NEWCREST MINING LIMITED CADIA Human Health Risk Assessment A Human Health Risk Assessment (HHRA) commissioned by Cadia in response to community concerns regarding air and water quality has concluded that there is no impact on human health, and that the associated risk is 'low and within acceptable limits' when measured against Australian health standards. Conducted by a NSW EPA accredited auditor from SAGE Environmental Services, the study assessed the potential risks to human health within the community surrounding Cadia from operating emissions (modelled by January 2022 February 2023) and environmental sample data collected from a residential drinking water sampling program. The risk assessment was then independently reviewed and verified by a Victorian EPA-accredited auditor from Senversa. The HHRA identified several pathways where there could be potentially elevated risks due to copper exposure from using tap water. In all instances where increased risks were found, the main factor was the tap water itself - a direct correlation with building materials. The difference in the amount of copper between the tap and tank could be up to 1000 times greater than in the tank and aligns with results from the NSW EPA's water sampling program. While cadmium was also identified as a potential concern at one property, it too was attributed to building materials. The level of all other contaminants measured was low and within relevant human health standards. A copy of the Human Health Risk Assessment conducted by SAGE Environmental Services, along with all other environmental monitoring reports, is available on the Cadia website www.cadiavalley.com.au.
