Phase II & III Environmental Site Assessments
ORTAM’s highly trained team of professionals will conduct the Phase II or III Environmental Study using proven and reliable investigative methods.
Phase II or Phase III Environmental Study
The purpose of a Phase II environmental site assessment is to determine if potential contaminants of concerns identified in the Phase I study are present in amounts or concentrations exceeding the limits established by the MLECC. The objective of Phase III is to determine the extent of contamination identified in Phase 2.
The investigation is intrusive and typically involves excavation, and drilling, and in most cases requires the use of an excavator or drill rig.


How A Phase II or III Environmental Site Assessment Works
A Phase II or Phase III Assessment includes:
A thorough review of past studies and documentation provided by the client, and interviews with resource personnel
Planning and execution of a sampling campaign
Collection of soil, vapour, sediment, groundwater, or surface water samples for analysis to identify the specific contaminants of interest.
Execution of fieldwork, including underground infrastructure locates
Interpretation of Data & Report
