Environmental Site Assessments
Identify and manage your environmental risk
The presence of contamination on a property identified and confirmed during Phase I and II Environmental Site Assessments (ESA) implies the possibility for migration of those contaminants to adjacent properties and therefore creates existing or future environmental liability on the part of the property owner or associated financial institution.
Phase I environmental site assessments
A Phase I ESA is a non-intrusive investigation during which Cambium Environmental staff use their knowledge and expertise to identify actual and potential areas of environmental concern based on the information gathered during a site inspection, records review, and interviews with individuals with specific knowledge of the site in question.
During the site inspection, Cambium Environmental will examine all areas of the property to identify environmental concerns such as:
- Underground and above ground storage tanks.
- Materials handling, storage and disposal practices.
- Hazardous materials.
- Potential contaminant pathways.
Typically, a Phase I ESA is conducted prior to the close of a real estate transaction, often at the request of the lending institution. As it provides an environmental record of the site, this type of investigation is also beneficial for use prior to major renovations or changes in the type of activity taking place on a property.
The investigation and resultant report completed by Cambium Environmental for Phase I ESAs are based on the Canadian Standards Association Standard Z768-01 and Ontario Regulation 153/04.
Phase II environmental site assessments
A Phase II ESA is an intrusive investigation used to confirm the presence or absence of contamination and/or hazardous materials that may have been identified during a Phase I ESA. Activities involved in the completion of a Phase II ESA may include:
- Excavation of test pits.
- Installation of boreholes or monitoring wells.
- Environmental measurement.
- Collection and analysis of environmental samples.
The results of the Phase II ESA will define the nature and extent of any contamination and/or hazardous material present at the site. In cases where the nature of activities, either current or historic, occurring on the subject site or on adjacent properties indicates a probable source of contamination, cost savings can be realized by conducting the Phase I and II investigations in parallel.
The investigation and resultant report completed by Cambium Environmental for Phase II ESAs are based on the Canadian Standards Association Standard Z769-00 and Ontario Regulation 153/04.
Records of site condition
The province of Ontario through the Brownfields Statute Law Amendment Act, 2001, requires mandatory filing of a Record of Site Condition for prescribed changes in property use. Some municipalities may also require a Record of Site Condition for substantial property re-development where a change in property use is not intended. Cambium Environmental is able to prepare and file a Record of Site Condition utilizing our team of qualified professional engineers, hydrogeologists, scientists and GIS experts.
