LRL’s Environmental Services Team was retained to complete a Phase ll Environmental Site Assessment (ESA) on the grounds of an Ottawa area property to determine if recognized potential environmental concerns have negatively impacted the quality of the soil and groundwater of the subject Site. Such an assessment provides information regarding the nature and extent of potential contamination to assist in making informed business decisions about the property.
Potential environmental concerns identified, that required investigation included a previous hydraulic oil spill; the storage of diesel fuel on the subject site; the presence of an electrical transformer; neighbouring lands registered as waste generators, PCB storage or handling facilities; neighbouring spills and fuel storage tanks; federal contaminated lands and former quarry activities.
The scope of work included the advancement of several boreholes across the property at strategic locations to address the areas of concern. Select boreholes were completed into groundwater monitoring wells to assess hydrogeological conditions and facilitate groundwater sampling. Subsequent groundwater sampling results, in conjunction with the analysis of select soils samples were used to establish the subsurface conditions of the site, and confirm the presence of potential contaminants of concern.
