2015/16 – Bendemeer (New South Wales) – Uranium

2015/2016 Uranium – Bendemeer (New South Wales)
Uranium concentrations have been elevated above ADWG in bore 5 in Kootingal/Moonbi and in Airlie Rd bore in Bendemeer
•There is limited scientific data on the health effects of uranium and studies are mostly about
inhalation and/or occupational exposure and cross-sectional studies of communities with elevated uranium levels in drinking water
•Epidemiological evidence suggests renal proximal tubular damage by the presence of biomarkers may occur at levels above 0.1 mg/L and there is little information on chronic long term exposure
•For the Kootingal/Moonbi community Uranium concentration in the reticulated
water tested over 2015 and 2016 range from 0.022 mg/L up to 0.043 mg/L.
For the Bendemeer community, the affected bore was commissioned in 2014 and has provided only up to 20% of the drinking water supply since 2015. Exposure to water from this bore was not considered a concern due to the part contribution and shorter exposure time.
• There is no clear dose response identified in the 7 studies examined
•There is no clinical or histological evidence of kidney disease in the affected
populations at various levels of exposure in the studies examined
•Community testing would provide limited to no benefit due to lack of specificity in biomarkers

Uranium (Information Sourced From 2011 Australian Drinking Water Guidelines)
“Based on health considerations, the concentration of uranium in drinking water should not exceed 0.017 mg/L.”
