Geographical Distribution
Acid sulfate soils are widespread around coastal regions, and are also locally associated with freshwater wetlands and saline sulfate-rich groundwater in some agricultural areas. In Australia, coastal acid sulfate soils occupy an estimated 80,000 km2, underlying coastal estuaries and floodplains near where the majority of the Australian population lives. Acid sulfate soil disturbance is often associated with dredging, excavation dewatering activities during canal, housing and marina developments.
Acid sulfate soils that have not been disturbed are called potential acid sulfate soils (PASS). Acid sulfate soils that have been disturbed are called actual acid sulfate soils (AASS).

Famous quotes containing the words geographical and/or distribution:
“Men’s private self-worlds are rather like our geographical world’s seasons, storm, and sun, deserts, oases, mountains and abysses, the endless-seeming plateaus, darkness and light, and always the sowing and the reaping.”
—Faith Baldwin (1893–1978)
“The question for the country now is how to secure a more equal distribution of property among the people. There can be no republican institutions with vast masses of property permanently in a few hands, and large masses of voters without property.... Let no man get by inheritance, or by will, more than will produce at four per cent interest an income ... of fifteen thousand dollars] per year, or an estate of five hundred thousand dollars.”
—Rutherford Birchard Hayes (1822–1893)
