Abstract
A method and system for removing contaminants from contaminated soil at a site utilizes particle size segregation and particle density segregation to yield a plurality of fractions, whereby each of the fractions are tested and identified for the presence of unacceptable levels of contaminants, and the soil fractions from the contaminated soil at the site corresponding to the identified contaminated fractions are collected for subsequent disposal or treatment, while the remaining untainted soil fractions are homogenized and returned to the site.
Claims30
A method for removing contaminants from contaminated soil at a site, comprising the steps of:
- soil diagnostic testing including the steps of:
- extracting a representative sample of the contaminated soil from the site;
- segregating the sample into a plurality of size fractions according to particle size;
- segregating each of the size fractions into a plurality of density fractions according to particle density;
- identifying the fractions containing the presence of unacceptable levels of contaminants representing at least a portion of the total contaminant amount of the sample;
- and
- field system design and implementation based upon said soil diagnostic testing including the step of:
- removing soil fractions from the contaminated soil at the site corresponding to the identified contaminated fractions from the sample.
A system for removing contaminants from contaminated soil at a site, comprising:
- a soil diagnostic testing and sampling facility adapted for segregating a sample of soil from the site into a plurality of fractions based on at least one of particle size and density, and for testing the plurality of fractions to identify tainted fractions containing the presence of unacceptable levels of contaminants;
- and
- a contaminated soil removing facility adapted for removing soil fractions from the contaminated soil at the site corresponding to the contaminated fractions from the sample as identified by the soil diagnostic testing and sampling facility.
