What is the objective?
How might this be done?
Frequently it is done by removing the contaminated soil and disposing of it in a licensed landfill.
It can sometimes be done by treating the soil on site. This may or may not be practical depending upon the type of contaminants and size of site.
It may be possible to introduce a barrier between the contaminants and people who will be using the site. This barrier may be a purpose made membrane, a hard surface such as block paving or asphalt or a suitable depth of clean soil.
The contaminated areas may be suitable for some uses but not others, in which case it may be possible to amend the site layout so that for example the contaminated area is used as a car park instead of gardens.
In the case of ground gas or vapours the solution is often to introduce a membrane to prevent the gas or vapour entering the buildings where it could cause harm.
What happens when the remedial works are complete?
Within the Remediation Strategy there will be a verification plan setting out the requirements for testing, monitoring and documentation required to demonstrate satisfactory remediation. On completion of remediation the Verification Report has to be completed.
