Soil Washing | FRTR Remediation Technologies Screening …

Soil washing is an ex situ process that reduces the volume of contaminated material that must be further treated or disposed. Soil washing systems operate on the principal that most contaminants of concern (COCs) bind to the finer soil fraction, consisting of clays, silts, and fine organic matter as opposed to the larger sand and gravel fraction.

Full-scale soil washing system remediates Superfund site

One of the first full-scale soil washing systems in the United States is currently being used to remediate the King of Prussia (KOP) Technical Corporation Superfund site (Winslow Township, New Jersey). The soil washing facility began operating at the site in June 1993. About 20,300 tons of soil require remediation, and operations were expected ...
