²²⁶Ra and from below 30 mBq/l to 184 mBq/l for ²²⁸Ra. The activity concentrations for uranium isotopes varied from 2.4 mBq/l to 964 mBq/l for ²³⁴U, and from 1.0 mBq/l to 725 mBq/l for ²³⁸U. The isotopic ratios between uranium and radium isotopes (²²⁶Ra/²²⁸Ra, ²²⁶Ra/²³⁸U, ²³⁴U/²³⁸U) and annual effective doses due to these isotopes’ consumption were evaluated. Risk levels due to carcinogenic effects of ²²⁶,²²⁸Ra and ²³⁴,²³⁸U radionuclides consumed with water were estimated.

Test was done on Arkonka underground water intake. To perform it, it was constructed the model station composed of the closed gravity filter, oxygen supply system, water supply system and a mixer. For needs of the experiment it was determined the iron reduction degree, manganese reduction degree, pH determination, determination of the oxygen contents in treated water. The above determinations were to be helpful in analysis of that innovatory technology. The background for the comparison were the results of the above determinations for the aeration – filtration technological line in use on Arkona water intake. That comparison comprised the analysis of the reductive effectiveness of the particular methods with the comparison of the costs of their industrialscale operation.

Results of analyses of underground waters on a municipal landfill site conducted in 2004-2008, prior to leachate cleaning were presented and discussed in the paper. The sewage quality analysis comprised pH, electrolytic conductivity, TOC, Cr+6, Pb, Cd, Cu, Hg, Zn and PAHs. Results of leachate water testing were compared with standard values and subjected to comparative analysis taking into consideration also atmospheric precipitation amount. The aim of the paper was to assess the leachate water quality in conditions of exploited municipal landfill. The analyzed waters were characterized by variability of composition evidenced by increasing pH values, electrolytic conductivity and heavy metal concentrations (Cr, Hg) total organic carbon (TOC) and PAHs, but also by a decline in heavy metal contents (Pb, Cd, Cu and Zn).

The regional and local monitoring of underground waters as well as general water resource balance studies have encompassed only individual springs in some Polish national parks. This report presents the results of cluster analysis derived from the chemical analyses of spring waters collected in Świętokrzyski (Holy Cross Mountains) National Park in 2004 and 2006. The cluster analysis technique enabled me to obtain information about similarities or differences between sampling sites. This technique also indicated that the division of waters only on the basis of their quality and chemistry was not fully substantiated and required further study.

Na Ukrainie największymi odbiorcami wód podziemnych jako źródła wody pitnej są mieszkańcy zachodniej części kraju. Ze względu na obecność stref pękania skał wodoodpornych w regionach hydrogeologicznych zachodniej Ukrainy skład fizykochemiczny wody nie jest stały i może ulegać zmianie, w szczególności w zakresie zawartości metali ciężkich. Przyczyną ich obecności w wodach podziemnych są oddziaływanie antropogeniczne oraz biologiczne ługowanie rud mineralnych. Metale ciężkie mogą migrować w dół i w górę oraz przenikać do warstw wodonośnych wody pitnej przez pęknięte strefy warstw wodoodpornych. Rudy mineralne występujące na terytorium zachodniej Ukrainy zawierają metale ciężkie, a zdecydowana większość z nich to siarczki. Są one utleniane przez grupę bakterii tionowych (рН 5–7), w wyniku czego stężenie siarczanu w wodzie wzrasta. Jednocześnie na zachodniej Ukrainie powszechnie występują glinokrzemiany (zeolity, tufy, bazalty i inne), które mogą być wykorzystane jako sorbent w technologii uzdatniania wody. W porównaniu z tradycyjnie stosowanym wapnem gaszonym przy wykorzystaniu glinokrzemianów wydajność usuwania metali ciężkich jest większa ze względu na to, że odbywa się za pomocą dwóch mechanizmów – wymiany jonowej i tworzenia wodorotlenków metali ciężkich.
