Funkcjonowanie systemu ochrony wód podziemnych w Polsce w świetle przepisów ustawy Prawo wodne
Ramowa Dyrektywa Wodna wprowadziła wysoki priorytet dla ochrony zasobów wodnych, co w polskim prawodawstwie zostało zaimplementowane najpierw ustawą z dnia 18 lipca 2001 r. – Prawo wodne, a następnie uzupełnione ustawą z dnia 20 lipca 2017 r. – Prawo wodne. Wody podziemne, stanowiące strategiczne rezerwy zasobów wodnych oraz podstawę zaopatrzenia ludności w wodę do spożycia, zajmują szczególną pozycję w systemie ochrony wód. Celem ochrony wód podziemnych jest osiągnięcie celów środowiskowych, odnoszących się zarówno do stanu ilościowego (ochrona ilościowa) jak i chemicznego (ochrona jakościowa). Określone cele środowiskowe są osiągane poprzez wdrażanie programów działań w planach gospodarowania wodami na obszarach dorzeczy, przy równoczesnej realizacji przepisów odrębnych dotyczących ochrony środowiska. W artykule przedstawiono zasady i instrumenty prawne służące ochronie wód podziemnych, w świetle przepisów ustawy Prawo wodne, a także aktualny stan zasobów wód podziemnych w Polsce na podstawie wyników oceny stanu jednolitych części wód podziemnych
Flora of vascular plants of selected Poznań cemeteries

Identifying causes of poor water quality in a Polish agricultural catchment for designing effective and targeted mitigation measures
The Gowienica Miedwiańska catchment is a small agricultural catchment located in the NW of Poland draining into Lake Miedwie, on which a drinking water source for the city of Szczecin is located. The catchment is characterized by very rich soils. Subsequently, agriculture is intensive and this is thought to influence the poor water quality in the local area. Despite more than 20 years since first programmes of measures towards protection of water quality have been introduced into the catchment, these have not been produced the expected results, and the local farming community cites other sources such as poor sewage management rather that agricultural activity, as responsible for this problem. Evaluation of flow pathways in the catchment and identification of the areas responsible for the highest impact on local water quality was therefore conducted within the EU funded project Waterprotect. The aim of this study was to clarify sources of pollution precisely in space and time, in order to increase trust from stakeholders, so that targeted measures can be used effectively to improve water quality. The study included water quality monitoring, isotopic analysis and numerical flow modelling. Results showed that water quality in the catchment is spatially and temporally variable. 93% of nitrogen loadings into the Miedwie lake have been attributed to agriculture and only 7% to wastewater inputs. The local hydrology and hydrogeology play an important role in the distribution of the impacts from these inputs. As a result, three sub-catchments were identified which are differentiated by dominant pollution source, land use, and hydraulic characteristics. The highest inputs from agriculture have been identified in the most upper sub-catchment and this area have been pointed out as most suitable for implementation of agricultural best management practices towards protection of water quality at a local level

Revision of EU directives on water resources management – plans of the European Commission regarding the amendment of EU water policy
Dyrektywa Parlamentu Europejskiego i Rady z dnia 23 października 2000 r. ustanawiająca ramy wspólnotowego działania w dziedzinie polityki wodnej (tzw. Ramowa Dyrektywa Wodna – RDW) miała na celu uporządkowanie ustawodawstwa unijnego w zakresie zarządzania zasobami wodnymi wspólnoty europejskiej. Określone w niej podejście do gospodarki wodnej oparte jest na dorzeczach jako naturalnych jednostkach środowiska, a nie na granicach administracyjnych lub prawnych. Dyrektywa ta zawiera odniesienia do kilku powiązanych dyrektyw, których wdrożenie ujmuje się jako wymóg minimalny. Działania służące do ich wprowadzenia powinny zostać ujęte przez państwa członkowskie w planach gospodarowania wodami w dorzeczach (PGW), realizowanych w sześcioletnich cyklach planistycznych. Warto podkreślić, że RDW była pierwszym aktem legislacyjnym UE traktującym w sposób kompleksowy zagadnienie ochrony zasobów wodnych wraz z ochroną ekosystemów wodnych i lądowych od wód zależnych, a także społeczno-gospodarczych efektów susz i powodzi. Nałożyła ona na państwa członkowskie obowiązek racjonalnego wykorzystywania i ochrony zasobów wodnych w myśl zasady zrównoważonego rozwoju. Po blisko 20 latach obowiązywania RDW oraz dyrektyw powiązanych nastąpił moment rewizji unijnego prawodawstwa, które w wielu obszarach z jednej strony wydaje się niewystarczające, a z drugiej – przeregulowane. Nie bez znaczenia są problemy wśród państw członkowskich związane z jego pełną implementacją oraz, co ważniejsze, niepełne osiągnięcie pierwotnie zakładanych celów RDW. W 2017 r. Komisja Europejska rozpoczęła przegląd i kontrolę sprawności dyrektyw UE regulujących politykę wodną, w efekcie czego w nadchodzących miesiącach jest spodziewana nowelizacja części dyrektyw. Zmiany w dyrektywach unijnych będą musiały zostać