Opis:
We analyse the factors used for assessing groundwater intrinsic vulnerability to pollution in the mean residence time estimation method, providing a final vulnerability evaluation. The following factors were analysed: depth to shallow groundwater, effective precipitation infiltration coefficient, terrain inclination, volumetric water content of soils and rocks in the unsaturated zone and volumetric water content of the topsoil. GIS surveys were performed for two geomorphologically diverse regions: a highland piedmont and a lowland plain in Poland (Central Europe). In both cases, groundwater had spatially diverse vulnerability to contamination. The research method used relied on determining the percentage participation of the area with particular values of the parameters analysed in areas of different degrees of vulnerability. Knowledge of the extent and distribution of variability of the parameters analysed in areas of particular degrees of vulnerability helps explain the causes of spatial variation in groundwater intrinsic vulnerability to contamination in given areas.

Opis:
Groundwater is a vital resource for domestic, agricultural, industrial activities and ecosystem services. Despite its multiple purposes, the resource is under significant threat owing to increasing contamination from anthropogenic activities and climate change. Hence, in order to ensure the reliability and sustainable use of groundwater for the present and future generations, effective management of groundwater (quality and quantity) is highly important. This can be achieved by identifying areas more vulnerable to contamination and implementing protective measures. The present study aims at assessing the vulnerability of groundwater using GIS-based DRASTIC index in the Quaternary catchment (A21C) within Limpopo River Basin. The vulnerability index varied from 87 to 207. About 53.6% (408 km2) of the catchment area also exhibited high risk of groundwater contamination mostly in central, north-eastern and western part of the sub-catchment. The medium and low vulnerability classes cover only 18.1% (137.5 km2) and 21.7% (165.1 km2) of the study area, respectively. The shallow groundwater at the Doornfontein Campus belongs to very high vulnerability area. The sensitivity analysis indicates that depth to water level, recharge, aquifer media, soil and topography are the important contributors to vulnerability assessment. The correlation analysis performed to validate the final vulnerability map shows a moderate positive correlation, indicating the model’s applicability to the urbanised environment. The study indicates an area that is highly vulnerable to pollution, and hence protective measures are necessary for sustainable management of the groundwater resource in the study area. The result of this study can also be further improved and verified by using other vulnerability assessment models.

Opis:
Badania podatności wód podziemnych przeprowadzono w dolinie Wisły, na obszarze płytkiego występowania wód podziemnych. Wykonano analizę zmian stanów wód podziemnych w celu identyfikacji wartości średnich oraz wartości najniższych w wieloleciu 1999–2013. Na modelu hydrodynamicznym określono wartości zasilania infiltracyjnego odpowiadające stanom średnim w wieloleciu oraz stanom najniższym w warunkach suszy hydrogeologicznej. Przeprowadzono wariantową ocenę podatności wód podziemnych na zanieczyszczenia przy zastosowaniu metody DRASTIC, przyjmując do obliczeń średnie i najniższe stany wód podziemnych i odpowiadające im wartości zasilania infiltracyjnego. Mapy podatności dla obu wariantów podatności: podatności średniej (A) oraz w warunkach suszy hydrogeologicznej (B), przedstawiają zróżnicowanie przestrzenne występowania poszczególnych klas podatności. W wariancie A największą powierzchnię zajmuje średniowysoka i średnia klasa podatności. W okresie suszy hydrogeologicznej największą powierzchnię zajmuje średnia klasa podatności. Wyniki badań potwierdzają potrzebę wariantowej oceny podatności, szczególnie w płytkich systemach hydrogeologicznych, w których objęte są ochroną zróżnicowane ekosystemy, w tym ekosystemy zależne od wód podziemnych.
The study of groundwater vulnerability was carried out in the Vistula river valley, in the area of shallow groundwater occurrence. An analysis of groundwater level changes was preformed to identify average values and the lowest values in the period of 1999–2013. On the hydrodynamic model, infiltration rate was determined corresponding to average groundwater levels and the lowest levels representing hydrogeological drought. A variant evaluation of groundwater vulnerability to pollutions was done using the DRASTIC method, assuming the average and the lowest groundwater levels and the corresponding infiltration rates for the calculation. The vulnerability maps for both vulnerability options: medium (A) and hydrogeological drought conditions (B), show the spatial diversity of individual vulnerability classes. In Variant A, the medium and medium high classes occupy the largest area. During the hydrogeological drought the medium class is the largest area. The research results support the need for a variant susceptibility assessment, especially in shallow hydrogeological systems in which diverse ecosystems are protected, including groundwater-dependent ecosystems.

