Abstract

Process for assessing and remediation of a contaminated site comprising the steps of assessing the contaminated soil and/or groundwater at a contaminated site involving geophysical scans of the contaminated site and pH, microbial, salinity and metal testing of the soil and/or water contained in the site or other site specific parameters. Remediation of the soil and/or water at the site insitu is followed involving electro-kinetics of the contaminated site. Water testing is carried out during remediation to determine the effect of remediation. Following remediation, an assessment of the remediated soil and water involves electromagnetic scans of the contaminated site as well as pH, microbial, salinity and metal testing of the soil and water contained in the site Once the results of all tests are analysed, the electro-kinetic remediation can be deemed successful or optimized and continued for an extended duration. Effluent water collected from electrodes during remediation can be treated using electrodialysis or suitable technology and then used to flush the vadose zone or reinjected into the groundwater zone the water was extracted from.

Claims

1. A process for assessing and remediating a contaminated site comprising the steps of:

assessing contaminated soil and/or groundwater at a contaminated site by conducting geophysical scans of the site;

assessing the contaminated soil and/or groundwater by analyzing the soil and water samples for chemical parameters;

remediating the soil and/or groundwater by electro-kinetics;

during remediation, assessing the contaminated site by conducting hydrological and chemical tests of the water; and

assessing the remediated soil and/or groundwater by conducting electromagnetic scans of the site.

2. The process for assessing and remediating a contaminated site in claim 1 which further includes the step of assessing contaminated soil and water by conducting salinity, pH, and metal tests of the soil and water before remediation.

3. A The process for assessing and remediating a contaminated site in claim 1 which further includes the step of assessing contaminated soil by conducting microbial tests before remediation

4. The process for assessing and remediating a contaminated site in claim 1 which further includes the step of remediating effluent water by electrodialysis

5. The process for assessing and remediating a contaminated site in claim 4 which further includes the step of reusing the remediated water during electro-kinetic remediation or reinjecting the remediated water into a groundwater zone the remediated water was previously extracted from.

6. The process for assessing and remediating a contaminated site in claim 1 which further includes the step of conducting chemical, pH, salinity and metal tests of the soil and water following remediation.

7. The process for assessing and remediating a contaminated site in claim 1 which further includes the step of conducting microbial tests of the soil following remediation.

8. The process for assessing and remediating a contaminated site according to any one of claims 1 to 7 wherein the contaminated site is contaminated with elevated salinity.
