Tonsley and surrounding areas

Tonsley proposed groundwater prohibition area.

The EPA is proposing to establish a groundwater prohibition area in Tonsley and portions of Clovelly Park, Mitchell Park and Marion. These suburbs have a proud manufacturing history, with some past chemical disposal and handling practices having contaminated the groundwater.

If contaminated groundwater is a risk to human health, the EPA has the ability under the Environment Protection Act 1993 to establish a groundwater prohibition area. The purpose is to protect both current and future landholders from accessing the contaminated groundwater.

    The EPA has established groundwater prohibition areas in several areas of metropolitan Adelaide. Community engagement has informed their establishment, and in some instances has changed the depth and breadth of the prohibition.

    Community engagement with the EPA is ongoing, and we encourage you to please get in contact with us during this time. We are especially keen to hear from existing bore users, whether your bore is registered or unregistered.

    We are available over the phone and online and encourage you to please call or email us, either during or outside of business hours.

    • Phone: (08) 8204 2004
    • Email: engage.epa@sa.gov.au
    • On this site: interactive map, Q&A, 'How you would like to be engaged' poll, and register to stay informed
    • Video conference or in person: please contact us to make arrangements

    Rainwater and mains water (tap water) are not affected by groundwater contamination.

    Home-grown fruit and vegetables are safe to consume, provided you are not watering them with bore water.

    Sites that were formerly industrial may have further restrictions that you should be aware of. Please see the Form 1 Statement that was provided to you at the time of purchase, or contact the EPA if you would like to find out more information.

  • Please do not use your bore water

    Groundwater (bore water) in the upper 2 aquifers is contaminated and should not be used for any purpose. The depth of the known contamination extends from 0–25 m below ground level. Deeper aquifers used by schools and councils are not affected.

    Health problems can occur if people come into contact with the contaminated water over a long period of time. The contamination presents a potential risk to human health if groundwater is utilised for drinking, showering, washing, filling swimming pools, watering lawns or irrigating edible produce.

    Groundwater from bores in this area should also never be used to wash down paths or driveways, or even as grey water for toilet flushing. Preventing the extraction of contaminated groundwater is necessary to protect human health and prevent the spread of contamination.
