Water quality data

We manage an extensive database of water quality sampling results. The results primarily relate to samples collected by Environment Canterbury. But also included are results provided by 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 do not know the site or well number or for more advanced searches, you can use Canterbury Maps Viewer.

Before using Environment Canterbury’s Water quality data, please read the Terms of Use (PDF File, 90KB).
