What Does a Phase 1 Desktop Study Entail?
You typed “what’s in a Phase 1 Desktop Study?”—here’s the inside scoop.
A Phase 1 Desktop Study is a structured process:
Data Gathering
- Historical maps (from the 19th century onward)
- Aerial photographs (to spot past site features)
- Trade directories (identifying former industrial tenants)
Regulatory Searches
- Environment Agency registers (pollution incidents, landfill sites)
- Local authority records (planning applications, enforcement notices)
Geological & Hydrogeological Review
- Soil classifications, aquifer vulnerability, groundwater flow
Site Walkover (Optional but recommended)
- Visual inspection for signs of contamination: staining, odors, pipework
Risk Assessment & Reporting
- Assigning risk levels (low, moderate, high) to identified hazards
- Clear maps, tables and narrative explaining findings
- Recommendations: no further action, Phase 2 invasive investigation, or remediation options
Q: Do I need the site walkover?
A: If you’re on brownfield or industrial land, yes—walking the site can spot surface clues a desktop review misses.
Turnaround: Most Phase 1 Desktop Study reports are delivered within 7–10 working days, faster if you need a quick check before exchange of contracts.
