An Essential Guide to Desktop Study: An Important Part of Land Risk Assessment

A contaminated land environment Phase 1 Desktop Study is a crucial part of contaminated land risk assessment. Why has it been designed? It has been intended to provide a qualitative assessment summary of the vulnerabilities to the existing and future occupants and the wider environment due to the presence of any contamination on or in close proximity to the proposed study site. 


If going on for the Contaminated Land Assessment in West London, then read on further to get more details about the Phase 1 Desktop Study and what all it entails:

Evaluate the Potential Risks

Before purchasing a site, it is important to identify and assess if there are any risks which are linked with a site and the possible obligations that the buyer may have to undertake. This may further affect the value of the site.

  • Site details: It reveals the facts like site detail, site boundaries, proposed site use, details of the walkover survey, present land use. 
  • Historical appraisals- It encompasses an investigation of historical ordinance survey plans of the past uses and structure on-site and the immediate surrounding region. 
  • Environmental appraisals- Environmental appraisals include potential contamination sources, landfill sites, hydrogeology, and flooding, etc. 
  • Geological Appraisals: There come the considerations like artificial grounds, bedrock, mining, natural ground subsidence, etc., under geological appraisals. 
  • Conceptual ground model- Under conceptual ground models, there is the preliminary risk assessment of potential ground-related hazards.  
  • Site investigation:  It includes the recommendations related to contamination analysis, ground gas monitoring (if required).
