soil shredding by talon/lpe
TRANSCRIPT
The ServicesTalon/LPE offers on-site soil sredding services for the treatment of soils impacted by hydrocarbons and other compounds.
Soil ShreddingSoil Shredding is a process by which impacted soil is mechanically broken down into an unconsolidated state to aerate the soil and allow for maximum surface contact with the selected amendments or remediation compounds. The unconsolidated soil is then ejected from the equipment at a high rate of speed.

As the material exits the equipment, various liquid amendments and remediation compounds can be applied through a spray bar system. The spray application is a variable rate system which can be adjusted based on the contaminant concentrations in the soil and the type of amendment being applied.
The ProcessImpacted soils are first excavated and stockpiled at the subject site either by Talon/LPE or the client’s own excavation crew. Talon/LPE personnel assess the impacted soil to determine contaminant concentrations and which, if any, amendments are necessary for the remediation process. A processing area is identified with the client based on the amount of soil to be processed, the type of equipment required and any site limitations or landowner considerations.
The Process
Once the processing area is set up, impacted soils are fed through the shredder with a loader or backhoe. As treated material exits the equipment, it forms 8’ - 12’ tall stockpiles. The shredder is pulled along the processing area by a truck to create loosely formed elongate piles. Whenever space allows, Talon/LPE prefers to leave these piles undisturbed while the remediation compounds continue to react with the contaminants. The loosely piled material allows for better volatilization and off-gassing during the remediation process.
The Process During the shredding process, Talon/LPE personnel will monitor the effectiveness of the treatment by analyzing the processed material with various field testing methods. Additionally, samples will be collected for laboratory analysis to ensure that remediation goals and/or regulatory remediation standards are achieved.
Once laboratory analysis verifies that contaminants have been reduced to below regulatory action levels, the material can be returned to the excavation and used as backfill. Depending on the scope and scale of your project, remediation of your impacted soils can be completed within a matter of days.
The BenefitsThere are significant benefits to soil shredding versus traditional dig and haul or in-situ treatment of impacted soils, such as:
Eliminates the expense of transporting soil to an offsite disposal facility; Eliminates the expense of the disposal facility; Eliminates the liability of transporting and disposing of contaminated material; Eliminates the expense of importing fill material; Eliminates landowner concerns of importing invasive plant species with fill material; Eliminates the need for long-term monitoring associated with in-situ treatment methods.
The LimitationsWhile soil shredding is an excellent tool in our remediation toolbox, it is not the only tool and can be less effective in specific conditions. Soil type and soil chemistry need to be considered when selecting any remediation strategy. Also, high moisture content in certain soil types may reduce the effectiveness of the shredding process.
