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
