An Environmental Site Assessment – ESA – identifies potential liability-related environmental contamination for real estate holding companies, sometimes as a prelude to additional sampling to assess the need for improvement, remediation and/or restoration of the property.
Sampling of soil, air, groundwater and/or building material is typically not part of this assessment, as a Phase 1 assessment starts a due diligence process. If a structure is thought to be contaminated, a further assessment may be conducted.
Indoor air quality (IAQ) is the condition of a home's or building’s indoor air as it relates to health. ESC uses a variety of methods to assess the condition of indoor air and report it accurately to the customer along with practical advice if requested on what to do if problems are found.
Visual and other inspection of impacted areas is performed to determine the scope of the moisture/mold problem.
ESC determines moisture levels of materials, and indoor/outdoor air using reliable scientific measurement to locate the source and extent of moisture, and if requested, a strategy to correct a problem.
Surfaces are visually inspected and physically contacted to determine if they contain debris and e.g., to determine if discolored materials contain mold growth. Appropriate industrial hygiene methods are used during the investigation.
Note: there are no regulatory standards for acceptable levels of fungal microorganisms in residential indoor environments.
ESC can inspect your home or building to see if there are sources of lead exposure such as peeling paint and lead dust, and advise you on what to do to address the hazard.
ESC will check surfaces and the air for contamination using proven methods established by reputable organizations such as the American Industrial Hygiene Association (AIHA).
