Yarra Junction (Victoria)  – Lead

2006/2007: Yarra Junction Lead 0.006mg/L (max), 0.001mg/L (min.)

Lead Guideline reduced from 0.01mg/L to 0.005mg/L in June 2025. “The concentration of lead in water within premises may be higher, especially in older buildings, due to contact of the water with lead-containing plumbing products (enHealth 2021). A review found several Australian and international studies that detected up to 0.162 mg/L of lead in drinking water due to leaching from lead-containing plumbing materials including taps and lead service lines, suggesting that leaching of lead from lead-containing plumbing materials can be substantial (SLR 2023)… Based on health considerations, the concentration of lead in drinking water should not exceed 0.005 mg/L.”

Yarra Junction – Victoria – Turbidity

2007/08: Yarra Junction (Victoria) – Turbidity 21 NTU (max)

2010/11: Yarra Junction (Victoria) – Turbidity 5.6 NTU (Maximum detection during year)

2018/19: Yarra Junction (Victoria) – Turbidity 5.8 NTU (max), 2.7 NTU (95th percentile)

2020/21: Yarra Junction (Victoria) – Turbidity 120 NTU (max), 3.47 NTU (95th percentile)

2022/23: Yarra Junction (Victoria) – Turbidity 6.9NTU (max), 2.85 NTU (95th percentile)

Chlorine-resistant pathogen reduction: Where filtration alone is used as the water treatment
process to address identified risks from Cryptosporidium and Giardia, it is essential
that filtration is optimised and consequently the target for the turbidity of water leaving
individual filters should be less than 0.2 NTU, and should not exceed 0.5 NTU at any time
Disinfection: A turbidity of less than 1 NTU is desirable at the time of disinfection with
chlorine unless a higher value can be validated in a specific context.
Aesthetic: Based on aesthetic considerations, the turbidity should not exceed 5 NTU at the
consumer’s tap.

2007/08: Yarra Junction (Victoria) – Iron

2007/08: Yarra Junction (Victoria) – Iron 0.4mg/L (max)

2020/21: Yarra Junction (Victoria) – Iron 6.48mg/L (max), 0.05mg/L (min), 0.63mg/L (mean)

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
