Notes (UPDATE PENDING) → Large map, may take a minute to load. Mostly relates to percussion drilling for groundwater – borehole logs, pump testing and chemical data – but also include rotary core drilling with detailed logs for geotechnical investigations.
This map shows more than 11 500 boreholes grouped into numbered circles. Click a circle to zoom in on that area. To go back out, use the − button on the map, or hold Ctrl and scroll the mouse wheel (on a phone, pinch with two fingers). The square button at the top right opens the map full screen.
