Our research on the closed elongated depressions (CEDs) of the Jedwabno test field (Szuć site, north‐east Poland) focuses on explaining their origins and their post‐glacial history. This region was covered by an ice sheet and glacitectonically active during the Vistulian, and at least some surface fractures are possible witnesses to this activity. Using geomorphological mapping, sedimentological and geophysical research, we assumed it was related that the origin of these features here is associated with groundwater migration at the end of the Vistulian glaciation or later when groundwater flow intensified due to a rapid climate warming that caused permafrost to melt. The thawing of permafrost caused to transition from continuous permafrost to discontinuous, which in turn cr...

The communities were assessed with 16S rRNA gene sequencing (MiSeq, Illumina) and microscopic methods. The microbial cell density determined by direct cell count was at the order of magnitude of 10 7 cells/mL. It was found that increasing salt concentration was positively correlated with both the cell counts, and species-level diversity of bacterial and archaeal communities. The archaeal community was mostly constituted by members of the phylum Euryarchaeota, class Halobacteria and was dominated by Halorubrum-related sequences. The bacterial community was more diverse, with representatives of the phyla Proteobacteria and Bacteroidetes as the most abundant. The proportion of Proteobacteria decreased with increasing salt concentration, while the proportion of Bacteroidetes increased significantly in the more concentrated samples. Representatives of the genera Idiomarina, Psychroflexus, Roseovarius, and Marinobacter appeared to be tolerant to changes of salinity. During the brine concentration, the relative abundances of Sphingobium and Sphingomonas were significantly decreased and the raised contributions of genera Fabibacter and Fodinibius were observed. The high proportion of novel (not identified at 97% similarity level) bacterial reads (up to 42%) in the 16S rRNA gene sequences indicated that potentially new bacterial taxa inhabit this unique environment.

It is constitutes one of the largest forest complexes in the northern part of Poland, which belongs to the plains of Central Europe. It is situated in the postglacial area within the range of the Weichselian glaciation (Last Glaciation, Vistulian).  The study aims to provide a qualitative assessment of geodiversity by evaluation of abiotic nature objects. The geotourist evaluation of the geosites in TFBR has been conducted on the basis of the criteria proposed by Dmytrowski and Kicińska with modifications by authors. The geotouristic evaluation of 32 geosites, including mining heritage, petrological, sedimentological, geomorphological  as well as hydrological and hydrogeological sites, located in the area of Tuchola Forest Biosphere Reserve (TFBR). The evaluated geosites represent both perfect examples of typical features for the physiography of the TFBR as a young glacial landscape and values proving the uniqueness of the area on both regional and international scale. The authors proposed geosites that require improving their accessibility to enhance the geotourist attractiveness, recognized the necessity of marking out geotourist trails in the most attractive and diversified areas, and noticed the influence of extreme weather phenomena (whirwinds) on changes in geotourist attractiveness of some geosites. It is believed that the results of the conducted evaluation may favorably affect the importance, position and publicity of the whole area by supplementing the well-recognized biodiversity with geodiversity presented in the study.</p>

This transformation was accompanied by the supply of considerable quantities of meltwaters in glacial lakes in the southern periphery of the Scandinavian ice sheet. Their sudden release was responsible for the development of the Megaflood Landform System in north-eastern Poland which includes floodwater flow pathways represented by the Western and Eastern Spillways (Weckwerth et al., 2019). In the proximal part of the Western Spillway, the Bachanowo and Szeszupka Outburst Fans developed, while scabland-like topography was formed at the front of the Prudziszki Gate in proximal part of the Eastern Spillway. Bachanowo and Szeszupka Outburst Fans have surface characterized by the existence of subsequent bedforms, which include (1) streamlined bars developed as downstream elongated ridges and separated by channels of the braiding pattern, (2) scours with channel lag sediments deposited from traction carpet and gravel bedload sheets, (3) scour infills originated due to hydraulic jumps, and (4) expansion bars or chute bars evolved during the waning flood stage. These bars consist of sheet-like beds dipping downstream, and were formed due to low-angle forests progradation under condition of pulsed deposition from the traction carpet and fast sheetflows, the energy of which gradually decreased.

