Phase One Environmental
Site Assessments

Environmental Assessments

Our Phase One Environmental Site Assessments (ESAs) are conducted using a systematic approach to identify potential environmental concerns.

This initial phase involves a review of historical and current site activities, including aerial imagery, city directories, and government databases. On-site inspections and interviews with knowledgeable individuals are integral to our process.

Phase Two Environmental Site

Peritus Environmental specializes in coordinating and executing Phase Two Environmental Site Assessments for various property types and scenarios. The primary purpose of Phase Two Environmental Site Assessments is to investigate whether contaminants are present in the potential areas identified by the Phase One assessment and to establish a baseline understanding of their location and concentration.

Our Phase One and Two Environmental Site Assessments adhere to the standards outlined in Ontario Regulation 153/04 or the Canadian Standards Association (CSA-Z769-00). These ESAs are essential for property transactions and development endeavours.

Risk Assessments & Risk Management

Contamination revealed in a Phase Two Environmental Site Assessment does not always mean extensive and costly remediation efforts. Our Risk Assessments determine if the identified issues pose risks to human and ecological health. This approach is particularly valuable when traditional remediation is not feasible due to technical, financial, or project timeline considerations.

Our experienced Qualified Persons Risk Assessment (QPRA) have successfully navigated a diverse range of contaminated scenarios, securing our position among Ontario’s top five companies with the highest number of approved risk assessments under the revised Ontario Regulation 153/04.

Peer Review

Peer Review

Recognizing the importance of a comprehensive technical assessment, our commitment to excellence extends beyond our own projects. We offer peer review services for reports prepared by other environmental consultants. This service is offered to fellow consultants seeking a second opinion for due diligence, clients who have collaborated with other consulting firms and government agencies and municipalities who need to supplement their in-house consulting resources.

Storage Tank Decommissioning

According to Ontario regulations, property owners are legally obliged to eliminate above and underground storage tanks that are no longer in use. This process demands a knowledgeable team, as improper removal could lead to a significant chemical spill, jeopardizing the property’s integrity and the surrounding environment.

Our company is experienced in the coordination and execution of locating storage tanks, safe removal procedures and addressing any potential contamination that may have stemmed from their presence.
