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.

It searches on-site or well number only, i.e. SQ30541 for a surface water site or M36/1160 for a groundwater well.

If you don't know the site or well number, or for more advanced searches, you can view surface water sites or groundwater well sites.

Before using our water quality data, please read the Terms of Use (PDF File, 90KB).

Compare our results to the Ministry of Health Drinking-water information.