We wrześniu 2019 r. w Toruniu odbyło się Sympozjum z cyklu "Współczesne problemy hydrogeologii", które odbywa się cyklicznie od blisko czterdziestu lat. Podczas dwóch dni obrad zaprezentowano ponad 35 referatów naukowych poruszających zagadnienia regionalnych badań hydrogeologicznych, użytkowania i ochrony zasobów wód podziemnych, a także badań ich składu chemicznego i izotopowego. Nie zabrakło również miejsca na prezentację nowoczesnych metod badawczych oraz technik terenowych i laboratoryjnych, a także modelowania przepływu wód podziemnych i transportu zanieczyszczeń. Podczas dyskusji była poruszana również kwestia roli i pozycji hydrogeologii w gospodarce wodnej kraju po reformie wprowadzonej ustawą Prawo wodne z dnia 20 lipca 2017 r. Na zakończenie obrad Sympozjum została powołana Komisja Wnioskowa pod kierunkiem prof. dr hab. inż. Andrzeja Szczepańskiego, do której zostali zaproszeni: dr hab. inż. Arkadiusz Krawiec prof. UMK, prof. dr hab. Ewa Krogulec, prof. dr hab. Jan Przybyłek, prof. dr hab. Andrzej Sadurski, prof. dr hab. Stanisław Staśko i dr Małgorzata Woźnicka. Członkowie Komisji przeanalizowali wnioski zgłoszone przez autorów artykułów, wyniki dyskusji panelowych oraz wzięli pod uwagę własne przemyślenia na temat najbardziej istotnych problemów stojących przed hydrogeologami w kraju, w celu uwypuklenia ważnych zadań, jakie obecnie pojawiły się w obszarze użytkowania i ochrony zasobów wód podziemnych. Odniesiono się m.in. do publikacji międzynarodowych organizacji zajmujących się gospodarką i zmianami środowiskowymi, które wskazują, że w latach 20-30. XXI wieku niedobór słodkiej, czystej wody w wielu regionach świata, w tym i na kontynencie europejskim, może spowodować kryzys skutkujący ograniczeniem produkcji żywności i energii. Według ekspertów opracowujących Global Risk Report, rozpoczynający się kryzys wodny może stać się największym zagrożeniem dla świata. Ten wniosek potwierdziło obradujące w sierpniu 2018 r. Światowe Forum Ekonomiczne (World Economic Forum), które uznało za najbardziej prawdopodobny kryzys wodny w nadchodzącej dekadzie XXI w. Organizacja Narodów Zjednoczonych ustanowiła "Międzynarodową dekadę wody 2018-2028" pod hasłem "Woda dla zrównoważonego rozwoju" (The quest for water), co także wskazuje na duże zainteresowanie organizacji międzynarodowych problematyką gospodarki wodnej. Rosnące trudności w zaspokojeniu potrzeb wodnych ludności, rolnictwa i przemysłu na świecie oraz malejące zasoby wód o dobrym stanie chemicznym budzą poważne obawy ekspertów organizacji między narodowych, zwłaszcza wobec prognozowanych zmian klimatu. W Polsce strategiczne rezerwy zasobów wód stanowią wody podziemne, z których pochodzi ponad 70% wody przeznaczonej do spożycia przez ludzi. Przed hydrogeologami istnieją zatem nowe i skomplikowane zadania ukierunkowane na zrównoważone gospodarowanie zasobami wód podziemnych, przy szerokiej współpracy z hydrologami, hydrotechnikami i przyrodnikami, co jest szczególnie istotne wobec przyjętej w Unii Europejskiej zasady holistycznego podejścia do gospodarki wodnej.

The focus of the study was to develop a conceptual model that will be used in further investigation to create a hydrogeological model. In the intake area two multi-aquifer formations have been distinguished: Quaternary and Paleocene-Cretaceous. The Quartenary multi-aquifer formation, which consists of two aquifers separated by poorly permeable rocks, is primary utility. Groundwater in the Paleocene-Cretaceous aquifer has an elevated mineral content, which makes it not usable. The intake is located near Grudziądz and areas of intense farming, which leads to a hazard of anthropopressure, and may have a negative impact on the groundwater quality and quantity. In-office work conducted for the preparation of article included gathering and description of archival data from over 120 years of intake existence. Data from 53 hydrogeological boreholes have been analyzed. In 2017, field work was also conducted, including several measurements of water table in wells and piezometers of the intake. Water samples have also been collected for chemical analyses. An efficiency assessment of some observation wells has been made, establishing their hydrogeological parameters using the PARAMEX method.

