2012/16 – Pipalyatjara (South Australia) – Total Dissolved Solids
August 2012 – November 2016: 694mg/L (average from 5 detections. Five above ADWG)
“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.
2012/16 – Pipalyatjara (South Australia) – Hardness
2012/16: Hardness average 415.8mg/L (5 detections out of 5 above guideline)
“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.”
