4 Steps
Soil remediation projects can vary greatly in regard to the size and scope of the project. Factors such as length of time a tank has been leaking, how much oil has escaped the tank into the surrounding soils, the location of the tank on the property, topography of the property, soil conditions on the property, and ground water table movement throughout the property all play a roll in the volume of contaminated soils that may need to be removed from a specific site.

Quote
A quote for soil remediation will be presented to the client. Soil remediation work is quoted separately from the removal of the underground storage tank. The quote for soil remediation includes all labour, required equipment, contaminated soil container and transport, contaminated soil disposal at a registered facility, backfill material and a final report documenting the soil remediation project.
02/
Sampling
During the course of a soil remediation project the clean overburden materials are stripped down to where the contaminated soils are present and stockpiled on site as room permits. The contaminated soils are then excavated from the original tank location outwards and removed under the direction of the environmental consultant.
After the excavation of contaminated soils has concluded, the signs of contamination are no longer present and clean soils are suspected to have been found the environmental consultant will collect a final round of soil samples from the excavation.

Implementation
Upon the collection of passing samples the site will be considered remediated and the excavation will be backfilled to grade with construction based backfill material.

Report
At the completion of the project a final report documenting the soil remediation project will be issued. The homeowner will also receive final report from the environmental consultant documenting the soil conditions.
A average residential soil remediation project is between 30-50 tonne. It is important to understand that this an average and some sites are more heavily contaminated then others.
Other than failing samples collected by the environmental consultant there are visual and olfactory indications soils may be contaminated. Soils that present as blue in colour and have the distinct smell of furnace oil when put to the nose are strong indications that contamination is present in the soils. These observations along with soil sampling done by the environmental consultant guide the progress of a soil remediation project.
There are three provincially regulated facilities on Vancouver Island set up to receive soils that are impacted by hydrocarbons. The data collected by the environmental consultant is reviewed by the facility and supporting documentation is issued allowing the facility to receive the contaminated soils from a specific site.
