    Soil Exploration – Purpose, Planning, Investigation and Tests

    The nature and extent of soil exploration depends upon the ultimate use to which the results of the investigation will be applied. For example, for structures which transmit heavy load on the soil, the aim of soil exploration is to provide data which will help in the selection of proper types of foundation, its location and design of foundations.

    Soil Washing - CLU-IN

    For soil washing, contaminants sorbed onto fine soil particles are separated from bulk soil in a water-based system on the basis of particle size. The wash water may be augmented with a basic leaching agent, surfactant, or chelating agent or by adjustment of pH to help remove organics and heavy metals.

    Soil Washing | Geoengineer

    Jan 29, 2013 · Soil washing is an ex-situ remediation technique that removes hazardous contaminants from soil by washing the soil with a liquid (often with a chemical additive), scrubbing the soil, and then separating the clean soils from contaminated soil and washwater (US EPA 1993, 1996). The concept of soil washing is based on the theory that contaminants are prone to bind to fine grained soils (silts .
