Water quality data
We manage an extensive database of water quality sampling results. The results primarily relate to samples collected by us, but also include results from external parties.
Our water quality search displays a summary of sampling details and results, which can be downloaded or printed. There may be a delay in publishing data by up to 3 months after the sampling date to allow quality checks to take place. It searches on-site or well number only, i.e. SQ30541 for a surface water site or M36/1160 for a groundwater well.
Compare our results to the Ministry of Health Drinking-water information.
