There is growing concern within the Western Australian government about the potential contamination of Perth’s water supply from bauxite mining. Internal documents show that the government is concerned about the potential for sediment from Alcoa’s bauxite mine to contaminate the Serpentine Dam, given that mining occurs just 300 metres from the water’s edge. Serpentine is Perth’s biggest dam, and changes to Alcoa’s mining methods about five years ago have increased the risk of sediment flowing into the dam.
