OIL TANK SITE REMEDIATION
Remediation of the oil tank site encompasses both surface and subsurface activities designed to address both the pollution issues of leaking oil and visual appearance of your property.
Any pollution caused by your leaking in ground oil tank is addressed in the underground oil tank removal following manner.
- A composite of soil samples collected is submitted to a certified laboratory for TPH analysis.
- Based upon the results of that analysis, MTR will return to the site to excavate the contaminated soil. During this phase, a LEP is often present to determine the extent of required excavation.
- The LEP documents conditions, records headspace readings, segregates petroleum-impacted soil and collects post-excavation soil samples using a PID to establish TPH by measuring the concentration of volatile components such as benzene.
- The soils above the “plume”, the area of unacceptable levels of contamination, are excavated and set aside for use as clean fill upon completion.
- Contaminated soil is then excavated and trucked from your property to a disposal facility (either an incinerator or landfill) licensed to handle oil-contaminated soils
- Where the soil can not be removed, as in those cases where oil had seeped under your house, a passive venting system like that shown at right, draws the hydrocarbon vapors out of the soil
- Where a well which supplies drinking water is nearby, we test the well water to determine whether or not it’s purity has been compromised by the leaking oil
- Clean fill is trucked in to replace the soils that were removed and the upper layers of soil that were stockpiled on-site are also used.
- The area is then seeded or sodded according your agreement with us.
- Tracks and ruts created by the our equipment during the process are also filled, rolled and seeded or sodded in accordance with your agreement with us.
- A closure report is prepared and submitted to the property owner within a few weeks of laboratory analysis of final soil samples. Click here to see a typical closure report.
