Namoi NSW Office of Water groundwater EC (sampled post 1970)

Abstract

The dataset was derived by the Bioregional Assessment Programme from multiple source datasets. The source datasets are 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.

The aim of this data set was to be able to map the salinity (EC) of groundwater bores in the Namoi sub-region.

This has been clipped to the Namoi sub-region but not the Namoi PAE. The data set was clipped to post-1970 to avoid potentially imprecise values.

The data set is an extract of all groundwater quality measurements from groundwater bores that fell within the data management acquisition area as provided by BA to NSW Office of Water. The salinity (EC) was categorised according to the groundwater use categories and aggregated into the following categories: 'Drinking' (up to 1500 uS/cm), 'irrigation' (1500 uS/cm - 7999 uS/cm), 'livestock' (8000 uS/cm - 19999 uS/cm) and '>20,000 uS/cm'.

Purpose

This data set was derived to complete the water quality section of Product 1.5 for the Namoi Bioregional Assessment

Dataset History

The data set is an extract of all groundwater quality measurements from groundwater bores that fell within the data management acquisition area as provided by BA to NSW Office of Water.

This has been clipped to the Namoi sub-region but not the Namoi PAE. Data (EC) pre-1970 was deleted from the original data set to avoid potentially imprecise values.

The salinity (EC) was categorised according to the groundwater use categories and aggregated into the following categories: 'Drinking' (up to 1500 uS/cm), 'irrigation' (1500 uS/cm - 7999 uS/cm), 'livestock' (8000 uS/cm - 19999 uS/cm) and '>20,000 uS/cm'.
