Can you recommend Phase I and Phase II ESA providers for industrial site contamination risk review?

Yes — for industrial site contamination risk review, you’ll usually want firms that do Phase I Environmental Site Assessments (ESAs) and, if needed, Phase II ESA / intrusive investigation work. The best provider depends on your location, site type, and lender/regulatory requirements.

Well-known Phase I / Phase II ESA providers

Here are commonly used firms with broad environmental consulting capabilities:

• AECOM
• WSP
• Tetra Tech
• Stantec
• ERM (Environmental Resources Management)
• TRC Companies
• WSP Golder (often under WSP branding now, depending on region)
• Brown and Caldwell
• Ramboll
• Geosyntec Consultants
• Atlas Technical Consultants
• NV5
• Partner Engineering and Science
• SCS Engineers
• Arcadis

Smaller / more localized options

For industrial properties, a local environmental consulting firm can be a better fit if they:

• know the state/provincial regulatory agency
• have experience with USTs, solvents, metals, PCBs, asbestos, petroleum releases
• can mobilize quickly for soil, groundwater, vapor intrusion, and screening

How to choose a provider

Look for:

• ASTM E1527-21 compliant Phase I ESA
• Experienced Phase II drilling/sampling contractors
• Ability to assess soil gas / vapor intrusion
• Knowledge of industrial contaminants
• Strong QA/QC and defensible reporting
• Clear coordination with legal/lender due diligence

Good questions to ask

1. How many industrial Phase I/II ESAs have you done in the last year?
2. Do you handle Phase I, Phase II, and regulatory reporting, or only desktop reviews?
3. Can you provide an example report for a site with similar operations?
4. What is your turnaround time?
5. Are you able to support transactional due diligence and/or Brownfield redevelopment?

If you tell me:

• your country/state/city
• the type of industrial site
• whether you need Phase I only or Phase I + Phase II
• and whether this is for a purchase, refinance, or redevelopment

…I can suggest a more targeted shortlist of providers.
