Phase II Gilby Gas Plant

Focus was retained to delineate the aerial extent of on- and off-site light non-aqueous phase liquid (LNAPL) impacts to soil and groundwater and to complete a monitoring and remedial action plan for a former gas plant facility in Central Alberta. This plan was a requirement of the facility’s Approval to Operate, which is issued under the Alberta Environmental Protection and Enhancement Act.

This facility had multiple sources of contamination and complex geology (glacial till and bedrock) and hydrogeology. In addition, the terrain topography and on-site facilities, including buildings, tanks and numerous pipeline corridors, restricted access to all proposed investigative locations.

Focus utilized its expertise in mapping and GIS, geophysical assessments, physical hydrogeology and contaminant transport modeling. Assessment activities at the site included:

  • Determination of source area and source characterization
  • Aerial delineation of impacts
  • Planning for and development and management of the containment and remediation strategies for areas impacted by LNAPL contaminants
  • Annual groundwater quality compliance monitoring.

Focus risk managed this project to protect potential human and ecological receptors, specifically the domestic use aquifer and ephemeral fresh water streams downgrade of the site.
