Environmental contamination can present potential risks to property occupants, workers, surrounding properties, future land use, and property transactions. BNF provides Phase I and Phase II Environmental Site Assessments (ESAs) for commercial, industrial, and development properties. Phase I assessments evaluate historical property use, regulatory databases, environmental records, adjoining and surrounding properties, site reconnaissance, and other relevant information to identify recognized environmental conditions (RECs), controlled RECs, historical RECs, and other potential environmental concerns, as applicable under the assessment standard. Where warranted, Phase II investigations use soil, groundwater, soil-gas, indoor-air, surface-water, or other targeted environmental sampling and laboratory analysis to investigate potential impacts identified during the Phase I assessment. Assessments may be performed in accordance with applicable ASTM standards, EPA requirements, state environmental programs, and applicable regulatory requirements, depending on the project.
