Warragul (Victoria) – Mercury

March 2012 – Warragul (Victoria) – Mercury 0.0012mg/L

All results below ADWG health guideline values with exception of mercury in Warragul WTP filtered water inlet to reservoir in March 2012 where a result of 0.0012mg/L was reported.No cause was identified for result All subsequent reticulation monitoring was compliant.

Mercury: Australian Drinking Water  Guideline 0.001mg/L

Mercury, if it enters the ecosystem can transform into the more toxic methylmercury where it can bioaccumulate. Methylmercury is highly toxic to human embryos, fetuses, infants and children. Mercury has numerous sources including old gold mines, where mercury was used in gold recovery process. It has been estimated that 950 tonnes of
mercury was deposited into Victorian soil, rivers and streams during the various gold rushes.

Warragul (Victoria) – Iron

2020/21: Warragul (Victoria) – Iron 0.48mg/L (max), 0.02mg/L (average)

Based on aesthetic considerations (precipitation of iron from solution and taste),
the concentration of iron in drinking water should not exceed 0.3 mg/L.
No health-based guideline value has been set for iron.

Iron has a taste threshold of about 0.3 mg/L in water, and becomes objectionable above 3 mg/L. High iron concentrations give water an undesirable rust-brown appearance and can cause staining of laundry and plumbing fittings, fouling of ion-exchange softeners, and blockages in irrigation systems. Growths of iron bacteria, which concentrate iron, may cause taste and odour problems and lead to pipe restrictions, blockages and corrosion. ADWG 2011