Opis:
Mining activities such as underground exploitation of hard coal deposits and open cast mining are strong factors on groundwater depending on mine life cycle phases. The impact of coal mining activities on groundwater have been reported from many countries. In this case, a vulnerability assessment was conducted base on standard DRASTIC method and its modification DRASTIC MINE (DRASTICM) method. In order to take into account, the impact of mining activities, a new parameter was added which defined the impact of coal seams on the rock mass above, including the degree of its drainage and the range of its impact. In the standard DRASTIC method, the results indicate that groundwater vulnerability with high (38.6%) and very high occurrence classes (16.9% of the area), mostly covers the central part of the cast mine. In contrast, the reclaimed area of the excavation is a low-class area. The DRASTICM method increased the vulnerability index from 3 to 24 on 95% of the area, so a new vulnerability class of extremely high was delineated, which occurred in 1.6% of the area. This indicates areas that should be treated as a priority in order to avoid pollution, and in the final stage to plan activities in the field of the reclamation of mining areas. The results showed that groundwater vulnerability assessment in coal mining areas can be significantly improved.

Opis:
The purpose of this article is to identify the main factors influencing groundwater resources and chemistry in the area of the Gdańsk agglomeration. Two groups of factors were identified: natural – including physico-geographical location, geological structure and hydrogeological conditions and also anthropogenic impact. The studied area is located within a few morphological units: Kashubian Lakeland, Coastal Terrace and Żuławy Gdańskie (Gdańsk Delta Plain). Each of the above unit is characterized by diverse geological structure and lithology of sediments, which in turn affects the diversity of hydrogeological conditions of multiaquifer formations from Pleistocene to the Upper Cretaceous. Groundwater circulation system includes so-called Gdańsk aquifer system. The main recharge area of covers the Kashubian Lakeland. The discharge zone ncludes Coastal Terrace and Żuławy Gdańskie. The aquifers are confined to varying degree which has a direct impact on the rate of contaminants migration. Anthropogenic pollutions are induced by: industry, transport, development and intensive exploitation of groundwater resources. The geogenic risks that affect aquifers in of the Gdańsk agglomeration are: salt water intrusion, brines ascent and fluoride hydrogeochemical anomaly in water from the Upper Cretaceous aquifer in Żulawy Gdańskie.

Opis:
The article presents a proposal of the classification of hydrogeological and environmental conditions in relation to different intensities of the impact of factors affecting groundwater threat in assessments of groundwater vulnerability to pollution. Due to the complexity and high degree of transformation of the natural environment, including aquatic, types of areas subjected to ordinary and strong anthropopressure, the so-called Area Geotypes (GO), are distinguished and discussed. The main factors characterizing the impact of mining activity on the water environment (typical and specific) are discussed, and the mine ’s characteristics are highlighted, emphasizing its role and importance as an influator constituting a large, multifactorial source threatening the groundwater environment. The role of the mine as an influator is presented against the background of the mine ’s "life cycle”(development phases) along with an indication of the desirability of carrying out assessments of groundwater vulnerability to pollution and groundwater threat assessments. The need to develop legal regulations regarding the preparation of vulnerability assessments is indicated.

Opis:
Groundwater vulnerability assessment is an important environment management tool. In this study assessment of groundwater vulnerability to pollution was conducted by DRASTIC method in urban area, represented by the Bielany - district of Warsaw. The results of this study showed that 70% of the study area has medium or moderately high pollution potential and nearly 30% area has low and very low pollution potential. Two sensitivity tests were performed: the map removal sensitivity analysis and the single-parameter sensitivity analysis. Sensitivity analysis is defined as the evaluation of the effect of changes of input values on the output of the model, therefore, in order to reduce subjectivity of groundwater vulnerability assessment sensitivity analysis was performed for DRASTIC procedure. Both tests highlighted the role of the parameter „depth to water" in groundwater vulnerability assessment.

