Royal George (Tasmania) – Lead, Cadmium, Arsenic

Highest Australian reading for Arsenic – Royal George Tasmania: <1.4mg/L Arsenic (2010) “Government tests this week revealed the St Pauls River at Royal George (population 20) contained more than 200 times the Australian drinking-water limit of arsenic, more than 50 times the limit of lead and high levels of cadmium. The heavy metals that leached into the river
during recent heavy rain are believed to originate from a tin mine that ceased production in 1928, raising concerns that the exposure may be long-standing. Exposure to the heavy metals is linked to health risks including cancer, stunted intellectual development, kidney damage and vascular disease…

Arsenic: ADWG 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

Highest lead level recorded in Australia could be that of Royal George Tasmania: <0.5mg/L Lead (2010). Australian Drinking Water Guideline for Lead is 0.01mg/L

Cadmium: Royal George Tasmania: <0.1mg/L Cadmium (2010). The primary route of
exposure of cadmium is via contaminated water or food. Fertiliser can be a source of excessive cadmium as can rainwater tanks. It has been linked to cancer, lung disorders, kidney disease and autoimmune disease. ADWG Guideline. 0.002mg/L,
