Air & Water Sciences is exceptionally qualified to perform Phase I and II investigations. Our expertise in indoor air quality, water and vapor intrusion, mold, asbestos and lead combined with extensive experience with investigation and remediation of soil and groundwater contamination allow us to provide comprehensive Phase I and II investigations. We provide our clients with an evaluation of existing and potential environmental liabilities as well as recommendations and cost estimates for remediation of environmental contamination necessary for our clients to make informed decisions with respect to property transactions.

Phase I investigations are most often requested by a buyer or seller of real property and/or a lender. The goal of the Phase I is to identify existing or potential environmental liabilities associated with both the land and the structures. Phase I investigations often include but are not limited to:

  • Visual inspection of structures for potential asbestos, lead, mold or vapor intrusion concerns
  • Visual inspection of undeveloped portions of the site for potential evidence of soil contamination, improperly stored hazardous materials, chemical disposal, drainage from adjacent properties
  • Records review of current and historical uses
  • Interviews with owners, operators and employees (past and present)
  • Review of historical records and aerial photographs
  • Reviews of regulatory agency files regarding any water quality or soil contamination concerns on subject property or nearby properties
  • Report summarizing findings
  • Recommendations for Phase II work (if warranted)

Phase II investigations are conducted if any potential environmental concerns or liabilities are identified during the Phase I investigation. The goal of Phase II is to confirm and quantify potential environmental concerns and liabilities. Phase II consists of collecting samples of building materials, soils, water, and groundwater as needed based on the Phase I recommendations. Phase II investigations may include but are not limited to:

  • Testing of building materials for asbestos, lead, mold and/or bacteria
  • Soil sampling (surface and subsurface)
  • Soil sampling (surface and subsurface)
  • Groundwater sampling
  • Sample analyses of soils and water for contaminants such as petroleum hydrocarbons, heavy metals, solvents, pesticides
  • Soil gas testing
  • Report summarizing findings
