Gilberton, Queensland (Gold Coast) : ウィキペディア英語版 | Gilberton, Queensland (Gold Coast)
Gilberton is a rural locality in the northern part of City of Gold Coast, Queensland, Australia. ==Environmental issues==
Gilberton has acid sulphate soil in naturally water-logged conditions. The lowering of the water table due to drainage work on the Pimpama River allows oxidisation of the iron sulfide to create sulphuric acid which can, in turn, enable the release of iron, aluminium and other heavy metals, doing damage to both the natural and built environment. Application of lime to neutralise low pH levels and the maintenance of broad shallow drains to reduce oxidisation are used to mitigate the problem.
