Blue staining on sinks and tiles can be an indication of copper leaching from the household plumbing and is normally due to an acidic water supply.

Acidic water typically occurs in low pH private bores and rainwater supplies whereas scheme water is treated to ensure the pH is Alkaline (above pH 7) minimising plumbing corrosion and the ingestion of metals.
