Background to Contaminated Land Northern Ireland / Contaminated Land Belfast
The Model Procedures for the Management of Land Contamination (CLR11) has been developed to provide the technical framework for applying a risk management process when dealing with land affected by contamination. The process involves identifying, making decisions on, and taking appropriate action to deal with, land contamination in a way that is consistent with government policies and legislation within the UK.
CLR11 indicates that the assessment of land for contamination should always start with a Phase 1 Preliminary Risk Assessment (PRA), with the following objectives;
- Define the objectives of the assessment;
- Collect basic information about the site;
- Decide if further assessment of the site is required.
If the Phase 1 PRA identifies unacceptable human health and / or environmental risk, then the site will have to be further investigated by way of an intrusive investigation (soil, groundwater, ground gas and surface water) and the information obtained from this assessed (Quantitative Risk Assessment). If this further assessment indicates unacceptable pollutant linkages, a Remediation Strategy is developed to break the identified linkages. In order to confirm the Remediation Strategy has been correctly incorporated into the final development, a Remedial Validation Report is produced.
