Υδροχημική αξιολόγηση της ποιότητας των υπόγειων υδάτων της υδρολογικής λεκάνης του Ασωπού ποταμού, πλησίον της βιομηχανικής ζώνης Οινοφύτων.
Translated title:
Hydrochemical evaluation of groundwater quality in Asopos river basin, near Oinofyta industrial zone.
Summary:
Groundwater contaminated with hexavalent chromium Cr(VI) is a worldwide problem of significant public health importance. In Greece, a special regulatory act (No. 100079/2015) has been enacted for the Assopos River basin, where the largest industrial zone of Central Greece is located, covering approximately 15 km² with over 200 industrial units. The rapid industrial development of the area in the 1970’s has caused extensive groundwater contamination by hexavalent chromium for decades. This study presents data collected from 7 groundwater samples during the wet season of 2021, that were analysed for major ions and hexavalent chromium. The hydrochemical analysis results show that the groundwater chemistry is dominated by Cl- in the anionic chemistry and Mg²+ and Ca²+ in the cationic chemistry, while the water types of the samples differ throughout the study area. Hexavalent chromium concentrations range from 13 to 1000μg/l. The evaluation of the highest Cr(VI) concentration has been related to industrial activity, indicating a point source of pollution, while concentrations less than 1000μg/l have been related to geogenic occurrences and assessed by international literature data.
