Our latest data collected
The Christchurch Harbour & Marine Society regularly monitors E. Coli, phosphate and nitrate levels at three locations across the Rivers Stour and Avon as they flow into Christchurch Harbour.
The data below represents our latest test results and is published to help raise awareness of water quality conditions within the harbour catchment. Samples are collected and analysed using calibrated, certified equipment, with all results recorded and calculated carefully by our volunteer team.
While every effort is made to ensure accuracy, these results should be regarded as indicative and are shared in good faith based on the information available at the time of testing. Environmental conditions can change rapidly, and readers should interpret the data accordingly.
