Phase 2 Environmental Site Assessments

A Phase 2 ESA is the next phase of the process if environmental concerns arise during the previous Phase 1, or other ESAs.

A Phase 2 ESA is the systematic process where physical samples and testing take place to characterize environmental conditions related to the property. A Phase 2 ESA can confirm or refute the potential contamination identified in a Phase 1 ESA, provide supplemental information for previous Phase 2 ESAs and provide the basis for evaluating site remediation needs.

A prescriptive guide for Phase 2 ESAs is difficult to develop due to varying site conditions (e.g. soils, geography, topography, site operations, and contamination types). However, JADA Solutions (HSE) Inc. has developed an outline for oil and gas, commercial, and industrial activities that will aid in assessing the nature and extent of any contamination on the property. JADA Solutions (HSE) Inc’s methodologies is based on the standardized and generally agreed upon procedures of the Canadian Standard Association (CSA) 769-00 (R2008) – Phase II Environmental Site Assessment. Using the CSA standard guarantees the appropriate combination of formal education, skill, experience and training to provide a technically sound Phase 2 ESA.

Phase 2 Components:

  • A review of Phase 1 and Phase 2 ESA information;
  • Development of a health and safety plan;
  • Development of Quality Assurance and Quality Control plan;
  • Development of a site investigation plan;
  • Completion of a site investigation (includes geophysical work, sample collections);
  • Interpretation and evaluation of analytical data from the site investigation;
  • Estimation of the lateral and vertical extent of the contamination;
  • A detailed description of remediation activities;
  • Confirmatory sampling locations and analytical data; and
  • Preparation of a factual report-confirming laboratory reported results and recommendations if required.

The Phase 2 ESA can entail digging of test pits, drilling of boreholes, and or installing groundwater-monitoring wells.

Once a Phase 2 is completed a Phase 3 Environmental Site Assessment may be required.
