    Opis:
    The paper presents the results of research on variability of basic physical and chemical parameters of peats from a small fen in the Struga Wodna valley on the Lubartów Plateau. The variability of organic matter content, moisture content, pH and cation exchange capacity (CEC) was analysed. Apart from descriptive statistics, geostatistical methods were also used, including the analysis of semivariograms. All determined parameters showed high variability, including spatial variability. The analysis of the semivariograms showed that for each of the parameters there is a nugget effect, indicating high local variability. The statistically highest variability, expressed by the coefficient of variation, was shown by peat moisture content,while the moisture content showed the highest spatial autocorrelation. The use of geostatistical methods allowed identifying zones with different properties within thefen, and describing the spatial autocorrelation of individual parameters.

    Opis:
    An anal y sis of cat ion-ex change ca pac ity (CEC) vari abil ity of peats is pre sented in ver ti cal pro files from east ern and cen tral Po land. CEC val ues were com pared with ash con tent (Ac), pH and CaCO3 con tent. Eight peatlands were selected for re search in the fol low ing ar eas: War saw Pla teau (2 ob jects), Siedlce Pla teau (2 ob jects), Lubartów Pla teau (2 ob jects), Na³êczów Ta ble land (1 ob ject) and Dobrohusk De pres sion (1 ob ject). The peatlands rep re sented a fen peat type of sim i lar bo tanic com po si tions of sed i ments, but they dif fered in the area, peat thick ness and drain age con ditions. Char ac ter is tic reg u lar i ties in CEC vari abil ity were noted in the peatlands and there were three types of CEC vari abil ity in ver ti cal pro files. Car bon ate peats (types 1 and 2) had the high est pH and def i nitely the high est val ues of CEC. In ver ti cal pro files, there was also a zonation, but the reg u lar i ties sim i lar to non-car bon ate peats were not observed. Dif fer ent dis tri bu tion of phys i cal and chem i cal pa ram e ters were es tab lished in ver ti cal pro files in partly drained peatlands (with a muck layer on top) with non-car bon ate peats (type 3) and there were three dis tinct zones in ver tical pro files, with dif fer ent Ac and CEC. De ter mi na tion of the ver ti cal CEC vari abil ity and other phys i cal and chem i calpa ram e ters in peatlands made it pos si ble to dis tin guish zones with po ten tially most ben e fi cial iso la tion con di tions.

    Opis:
    Engineering activity may lead to uncontrolled changes in the geological environment. This paper presents an example of structural changes in fluvial sand of the Praski terrace (in Warsaw) caused by the activity of a temporary concrete batching plant. Our investigations made it possible to identify the material responsible for the structural anomalies observed in the bottom of the trench excavation. The compound responsible for the cementation phenomenon was identified as ettringite – hydrated calcium aluminosulphate: Ca6Al2[(OH)12(SO4)3]·26H2O. The source of ettringite were most probably significant volumes of contaminants coming from the temporary concrete batching plant (e.g., from the rinsing of concrete mixers and/or installations for concrete storage and transportation). While penetrating into the ground, ettringite caused extensive cementation of the soil mass, mainly in the saturation zone. As a result, the mineral (chemical) composition of the inter-grain space changed and the structure of the sand was strengthened. The estimated zone of volumetric changes in soil properties was about 6 thousand m3. However, analysis of the chemical composition of groundwater for its potential sulphate contamination, did not reveal any anomalous concentrations of sulphates.
