Phase II Soil Investigation and Phase III Soil Remediation
Confidential Aerospace Manufacturing Client
Saint-Leonard, Quebec, Canada

Following a Phase I ESA in which ETG recommended the removal of an area of contaminated soil at the Site, a local contractor was retained to excavate and dispose of the contaminated soils, replace the excavated material with clean fill, and repave the excavated area.  ETG was retained to assess the condition of the site following removal of soil, determine if the petroleum hydrocarbon concentrations in the remaining soils in this area were below the applicable provincial clean-up levels, direct any further soil removal if necessary, and provide a report detailing the results of the site assessment. During a visual inspection of the soil conditions at the Site, ETG personnel observed the fill material located on the west sidewall of the excavation and on the north side of the building appeared to be saturated with oil. ETG personnel collected soil samples from the area and they were analyzed for petroleum hydrocarbons (C10-C50). Concentrations of petroleum hydrocarbons were greater than established generic soil screening and cleanup guidelines. Thus, ETG supervised additional removal of soil at the Site and collected additional soil samples from the second excavation area. Samples were analyzed for petroleum hydrocarbon (C10-C50) and concentrations were below method detection limits or below established generic soil screening and cleanup guidelines.

Contaminated Soil Removal Project-Oversight, Sampling, and Reporting

ETG personnel supervised the removal of soil contaminated with petroleum hydrocarbons from the metal cutting storage area behind the client facility.  Based on field observations, ETG personnel directed the removal of contaminated soil with the goal of only removing the soil that is contaminated above the regulatory compliance levels. Samples were collected upon completing the excavation to document that remaining soils were below the regulatory compliance levels.  ETG prepared a report to document the project that illustrated the area of soil removal and presented volumes of excavated soil.  The report also documented the final disposition of excavated material, sampling locations and the results of the analytical testing.
