permeability

The measure of a material's ability to transmit liquids.The passage of soil contaminants into groundwater increases as soil permeability increases.On the other hand,in situ remediation—removal or decomposition—of groundwater contamination is easier as permeability increases.For a color map of the United States showing the relative permeability of soils across the country, see the Web site page of the Environmental Protection Agency at www.epa.gov/iwi/1999sept/iv20_usmap.html.
