Insulating company with phenol and oil contamination Spills of non-polymerisated phenolicformaldehyde resulted in the phenol pollution of groundwater. The area around the storage tanks was contaminated with diesel fuel and heating oil.

Project description

Client: Insulating company with phenol and oil contamination

Technology:
Soil bioremediation in-situ with bioaugmentation, nutrient addition through injection wells
infiltration galleries, active soil aeration system
groundwater pump and treat system, with activated carbon adsorption

Project Status: Completed

Media (quantity in m³):
Soil (in-situ): 3000m³ Groundwater: 3000m³

Contaminants:
diesel, heating, and lubrication oil, phenol

Project Manager: József Varga, Judit Tóth

Date of operation: 1994-1996

Cleanup goals (=contaminant concentration after treatment)
Residual petrol hydrocarbons in soil: 500 ppm, in groundwater <0.1 mg/l
Phenol in groundwater 0.05 mg/l

Contaminant concentration before treatment:
petrol hydrocarbon contaminated soil treating in-situ 500-5000 ppm
in groundwater dissolved diesel hydrocarbon 1-3 mg/l, phenol 0.5-2 mg/l
