When it comes to risks of building on brownfield land, the risk from potential contaminated land perhaps tops the list.
By understanding and managing these risks from the outset, the impact of dealing with land contamination relating to issues of programme, cost, regulators and third party perceptions can be minimised. With proper assessment and where required, remediation, the reward of developing a brownfield land can far outweigh the risks.
The assessment of brownfield is a phased approach. This is often reflected in a planning permission, but is detailed within BS10175 “Investigation of potentially contaminated sites. Code of practice”, and Environment Agency CLR11 “Model Procedures for the Management of Land Contamination”. The stages are summarised below.
- Phase 1 Desk Study. This is based on desk based research to establish what the possible risks may be.
- Phase 2 Site Investigations. The preliminary site investigation will test the assumptions made in the Desk Study and establish if contamination may be present. Subsequent investigations may be required to delineate the contamination or further test assumptions.
- Remediation. Depending on what is found, the remediation may be a simple exercise, or a long term approach. In some cases, a Remediation Options Appraisal and Method Statement may be required.
- Validation. Once the remediation has been completed, a Validation Report (essentially a closure report) will be required that details the work that was undertaken and identifies that no further risks remain.
