Item type:Article, Access status: Open Access , The modified Dräger probe to the geochemical research of the soil gases composition(2015) Fąfara, Zbigniew; Ilkiv, Igor; Solecki, TadeuszThe Dräger probe in the measurement set to the geochemical research of the soil gases composition is inconvenient to use. It's heavy, which are reąuired to operate at least two people. Cumbersome and time-consuming is to place it into the soil by impact method, and often there is fail to reach the planned measurement depth. For this reason, there was designed and made the new modified Dräger probe. The new probe has significantly lower mass and outer diameter. In principle it should be possible to introduce it into the soil by pushing, which will greatly facilitate and accelerate conducting the geochemical research of the soil gases composition.In the autumn of 2014 has been tested the modified Drager probe. The purpose of this study is to assess it suitability to conduct the geochemical research of the soil gases composition. In total there were performed 374 measurements of the soil gases composition at different depths in the 247 measurement points. In 99 cases (26.5%) there was failed to perform the measurement because the soil gases flow rate through the meter was too little. Pulling probe usually allowed to perform the research - in only 6 measurement points (2.4%), it was impossible. The average depth of the measurement point is equal to 0.78 m.Item type:Article, Access status: Open Access , Threats to the environment in the areas of abandoned extraction of hydrocarbon deposits(2015) Rybicki, Czesław; Solecki, Tadeusz; Winid, BogumiłaThe environmental problems in past mining areas, where the production process was ended, are connected with contaminations coming from past extraction processes and the risks relating to the abandonment of wells and deposits. The risk could be variable depending on such factors as the geological formation and hydrogeological conditions in the analyzed area, and the condition of abandoned wells. The main source of contamination could be improperly sealed abandoned wells and unplugged abandoned oil and gas wells. The environmental problems could be particularly concern on the area of old historical extraction sites. There are some hydrocarbon deposits, where production i s endedand still it is possible to see places of wells and remains of an old oilfield infrastructure. Unplugged or improperly sealed wells can result in stray gas migration or contamination of soil, ground and surface and ground waters. The end of well exploitation may cause the risk associated to the restoration of formation pressure. This could be the reason of uncontrolled discharge of gaseous and liquid hydrocarbons into shallow depths. Returning to the extraction from some deposits could reduce the formation pressure and constrain uncontrollable leakages of hydrocarbons. This option seems to be environmentally friendly. Authors of the paper made efforts to evaluate the scale and the range of mentioned disadvantageous phenomena.Item type:Article, Access status: Open Access , Monitoring of petroleum substances in the neighborhood of drinking water intake(2016) Solecki, TadeuszThis article concerns the monitoring of underground water quality in the vicinity of underground water intake, which is carried out continuously (quarterly) in six monitoring wells situated near the water intake. Groundwater occurring in this complex form a continuous and prosperous aquifer exploited with deep- water wells 19A and 19', intended to supply the population of part of Kraków with drinking and industrial water. Operated monitoring wells and holes are set in Czyżyny district in the protection zone of undergro- und water intakes Mistrzejowice. During the field research it were carried 41 quarterly measurements of petroleum substances at ground- water table. These tests were carried out using specialized equipment of Dutch company Eijkelkamp Agri- search Equipment, which can measure thickness of petroleum substances at groundwater table in each monitoring well. During the laboratory studies 41 quarterly measurements were performed. Determination and quantitative analysis of petroleum substances in groundwater samples were made. For laboratory testing methodology Fourier infrared spectroscopy was used. Laboratory studies of oil products in water samples showed the variable contents in each series. The statistical analysis was also done using Shewhart’ s control card.Item type:Article, Access status: Open Access , Petroleum substances in soil and groundwater in the urban areas(2016) Solecki, Tadeusz; Stopa, JerzyThe result of human activity is polluting the soil and water. Based on the results of heavy metals studies it can be stated that the level of contamination of soil and water in urban areas is not high. This image is changing after taking into account other types of pollution. Besides some heavy metal contamination urban areas are contaminated with petroleum. Contamination of oil derivatives has a significant impact on the soil and water environment. In addition, some petroleum substances, such as petrol, have high vapour pressure. This causes a displacement of soil air from the vadose zone through the hydrocarbon gases, which creates a risk of explosion, especially in urban areas. This paper describes the pollution of ground-water oil derivatives in an urban area on the example of an oil filling station, operated for several years. In order to assess the condition of soil, 90 soil samples from different depths and 20 samples of groundwater were taken. Samples were taken for laboratory oil content tests. Using a computer program, a map of quality standards exceedances of soil and groundwater at the oil filling station and its vicinity was created. Results of laboratory tests of water samples are presented in tables and based on them, the classification of the underground water quality was made. Results of this study indicate a significant pollution of soil and groundwater exceeding the applicable standards. Condition of the soil and the quality of underground water in the oil filling station indicate the necessity of reparation.
