Pipalyatjara 1997-1999

The salinity of these groundwaters is 640-770 mg/L TDS with nitrate concentrations of 30-35 mg/L and fluoride concentrations < 1 mg/L. These values are all within the Australian Drinking Water Guidelines (1996). The 1997 water quality investigation detected total coliform counts in the supply lines (Fitzgerald et al., 2000).

Total Dissolved Solids

“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.