It has been shown that the properties of the waters were most strongly affected by the specific geological structure (the city is located within the Zechstein salt dome) as well as the long-term influence of a salt mine and soda plant. The composition of most analysed samples was dominated by Ca 2+ , Na + and Clions. In places of heavy industrial activity, some water parameters were several time higher than permissible limit values according to Polish standards. It is concluded that, due to the threat to the city's drinking groundwater resources and fertile soils, the surface water and groundwater in the area in question require permanent monitoring.

Methods: Water samples were collected from three thermal saline baths, supplied by thermal saline waters (type Cl - Na). The total number of bacteria was determined in the direct microscopic count under a fluorescence microscope The numbers of bacteria belonging to different phylogenetic groups (Eubacteria, Legionella sp. and Legionella pneumophila) were determined with the use of a molecular FISH method. Results: The highest average total number of bacteria as well as the highest average number of Eubacteria in the entire research cycle was recorded in bath 1. Bacteria belonging to the Legionella genus along with Legionella pneumophila were identified in all water samples collected from each bath. Moreover, biofilm containing cells of L. pneumophilla was identified in the collected water samples. Conclusion: The number of bacteria in water increases with the bath's age. The Legionella pneumophila can successfully develop not only in fresh water bodies but in thermal saline baths as well. Still, it is uncertain whether the commonly applied culture method, developed for freshwater bodies, is also suitable for thermal saline baths.

The crucial date in Ciechocinek's history was 1836, when four treatment copper bath tubs were installed in the local inn. This gave rise to the beginning of the Health Springs Enterprise, which was the origin of the Health Resort. The graduation towers of Ciechocinek are particular and they are the biggest wooden constructions which serve to vaporize brine's water from the spring no. 11. The graduation towers were built in the shape of a horseshoe. Two first graduation towers were built in the years between 1824 and 1828 and the third in 1859. The height of towers is about 15.8 m and the total length of all of them is more than 1741.5 m. They constitute a unique monument of the nineteenth-century technology, one of few in Europe. In the graduation towers the concentration of salt brine takes place as a part of the salt production process. A characteristic feature of this process is the production of a natural aerosol with healing properties. Within the graduation towers there is a specific microclimate, a natural and curative inhaler. The technology of salt production, which is based on heating concentrated salt brine, has not changed in 190 years-it consists in heating concentrated brine. Thermal brines of the Na-Cl type and J type from borehole no. 14 (Terma 14) and borehole no. 16 (Terma 16) are used for Ciechocinek Spa mineral water supply. These boreholes are screened in the Dogger and Lias sandstones. The water in Terma 14 has mineralization (total dissolved solids (TDS)) of 43.5 g/L and the temperature on the borehole outflow is 28 °C. The water from Terma 16 has mineralization (TDS) of 53.4 g/L. It is thermal water and its temperature on the borehole outflow is 32 °C. The therapeutic thermal water in the Ciechocinek boreholes occurs at considerable depth and its resources are very slowly renewable. The therapeutic qualities of Ciechocinek springs are strongly recommended for curing cardiovascular, respiratory, orthopedic, traumatic, rheumatic, nervous system, and women's diseases. The Ciechocinek Spa is a producer of well-known products of perfect quality: "Krystynka" mineral water, flavored water, table salt, medicinal lye, and mud.

Analizie poddano wcześniejsze dane chemiczne i izotopowe, jak i wyniki własnych badań tych wód. Są to prawdopodobnie głównie wody paleoinfiltracyjne z okresów przedczwartorzędowych. Na możliwość zasilania w klimatach ciepłych wskazuje ich skład izotopowy. Wskaźniki chemiczne CrlBri Br-/J wskazują na dominację zasolenia pochodzącego z ługowania utworów solonośnych. Wykazano, że wody z niektórych ujęć mają stały skład chemiczny, lecz w wodach ze wszystkich opróbowanych ujęć zaznacza się tendencja do zmian składów izotopowych w kierunku niższych wartości 0 18 0 i oD. Słowa kluczowe: lecznicze wody mineralne; badania izotopowe i hydrogeochemiczne; wiek i geneza wód Arkadiusz Krawiec-New results of the isotope and hydrochemical investigations of therapeutical waters of Ciechocinek Spa.

