Phase 1 Environmental Assessments

Many projects involve building on Brownfield sites which have been subject to various previous uses that could have contaminated the ground. The costs involved in chemically testing the ground for the presence of all possible contaminants at all locations would be prohibitively high. We aim to keep these testing costs to a minimum by providing our Clients with a Phase 1 Environmental Desk Study that enables us to specify a specific testing regime.  This avoids testing for contaminants where we have identified no historic site uses or neighbouring activities associated with such contaminants.  The risks from contaminants to sensitive receptors such as humans, animals, plants as well as the local air and water environment are assessed to confirm if any mitigation measures are actually required.

Our Phase 1 reports involve the following:

  • Examining Historic and Geological Mapping Records and Documentation.
  • Establishing the Previous, Potentially Contaminative, Uses Of The Site.
  • Establishing the Potentially Contaminative Uses Of Surrounding Land.
  • Identify the Contaminants (Sources) Potentially Associated With These Uses.
  • Identify the Environmental Receptors Potentially At Risk From Identified Contaminants.
  • Establish the Potential Physical Pathways Linking Potential Sources And Receptors.
  • Highlight Factors Influencing Source-Pathway-Receptor Linkages.
  • Compare Threshold Levels For Remedial Actions.
  • Provide a Specification for the Phase 2 Intrusive Site Investigation works.
  • Provide an Appraisal Of Potential Remedial Options Within a comprehensive Report.