Opis:
W artykule przedstawiono ocenę jakości i podatności na zanieczyszczenia wód pierwszego poziomu wodonośnego (PPW) w rejonie doliny rzeki Nidy na odcinku Brzegi–Pińczów. Klasy wrażliwości wód PPW na zanieczyszczenia, określone stopniem podatności naturalnej, oceniono na podstawie czasu wymiany polowej pojemności wodnej gleb i skał strefy aeracji przez infiltrujące wody opadowe (MRT – mean residence time). W badanym rejonie występują głównie wody o bardzo wysokiej i wysokiej klasie wrażliwości. Na podstawie oznaczeń polowych wybranych wskaźników jakości wód wyznaczono pięć stref, gdzie PPW jest zanieczyszczony związkami azotu (NO3 >50 mg/dm3) oraz sześć rejonów zagrożonych zanieczyszczeniem (25 < NO3 > 50 mg/dm3). Zanieczyszczenia mają charakter lokalny i pochodzą z obszarów zwartej zabudowy nieobjętej kanalizacją sanitarną lub powstają w rezultacie rolniczego użytkowania terenu. Migracji związków azotu sprzyja brak naturalnej izolacji na większości badanego obszaru. Ze względu na realne zagrożenie zanieczyszczeniem azotanami wód PPW niezbędne jest wnikliwe monitorowanie zmian zawartości azotanów w wodach podziemnych.
This article presents estimation of water quality and susceptibility of shallow water table aquifer to pollution in the Brzegi–Pińczów section of the Nida River valley. Groundwater vulnerability is evaluated according to mean residence time (MRT) determined by the time of water infiltration from the ground surface to the groundwater table of the first aquifer according to the piston flow model of soil water and unsaturated zone water. The analysis shows that the groundwater vulnerability is mainly very high and high in the study area. This means that the aquifer is susceptible to penetration of pollution from the surface. On account of the risk of nitrogen contamination to the first aquifer waters, it is necessary to monitor nitrogen content changes in groundwater.

Opis:
Mapy podatności naturalnej wód podziemnych na zanieczyszczenia stanowią wizualizację oceny podatności wód podziemnych na zanieczyszczenia. Są one jednym z najważniejszych elementów uwzględnianych przy podejmowaniu decyzji odnośnie zagospodarowania terenu i obiektów potencjalnie uciążliwych dla środowiska. Badania podatności wód podziemnych na zanieczyszczenia zostały przeprowadzone na obszarze Kampinoskiego Parku Narodowego (skala regionalna) oraz na wytypowanym poligonie w pobliżu Wiktorowa w Kampinoskim Parku Narodowym (około 30 km2) w skali lokalnej. Ocenę podatności naturalnej przeprowadzono przy zastosowaniu zmodyfikowanej metody DRASTIC oraz na podstawie szacunku czasu przesączania się zanieczyszczeń konserwatywnych. Uzyskane rezultaty wskazują, że rezultat oceny zależy od wykorzystanej metody, stopnia rozpoznania warunków hydrogeologicznych, zastosowanych uproszczeń oraz wyznaczonego celu badań.
Maps of natural groundwater vulnerability to contamination illustrate the assessment of natural groundwater vulnerability. They are also one of the important components that are taken into consideration while making a decision as regards the site management and objects potentially troublesome for the environment. The researches of natural vulnerability were conducted for the area of the Kampinoski National Park (on a regional scale) and for the area (about 30 km2) near Wiktorów (part of the Kampinos National Park) on a local scale. The assessment of vulnerability has been performed with the use of the modified DRASTIC method and calculations of the time migration method of a contaminant through the unsaturated zone. The results of the study indicate that the evaluation of natural groundwater vulnerability to contamination depends on the following factors: research methodology, degree of area recognition, applied simplifications and the purpose of research.

