Environmental Insights. Smarter Development.

How can we help?

At Troxler Environmental, we guide you through every step of environmental due diligence with clear, expert support.

  • Phase 1 ESA: We identify potential environmental risks on a property through research, site visits, and interviews—helping you uncover issues before you buy or develop.

  • Phase 2 ESA: If further investigation is needed, we conduct soil, groundwater, and material testing to confirm or rule out contamination—so you can move forward with confidence.

Whether you’re buying, selling, or developing, we make sure your project stays compliant, informed, and on track.

How long are Phase 1 and Phase 2 ESAs valid?

A Phase 1 ESA is considered valid for 6 months and may be updated within 1 year. A Phase 2 ESA’s relevance depends on the conditions of the site but typically remains valid as long as no significant changes occur.
