When it comes to controlling acid soil drainage, only
Australia has enacted specific planning regulations
to prevent the formation of acid sulphate soils. Any
response to acid sulphate drainage from mines
and soil has usually been restricted to liming of the
acidified soil or spoil heaps but Trinity Inlet in North
Queensland, Australia, provides a recent example
of remediation through controlled restoration of tidal
flooding, whereby existing acidity is neutralized by
tidewater, and re-establishment of a tidal regime stops
further acid generation (Smith and others 2003).
