Phase 1 Desk Studies

Desk studies are an essential first phase of any site investigation. Environmental database, historical and geological map information are obtained and reviewed. A site walkover survey and general internet searches are undertaken. The information is used to build up a preliminary conceptual site model (CSM) for the site. The CSM identifies potential on and offsite sources of contamination, potential targets (receptors) which the contamination could effect (e.g. rivers, aquifers, human health) and potential pathways whereby the contamination could affect the identified receptors. Potentially significant pollutions pathways are identified in a Preliminary Risk Assessment.
