EPA Victoria Groundwater Quality Restricted Use Zones (GQRUZ)

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.\r\n\r\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.\r\n\r\nThis dataset is in spatial format and contains a map of GQRUZ across Victoria.

地下水质量限制使用区（Groundwater Quality Restricted Use Zones，GQRUZ）是指因过往工业或其他活动造成历史性地下水污染的区域。此类区域已按照相关环境标准开展污染治理，但通过地下水钻孔抽取的地下水在使用用途上仍存在限制。

GQRUZ并非涵盖所有地下水水质不适宜使用场地的完整清单。实际上，它们仅为经环境保护局（Environmental Protection Authority，EPA）依据其环境审计计划开展场地调查后，正式认定存在地下水污染的点位。其他可获取的地下水水质信息来源包括EPA的优先场地登记册，该登记册收录了当前正依照EPA的合规与执法行动推进污染治理的场地。

本数据集采用空间格式，包含维多利亚州范围内的GQRUZ分布图。
