Treatment train remediation of hydrocarbon contaminated groundwater in Ireland
We were commissioned by Nova Consulting to assist them in the remediation of a plume of hydrocarbon impacted groundwater that had migrated from a nearby fuel station and impacted the local drinking water supply. The contaminated water was 5m below ground level in jointed limestone. Geoenvironmental’s initial task was to develop the remediation strategy and gain agreement from the local authority. The strategy included:
- Free product recovery
- Dissolved phase treatment by pump and treat
- Residual contamination treatment by chemical oxidation
- Sampling and analysis of groundwater to demonstrate that natural attenuation was occurring
