EPA Victoria Groundwater Quality Restriction Use Zones (GQRUZ) - Location Points

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 clean up 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.\n\nA GQRUZ remains 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 restrictions that should remain on how the water can be used without further treatment.\n\nGQRUZ 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.\n\nEvery effort has been made to ensure the accuracy of the GQRUZ data published. EPA will not be held liable or responsible for any errors, or for any loss incurred from reliance on this data. Further information about a GQRUZ can be found in the audit report for the selected site.\n\nThis dataset mirrors the GQRUZ data available on EPA's website interaction portal, but may not be up to date due to data transfer processes.

地下水质量限制使用区（Groundwater Quality Restricted Use Zones，GQRUZ）是指因过往工业活动或其他行为引发历史性地下水污染的区域。此类区域已依据相关环境标准开展污染治理，但通过地下水钻井抽取的地下水，其使用用途仍受限制。

若受污染场地已尝试开展地下水治理，但因难以完全清除全部地下水污染物，或难以将地下水修复至原始水质标准而无法实现全面治理，则该区域仍会被划定为GQRUZ。此时美国环境保护署（Environmental Protection Agency，EPA）将明确需保留的、未经进一步处理即可适用的地下水使用限制要求。

GQRUZ并非涵盖所有地下水水质不适宜使用的场地的完整清单，仅代表美国环境保护署依据其环境审计项目开展场地调查后，正式认定存在地下水污染的区域。其他地下水水质相关信息来源包括EPA的优先场地名录（Priority Sites Register），该名录收录了目前正在EPA合规与执法活动框架下开展污染治理的场地。
