Preliminary Site Investigation (PSI) Stage I
Environmental Assessment

A PSI Stage I Environmental Assessment determines the likelihood that the property’s current or previous operations may have contaminated the site. The investigation includes:

  • A review of historical site use and records
  • A site visit with visual inspection of the property including equipment, buildings and adjacent surroundings
  • Interviews with any party that has been associated with the property including former owners, neighbors and government officials

There are a number of ways that a property can become contaminated (historical use, underground storage tank, neighbouring properties etc).  If there is a likelihood of contamination JOMA’s Environmental Assessment Report will indicate Areas of Potential Environmental Concern (APEC) and Potential Contaminants of Concern (PCOC). The report will also recommend that the property in question should undergo a more thorough inspection in the form of a PSI Stage II Environmental Site Assessment.

Preliminary Site Investigation (PSI) Stage II
Environmental Assessment

A PSI Stage II determines the location and the extent of the contamination (if present) through sampling of relevant environmental media (soil/water). A qualified environmental professional will take the appropriate samples that will then be analysed at an accredited laboratory. If contamination is present a Detailed Site Investigation is recommended.

In short, the main purpose of the PSI Stage II Environmental Site Assessment is to confirm or confute the potential risk of contamination found in the PSI Stage I.
