NSW Office of Water groundwater quality bores - Namoi

## **Abstract** \n\nThe dataset was derived by the Bioregional Assessment Programme from the Namoi water quality dataset. The source dataset is identified in the Lineage field in this metadata statement. The processes undertaken to produce this derived dataset are described in the History field in this metadata statement.\n\n\n\nThis is a subset of the Namoi water quality data provided by the NSW Office of Water, clipped to the Namoi subregion.\n\n\n\nThe NSW Office of Water (NoW) provided water quality data for the Namoi region. The data includes continuously monitored sites and discrete monitored sites. Sites with a GW prefix represent groundwater sites. Groundwater sites can be linked to their locational information through the NSW NGIS (provided by the Bureau of Meteorology).\n\n\n\nRefer to the source data for more information.\n\n## **Purpose** \n\nThis data was used to develop the NAM 1.5 product.\n\n## **Dataset History** \n\nThe source data was the groundwater quality information from the NSW Office of Water. Data outside of the Namoi subregion was deleted and the data then clipped to only show results post-1970 for data quality purposes. Only the most recent measurement from each bore was used. The data was categorised according to groundwater salinity (EC) from the ANZECC water quality guidelines.\n\n## **Dataset Citation** \n\nBioregional Assessment Programme (2015) NSW Office of Water groundwater quality bores - Namoi.

## **摘要**

本数据集由生物区域评估计划（Bioregional Assessment Programme）基于纳莫伊水质数据集衍生所得。源数据集的相关信息详见本元数据声明的「谱系（Lineage）」字段，本衍生数据集的生成流程则收录于「历史（History）」字段。

本数据集为新南威尔士州水务局（NSW Office of Water）提供的纳莫伊水质数据的子集，已裁剪至纳莫伊子区域范围内。

新南威尔士州水务局（NSW Office of Water，简称NoW）为纳莫伊区域提供了水质数据，数据涵盖连续监测站点与离散监测站点两类。前缀带有GW的站点代表地下水监测点，此类站点的位置信息可通过澳大利亚气象局（Bureau of Meteorology）提供的新南威尔士州国家地理信息服务（NSW NGIS）获取。

如需获取更多详细信息，请参阅源数据集。

## **用途**

本数据集用于开发NAM 1.5产品。

## **数据集历史**

源数据为新南威尔士州水务局提供的地下水水质信息。为保障数据质量，已剔除纳莫伊子区域外的所有数据，并仅保留1970年之后的监测结果；同时仅采用每个钻孔的最新一次测量值。本数据集依据澳大利亚与新西兰环境保育委员会（ANZECC）水质指南中的地下水盐度（电导率EC）标准完成分类。
