One of the important tasks of state policy is to protect groundwater against quantitative and qualitative degradation. Estimation of costs of establishing protection areas of MGBs is of crucial meaning taking into account the balance between the costs of prohibitions and restrictions and the benefits related to the value of protected groundwater resources. The costs have been evaluated on the basis of a legal opinion, where the key components are major prohibitions that take into account the assumptions of the Water Law, the Environmental Protection Act, and the Local Spatial Development Plans. The analysis was based on two MGBs located in the Central Odra region, characterized by different sizes, hydrogeological conditions and development, both of Quaternary age. The land cover and the development of the area are keyfactors influencing potential compensations and conflicts. The final results of the calculations with accuracy to the municipality have shown a strong dominance of the benefits of the existence and protection of both MGBs over the possible costs.

The paper presents the methodology of estimating costs related to the legal establishment of MGB protection areas designated in hydrogeological documentations. The methodology outlines the actions allowing for carrying out balance sheets of costs arising from the introduction of rules, prohibitions and restrictions on land or water use in protected areas, compiled with the benefits of current and potential use of groundwater and preservation of current water quality. Implementation of the methodology is intended to help in the rational evaluation of the correctness of establishing protected areas. Pilot calculations were made for MGB No. 138 Pradolina Toruń-Eberswalde. The costs and benefits were estimated at the amount of 31.6 million PLN and 483.2 million PLN, respectively. Finally, the legal basis for the establishment ofprotection areas for this groundwater basin was addressed positively.

From 2009 till 2016 one of the largest in the recent years hydrogeological project "Making programmes and geological documentation in order to specify hydrogeological conditions due to determining protection zone of Main Groundwater Basins (MGB)" has been led by Polish Geological Institute - National Research Institute. The aim of the project was to document and describe MGBs as the most valuable and strategic groundwater reservoirs in Poland. Therefore set of documents for 101 MGBs and adaptation of 30 already existing pieces of MGBs documentation made before 2008 has been done. 131 documented MGBs encompass around 87 000 km2, which is 26.8% area of Poland. 20 groundwater basins didn’t meet all for MGB s established hydrogeological parameters, so they were reclassified to Local Groundwater Basins (LGB). 19 of all groundwater basins (15 MGBs and 4 LGBs) don’t need protection zones as the natural thickness of confining bed provides sufficient protection. For 112 of groundwater basins the protection zone has been determined. Their surface covers around 48 500 km2, which encompasses 15.5% area of Poland.

In case of groundwater intakes with a low well discharge, localized in simple hydrogeological conditions, the wellhead protection area (WHPA) can be delineated by one of available analytical methods. The differences between the WHPA ranges delineated by analytical methods, give rise to the question which method would be optimal to be used to handle simple hydrogeological conditions. Analytical methods considered in the study include the Wyssling method, the Krijgsman and Lobo-Ferreira (K&L-F) method, and the Analytical Element Method (AEM). WHPA delineated using analytical methods are compared with data obtained from hydrogeological numerical model, which becomes the reference method. The study was performed for two single wells, and a simplified case was considered too, whereby two wells were represented by an equivalent one. The criterion used in the assessment is the distance upstream from the well to the zone boundary (Lu ), for various time-of-travel to the intake (1, 2, 3, 4, 5, 10, 15, 20, 25 years), and the shape and lateral extent of the WHPA. Discrepancies between the analytical methods vary depending on the time-of-travel, reaching 11% at most. Discrepancies between the analytical methods and numerical modelling results for single wells vary depending on the time-of-travel and the employed analytical approach, reaching 25% at most. For time-of-travel longer than 5 years, the maximal distances Lu calculated by the analytical methods are found to be smaller than those obtained by the reference method. The study indicate that results obtained by compared analytical methods are rather similar each other, but not similar to numerical modelling data. For scenario with the equivalent well there is major discrepancy between the reference values and analytical data.

Występujące zagrożenia mają różny charakter, ale najczęściej są związane z obszarem, którego dotyczą. Niezależnie od rodzaju zagrożenia czy ze strony środowiska przyrodniczego, czy spowodowanego działalnością człowieka powodują one destrukcje czasami na znacznych przestrzeniach. N ierzadko wymuszają konieczność poniesienia bardzo dużych nakładów finansowych dla przywrócenia poprzedniego stanu zagospodarowania, czasami jest to zupełnie niemożliwe. W procesie planowania przestrzennego niektóre obszary zagrożeń są wyartykułowane, np. związane z powodzią. Istnieje jednak także pewna ilość obszarów, które stale lub periodycznie podlegają rozmaitym zagrożeniom i w tym zakresie nie są podejmowane znaczące działania na rzecz ich ograniczenia lub wyeliminowania. Wydaje się więc, że konieczne jest wyodrębnienie tych terenów i podjęcie próby określenia aktywności możliwych do realizacji w tych obszarach, podobnie jak dla terenów, w których chronimy wartości ich przestrzeni.

Occurring hazards are diverse, but most are associated with the area concerned. Regardless of the type of hazard, from the natural environment, whether caused by human activity are causing the destruction of the sometimes considerable areas, often forcing the need to incur very large amounts of money to restore the previous state land, or causing, it is sometimes quite impossible. In the process of planning, some areas are articulated dangers such flooding. T here are also a number of areas that are permanently or periodically subject to various risks. In this respect are not taken significant action to reduce or eliminate these risks. It seems that there is an urgent need to identify these areas and to attempt to identify possible activities to be implemented in these areasas it exists for the areas in which we protect the value of their space.
