 The Kingston toxic waste story began in 1931 when cyanide and other toxins such as acid waste used in the Mount Taylor gold refining process were disposed of around the mine site.When the mine closed in 1954, the Albert Shire Council started to allow used recycled oil processing wastes to be dumped into a sludge pit on the site; this practice continued until 1967.From 1968 to 1973 the main open-cut pit was used as a domestic and industrial waste tip.
