Heavy Metals in Soil: Treat with Blastox
What are Heavy Metals in Soil? The EPA requires a Toxicity Characteristic Leaching Procedure (TCLP) test to determine if the heavy metals in soil needs to be managed as hazardous or non-hazardous waste. Soils exhibiting hazardous characteristics need to be disposed of at a facility permitted for that material at a high cost. Soils treated in the field prior to off-site disposal can be rendered ...

ETC Soil Remediation, A More Efficient Way to Treat Explosives-Contaminated Soil.
When industries are ready to restore sites contaminated with explosives-impacted soil, they can cut their timeline in half — while staying on budget — by choosing to deploy advanced technology that’s proven to outpace traditional soil remediation methods.In the U.S., it’s estimated there are over 1.2 million tons of explosives-impacted soil contaminated sites. It goes without saying that this ...

Thermal Remediation of Karst Limestone – Redstone Arsenal, Alabama
Abstract: Electrical resistance heating (ERH) was used for the thermal remediation of two sites at Redstone Arsenal (RSA) near Huntsville, Alabama. Both sites feature karst limestone with heavy clay overburden. The two sites are located about five miles (10 km) apart, but differ considerably in the characteristics of the limestone. At site RSA-053, the heavy clay is underlain by very hard, ...

Electrokinetic Separation
Introduction The principle of electrokinetic remediation relies upon application of a low-intensity direct current through the soil between ceramic electrodes that are divided into a cathode array and an anode array. This mobilizes charged species, causing ions and water to move toward the electrodes. Metal ions, ammonium ions, and positively charged organic compounds move toward the cathode. ...

Oil-Contaminated Soil Remediation: The Process of Cleaning Up Soil Polluted With Oil
Oil contamination of soil is a widespread problem that can have serious environmental and health impacts. The presence of oil in the soil can result from a variety of sources, including spills from storage tanks or pipelines, leakage from vehicles, and improper disposal of waste oil. In order to protect the environment and public health, it is essential to clean up contaminated soil and restore ...

Review of Biofiltration - Effect of Support Media on Biofilter Performance
Technologies for removal of hazardous pollutants from air have gained increased importance following the 1990 Clean Air Act Amendments (CAAA). Biofiltration is an emerging and attractive technology for the removal of volatile organic chemicals (VOCs) present at low concentrations in air. Traditional VOC removal technologies involve physical or chemical processes such as adsorption, condensation, ...

Slurry Phase Biological Treatment
Slurry phase biological treatment involves the controlled treatment of excavated soil in a bioreactor. The excavated soil is first processed to physically separate stones and rubble. The soil is then mixed with water to a predetermined concentration dependent upon the concentration of the contaminants, the rate of biodegradation, and the physical nature of the soils. Some processes pre-wash the ...
