Bore construction

Bore water testing

There is no legal water quality testing needed for private water bores.

It is up to you to keep track of your water quality.

You should test water quality after bore construction, before the water is used, and each year after that.

Tests for bacteria, nitrate and trace metals should be done by a NATA-accredited water analysis laboratory.

If you are operating a business that provides drinking water you must make sure the water is safe to drink.

Environmental Health provides information on its how to manage private water supplies page.

Test for trace metals

If you are taking water from an aquifer which includes black shale, you should test your bore for trace metals - including arsenic.

Black shale can be naturally mineralised with heavy metals.

Darwin rural area bores that have black shale are:

  • Whites formation Acacia Hills - part of the Mount Partridge groundwater system
  • Burrell Creek formation, South Alligator.

Find out which groundwater resource your bore is likely to be taking water from. Use the know your bore tool on the Department of Natural Resources website.
