Remediation of contaminated sites with cement, also called solidification/stabilization with cement (S/S with cement) is a common method for the safe environmental remediation of contaminated land with cement. The cement solidifies the contaminated soil and prevents pollutants from moving, such as rain causing leaching of pollutants into the groundwater or being carried into streams by rain or snowmelt. Developed in the 1950s, the technology is widely used today to treat industrial hazardous waste and contaminated material at brownfield sites i.e. abandoned or underutilized properties that are not being redeveloped because of fears that they may be contaminated with hazardous waste. S/S provides an economically viable means of treating contaminated sites. This technology treats and contains contaminated soil on site thereby reducing the need for landfills.

Famous quotes containing the words contaminated and/or cement:
“A happy people I call them still, whose peace and genuine morals have not been contaminated with European vices; and whose errors are only the errors of ignorance, and not the rooted depravity of a pretended civilization, and a spurious and mock Christianity.”
—J.G. (John Gabriel)
“It is fair to assume that when women in the past have achieved even a second or third place in the ranks of genius they have shown far more native ability than men have needed to reach the same eminence. Not excused from the more general duties that constitute the cement of society, most women of talent have had but one hand free with which to work out their ideal conceptions.”
—Anna Garlin Spencer (1851–1931)