transponowane do przepisów krajowych.The Directive of the European Parliament and of the Council of 23 October 2000 establishing a framework for community action in the field of water policy (the so-called Water Framework Directive – WFD) aimed to streamline EU legislation in the field of water management of the European community. The approach to water management laid down in the directive is based on river basin management as natural units of the environment rather than on administrative or legal borders. This directive contains references to several related directives, implementation of which is included as a minimum requirement. Measures to implement them should be included by Member States in river basin management plans (RBMPs) developed and implemented for 6-year water planning cycles. It is worth noting that the WFD was the first EU legislation treating in a comprehensive and holistic way the issue of water resources protection together with the protection of water-dependent ecosystems as well as socio-economic effects of droughts and floods. It imposed on Member States the obligation of a rational use and protection of water resources in accordance with the principle of sustainable development. Almost 20 years after the implementation of the Water Framework Directive and related directives, the time has come for the revision of the EU waterrelated legislations, which in many areas proved to be insufficient and in others - over-regulated. Not without significance are problems among Member States to fulfil the implementation rules and, more importantly, the incomplete achievement of the original WFD objectives. In 2017, the European Commission launched a review process and control of the efficiency of EU directives governing water policy, which will result in the revision of some directives in the coming months
Yesterday, today and future of hydrogeology at the Polish Geological Institute
The Polish hydrogeology had started its development at the end of the 19th century, before Poland was liberated. The needs for country restoration after the world war and for ensuring water supply for communities and industry required construction of many water intakes and water reservoirs. On the other hand, the development of ore deposits, e.g. hard coal seams, needed dewatering of mines and quarries. The Polish pioneer hydrogeologist was R. Rosłoński (1880-1956). He organized the Hydrology Department at the Polish Geological Institute (PGI) in 1919. After World War II, the Hydrogeology and Engineering Department was established at the Geological Institute in Warsaw. Dozent F. Rutkowski was the head of the unit for more than 10 years. Professors C. Kolago, J. Malinowski, A. Różkowski and B. Paczyński introduced in practice a number of hydrogeological studies, including hydrogeological cartography, groundwater resource balances, recognition of groundwater resources of well fields and hydrogeological units of Poland, mining hydrogeology, and the principles of groundwater protection in Poland. Hydrogeological data banks were also first introduced at the PGI. The last 20 years of hydrogeology at the PGI were strongly connected with Poland's accession to the European Union and with the implementation of European directives to the water management system in practice. For this reason, the state hydrogeological survey has been established at the PGI
Origin and development of the Polish Hydrogeological Survey in the Polish Geological Institute
Within the framework of the Poland’s preparation to join the EU, it was necessary to establish new surveys and specialized organizations to cope with tasks to implement the water management policy defined in the Water Framework Directive approved by the European Parliament and Council in 2000. The establishment of the Polish Hydrogeological Survey (PHS) by the Water Act of 18 July 2001 imposed an obligation on the Polish Geological Institute to identify, balance and protect the groundwater as well as to define the principles of the sustainable water management in the river basins. Taking into account the achievements of the Department of Hydrogeology and Engineering Geology, the PGI was well prepared to fulfil the tasks of the PHS in every way: both professional and organizational one. From the mid 1970s the groundwater monitoring has been organized by the Institute as a hydrogeological stationary observation network in Poland. The cartographic projects run by the Institute and the Institute digital data bases with a huge amount of the hydrogeological data collected till 2000 have been very useful to the PHS activity. In subsequent 17 years the PHS has run on annual basis more than 30 permanent tasks as well as more than 10 many years projects essential for the national groundwater management. Until the end of 2017, the PHS activity had been funded by the National Fund for the Environment Protection and Water Management. Currently after the water management reform by the Water Act of 20 July 2017, the PHS is supervised by the competent minister for the water management (The Minister of Marine Economy and Inland Sailing), while funding is now by the National Water Authority Polish Waters
