This dataset was first added to MfE Data Service on 15 Apr 2019.

This dataset contains ten parameters of water quality based on measurements made at monitored river sites:

- Nitrate-nitrogen
- Ammoniacal nitrogen
- Ammoniacal nitrogen (adjusted)
- Total nitrogen
- Total phosphorus
- Dissolved reactive phosphorus
- Water clarity
- Turbidity
- Escherichia coli
- Macroinvertebrate community index

This dataset includes:

- Median values for the period 2013 to 2017
- for selected indicators, how these values compare to the National Objectives Framework (NOF) (MfE, 2017) bands related to ecosystem health and human health for recreation, and to expected concentrations in natural conditions, as shown by the default guideline values in the Australian and New Zealand guidelines for fresh and marine water quality (ANZG, 2018)

More information on this dataset and how it relates to our environmental reporting indicators and topics can be found in the attached data quality pdf.
