Australian Drinking Water Map

Yalata (South Australia) Lead

9 October 2013 – Yalata (South Australia) – Lead 0.0169mg/L

22/7/24: Yalata Lead 0.0076mg/L

Lead Australian Drinking Water Guideline 0.01mg/L

“… Lead can be present in drinking water as a result of dissolution from natural sources, or from household plumbing systems containing lead. These may include lead in pipes, or in solder used to seal joints. The amount of lead dissolved will depend on a number of factors including pH, water hardness and the standing time of the water.

Lead is the most common of the heavy metals and is mined widely throughout the world. It is used in the production of lead acid batteries, solder, alloys, cable sheathing, paint pigments, rust inhibitors, ammunition, glazes and plastic stabilisers. The organo-lead compounds tetramethyl and tetraethyl lead are used extensively as anti-knock and lubricating compounds in gasoline…ADWG 2011

Yalata (South Australia) – Iron

11 September 2012: Yalata (South Australia) Iron 0.5206mg/L

19 August 2013: Yalata (South Australia) Iron 0.5531mg/L

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

2017 – Yalata – Sodium

21 February 2017: Yalata (South Australia) – Sodium 197mg/L

“Based on aesthetic considerations (taste), the concentration of sodium in drinking water
should not exceed 180 mg/L….The sodium ion is widespread in water due to the high solubility of sodium salts and the abundance of mineral deposits. Near coastal areas, windborne sea spray can make an important contribution either by fallout onto land surfaces where it can drain to drinking water sources, or from washout by rain. Apart from saline intrusion and natural contamination, water treatment chemicals, domestic water softeners and
sewage effluent can contribute to the sodium content of drinking water.” ADWG 2011
 

2017 – Yalata (South Australia) – Total Dissolved Solids

February 2017 – March 2017: 1725mg/L (average from 2 detections. Two above ADWG)

GUIDELINE

“No specific health guideline value is provided for total dissolved solids (TDS), as there are no
health effects directly attributable to TDS. However for good palatability total dissolved solids
in drinking water should not exceed 600 mg/L.

Yalata (South Australia) Manganese

27/2/24: Yalata (South Australia) Manganese 0.1703ug/L (max), 0.0431ug/L (av. 2023/24)

“Based on health considerations, the concentration of manganese in drinking water should not exceed 0.1 mg/L

Based on aesthetic considerations, the concentration of manganese in drinking water should not exceed 0.05 mg/L, measured at the customer’s tap. Water authorities are encouraged to keep manganese concentrations as low as possible, preferably below 0.02 mg/L at the treatment plant…

Reviews by the World Health Organization (WHO) and Health Canada found that several human epidemiological studies suggest an association between exposure to manganese in drinking water and neurological effects (e.g. intellectual impairment and poorer neurobehavioural function, including memory, attention, motor function and hyperactivity). Although these epidemiological studies could not establish the level at which oral manganese intake can lead to neurotoxic effects, collectively they provide support that neurotoxicity is a critical effect in humans (WHO 2021; WHO 2022; Health Canada 2019).

Infants, especially newborns, are unable to regulate the levels of manganese in their bodies due to greater gastrointestinal absorption and immaturity of their homeostatic control of bile excretion (i.e. they excrete less manganese) and are more susceptible than other age groups to the neurotoxic effects of excess manganese (WHO 2021; WHO 2022; Health Canada 2019).

Bottle-fed infants may also be at risk of higher manganese exposure due to infant formula which can be fortified with manganese, along with drinking water used to reconstitute the formula which can have elevated manganese levels compared to bottled water (WHO 2021; WHO 2022; Health Canada 2019).
