  PROJECT DESCRIPTION


The site was a garage for public transport buses with refueling and maintenance facilities. Extensive subsurface contamination was detected, mainly in the vicinity of fuel handling points. The diesel oil contamination was concentrated above the saturated zone.

Technology
Soil excavation and in-situ bioremediation with bioaugmentation, groundwater pumping and skimming.

Project Status: Completed

Media (quantity in m³):
Soil (ex-situ): 1,500
Soil (in-situ): 10,500
Groundwater: 3,000

Contaminants: Diesel oil, lubrication oil

Client: Budapest Public Transport Company

Project Manager: József Varga, Judit Tóth

Completed Project Information
Date of Operation: 1995-1999 Cleanup Goals: Residual contaminant in soil <1,000 ppm, in groundwater <0.1 mg/l

Contaminant concentration before treatment:
Excavated soil ranged from 10,000 ppm to 25,000 ppm,
in-situ treated diesel and lubrication oil contamination in soil 1000-15000 ppm
in groundwater free phase in film, dissolved contamination 1-5 mg/l.

Contaminant concentration after treatment: less than cleanup goal.

Contamination of a state railway brakeyard

The main source of contamination was a fuel spill that occurred in 1995. The breakage of an underground pipeline resulted the release of approximately 80 m³ diesel oil.( Index )

Contamination of former Soviet Military Installation fuel base

A site of  200 above-ground storage tanks was contaminated with diesel fuel and lubricants. A volume of 50 m³ of subsurface soil and groundwater was contaminated by gasoline.( next chapter --> )
