Environmental Site Assessments

Any piece of real estate can be the subject of a Phase I - Environmental Site Assessment.  (ESA). Generally speaking, Phase I - ESAs are reports prepared for a real estate holding which identify potential liabilities associated with existing environmental contamination.   ESAs typically address both the underlying land as well as physical improvements to the property.  Actual sampling of soil, air, groundwater and/or building materials is typically not conducted during a Phase I ESA.  The Phase I ESA is generally considered the first step in the process of environmental due diligence.   The examination of a site may include: definition of any chemical residues within structures; identification of possible asbestos containing building materials; inventory of hazardous substances stored or used on site; assessment of mold and mildew; and evaluation of other indoor air quality parameters.  The investigation also includes examination of potential soil contamination, groundwater quality, surface water quality and sometimes issues related to hazardous substance uptake by biota.

Soil Vapor Intrusion

The phrase “soil vapor intrusion” refers to the process by which volatile chemicals migrate from a subsurface source, through soil vapor and into the indoor air of a building where an adverse exposure is possible. Soil vapor, also referred to as soil gas, is the air found in the pore spaces between soil particles (Figure 1). Soil vapor can enter a building through cracks or perforations in slabs or basement floors and walls.  Additional points of entry may include openings around sump pumps or where pipes and electrical wires go through the foundation,  Migration occurs due to differences between interior (within the structure) and exterior (within the soil) pressures.  Specifically, if the contaminant vapor migrates into the radius of influence of an existing building, then typical building pressure differentials related to heating or cooling systems can draw the contaminant vapors into or below the structure where it could accumulate.
