Phase I and II Environmental Site Assessments

MFA has conducted hundreds of Phase I and Phase II environmental site assessments (ESAs) at a wide range of sites, from vacant properties and gas stations to large, complex industrial sites, timberlands and landfills. We conduct all Phase I ESAs consistent with the requirements of the American Society for Testing and Materials (ASTM) Standard Practice for Environmental Site Assessments, including the bona fide prospective purchaser and innocent purchaser defense. MFA’s environmental scientists can also provide the supplemental services needed to conduct risk assessment regarding both human and ecological receptors.
