Abstract
The analysis of groundwater contamination at the former military airport, due to fuel tanks leakage and other accidental spills, mainly involving polycyclic aromatic hydrocarbons (PAH), is presented in the paper. It was observed by modelling that, after termination of pumping, the contaminant by-passes the slurry wall around its edges and proceeds towards the withdrawal area. The modelling showed that the water contamination hazard is quite low, which is mainly due to pollutant deterioration (decay) and sorption. Systematic and long-term groundwater quality monitoring is recommended once pumping at the barrier is stopped.
Rad se bavi analizom onečiščenja podzemnih voda na području bivšeg vojnog aerodroma uzrokovanog curenjem goriva iz spremnika te drugim slučajnimi izlijevnjemonečiščivača, uglavnom policikličkih arometskih ugljikovodika (PAH). Modeliranjem je zamiječeno da nakon prestanka crpljenja zagadivač zaobilazi brtveni zid oko njegovih rubova te se natavlja kretati prema području gdje se zahvača voda. Ovim modelom zaključeno je da postoji niska razina opasnosti od zagadenja, uglavnom zbog utjecaja raspada (razhradnje) zagadivača te sorpcije. Preporučeno je dugoročno i sustavno pračenje kvalitete podzemnih voda nakon prestanka crpljenja vode.
