Description:
Soil venting has been used to remediate soils in the United States since the early 1980's. It is a recognized standard technology in Germany and is widely utilized in the Netherlands. While its application can sometimes be complex, the basic principle behind sail venting is simple. Air extraction or injection wells are used to create a pressure differential which causes air circulation through contaminated soils or consolidated geologic media. oil venting is often preferable to above ground onsite and offsite treatment of soils because of lower cost. Venting involves the use of standard and readily obtainable commercial and industrial equipment. Capital expenditures and energy consumption are often far less than other remedial technologies such as thermal desorption. Another distinct advantage of venting is that air is introduced into soils which are often deficient in oxygen causing concomitant removal of VOCs and semivolatile organic compounds through biodegradation.
