A PESA is a study of the past and present land uses of a parcel of land or a site.  The PESA will establish whether the site has any potential for soil or groundwater contamination.  A PESA is required to be performed as part of regulatory compliance as directed by local council or Victorian EPA, site rezoning or redevelopment requirements for property purchase or divestment.

Typical activities undertaken as part of a PESA include:

  • Site history review to determine past and current land uses.
  • Site walkover survey to determine potential sources of contamination eg; presence of an underground storage tank, above ground storage tank, chemical store areas, visual staining on soil surface etc.
  • Site characterisation via collection of relevant site specific information including geological and hydrogeological information, surrounding land uses, etc.
  • Development of a preliminary site specific conceptual site model to detail potential pollutant linkages present at the site.
  • Limited soil sampling for identified potential contaminants of concern via borehole drilling, hand augering and test pitting sampling methods.
  • Analysis of all data obtained during the assessment and compilation of an appropriate PESA report, detailing environmental quality of the soil with respect to future site users and environment.

A.S.James’ team of environmental consultants can individually tailor a scope of works for a PESA to suit a client’s requirements and budget.

A.S.James’ environmental site assessments are performed in accordance with Victorian legislation and state policies, Victorian EPA guidelines and National Environment Protection (Assessment of Site Contamination) Measure.
