  • Soil remediation with heated soil
    Patent number: 7004678
    Abstract: Methods are provided for remediating contaminated soil. The methods may include collecting contaminated soil at a plurality of treatment sites. The contaminated soil at one or more of the plurality of treatment sites may be at least partially contained. The method may include heating soil at a first site with a plurality of heat sources to substantially reduce contamination of the soil at the first site. Soil at a second site may be heated using a plurality of heat sources. A portion of vapors produced from the second site may be allowed to enter the substantially uncontaminated first site. Contaminants within the portion of vapors produced from the second site may be at least partially destroyed at the first site.

  • Remediation of soil piles using central equipment
    Patent number: 6881009
    Abstract: Methods are provided for remediating contaminated soil. The methods may include collecting contaminated soil at a plurality of treatment sites. The contaminated soil at one or more of the plurality of treatment sites may be at least partially contained. Contaminated soil at the plurality of treatment sites may be treated with equipment in a central treatment facility. Treatment of the plurality of sites may be coordinated such that equipment in the central treatment facility operates substantially continuously as soil is delivered to, treated at, and removed from various treatment sites. The plurality of sites may be treated in a sequential manner, in which soil is delivered to one site, treated at a second site, and removed from a third site substantially simultaneously.
