Abstract:

Old environmental burdens, such as the area of Airport Sliač-South, are a source of multiple contaminants which are able to transfer to the surrounded environment and, therefore, pose a serious risk for the environment itself and human health. Among the group of contaminants polyaromatic hydrocarbons (PAHs) are also classify and determined in the groundwater within the after-remediation monitoring from 2015 to 2020. In total, 7 sampling spots were chosen at the southern area of the airport. Groundwater samples were taken twice a year into prepared sample boxes. The samples were delivered to the State Geological Institute of Dionýz Štúr laboratory in Spišská Nová Ves within 24 hours after collection Major part of PAHs in all the samples and throughout the period of measurements was represented mostly by naphthalene. The relationship between the concentrations of PAHs and TOC as well as between the concentrations of PAHs and NES was studied. Positive correlation was proved in the relationship between the concentration of PAHs and NES. The result of the after-remediation monitoring of studied locality results into the conclusion that the extent of pollution is decreasing. Concentrations of NES and TOC exceeding the limits (Directive of the Ministry of the Environment SR 1 / 2015-7 for risk analysis) can be still found in the samples of groundwater from the bores within the source locality of environmental burden. Up to 2016, the concentrations of PAHs were exceeding the limits as well. Generally cited guidelines indicate that the groundwater samples manifest poor quality of the groundwater and refer to the importance of after-remediation monitoring of sanitized environmental burdens.
