Hungarian state railway: Remediation of a wood preserving facilityThe storage and handling of treated timber and the runoff of chemical preservatives (oil, oil tar, chromated copper salt) gave rise to soil and groundwater contamination.
|
| City: | Püspökladány |
| Site Description | More than one hundred years of wood preserving activity had taken place at the site. The storage, handling, deponing and runoff of chemical preservatives (mixed oil and oil tar, chromated copper salt, phenols) used in timber treatment has resulted in soil and groundwater contamination. |
| Site Type | Wood Preserving |
| Technology: | 
Soil excavation. Subsurface slurry wall construction 1200 meters.Construction and operation of a 400 meter long drainage system for groundwater abstraction. Cleaning device: oil separator, air stripping unit and blower, activated carbon adsorber, selective ion exchange separator for copper, reductive fixation for CrVI |
| Project Status | Work in progress |
| Media Quantity (m³) | Soil (ex-situ) 3000m³, Groundwater 7000m³ |
| Contaminants | PAHs, phenol, creosote, heavy metals |
| Client | Hungarian State Railway / Wood Treating |
| Project Manager | József Varga, Árpád Lorberer |
| Project Information | Date of Operation: 1998- |
| Contaminant concentration before treatment: |
In soil TPH 3000-5000 ppm, Phenol 500-1000 ppm In groundwater dissolved TPH 5-20 mg/l, BTEX 1-5 mg/l Phenol 3-5 mg/l |
| Cleanup objectives: | TPH in soil: 1000 ppm. In groundwater: phenol 0.05 mg/l, BTEX 0.15 mg/l |
