A Phase I Preliminary Risk Assessment forms the basis of any contaminated land investigation.

The purpose of a Phase 1 Land Contamination Assessment or Preliminary Risk Assessment (PRA) is to establish the previous uses of the land under consideration or land nearby or adjacent to it, and to identify potential sources of contamination, receptors and pathways. It is important to identify all past uses of the site, and adjacent or nearby sites, since pollutants have the potential to travel away from the source, depending on the geology, groundwater and surface water of the area.

Phase 1 Preliminary Risk Assessments are generally all that is required required at the planning application stage and although further investigations may be required these can be conditioned if required.
