SAGE was engaged to conduct an independent Human Health Risk Assessment for the Cadia Valley Operations in Orange, NSW. The HHRA was conducted in response to community concerns about impacts to drinking water supply from air and dust emissions from the mine.
The HHRA used a number of data sources to estimate intakes to residents of 12 neighbouring suburbs to the mine. The chemicals of concern identified were metals associated with the vent emissions and tailings dam composition.
The HHRA concluded that the contribution to overall risk from Cadia Valley Operations was 1-17% of the overall risk, with potential risks identified with the consumption of drinking water impacted with copper which was a result of localised impacts from the home or property.
The HHRA was submitted to the NSW EPA and was independently peer reviewed.
