Phase I Environmental Site Assessments

Documenting property conditions with respect to:

  • Chemical storage (service stations, heavy industrial facilities, farm storage)
  • Buildings
  • Historical land use
  • Potential sources and type of environmental concern(s) from on-site activities; and
  • Potential off-site impacts

for real estate transactions, financing or land re-development. Recommendations may be provided for further investigations, such as a Phase II Environmental Site Assessment.

Phase II Environmental Site Assessments

Work activities may include:

  • Initial exploratory investigations to collect soil and groundwater samples to answer:
    1. Where is the environmental concern?
    2. What are the contaminants of concern (fuel, solvents, metals, herbicides/pesticides, polycyclic aromatic hydrocarbons [PAHs], nutrients)?
  • Delineation investigations to document the extent of contamination and provide recommendations on clean-up (remedial) strategies.

Remediation

Providing recommendations for and implementing remedial strategies:

  • Excavation and appropriate Class II and/or Class I disposal
  • In-situ chemical or biological enhancement applications
  • Natural attenuation
  • Combined remedial strategies
  • On-going monitoring following full or partial clean-up

Often remedial strategies are complex, may take many years and may require the use of risk management (on-going monitoring, building control measures or limitations on land development) following partial removal of contaminant source(s).

  • Estimating volumes of waste/debris from properties with historic waste disposal
Pre-Waste Disposal
Post-Waste Disposal

Septic Field Investigations

Detailed septic field investigations and hydrogeological assessments following the Safety Codes Council Alberta Private Sewage Systems Standard of Practice (2021) and the Municipal Model Process for Subdivision Approval. Note that the new Standard of Practice comes into force November 1, 2022.
