Megaterra Ltd. made an expert report concerning the formerly revealed soil and groundwater contamination originated from hydrocarbon in an industrial property in the city of Hajdúnánás focusing on the contamination source and origin as well as responsibilities, liabilities, risks and further measurements. Hydrocarbon contamination was also found by our investigations due to former activities (storage…
Landfill gas monitoring wells were installed and accredited on-site and laboratory analysis were carried out on a revegetated municipal landfill site.
Alyphatic and chlorinated alyphatic hydrocarbons were measured in the groundwater above the action level in a site of a machinary manufacturer company, Orosháza. Groundwater was contaminated vertically down to the first clay layer. Remediation is going on using pump and treat, stripping and filtering and bioremediation.
Supplementary environmental assessment was carried out in the “Rózsás” farm near the village Kismarja, including the evaluation of the available geology, soil and groundwater contamination data, drilling soil boring, soil and groundwater samplin and on-site and laboratory analysis. Hydrocarbon contamination was found in the soil and groundwater above the action level as a possible result…
In order to characterize the effects of red mud catastrophy accredited soil sampling and analysis were carried out in the vicinity of Kolontár and Devecser villages.
95 soil drillings were made, soil and ground water samples were taken and analysed for TPH and heavy metals in order to delineate contaminated soil and ground water of an illegal sewage disposal site having several reservoirs. We have found that the South-East part of the property is only lightly contaminated not requiring any remediation…
Landfill gas ingredients and gas compound static and dynamic concentrations were measured on 5 landfill sites before revegetation using installed gas monitoring wells. Providing 8 hour long continous pumping with 34-71 L/min gas analysis in each hour was carried out. Based on the analytical data we classified the landfill sites into 3 categories: I. Landfills…
37 drillings were made (8 m deep each), soil and ground water samples were taken and analysed on-site and in the laboratory in order to detect and delineate contamination of an abandoned railway station. We drilled manually two bore holes in the parking place of the trains under the basalt stone bed and took soil…
20 bore holes were made (6 m deep each), soil and ground water samples were taken and analysed on-site and in the laboratory. We stated that soil of the studied area is contaminated by TPH and other alkyl benzols above contamination level (“B” value). Surface projection of TPH contamination above “B” value is 408 m2,…
17 bore holes were drilled, soil and ground water samples were taken and analysed on-site and in the laboratory. Ground water of the studied property is contaminated by TPH and PAH above contamination level (“B” value). Surface projection of the ground water contaminated by TPH above “B” value is 980 m2, above remediation level (“D”…
