Soil Washing
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.

Understanding Phosphorus Behavior in Soils
Many of the soils in the Noble Research Institute service area are low in phosphorus (P).Some of this is due to low P level in the soils' parent material and otheris due to cropping history and nutrient removal. Either way, since P is anessential element for plant growth, we must supply additional fertilizer Pif high crop yields are desired and soil test P levels are low.

This additional water infiltrates into the soil and percolates through the rootzone. During percolation, it takes up part of the salts in the soil and takes these along to deeper soil layers. In fact, the water washes the salts out of the rootzone. This washing process is called leaching (see Fig. 106). Fig. 106. Leaching of salts

Polluted soil and solid waste treatment
The treatment of polluted soils will be carried out through the use of soil washing and solvent extraction technologies. The treatment of polluted soils, sludge and other wastes with similar physical characteristics is made possible by using an innovative, patented technology, called ENSOLVEX ®, based on a process of pollutant extraction with a suitable solvent (ethyl acetate).
