Clovelly Park and Mitchell Park Environmental Management Project – Phase 2
Renewal SA has entered into a Voluntary Site Contamination Assessment Proposal with the Environmental Protection Authority to carry out further investigations at Clovelly Park and Mitchell Park.
In 2015, Renewal SA entered into a 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 – build upon those undertaken by the EPA in 2014, which indicated that further testing and assessment work was necessary to understand whether the groundwater plume extends north of Alawoona Avenue in Mitchell Park.
The Phase 2 investigations occurred during the latter half of 2015 and provided additional information in relation to environmental conditions in the area. In June 2016 several new groundwater wells were installed in Mitchell Park to assist with delineation of groundwater contamination north of Alawoona Avenue in Mitchell Park. Results from the testing of the new wells revealed Trichloroethene (TCE) concentrations similar to the 2014 EPA assessment results, undertaken by the EPA in the area immediately south of Alawoona Avenue.

In early August 2016 Renewal SA advised the local community that a further nine groundwater wells would be installed in areas of Mitchell Park and Marion to undertake further investigations (refer to the letter to residents, August 2016, following).
These 2016 investigations were carried out to find the north-western extent of the groundwater contamination in the Mitchell Park/Marion area. A subsequent risk assessment did not identify any health risk to residents in slab on ground or crawl space homes from vapour potentially rising up through the soil from the groundwater.
Further investigations between November 2017 and April 2018 confirmed that the contamination previously reported in this area has not changed, although its extent is now better defined. A basement survey was undertaken in targeted areas of Mitchell Park with no basements identified thus confirming the earlier assessment of risk.
Interim Audit Advice has been produced by the independent Site Contamination Auditor confirming that groundwater contamination in the area has been defined. The Auditor also concluded that the risks to residents in the notification area do not exceed the acceptable levels set by EPA. The Auditor agrees with earlier advice to the community not to use bore water for any purpose.
A copy of the Interim Audit Advice (the final deliverable required from Renewal SA by the EPA under the current VSCAP agreement) along with the Community letter is available to download following. An electronic copy of the December 2018 report appendices can be requested by emailing email@example.com.

Ash Avenue and Chestnut Court Clovelly Park: proposal to develop a temporary open green space for community use in Ash Avenue and the interim management of the vacant land
The results of the community engagement process has been summarised in a draft report prepared by Renewal SA and provided to Marion Council. This report summarises the findings and recommendations drawn from community feedback and will assist and inform the final decisions.
The option identified through the consultation as the most favoured for the temporary open green space for community use was Option 3 (details available in report). Renewal SA is preparing a detailed plan for this option and will liaise with Marion Council in making the final decision on the preferred option.
Note that no final commitments have been made about the Chestnut Court play space, which will first require a decision from council.
Residents in the area of Clovelly Park south of Ash Avenue have been advised by letter.
For further information please refer to the letter (June 2016) and report (following), or visit the Marion Council’s Making Marion website.