We wrześniu 2019 r. w Toruniu odbyło się Sympozjum z cyklu "Współczesne problemy hydrogeologii", które odbywa się cyklicznie od blisko czterdziestu lat. Podczas dwóch dni obrad zaprezentowano ponad 35 referatów naukowych poruszających zagadnienia regionalnych badań hydrogeologicznych, użytkowania i ochrony zasobów wód podziemnych, a także badań ich składu chemicznego i izotopowego. Nie zabrakło również miejsca na prezentację nowoczesnych metod badawczych oraz technik terenowych i laboratoryjnych, a także modelowania przepływu wód podziemnych i transportu zanieczyszczeń. Podczas dyskusji była poruszana również kwestia roli i pozycji hydrogeologii w gospodarce wodnej kraju po reformie wprowadzonej ustawą Prawo wodne z dnia 20 lipca 2017 r. Na zakończenie obrad Sympozjum została powołana Komisja Wnioskowa pod kierunkiem prof. dr hab. inż. Andrzeja Szczepańskiego, do której zostali zaproszeni: dr hab. inż. Arkadiusz Krawiec prof. UMK, prof. dr hab. Ewa Krogulec, prof. dr hab. Jan Przybyłek, prof. dr hab. Andrzej Sadurski, prof. dr hab. Stanisław Staśko i dr Małgorzata Woźnicka. Członkowie Komisji przeanalizowali wnioski zgłoszone przez autorów artykułów, wyniki dyskusji panelowych oraz wzięli pod uwagę własne przemyślenia na temat najbardziej istotnych problemów stojących przed hydrogeologami w kraju, w celu uwypuklenia ważnych zadań, jakie obecnie pojawiły się w obszarze użytkowania i ochrony zasobów wód podziemnych. Odniesiono się m.in. do publikacji międzynarodowych organizacji zajmujących się gospodarką i zmianami środowiskowymi, które wskazują, że w latach 20-30. XXI wieku niedobór słodkiej, czystej wody w wielu regionach świata, w tym i na kontynencie europejskim, może spowodować kryzys skutkujący ograniczeniem produkcji żywności i energii. Według ekspertów opracowujących Global Risk Report, rozpoczynający się kryzys wodny może stać się największym zagrożeniem dla świata. Ten wniosek potwierdziło obradujące w sierpniu 2018 r. Światowe Forum Ekonomiczne (World Economic Forum), które uznało za najbardziej prawdopodobny kryzys wodny w nadchodzącej dekadzie XXI w. Organizacja Narodów Zjednoczonych ustanowiła "Międzynarodową dekadę wody 2018-2028" pod hasłem "Woda dla zrównoważonego rozwoju" (The quest for water), co także wskazuje na duże zainteresowanie organizacji międzynarodowych problematyką gospodarki wodnej. Rosnące trudności w zaspokojeniu potrzeb wodnych ludności, rolnictwa i przemysłu na świecie oraz malejące zasoby wód o dobrym stanie chemicznym budzą poważne obawy ekspertów organizacji między narodowych, zwłaszcza wobec prognozowanych zmian klimatu. W Polsce strategiczne rezerwy zasobów wód stanowią wody podziemne, z których pochodzi ponad 70% wody przeznaczonej do spożycia przez ludzi. Przed hydrogeologami istnieją zatem nowe i skomplikowane zadania ukierunkowane na zrównoważone gospodarowanie zasobami wód podziemnych, przy szerokiej współpracy z hydrologami, hydrotechnikami i przyrodnikami, co jest szczególnie istotne wobec przyjętej w Unii Europejskiej zasady holistycznego podejścia do gospodarki wodnej.

The focus of the study was to develop a conceptual model that will be used in further investigation to create a hydrogeological model. In the intake area two multi-aquifer formations have been distinguished: Quaternary and Paleocene-Cretaceous. The Quartenary multi-aquifer formation, which consists of two aquifers separated by poorly permeable rocks, is primary utility. Groundwater in the Paleocene-Cretaceous aquifer has an elevated mineral content, which makes it not usable. The intake is located near Grudziądz and areas of intense farming, which leads to a hazard of anthropopressure, and may have a negative impact on the groundwater quality and quantity. In-office work conducted for the preparation of article included gathering and description of archival data from over 120 years of intake existence. Data from 53 hydrogeological boreholes have been analyzed. In 2017, field work was also conducted, including several measurements of water table in wells and piezometers of the intake. Water samples have also been collected for chemical analyses. An efficiency assessment of some observation wells has been made, establishing their hydrogeological parameters using the PARAMEX method.

