Phase II Environmental Site Assessments

 

The purpose of a Phase II Environmental Site Assessment or a Stage 2 Preliminary Site Investigation is to identify actual and potential contamination, per the Canadian Standard Association (CSA) Phase II ESA Standard Z769-00.  The objective of a Phase II ESA / Stage 2 PSI is to define the nature and extent of any environmental impacts at a site through an intrusive investigation program.  A Phase II ESA / Stage 2 PSI is the evaluation of recognized environmental conditions (i.e. confirmation of the significant potential of a release into soil, groundwater, or structures on a property). In BC, the Oil & Gas Commission requires that groundwater assessments are a mandatory part of Phase II ESAs / Stage 2 PSIs.  The Contaminated Sites Regulation requires vapour monitoring to determine whether any soil, sediment or water releases contain vapour concentrations in excess of the CSR standards.

Groundwater assessments are important in determining the groundwater beneath your site and in excluding both soil and groundwater pathways.  Determining groundwater flow and direction is vital in trying to evaluate the magnitude of any groundwater contamination. Protection of groundwater is vital as lower precipitation in Western Canada in the past 30 years has lowered groundwater tables. By reducing the pathways, less risk is identified.

 

Elkan personnel have conducted hundreds of soil and groundwater monitoring programs, from very small programs to monitoring programs at large-scale gas plants.  Reporting for monitoring programs has involved submission of reports to regulatory agencies, where specific reporting requirements were outlined and deadlines were established. Comprehensive reports were provided within the deadlines established.
