Phase I (Desk-Top) Site Investigations

A Phase I (Desk-Top Study) Site Investigation is the initial stage of environmental site investigation. It is used to characterise the past and present activities of a site which could have led to any potential contamination (sources) occurring. It also establishes any receptors and pathways which may be present and therefore any potential pollution linkages associated with the site.

The site investigation involves looking at a range of information including historical, geological and hydrogeological maps, trade directories, past environmental reports, and information held by local authorities. It also includes a site reconnaissance (walk over) to establish basic information on the current site conditions. The collated information is used to construct a conceptual site model and assess if significant potential pollution linkages are present at the site. If potential significant risks to receptors are found, further phases of investigation may be required
