Phase I & II Environmental Site Assessments

A Phase I Environmental Site Assessment consists primarily of the following components:

  • An on-site reconnaissance of the property, including a cursory observation of adjacent properties;
  • Interviews with owners/occupants and local government officials to obtain information indicating recognized environmental conditions in connection with the property;
  • A review of various records to help identify recognized environmental conditions in connection with the subject property and nearby properties; and
  • Preparation of a final report which details the assessment findings and includes supporting documentation.

A Phase II Contaminant Investigation is also known as a Phase II Environmental Site Assessment and can be defined as the investigation of real property through physical samplings and analyses to determine the presence, nature and extent of contamination and if present, a description of the recommended remedial method. In the event that contamination is suspected or found, OGI Environmental’s staff is technically trained and experienced to conduct the necessary Phase II contaminant investigation or site characterization, which is usually proposed to deal with soil and/or groundwater contamination. OGI uses investigative techniques including: soil borings, hand augering, test pits, temporary or permanent monitoring wells, soil and groundwater sampling, directional drilling, soil gas surveys, geophysical methods, pump tests, groundwater modeling and other methods, to ensure that characterization is thorough. The information developed from the investigation is used to evaluate additional investigative requirements and/or the feasibility of various cleanup alternatives using factors which include cost, effectiveness, duration, and health risk.
