When you want to know the differences between environmental assessment phases 1 and 2, the below-given information will be useful.

The report called Environmental Site Assessment (ESA) is prepared and created for real estate property and holdings. It establishes the existing as well as potential environmental and contaminations related to it. The physical modifications and improvements, along with the underlying land, are inspected. Some of the common contaminants include asbestos and materials containing it, inventories of hazardous materials and substances that might have been stored in the area, items containing lead (including paint), mould, mildew, and others. Elaborate tests are carried out in ESA Phase 2. When you want to know the differences between environmental assessment phases 1 and 2, the below-given information will be useful.

ESA Phase 1

Phase 1 ESA in Edmonton is generally considered to be the very first step and stage of the assessment process. When ESA Phase 1 finds out and categorically approves, that specific contaminants affect a property; the ESA phase 2 may be carried out to have more definitive and explicit details. Some of the essential inclusions of Phase 1 ESA in Edmonton


The visual inspections of the current state of a property or site and its comparison with the existing building plans

Search and review the existing records about the property to determine whether it has been used for storing hazardous substances. Public records, libraries, and databases of other origins can be searched for and explored to obtain information and reach conclusions.

A visual inspection of the properties surrounding the main property to ensure that any contamination is not transferred to the site from nearby areas

Imageries as well as conduction of interviews involving government officials, auditors, property owners of nearby sites, occupants, and operators

ESA Phase 2

Phase 2 of ESA is also called a subsurface investigation. It is a more intrusive investigation, which involves the collection of samples from the existing building materials, water bodies, and soil, which are investigated further in a laboratory for contamination. As said earlier, Phase 2 is carried out when Phase 1 determines that contaminants are present in the property. Some of the materials and substances commonly tested during Phase 2 include petroleum substances and products, asbestos, solvents, pesticides, heavy metals, and moulds, among others. Boring is done and placed for finding out contamination in water and soil. Sample analysis and laboratory/pilot test studies are carried out, which provides essential information and results in critical areas. Nowadays, computer modelling is also used for determining the characteristics of a property and site. Another crucial aspect of Phase 2 is that the tests’ results are also compared with the regulatory guidelines issued by the federal and state governments for ensuring compliance.

Apart from environmental assessment phase 1 and 2, there is also a phase III of environmental assessment, which includes the remedial actions. Logistics and cost are considered before the more effective and economic corrective and cleanup actions are suggested.

ESA is a part of the due diligence process. It is crucial to engage a leading and licensed consultancy and ESA service provider to ensure the test results’ reliability. Following the ASTM and other relevant standards may be quite crucial, as it is a requirement set by many lenders as well.
