IMPACT OF THE JAKUŠEVEC-PRUDINEC WASTE DISPOSAL SITE ON GROUNDWATER QUALITY
Journal Title: UNKNOWN - Year 2007, Vol 19, Issue 1
Abstract
The main goal of the research shown in this paper is to investigate the cause and effect relation of the Jakuševec-Prudinec waste disposal site and the groundwater pollution. The recovery of the JakuševecPrudinec waste disposal site by the end of 2003 did not have any signifcant impact on the pollution reduction in groundwater. Very high values of the pollution index defned in the area southeastern from the waste disposal site show spreading of the pollution toward Mičevec village. The analysis of the hydrogeochemical characteristics showed that in the waste disposal site area the local geochemical anomalies of the partial CO2 pressure exist, indicating that the intensive carbonate dissolution processes and HCO3- enrichment dominate in this area. Near the border of the waste disposal site groundwater with high ammonium ion (NH4+) and chloride ion (Cl-) dominates. The high concentrations of the heavy metals and very strong geochemical bonds determined from the correlation coeffcients show that in the reductive aquifer conditions heavy metals strongly release.
