Remote communities affected by uranium in drinking water

THOUSANDS OF REMOTE RESIDENTS EXPOSED TO LEVELS OF URANIUM ABOVE GUIDELINE LEVELS.   The recently published WA Auditor Report “Delivering Essential Services to Remote Aboriginal Communities” has raised more concerns regarding water quality in remote Aboriginal communities in three regions of Western Australia: The Goldfields, the Pilbara and Kimberleys……….

Uranium is a radioactive heavy metal where exposure has been associated with kidney damage. Uranium has also been linked to reproductive problems and DNA damage.

Impacted Western Australian communities

The total number of WA remote residents impacted by uranium above guideline levels in drinking water probably now totals around 500 people (with perhaps an additional 500 – 1000 people in the Northern Territory). There have also been hundreds more people in Queensland and New South Wales exposed to relatively high levels of uranium in their drinking water over the past few years. The majority of people impacted will be Aboriginal.

Uranium in drinking water can be difficult to treat if no alternative supplies can be found. The source of the uranium in impacted communities is sourced from local geological formations and groundwater………

Uranium breaches were confined to four communities in the Pilbara in 2018/20: Pia Wadjari (8), Burringurrah (5), Parngurr (3) and Kiwikurra (1). Crocodile Hole in the Kimberley also reported one breach. …..

Despite problems in Western Australia, the Northern Territory also continues to suffer from uranium in drinking water in a number of communities. Chronic breaches have occurred in 3 communities, Laramba, Willowra and Wilora over the past decade and probably much longer.

The three communities where uranium levels consistently exceed Australian drinking water guidelines in the Northern Territory. Laramba residents have most likely been exposed to uranium at levels 2-3 times higher than the Australian Drinking Water Guidelines for many years. The highest recorded levels at Laramba each year also appear to be increasing……

Uranium in drinking water has also recently occurred in three Queensland communities. The highest levels were detected in January 2021 at Dajarra (population 200 located 1000km west of Mackay) in western Queensland at 0.046mg/L, almost three times higher than the safe guideline…….

In October 2016 uranium above guideline levels was also detected in the New South Wales communities of Kootingal, Moonbi and Bendemeer. Tamworth Regional Council apologised for the “oversight”, which had left residents’ drinking water with high levels of uranium for at least two years…..

Radionuclides or radiating emitting elements in drinking water (breaching 1mSv/yr) over the past decade or so have included the communities Kings Canyon, Alice Springs, Borroloola and Binjari in the NT. The Victorian community of Goorambat also recorded levels of Alpha activity for radionuclides over guideline levels in 2012/13.

Wilmington SA, had radon (a radioactive gas produced from decay of radium 226 in soil and minerals) detected in the community above guideline levels of 500Bq/L in October 2018. In South Australia uranium guidelines were breached at Saltia Creek (October 2019) and Woolshed Creek over 2016/17, however at both of these locations water is deemed to be non-potable.

Existing and “Decommissioned” uranium mines also continue to leach radioactive water into the environment and will continue to do so for thousands of years. BHP’s Olympic Dam mine has a history including seepage from tailing impoundments into underlying groundwater. Ranger Uranium Mine (where toxic tailings are currently being dumped into pits) has leached contamination into Kakadu National Park, Rum Jungle uranium mine (1954-71) caused Acid Mine Drainage pollution to the East Finniss River where 640,000 tonnes of tailings were discharged damaging 100sqkm of floodplains. Mary Kathleen Mine and Ben Lomond Mine in Queensland have also caused downstream pollution. Anyone downstream of these leaking mine sites could also be jeopardised through exposure to waterways downstream of the mines. Nuclear blasts at Maralinga and Emu Field in the 1950’s also lead widespread contamination of Australia through nuclear fallout, including drinking water reservoirs and water tanks.  https://www.foe.org.au/uranium_in_australian_drinking_water_snapshot
