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.

River water quality water is valued for many reasons including ecological function and habitat, recreational value, its role in supporting people and industry, and its cultural significance. Nutrients such as nitrogen and phosphorus are essential for plant growth, however too much in rivers can lead to ‘nuisance’ growths of river algae and aquatic plants, degrading habitat. High concentrations in the form of ammoniacal nitrogen and nitrate-nitrogen can be toxic to fish and other aquatic animals. Water clarity is a measure of underwater visibility, and affects habitat of aquatic life such as fish and birds, and can also impact on aesthetic values and recreational use of rivers and streams.

Trend statistics and calculation results for the periods 1989-2013, 1994-2013, and 2004-2013 are provided by monitored site. Units for parameters are mg/m3, except CLAR (m). Refer to Larned at al. 2015 for further details.

Escherichia coli (E.coli) can indicate the presence of pathogens (disease-causing organisms) from animal or human faeces, which can cause illness.

File contains raw data collected at NIWA monitored sites of the National River Water Quality Network (NRWQN) over the period 1989-2013. The NRWQN network is used to calculate national trends in river water quality. Fields are described as follows. Refer to Larned et al. 2015 for further details:
sID ---- Unique site ID
srcid ---- Region site is located in
sflag ---- River (r) or Estuary (e)
river ---- River name
location ---- Name of site
nzmge ---- easting
nzmgn ---- northing
NZReach ---- REC1 segment identifier
sDate ---- sample date
Q ---- Recorded flow when sample was taken, cumecs
npid ---- NIWA parameter ID (as used in Larned et al. 2015)
values ---- Parameter value (units are mg/m3, except CLAR (m) and ECOLI (n/100 mL))
