Acid-bearing, pyrite-rich acid soil on the surface of lower Currency Creek
Crushed limestone introduced as a measure to contain acid sulphate soils. These mounds of limestone rely on freshwater flows through Currency Creek for distribution.
Heavy vehicular intrusion has exposed dangerous acid sulphate conditions.
Left undisturbed, acid sulphate soils may be harmless but when disturbed, these soils become exposed to oxygen, from which sulphuric acid and heavy metals are produced.
