Environmental Site Assessments | Oakhill Environmental

We all desire to live and work in an environment, where the land is composed of only what nature intended. This is not always the case.

Environmental Site Assessment

In the environmental industry an environmental site assessment (ESA) is a way to analyze the potential environmental impacts on any given property, specifically soil groundwater, sediment, and surface water. During commercial and industrial property transactions, it is in the best interest of all parties to obtain the input of expert environmental consultants, such as Oakhill, in order to conduct due diligence and identify potential environmental liabilities associated with a site. furthermore, the environmental Site Assessment process is a regulatory requirement to obtain a Record of Site Condition.

Phase One Environmental Site Assessment (ESA) – The process of identifying any historical or current activities (on-Site or off-Site) that may impact the environmental condition of a site.
Phase Two ESA – Conducting intrusive sampling (i.e., soil, groundwater, soil vapour, sediment, and/or surface water) to assess the potential or known impacts to the environmental condition of a Site.
Environmental Drilling & Monitoring – Utilization of in-house drills and drilling subcontractors to complete boreholes and groundwater investigations as part of Phase 2 ESAs.
Phase Three ESA (i.e., Remedial Efforts) – The evaluation of remedial options and implementation of an effect remedial strategy to address contamination identified during a Phase 2 ESA.
Risk Assessment – A tool utilized to assess existing contamination (i.e., after Phase Two and/or Phase Three work has been completed), and determine the level of risk to human and ecological receptors. A Screening Level Risk Assessment (SLRA) is typically completed to support due diligence projects (excluding Records of Site Condition), where as a Risk Assessment (RA) is completed to support a Record of Site Condition filing.
Record of Site Condition – Submission of Conceptual Site Model to the Ministry of the Environment, Conservation and Parks, following completion of the ESA process to support a change of property use (i.e., development permitting requirements).
