About Environmental Services

Our Environmental Services group provides guidance and direction on all environmental matters associated with the acquisition, development, management and divestment of land.

In addition to procurement and management of a wide range of specialist environmental services, we deliver:

  • project management for the remediation for all Renewal SA projects including Bowden, Lot Fourteen and Tonsley
  • coordination and management of the environmental obligations in regards to disposal and acquisition of land
  • ensuring compliance with Renewal SA policies and procedures to maintain compliance with the Environment Protection Act 1993
  • and other relevant Acts with environmental components
  • project management for Renewal SA’s ongoing environmental commitments, such as groundwater monitoring, on sites like Our Port
  • advice to other government departments and agencies as required.

Other things we do include:

  • ensuring that sites are suitable for the proposed end use through the management of Site Contamination Auditors in accordance with the Environment Projection Act 1993
  • providing guidance on the suitability of fill on all Renewal SA sites
  • advising planners on environmental issues impacting rezoning and development applications
  • liaising with the Environmental Protection Authority
  • estimating costs for remediation of development sites.

Internally, we also offer guidance and direction on environmental communications with input into risk management strategies, community engagement and media responses.

Tonsley Village Environmental Management

As with any residential development on land that was not previously zoned residential land, Renewal SA has undertaken an environmental site contamination audit ahead of Peet Limited commencing development of Tonsley Village. The results of the Site Contamination Audit confirmed that the site is suitable for the residential development.

This environmental audit requires ongoing monitoring of the environmental conditions to ensure there are no unexpected changes. Renewal SA’s continued commitment under this environmental audit, including regular testing of ground water and soil vapour, is currently undertaken every year in accordance with the Auditor-endorsed, updated Environmental Management Plan (EMP).

The latest test results concluded that no additional actions are considered necessary and the risk profile has not changed.

For further information, please refer to the letter to residents or Environmental Monitoring.

Results and reports prior to May 2022 are available on request.

Clovelly Park and Mitchell Park Environmental Management Project – Phase 2

In 2015 Renewal SA entered into a Voluntary Site Contamination Assessment Proposal with the Environmental Protection Authority and has now completed environmental investigations in Clovelly Park and Mitchell Park.

Renewal SA entered into this Voluntary Site Contamination Assessment Proposal with the Environment Protection Authority (EPA) to carry out further investigations in the areas of Clovelly Park and Mitchell Park to determine the nature and extent of soil and groundwater contamination.

These investigations – Phase 2 – built upon those undertaken by the EPA in 2014, which indicated that further testing and assessment work was necessary to understand whether the groundwater plume extended north of Alawoona Avenue in Mitchell Park.

Phase 2 involved a series of investigations through 2015–2018 to:

  • provide additional information in relation to environmental conditions in the area;
  • assist with delineation of groundwater contamination north of Alawoona Avenue in Mitchell Park;
  • find the north-western extent of the groundwater contamination in the Mitchell Park/Marion area; and
  • confirm that the contamination previously reported in this area had not changed, while better defining the extent of the contamination.

The investigations have also involved:

  • the installation of several new groundwater wells in Mitchell Park and Marion, to assist in better defining the north western extent of the groundwater contamination;
  • a risk assessment in slab on ground and crawl space homes from vapour potentially rising up through the soil from groundwater – which did not identify any health risk to residents; and
  • a basement survey in targeted areas of Mitchell Park with no basements identified, thus confirming the earlier assessment of risk.

Interim Audit Advice was produced by the independent Site Contamination Auditor confirming that groundwater contamination in the area has been delineated. The auditor also concluded that the risks to residents in the notification area do not exceed the acceptable levels set by the EPA. The auditor agrees with earlier advice to the community not to use bore water for any purpose.

The Site Contamination Audit has now been completed with the audit statement and report submitted to the EPA in April 2020.

The conclusions of the audit confirm those of the Interim Audit Advice and no further work is planned by Renewal SA.
