• Visual examination of site,
• Interviewing persons with knowledge of site (owners, tenants, prospective purchasers, etc.) 
• Assessment of historical records (land titles, municipal directories, aerial photographs, etc.)
• Contact with government and non-government agencies such as; Ontario Ministry of Environment (MOE) and Technical Standards and Safety Authority (TSSA), for records pertaining to the site
• Issuing a report outlining findings and recommendations on the environmental condition of a site

Phase II Environmental Site Assessment:

An invasive subsurface investigation whose purpose is to define and delineate any contamination that may be present on a site, as a result of findings of a Phase I Environmental Assessment. The Phase II Environmental Site Assessment is completed by a “Qualified Person” (QPRSC) and meets the requirements of Ontario Regulation 153/04, Records of Site Condition.  The investigation includes:

• Obtaining samples of subsoils and groundwater for site-specific chemical analysis
•  Determination of applicable criteria for chemical analysis based on use of site, in conformance with O. Reg. 153/04.
• Interpretation of test results including Risk Assessment and development of Conceptual Site Model
• Issuing a report outlining findings and providing site-specific remediation plan, if warranted 

Remediation & Decommissioning:

• Determining extent of contamination by way of subsurface soil and groundwater sampling for site-specific parameters, in conformance with O. Reg. 153/04
• Devising both in-situ and ex-situ soil and groundwater remedial plans
•  Supervising remedial procedures and carrying out confirmatory sampling of soils and groundwater
•  Monitoring underground storage tank (UST) removal

Hydrogeologic Services:

• Determination of groundwater level and direction of flow
• Recommendations on effects of water table on foundations, excavations and subsequent dewatering measures
• Analysis of groundwater for purpose of discharge into sewers
• Recommendations on groundwater remediation
•  Analysis, design and recommendation on subsurface drainage, surface water management and infiltration systems
