Groundwater quality

We monitor groundwater quality four times a year at 71 sites throughout the region. We measure a range of variables (including nutrients, trace elements and E. coli bacteria) to determine if the groundwater is suitable for drinking or other uses.

Check out our environmental reports for more information.

Groundwater levels

We measure groundwater levels at 146 sites across the region. Water levels at some of these sites are monitored continuously with the data logged on a regular basis (usually every 15 minutes) and then uploaded to our database via radio or cell phone transmission every 2 to 3 hours.

The data we provide for this website is a combination of raw (unchecked) and archived (checked) data. The archived data is shown in black and the raw data is shown in red. If you require the information in a form other than how it is presented here, please contact us and we can usually provide it within two working days.

Every quarter we publish summaries of the information collected to give a general picture of recent trends.

Check out our environmental reports for more information.
