Phase II & III ESA

If you suspect potential contamination on your property, or if you are undertaking a construction or development project requiring the off-site movement of soil, or if your Phase I ESA has indicated the presence of potential contamination, chances are that you will require a Phase II ESA. A Phase II ESA is an intrusive site assessment with the primary purpose of defining the presence or absence of contamination on a property. A Phase III ESA is the same as the Phase II ESA; however, the primary purpose of these assessments is the vertical and horizontal delineation of contaminants for the purpose of remediation or risk management planning.

Envirotech has significant experience conducting Phase II and Phase III ESAs. Our Phase II and Phase III ESAs may include some, or all, of the following components:

  • Buried Utility Locates and Baseline Property Surveys;
  • Prime Contractor Management and Site Safety Programs;
  • Subcontracting Intrusive Sampling Equipment and Manpower;
  • Installing Groundwater Monitoring Wells;
  • Collecting of Soil, Groundwater, Surface Water, Sediment and/or Vapour Samples;
  • Laboratory Analysis;
  • Post Assessment Surveying and Groundwater Monitoring;
  • Assessment Criteria Selection & Data Interpretation; and  
  • Alberta Environment and Parks (AEP) Record of Site Condition Reporting.

Our Phase II and III ESAs are completed in accordance with industry accepted standards and the Canadian Standards Association (“CSA”) document entitled CAN/CSA-Z769-00 (R2008) Phase II Environmental Site Assessment. Our sampling protocols adhere to the relevant sections of the AEP Tier 1 Soil and Groundwater Remediation Guidelines, the AEP Tier 2 Soil and Groundwater Remediation Guidelines, other provincial reference criteria, or where appropriate, the federal Canadian Council of Ministers of the Environment (CCME) Guidelines.

An AEP Record of Site Condition report form and submission is required for all Phase II and III ESAs in Alberta. The public record submission is disclosed in accordance with Section 35 of the Environmental Protection and Enhancement Act, Disclosure of Information Regulation, and Ministerial Order 23/2004.

Do you require a Phase II or III ESA? Please feel free to Contact our Assessment Remediation Division for more information or a quote.
