2001/3 + 2016/17: Lameroo (South Australia) – Arsenic, Antimony, Chloride, Sodium

Center map

Lameroo (South Australia) – Arsenic

9/08/2001 Lameroo Arsenic 0.011mg/L
19/09/2001 Lameroo Arsenic 0.01mg/L
12/03/2003 Lameroo Arsenic 0.013mg/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. http://www.health.qld.gov.au/ph/documents/ehu/2676.pdf

Lameroo (South Australia) Antimony

Lameroo Railway Terrace South January 31 2017: Antimony 0.0073mg/L

Antimony: ADWG Guideline 0.003mg/L. Antimony shows similar toxic effects as arsenic. Can be a problem with antimony-tin solder.

Lameroo (South Australia) – Chloride

July 19 2016 Lameroo (South Australia)  Chloride 342mg/L

October 11 2016 Lameroo (South Australia)  Chloride 348mg/L

January 31 2017 Lameroo (South Australia)  Chloride 368mg/L

April 26 2017 Kingstone (South Australia)  Chloride 356mg/L

“Chloride is present in natural waters from the dissolution of salt deposits, and contamination from effluent disposal. Sodium chloride is widely used in the production of industrial chemicals such as caustic soda, chlorine, and sodium chlorite and hypochlorite. Potassium chloride is used in the production of fertilisers.

The taste threshold of chloride in water is dependent on the associated cation but is in the range 200–300 mg/L. The chloride content of water can affect corrosion of pipes and fittings. It can also affect the solubility of metal ions.

In surface water, the concentration of chloride is usually less than 100 mg/L and frequently below 10 mg/L. Groundwater can have higher concentrations, particularly if there is salt water intrusion.

Based on aesthetic considerations, the chloride concentration in drinking water should not exceed 250 mg/L.

No health-based guideline value is proposed for chloride.” 2011 Australian Drinking Water Guidelines

Lameroo (South Australia) – Sodium

19/7/16 Lameroo  Sodium 254mg/L

11/10/16 Lameroo Sodium 256mg/L

31/1/17 Lameroo Sodium 268mg/L

26/4/17 Lameroo Sodium 231mg/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
