The results of a long-term water level monitoring in three forest ponds are presented in the paper. The ponds are located in the Wielisławice and Laski forest districts in South Wielkopolska, Poland. Two of the analysed ponds are natural ones supplied by precipitation and the third now is disused artificial fishpond of throughflow water management. Systematic water level measurements, as well as measurement of basic meteorological conditions – precipitation and air temperature – were carried out in the 2000–2016 hydrological period. The basic statistics as well as the trends in long-time changes in water levels, were determined using the nonparametric Mann–Kendall test were calculated. The results obtained were statistically inconclusive, but they indicated downward trends in water levels in the natural ponds and upward trends in water levels in the artificial pond. Although a statistically significant downward trend was observed in only one natural pond, it may suggest some negative changes occurring in the catchment of ponds in general.

This Special Issue describes the main outcomes from the SHEER (SHale gas Exploration and Exploitation induced Risks) project, a 3 year EC Horizon 2020 funded investigation into environmental risk associated with shale oil and gas development within the European Union. A key feature of the programme of work has been the independent monitoring of a shale gas well at Wysin, Poland, through a network of seismic, groundwater and air quality measurement arrays and shallow borehole sensors both in advance of and subsequent to hydraulic fracturing operations. In conjunction with the environmental monitoring programme, a multi-hazard risk assessment technique has been applied to shale gas operations to identify and assess the likelihood of occurrence of incidents and their potential impacts on the surrounding environment. Given the limited development of shale oil and gas in Europe experience out-with the European Union, particularly in the USA and Canada, has been integrated into the project. A further element of the research has been the dissemination of results through academic publications, a large number of presentations to conferences and at SHEER events in Italy, Poland and the UK. This introductory paper provides a brief synopsis of the research and development that has been carried out, with a primary focus on the best practice recommendations, policy guidelines and key learning that have been developed during the course of the project. Policy guidelines include issues of relevance to regulators and government in providing effective regulatory oversight of shale gas operations within the European Union. Recommendations for best practice are primarily related to the monitoring and evaluation of environmental risk in the development of shale gas within the European Union.

Obiekty posadowione na podłożu ekspansywnym ulegają licznym uszkodzenion i wymagają długookresowych obserwacji. Na podstawie wieloletnich obserwacji stwierdzono istotne przemieszczenia pionowe, pomimo przeprowadzonych prac zabezpieczających. W przypadku niektórych obiektów przemieszczenia są zróżnicowane i w związku z tym można zrezygnować z częstych obserwacji części obiektu o nieznaczących przemieszczeniach.

Objects constructed in expansive soil foundation reveal significant damage and require long-term observation. In effect of long-term monitoring, significant vertical displacements that had occurred despite conservation works, were found on the objects. On some objects the displacements are highly diversified and, therefore, observation of the parts with slight displacements can be abandoned.

By using a passive sampler for a long sampling period, it is possible to monitor the pollutant concentration in time. In this paper such an approach has been applied to some organic pollutants in water. A new passive sampler has been designed and examined. After exposing the passive sampler to the pollutants for a certain period of time (varied from days to weeks), its solvent filling was subjected to the analysis by liquid chromatography for the content of these pollutants. The sorption of the analytes took place in 50 L-in-volume containers with water of the known concentration of the selected organic pollutants. Investigations were focused on e phenol-type compounds, some pesticides and herbicides. Several parameters were found to strongly influence the performance of the passive method, i.e. the uptake of the pollutants through different membranes, the filling solvents, and the exposure time in various environments.

Sampling is the first and the most important step of each analysis procedure. It is also the most important because is performed in situ. Presently two groups of techniques of sampling for investigation and monitoring of aqueous environments are usually applied in analytical practice: grab sampling of water; sampling with simultaneous izolation and preconcentration of analytes on the basis of forced flow of liquid sample through a proper trap, for example through a tube with a sorbent. During last years, a good deal of papers appeared proposing a new approach to sampling of liquid samples containing organic analytes. It concerns the application of passive dosimetry, the technique commonly used in air control and monitoring. The paper presents the basic types of passive devices such as: SPM (semipermeable membranes), SPMD (semipermeable membrane devices), PISCES (passive in situ concentration/extraction sampler), SLM (supported liquid membranes). The particular attention is focused on advantages of semipermeable membrane devices SPMD technique.

Pobieranie próbek jest pierwszym i najważniejszym a jednocześnie i najtrudniejszym (bo wykonywanym in situ) etapem każdej procedury analitycznej. W chwili obecnej w praktyce analitycznej znajdują zastosowanie przede wszystkim dwie grupy technik pobierania próbek w zakresie badania i monitoringu środowiska wodnego: pobieranie próbek wody o dużej objętości; pobieranie próbek z jednoczesną izolacją i wzbogacaniem analitów, wykorzystując dynamiczny przepływ ciekłej próbki przez odpowiednio dobrane medium sorpcyjne, np. rurkę wypełnioną stałym sorbentem. W ciągu ostatnich kilku lat pojawiło się sporo prac na temat innego podejścia do zagadnienia pobierania próbek analitów organicznych z badanego medium ciekłego. Dotyczą one wykorzystania dozymetrii pasywnej, techniki, która jest już powszechnie wykorzystywana w zakresie kontroli i monitoringu powietrza. W pracy przedstawiono podstawowe typy urządzeń pasywnych, do pobierania próbek analitów z ciekłego medium takie jak SPM; (semipermeable membranę), SPMD (semipermeable membranę devices), PISCES (passive in situ concentration/extraction sampler), SLM (supported liquid membranes). Szczególną uwagę zwrócono na zalety i wykorzystanie urządzenia z półprzepusz-czalnych membran SPMD.
