Contaminated Sites

From initial site screening through to regulatory closure — practical, senior-led expertise at every stage.

Phase I Environmental Site Assessment

A Phase I ESA is a non-invasive review of a property’s history and current condition to identify actual or potential contamination. EnviroSearch Ltd. provides Phase I ESAs for a full range of property types — from oil and gas infrastructure to commercial and industrial sites — delivering clear, actionable findings to support transactions, due diligence, and regulatory requirements.

Phase II Environmental Site Assessment

Where a Phase I identifies concerns, a Phase II ESA confirms or rules out contamination through targeted sampling and analysis. Our approach is phased and efficient — we tailor the scope to what the site actually needs.

  • Soil, groundwater, surface water, vapour, and sediment sampling
  • Laboratory analysis for site-specific contaminants of concern
  • Groundwater elevation and flow characterization
  • Comparison against applicable regulatory criteria
  • Clear, regulator-ready reporting

Remediation

EnviroSearch Ltd. develops and oversees remedial programs that are practical, cost-effective, and calibrated to achieve regulatory closure. We apply both proven and innovative strategies based on site-specific conditions — and we treat your budget like it’s our own.

A well-scoped risk assessment can sometimes demonstrate that remediation is not required — saving significant time and cost while still satisfying regulators.

Risk Assessment & Management

Our scientists have extensive experience preparing human health and ecological risk assessments under Alberta and other western Canadian regulatory frameworks. Risk assessment can be used to prioritize remedial targets, develop site-specific criteria, or demonstrate that current risk levels are acceptable.

Field Services

EnviroSearch Ltd. employs experienced field personnel who support all phases of site assessment and remediation:

  • Soil and groundwater sampling and monitoring
  • Borehole drilling supervision and sampling
  • Underground storage tank (UST) monitoring and compliance
  • Domestic water well baseline testing
  • Biophysical data collection for site and impact assessments
