Site investigation and sampling to assess contamination

As the pressure to build on Brownfield instead of Greenfield sites increases, it is more likely that sites with previous contamination will be redeveloped. It is therefore important to determine the level of contamination present by carrying out a full site investigation and direct sampling on site of potentially contaminated areas. The results can be used to determine the remedial treatment required to allow the land to be developed.

Key environmental issues include:

• determining the likely location and scale of contamination (in consultation with contractors and historical site records)
• determining previous land use (e.g. possible occurrence of oil storage tanks)
• handling and storage of materials that are potentially contaminated (e.g. soil)
• waste disposal of potential hazardous material (having acquired appropriate licenses to do so).
