Water quality

Water can contain a variety of natural mineral salts depending on where it has been abstracted from. We ensure that potential contaminants are removed from your drinking water. The table below shows the average values from samples taken over the last financial year for your postcode area.

Table acronyms: ADWG = Australian Drinking Water Guidelines; PHR = Public Health Regulation.
