Environmental Due Diligence

We wrote the book on environmental due diligence.

Environmental due diligence (EDD) refers to the evaluation of potential environmental concerns typically performed prior to a real estate transaction. This can include Phase I Environmental Site Assessments (ESAs), Phase II Site Investigations, or a wide range of other efforts to allow our clients to fully understand issues connected to a Site. We have experience working with a diverse set of discerning clients. This includes custom formats for some of the largest retailers in the world as well as individualized and site-specific approaches for our municipal clients. We are proud to be their trusted partners as they evaluate short-term cost implications, long-term liability, and innovative regulatory strategies to help them address these redevelopment barriers.

EDD will always be a core expertise for Modern Geosciences as our founding Principal, Kenneth Tramm, PhD, PG, CHMM, is a leading authority and the author of the environmental services industry’s go-to reference and college textbook: Environmental Due Diligence: A Professional Handbook.
