Soil washing technologies are water-based ex situ processes for mechanically scrubbing soils to remove contaminants. One process removes contaminants from soils and sediments by dissolving or suspending them in the wash solution. Another process concentrates them by particle size using physical separation techniques. This is based on the fact that most of organic contamination is partitioned in organic fraction (leaves, roots, etc) and five particles of soil or sediment, and that minimal contamination is present in larger particles (sand size and larger). Combination of these two technologies is often used. Further treatment or final disposal of concentrated end product is required because process does not destroy contaminants, but concentrates them into small volume.
