28/05/2019: Murputja Fluoride 3.0 mg/l

27/8/19: Murputja Fluoride 3.1mg/L (max), 1.373mg/L (av 2019/20)

17/11/20: Murputja  Fluoride 2.2mg/L

23/2/21: Murputja  Fluoride 2.4mg/L

25/5/21: Murputja  Fluoride 2.1mg/L

25/5/22: Murputja NDW Customer Tap Non Potable Fluoride 2.7mg/L (max), (2.47mg/L av. 2021/22)

“Fluoride occurs naturally in seawater (1.4 mg/L), soil (up to 300 parts per million) and air (from volcanic gases and industrial pollution). Naturally occurring fluoride concentrations in drinking water depend on the type of soil and rock through which the water drains. Generally, concentrations in surface water are relatively low (<0.1–0.5 mg/L), while water from deeper wells may have quite high concentrations (1–10 mg/L) if the rock formations are fluoride-rich.” 2011 ADWG. Health Guideline: 1.5mg/L

Murputja (South Australia) – Sodium

22/3/22: Murputja NDW Customer Tap Non Potable Sodium 22/3/22 247mg/L (max)

“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

Murputja (South Australia) – Total Dissolved Solids

22/3/22: Murputja TS NDW Non Potable Total Dissolved Solids 1130mg/L (max)


“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.

Murputja (South Australia) – Hardness

22/3/22: Murputja TS NDW Non Potable Total Hardness 436mg/L (max)


“To minimise undesirable build‑up of scale in hot water systems, total hardness (as calcium
carbonate) in drinking water should not exceed 200 mg/L.

Hard water requires more soap than soft water to obtain a lather. It can also cause scale to form on hot water pipes and fittings. Hardness is caused primarily by the presence of calcium and magnesium ions, although other cations such as strontium, iron, manganese and barium can also contribute.”
