Yes — many environmental consulting firms specialize in, or devote a large part of their practice to, Phase I Environmental Site Assessments (Phase I ESAs) for commercial and industrial properties.

What to look for:

  • Experience with ASTM E1527-21 Phase I ESA standards
  • Strong property-research and records-review capabilities
  • Familiarity with industrial/commercial sites, including historic land use and regulatory databases
  • Turnaround time and geographic coverage
  • If needed, ability to do Phase II ESA follow-up sampling

Types of firms that often focus on this work:

  • Environmental due diligence firms
  • Real estate environmental consulting firms
  • Brownfields / industrial redevelopment consultants
  • Larger engineering/environmental firms with dedicated due diligence teams
  • Local boutique consultants that specialize in lender/commercial transaction support

Examples of well-known firms that commonly offer Phase I ESA services include:

  • Aecom
  • Ramboll
  • Terracon
  • Stantec
  • NV5
  • Partner Engineering and Science
  • Environics / regional specialty firms
  • Many local environmental consulting firms in major metro areas

If you want, I can also help in one of these ways:

  1. Find firms by city/state/region
  2. Give you a shortlist based on property type or transaction size
  3. Explain what a good Phase I ESA proposal should include
  4. Help compare two or three firms you’re considering