Opis:
Groundwater is a very important natural resource to support the activities of the residents of Pakis District, Malang Regency. On the other hand, increased activity puts pressure on groundwater quality. Agricultural intensification, urbanisation, and industrialisation can be sources of pollutants. Hydrological factors, topography, lithology, and surrounding rainfall are triggers for contamination of groundwater. The main objective of this research is to determine the characteristics, quality of groundwater, and its susceptibility to pollution. To complete this research, geoelectric measurements were carried out at 43 points spread throughout the study area and sampling of 18 shallow wells in agricultural, residential, and industrial areas for chemical analysis. All data obtained were analysed to create a map of the spatial distribution of groundwater vulnerability. The results show that the groundwater in the study location is in the transition zone and flows through the volcanic rock layers. The level of groundwater pollution is in the uncontaminated status to heavily polluted with pollutants in the form of heavy metal manganese and Escherichia coli bacteria. The spatial distribution of groundwater intrinsic vulnerability shows low, moderate, and high levels of vulnerability, respectively 32.99%, 60.87%, and 6.14% of the research area. Groundwater specific vulnerability associated with land use factors shows that 26.25% are negligible, 42.46% are low, and 31.29% are moderate. From this it can be concluded that the study area has been polluted both geogenically and anthropogenically, therefore, special actions must be taken to restore the quality of groundwater.

Opis:
Groundwater is a vital resource for domestic, agricultural, and industrial activities, as well as for ecosystem services. Despite this, the resource is under significant threat, due to increasing contamination from anthropogenic activities. Therefore, to ensure its reliability for present and future use, effective management of groundwater is important not only in terms of quantity (i.e. abstraction) but also quality. This can be achieved by identifying areas that are more vulnerable to contamination and by implementing protective measures. To identify the risk and delineate areas that are more exposed to pollution, various groundwater vulnerability assessment techniques have been developed across the globe. This paper presents an overview of some of the commonly used groundwater vulnerability assessment models in terms of their unique features and their application. Special emphasis is placed on statistical methods and overlay-index techniques. The assessment of the literature shows that statistical methods are limited in application to the assessment of groundwater vulnerability to pollution because they rely heavily on the availability of sufficient and quality data. However, in areas where extensive monitoring data are available, these methods estimate groundwater vulnerability more realistically in quantitative terms. Many works of research indicate that index-overlay methods are used extensively and frequently in groundwater vulnerability assessments. Due to the qualitative nature of these models, however, they are still subject to modification. This study offers an overview of a selection of relevant groundwater vulnerability assessment techniques under a specific set of hydro-climatic and hydrogeological conditions.

Opis:
The assessment of groundwater vulnerability is a crucial part of planning and water management because it can identify areas where aquifers are more susceptible to contamination. Depending on the vulnerability assessment method, the results can differ significantly. Consequently, different methods can provide ambiguous information that could further influence decision-making processes in planning or water management. For the Pliszka River catchment, the intrinsic groundwater vulnerability of the uppermost aquifer was estimated using four different methods: DRASTIC, GOD, and two methods that are based on empirical formulas of water residence time in an unsaturated zone. The input data include a series of thematic maps supplemented by 1,322 shallow borehole profiles and laboratory tests of samples collected in the course of fieldwork. The collected data were processed in GIS software, and the results of each method were mapped in high resolution. The resulting maps of groundwater vulnerability were then quantitatively compared to validate their applicability for the assessment of groundwater vulnerability in a typical North European Lowland river catchment. The maps generated by the DRASTIC and GOD methods are dominated by areas with moderately high (54.6 and 48.4%, respectively) and moderate groundwater vulnerability (32.7 and 32.3%, respectively). No areas of high groundwater vulnerability are present. One of the water residence time methods provides results similar to the previous methods at the catchment scale, and one method yields high groundwater vulnerability values for the majority of area.

Increasing urbanization, economic development and agricultural activities, combined with limited precipitation contribute to the quantitative and qualitative degradation of groundwater resources, especially in the eastern Mediterranean region. For this purpose, a series of actions are implemented including groundwater vulnerability mapping that can depict prone to pollution aquifers which need protection and/or restoration measures. In this study, the efficiency of two well-known methodologies (COP and DRASTIC) for groundwater vulnerability and pollution risk mapping was assessed in the Sperchios river basin. The vulnerability and pollution risk maps of the two methodologies were spatially compared to each other and the observed similarities and differences were discussed and explained. The output of the study shows that in the particular geoenvironmental conditions DRASTIC method performs better than the COP, particularly in the lowland, porous media aquifer.
