In 2021 OCM was involved in the assessment and remediation of soil and groundwater contamination at IE licensed sites in Leinster and Munster.
At a facility in Munster the assessment included weekly monitoring of contaminants of concern in the groundwater, preparation of a Detailed Quantitative Risk Assessment and the development of a Remedial Strategy which was reviewed and approved by EPA. Remedial works included installation of a groundwater well to pump and remove contamination from the groundwater.
At a facility in Leinster OCM completed a Tier III Risk Assessment and developed remedial works programme which was reviewed and approved by EPA. The remedial works included the excavation and removal of contaminated soils and in situ treatment of residual soil and groundwater contamination using a chemical oxidant. Subsequent groundwater monitoring confirmed the remedial works has been effective at removing contamination and mitigating the risk to off-site receptors.
At a facility in Munster OCM completed a Tier III site investigation of soils and groundwater to delineate a contamination plume. A remedial works programme involving a substantial drainage upgrade was completed. OCM designed a groundwater monitoring network to assess improvements in groundwater quality.
OCM completed an assessment of an oil spill at a retail store in County Kerry. The assessment included the identification of the source of the leak, an investigation to establish the extent of contamination, the removal of contaminated soils and the design and installation of a pump and treat system to remove contaminated groundwater.
