Check Your Groundwater Areas (CYGA) are areas where there has been historic groundwater pollution as a result of previous industrial or other activities. They were previously called Groundwater Quality Restricted Use Zones (GQRUZ). CYGAs are either currently being investigated or have been subject to clean up in line with the relevant environmental standards. However, the water needs to be checked before using it as it may be unsuitable. A CYGA remains during investigating extent of groundwater impacts and when attempts have been made to clean up the groundwater at the affected site, but full clean-up was not possible - as it is often difficult to remove 100 per cent of groundwater pollution. It also may be impractical to clean up groundwater to the level needed to restore it to its original condition. EPA then identifies that groundwater in the area should be checked to determine if it is suitable for use. CYGA 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. 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. Every effort has been made to ensure the accuracy of the CYGA data published. EPA will not be held liable or responsible for any errors, or for any loss incurred from reliance on this data. This dataset mirrors the CYGA data available on EPA's website interaction portal, but may not be up to date due to data transfer processes.

The Priority Sites Register (PSR), maintained by EPA and publicly available since May 1990, is a current EPA service providing a list to the public. PSR is a list of sites in Victoria, where EPA has issued a notice requiring active management to clean up, monitor, or prevent pollution of land and/or groundwater contamination, specifically:  Under the Environment Protection Act 1970: Clean Up Notice (related to land and groundwater) pursuant to section 62A  Pollution Abatement Notice (related to land and groundwater) pursuant to section 31A or 31B  Under the Environment Protection Act 2017 Improvement Notice (related to land and groundwater) pursuant to Section 271  Prohibition Notices (related to land and groundwater) pursuant to Section 272  Environment Action Notice (related to land and groundwater) pursuant to Section 274  Site Management Order (related to land and groundwater) pursuant to Section 275   Typically, these are sites where contamination of land and/or groundwater presents an unacceptable risk to human health or to the environment. The condition of these sites is not compatible with the current or approved use of the site without active management to reduce the risk to human health and the environment. The priority sites data provides information about all current/active priority sites. Once a site has complied with notices it is removed from the PSR list. The PSR does not list all sites that are known to be contaminated in Victoria. A site should not be presumed to be free of contamination just because it does not appear on the PSR.

EPA maintains a searchable list of sites or properties with a Preliminary Risk Screen Assessments issued in accordance with Section 204 of the Environment Protection Act 2017. Preliminary risk screen assessments (PRSAs) look for possible land contamination. PRSAs relate to a site’s existing or proposed future use. PRSAs don’t replace environmental audits, they work out whether there’s a need for an Environmental Audit recommend the scope for the environmental audit if it’s required. This dataset mirrors the PRSA data available on EPA's website, but may not be up to date due to data transfer processes. For the most up to date data, go to EPA's website public register page.

EPA maintains a searchable list of sites or properties issued with a certificate or statement of environmental audit in accordance with 53X of the Environment Protection Act 1970, and sites with a audit issued in accordance with section 53V of the Environment Protection Act 1970. EPA also maintains a searchable list of sites and properties issued with a statement of environmental audits issued in accordance with section 208 of the Environment Protection Act 2017. Since the 1st of July 2021, the notification of new 53X and 53V audits under the Environmental Protect Act 1970 ceased and all environmental audits since this date have been notified under section 208 Environmental Protection Act 2017. The types of audits notified under the Environmental Protection Act 2017 include, Land Suitability Audits which most commonly take place when land is proposed for new use and is potentially contaminated, or if it is already covered by an Environmental Audit Overlay. Risk of Harm from an activity audits which are related to sites with EPA permissions or licences, Risk of Harm from Contaminated Land, Pollution or Waste Audits which are mostly related to EPA notices relating to clean up of pollution or waste on sites. This dataset mirrors the audit data available on EPA's website interaction portal, but may not be up to date due to data transfer processes. For the most up to date data, go to EPA's website public register page.

A CYG area is an area or precinct where EPA knows groundwater has been contaminated by: • an activity • waste • pollution • contaminated land. CYG areas are where contaminant levels threaten one or more environmental values. The groundwater in a CYG area may not be suitable for some uses. It may be harmful to human health and the environment. It's important for anyone who wants to use groundwater in CYG areas to test it to make sure it's safe to use. Each CYG area has a status to help you understand how much groundwater investigation and clean-up has been done. EPA assigns a CYG area one of 3 statuses: 1. Post remediation – clean-up of groundwater has been done, but some groundwater contamination remains. All former groundwater quality restricted use zones (GQRUZs) have this status. 2. Under assessment – further monitoring, evaluation and/or remediation of the groundwater is expected. 3. Precinct – the source of groundwater contamination is not clear. There's evidence it comes from multiple sites. Clean-up of the groundwater cannot be effectively completed. When a particular area is not captured by a CYG area, it does not mean that the groundwater there is suitable for use. The groundwater may not have been tested. Every effort has been made to ensure the accuracy of the CYG area data published. EPA will not be held liable or responsible for any errors, or for any loss incurred from reliance on this data. For further information about a particular CYG area, refer to the accompanying assessment report (where available) or contact EPA.

EPA Victoria Victorian Landfill Register (VLR) - Location Points The Victorian Landfill Register created by EPA in 2018 lists all current and known closed landfills in Victoria and creates a strong foundation for building a complete and comprehensive landfill register for Victorians. Landfills can cause contamination, but once a landfill is closed, operators are obliged to rehabilitate and manage their sites. Even when closed, careful management of sites is required. Many rehabilitated landfills are now safe parks and public spaces, enjoyed by the community. The register draws information from various sources and all sites listed undergo verification before inclusion on the register. While this public register will make landfill information more available, it should not be used as the only source of information when making important decisions. EPA will continue to build on the register, adding information and improving the service. This dataset mirrors the VLR data available on EPA's website, but may not be up to date due to data transfer processes. For the most up to date information on operating landfill please visit the EPA register of permission.
