2007/9 + 2018/20: Parilla (South Australia) – Arsenic, Total Dissolved Solids, pH

Parilla (South Australia) – Arsenic

23/01/2007 Parilla Arsenic 0.019mg/L
16/10/2007 Parilla Arsenic 0.014mg/L
15/04/2008 Parilla Arsenic 0.011mg/L
25/05/2008 Parilla Arsenic 0.014mg/L
4/08/2009 Parilla Arsenic 0.0171mg/L
1/09/2009 Parilla Arsenic 0.0178mg/L

Arsenic: Australian Drinking Water Guideline = 0.01mg/L

Arsenic is bioaccumulative and symptoms may take 10-15 years to develop after expsoure at high levels. Drinking water can be contaminated with inorganic arsenic through wind blown dust, leaching or runoff from soil, rocks and sediment. Groundwater sources such as bores will usually have higher arsenic levels than surface water. In major Australian reticulated water supplies concentrations of arsenic range up to 0.015mg/L, with typical values less than
0.005mg/L. https://www.health.qld.gov.au/ph/documents/ehu/2676.pdf

Parilla (South Australia) – Total Dissolved Solids

2018/19: Parilla (South Australia) Total Dissolved Solids 690mg/L (max), 672.5mg/L (av)

2019/20: Parilla Total Dissolved Solids (by EC) 650mg/L (max), 645.75mg/L av.


“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.

Total dissolved solids (TDS) consist of inorganic salts and small amounts of organic matter that are dissolved in water. Clay particles, colloidal iron and manganese oxides and silica, fine enough to pass through a 0.45 micron filter membrane can also contribute to total dissolved solids.

Total dissolved solids comprise: sodium, potassium, calcium, magnesium, chloride, sulfate, bicarbonate, carbonate, silica, organic matter, fluoride, iron, manganese, nitrate, nitrite and phosphates…” Australian Drinking Water Guidelines 2011
