Groundwater Prohibition Areas (GPA)
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 (GPA).
A groundwater prohibition area information sheet has been prepared to describe the health-based criteria and other considerations the EPA applies when determining the need to implement a GPA.
The purpose of this initiative is to protect both current and future landholders from accessing the contaminated groundwater. Future purchasers of properties within this area are made aware via sale documentation on the Form 1 statement which is provided to a prospective buyer.
When this occurs the EPA commences a community engagement process in relation to establishing a GPA. Residents have a consultation period in which they can meet with staff, have questions answered, and raise any concerns. Subject to the outcome of this consultation a notification will then be made in the SA Government Gazette and a maximum fine of $8,000 may be issued to persons using bore water at their property.
Rainwater and mains water (tap water) are not affected by this issue and home-grown fruit and vegetables are safe to consume, provided they are not being watered with bore water.