It has been shown that the properties of the waters were most strongly affected by the specific geological structure (the city is located within the Zechstein salt dome) as well as the long-term influence of a salt mine and soda plant. The composition of most analysed samples was dominated by Ca 2+ , Na + and Clions. In places of heavy industrial activity, some water parameters were several time higher than permissible limit values according to Polish standards. It is concluded that, due to the threat to the city's drinking groundwater resources and fertile soils, the surface water and groundwater in the area in question require permanent monitoring.

Methods: Water samples were collected from three thermal saline baths, supplied by thermal saline waters (type Cl - Na). The total number of bacteria was determined in the direct microscopic count under a fluorescence microscope The numbers of bacteria belonging to different phylogenetic groups (Eubacteria, Legionella sp. and Legionella pneumophila) were determined with the use of a molecular FISH method. Results: The highest average total number of bacteria as well as the highest average number of Eubacteria in the entire research cycle was recorded in bath 1. Bacteria belonging to the Legionella genus along with Legionella pneumophila were identified in all water samples collected from each bath. Moreover, biofilm containing cells of L. pneumophilla was identified in the collected water samples. Conclusion: The number of bacteria in water increases with the bath's age. The Legionella pneumophila can successfully develop not only in fresh water bodies but in thermal saline baths as well. Still, it is uncertain whether the commonly applied culture method, developed for freshwater bodies, is also suitable for thermal saline baths.

The crucial date in Ciechocinek's history was 1836, when four treatment copper bath tubs were installed in the local inn. This gave rise to the beginning of the Health Springs Enterprise, which was the origin of the Health Resort. The graduation towers of Ciechocinek are particular and they are the biggest wooden constructions which serve to vaporize brine's water from the spring no. 11. The graduation towers were built in the shape of a horseshoe. Two first graduation towers were built in the years between 1824 and 1828 and the third in 1859. The height of towers is about 15.8 m and the total length of all of them is more than 1741.5 m. They constitute a unique monument of the nineteenth-century technology, one of few in Europe. In the graduation towers the concentration of salt brine takes place as a part of the salt production process. A characteristic feature of this process is the production of a natural aerosol with healing properties. Within the graduation towers there is a specific microclimate, a natural and curative inhaler. The technology of salt production, which is based on heating concentrated salt brine, has not changed in 190 years-it consists in heating concentrated brine. Thermal brines of the Na-Cl type and J type from borehole no. 14 (Terma 14) and borehole no. 16 (Terma 16) are used for Ciechocinek Spa mineral water supply. These boreholes are screened in the Dogger and Lias sandstones. The water in Terma 14 has mineralization (total dissolved solids (TDS)) of 43.5 g/L and the temperature on the borehole outflow is 28 °C. The water from Terma 16 has mineralization (TDS) of 53.4 g/L. It is thermal water and its temperature on the borehole outflow is 32 °C. The therapeutic thermal water in the Ciechocinek boreholes occurs at considerable depth and its resources are very slowly renewable. The therapeutic qualities of Ciechocinek springs are strongly recommended for curing cardiovascular, respiratory, orthopedic, traumatic, rheumatic, nervous system, and women's diseases. The Ciechocinek Spa is a producer of well-known products of perfect quality: "Krystynka" mineral water, flavored water, table salt, medicinal lye, and mud.

Analizie poddano wcześniejsze dane chemiczne i izotopowe, jak i wyniki własnych badań tych wód. Są to prawdopodobnie głównie wody paleoinfiltracyjne z okresów przedczwartorzędowych. Na możliwość zasilania w klimatach ciepłych wskazuje ich skład izotopowy. Wskaźniki chemiczne CrlBri Br-/J wskazują na dominację zasolenia pochodzącego z ługowania utworów solonośnych. Wykazano, że wody z niektórych ujęć mają stały skład chemiczny, lecz w wodach ze wszystkich opróbowanych ujęć zaznacza się tendencja do zmian składów izotopowych w kierunku niższych wartości 0 18 0 i oD. Słowa kluczowe: lecznicze wody mineralne; badania izotopowe i hydrogeochemiczne; wiek i geneza wód Arkadiusz Krawiec-New results of the isotope and hydrochemical investigations of therapeutical waters of Ciechocinek Spa.
