Hazardous Substances It was once a common occurrence for closed mines to be abandoned with no regard for making the site safe with minimal environmental impacts (figure 5.22).

It is much easier and cheaper to remove the hazardous substances while personnel and equipment are available. Cleaning up abandoned sites such as the former Yerranderie mine in New South Wales is a much more expensive undertaking (LP Hazardous p.27). Yerranderie is an historic abandoned silver-lead mining town southwest of Sydney near the World Heritage Listed Blue Mountains National Park. The site is approximately 12km upstream from Sydney’s major water supply dam, Warragamba. Mining at Yerranderie occurred between 1898 and the 1930s with significant silver, lead and gold being recovered. Minimal rehabilitation occurred post mining. In 2003, intensive environmental studies found that small areas of the site had arsenic contamination levels which were potentially hazardous to human health and the surrounding environment, in particular Sydney’s water supply dam. At some locations the material contained up to 25% arsenic. Existing fencing and signage surrounding these areas could only be considered a temporary solution to protect the health and safety visitors to the historic site. For these reasons, a robust longer term management solution was required. The successful project resulted in substantial rehabilitation of the Yerranderie site. Risks to the surrounding environment and Sydney’s water supply were reduced and safety was improved for visitors and tourists.
