The article presents the usage of electrical resistivity imaging (ERI) in ground recognition for linear constructions such as the Warsaw Southern Ring-Road. Measurements were performed in a gradient array, on five segments of the route, with previously researched geological conditions. Measurement method intended to probe the soil matrix on different depths. Therefore, the electrode array was set to 2 to 5 meters. The resulting image of resistivity differed in resolution. Resistivity images were correlated with geological data from boreholes in geology-engineering documentation and other widely available geological information from databases and literature. This allowed to limit ambiguity of interpretation of two-dimensional model of near surface soil matrix resistivity. Thereby, individual ranges of resistivity were assigned to geological content. The measurements allowed to identify geological horizontal variability. Electrical resistivity imaging research confirmed its utility in the recognition of spatial distribution of geological media in foundation soil. The analysis of completed surveys allowed to designate the following areas: locations where anthropogenic and organic soils occur, probable location of the edge of the upland on the eastern side of Vistula River and upper relief of local Neogene clays.

The article presents the attempt to systematize the problems of urban geology using the example of Warsaw agglomeration. The introduction discusses the available literature, both domestic and foreign. It was noted that many authors understand this concept in various ways, defining it differently. This is the result of diverse interests of researchers, whose common point is that their works and research were located in or associated with urban areas. It also presents, in general, the range of subjects and the set of tools related to Earth sciences, which help in solving research tasks. The article makes reference to the constraints associated with availability of the land and problems related to the applicability of methods. It presents the thesis stating that the needs of users of geoinformation in the urban environment are different from the current ones, which were mainly focused on natural resources, rather than on interaction or coexistence of natural resources and development. The recipients of geoinformation in the urban environment, in relation to the presented conceptual scheme, are mainly people or institutions that do not have an appropriate knowledge of geology. Hence, it is necessary to present geoinformation in a clear and accessible manner, as conclusions or guidelines for use. The examples presented in the article prove that geology of urban areas is now becoming a very important part of knowledge necessary for proper, sustainable development of our cities. Over the last few years a significant part of the population moved to urban areas. This trend is noticeable in Poland and around the world.

Przedstawiono tok postępowania w pracach rekultywacyjnych gleb i gruntów zdegradowanych chemicznie. Na podstawie uzyskanych danych z poligonu badawczego w Łomiankach wykazano konieczność dokonywania badań geochemicznych na terenach, gdzie istnieje chociażby niewielkie prawdopodobieństwo skażeń, określając metodykę badań, kryteria ocen i przykład rekultywacji. Sposób realizacji inwestycji uzależniono od szczegółowego rozpoznania stopnia degradacji podłoża i jego zasięgu przestrzennego w nawiązaniu do wykształcenia litologicznego warstw, warunków geologicznych i hydrogeologicznych oraz koncepcji rekultywacji.

The article presents the course of action in reclamation works on chemical degradation of soils and grounds. On the basis of the data gathered from the test site, the need for geochemical analyses has been demonstrated in the areas of even a slight possibility of contamination. The methods of analyses, evaluation criteria, and example of reclamation have been specified. The way of executing the investment will depend on the detailed identification of the degree of the substrate degradation as well as its spatial extent in relation to the lithologic formation of layers, geological and hydrogeological conditions and the resulting concept of recultivation.

The article presents some of the problems related to the practice of documenting anthropogenic soils, focusing primarily on linear investments such as roads. It discusses the rank of anthropogenic soils in soils classification as in PN-86/B-02480: Building soils. Definition, symbols, and description of the soils classification and it elaborates on the difficulties in distinguishing anthropogenic from indigenous soils. Using the example, inter alia, of Trasa Armii Krajowej in Warsaw, the Authors present problems associated with construction on anthropogenic soils, including those soils with great thickness, and illustrate problems with assessment of the condition of old berms, predominantly consisting of ashes. In addition, the article demonstrates that the study of anthropogenic soil construction should be comprehensive and should entail indigenous soils in the immediate vicinity of the site.

A case study of 18th-century Saint Andrew church in Brwilno Górne near Płock is presented to illustrate the problems of protecting historical monuments located in areas subject to especially active geodynamic transformations. The church has been built on upland near Vistula River valley escarpment. The wooden church could not be relocated because it is listed in the register of historic monuments together with its surroundings. Thus, extensive geological studies were performed and the recommended precautions against disaster were formulated. Two variants of securing the church were proposed: provisional and final.
