Identification and Assessment of Contaminated Land

​​​​​​Contaminated site assessment involves a staged process of investigation and risk assessment undertaken by suitably qualified and experienced consultants. EPA Tasmania provides a list of potentially contaminating activities and the property information request service to assist with site history reviews. EPA Tasmania also supports the planning process, which requires sites to be suitable for their intended use, by providing an assessment report review service for planning authorities where a site with a history of contamination is changing to a sensitive use.​

Potentially contaminated land means land which could have been contaminated by a potentially contaminating activity (PCA) which is currently occurring or was historically hosted on the land or adjacent land. The potential for contamination to create a risk is dependent on the nature of the chemical substances used in the activity, the reactions and by-products from such substances, the extent and concentrations present on the land and on the nature of the proposed use and development.

Accordingly, it is important to proceed through a staged process of assessment in order to determine the nature and extent of contamination and the associated risks to human health and the environment.

  • Potentially Contaminating Activities, Industries and Land Uses
    A list of potentially contaminating activities, industries and land uses which may have caused soil and/or groundwater contamination resulting in the land being a contaminated site.
  • Contaminated Land and the Planning Process
    Contaminated site assessments, remediation and/or management may be required in order to demonstrate, to the satisfaction of a Planning Authority, that land is suitable for an intended use where there is: the consideration of re-zoning or change of land use to a more sensitive use, or the development may cause the creation of an exposure pathway and an unacceptable risk to human health and/or the environment. EPA Tasmania offers the Site contamination sign-off process to assist in this process.
  • Contaminated Site Assessment
    A contaminated site assessment is a formal, scientific evaluation of the nature and extent of contamination on- and off-site and an assessment of the actual or potential risk to human health or the environment resulting from that contamination. The assessment is undertaken in a staged approach based on the development of conceptual site models and risk assessments.
  • Engaging a Contaminated Site Assessment Consultant
    Engaging professionals who have the relevant qualifications, competencies and experience is important. Contaminated site assessments are inherently complex and usually present a wide range of issues requiring a multi-disciplinary approach, including scientific, technical and project management skills. Assessments must also meet relevant standards, quality assurance and regulatory requirements.
  • Property Information Request (PIR)
    People can request a search of EPA databases to determine if potentially contaminating activities have or are occurring on a site.
