Environmental Monitoring
We monitor the health of rivers, streams, estuaries and the coast through a variety of monitoring programmes
This information helps to assess the state of our environment, to identify where further actions are required to improve water quality or ecosystem health and where further investigation is required. It also helps determine the effectiveness of our regional policies and plans and contributes to national environmental reporting.
State of the Environment
Nelson City Council’s Science and Environment unit has released its latest State of the Environment Report. The report provides crucial insights into our local environment and serves as a vital resource for understanding its current state and guiding future initiatives aimed at fostering a sustainable and healthy community.

River water quality and ecology monitoring reports
Overview Nelson’s river water quality and ecology monitoring programme provides information on the stream health across the five Freshwater Management Units. Water quality and ecosystem health are currently monitored at 27 State of Environment (SOE) sites. These sites were chosen to represent the geographic nature and major land uses across the region. Additional monitoring sites for targeted water quality investigations are also reported on here using National Policy for Freshwater Management (NPS-FM 2020) attributes.
Recreational bathing water quality monitoring report
Bacteria levels are monitored by Nelson City Council across six river and five marine recreation bathing sites over summer. This monitoring reporting is used to identify risks to public health from disease-causing organisms and toxic algae. People can then make informed decisions about where, when, and how they use rivers and the marine environment for recreation to minimise the risk of illness from harmful waterborne pathogens that may be present.
