Groundwater Quality Restricted Use Zones (GQRUZ) are areas where there has been historic groundwater pollution as a result of previous industrial or other activities. These zones have been subject to cleanup in line with the relevant environmental standards. However, restrictions remain on what the water can be used for if it is extracted via a groundwater bore.
GQRUZ do not represent a comprehensive list of all sites where groundwater quality may not be suitable for use. Rather, they represent locations where EPA has formally recognised that groundwater is polluted, following site investigations under EPA's environmental audit program. Other sources of information on groundwater quality include EPA's Priority Sites Register, which lists sites which are currently undergoing clean-up under EPA's compliance and enforcement activities.
This dataset is in spatial format and contains a map of GQRUZ across Victoria.
