Avoid Costly Off-Site Hazardous Waste Disposal with TerraTherm’s Economical On-Site Heated-Box Approach

Transportation and disposal of soil or sediment impacted with hazardous levels of organic contamination can be costly and contributes to traffic congestion. In addition, the liability associated with the material tends to follow when shipped off site. If the material ends up in a landfill, that liability may never go away. Treating on-site eliminates these issues and with TerraTherm’s new thermal approach, it can yield significant savings for our clients. Introducing In Pile Thermal Desorption® (IPTD®) This ex-situ (above ground) technology can: Treat polychlorinated biphenyls (PCBs) and dioxin-contaminated materials on-site, quickly and efficiently, Remove volatile organic compounds (VOCs) from mixed and … Continue reading

New Frontiers for In Situ Thermal Remediation: Using High Resolution Site Characterization to Improve Conceptual Site Model Accuracy and Lower Project Costs

As a Cascade Company, one of the major benefits TerraTherm is able to extend to our clients is a whole new suite of capabilities that we now have more readily available to us. These capabilities allow us to better define the target treatment zone (TTZ) and Conceptual Site Models (CSM), enabling us to minimize cost for treatment while ensuring that all of the source material is treated. This not only saves our clients money, but it also limits future liability associated with any missed source materials outside of the TTZ. One of the capabilities we have available to us is an … Continue reading

Bench Scale Thermal Treatment of 1,4-Dioxane

1,4-Dioxane (not to be confused with dioxin…although we also can certainly thermally treat that! See our updates from the Danang Vietnam project) is an industrial chemical widely used as a chemical stabilizer for chlorinated solvents. It is of environmental concern due to its classification as a probable human carcinogen coupled with its unique chemical properties such as high water solubility (and therefore high subsurface mobility in groundwater), low octanol-water partition coefficient (log Kow), and relative resistance to biodegradation [1]. Due to these properties, 1,4-dioxane is often present on the leading edge of a contaminant plume in groundwater and presents unique … Continue reading

Moving Environmental Equipment – Logistics Done the Right Way at TerraTherm

A prodigious level of activity, intense excitement, as well as a bit of angst can precede the start of any big project. We’ve recently been experiencing all of that at TerraTherm! We reached the point in the schedule where two of our projects required the treatment equipment to be delivered almost simultaneously. Ten tractor-trailer loads of remediation equipment needed to be moved to our two, separate New England sites in the same month. All told, nearly six million dollars’ worth of equipment had to be staged, loaded, and transported to both locations in a matter of two weeks. One of … Continue reading

The Road to a Successful Remediation is Paved with Data

Accurate data routinely collected can be the difference between a successfully completed thermal remediation project, and one with extended operations, costing the client money. TerraTherm designs and executes a reliable data collection process during In Situ Thermal Remediation (ISTR) projects that specifically targets key operational data, therefore enhancing system performance, reducing energy consumption, and documenting when project goals are met. Depending on the complexity of a site and the specific remedial objectives, any number of data analyses can be performed, but the quantity and quality of data are paramount. The data are used to create detailed mass and energy balances … Continue reading

Webinar: In-Pile Thermal Desorption® (IPTD®) for Treatment of POPs-Contaminated Soil and Sediment

In case you missed our last installment of “Inside In Situ Thermal Remediation”, TerraTherm’s informational webinar series, you can find a recorded version here: “In-Pile Thermal Desorption® (IPTD®) for Treatment of POPs-Contaminated Soil and Sediment” Presented by TerraTherm’s Co-Founder, Chairman and Chief Scientist, Ralph S. Baker, Ph.D., this webinar was recorded on September 11th, 2014. Description: Soil or sediment contaminated with Persistent Organic Pollutants (POPs) including PCBs, PAHs, organohaloginated pesticides, Dioxins and Furans and other recalcitrant organics, as well as mercury can be treated effectively at elevated temperatures. By contrast, conventional treatment typically requires excavation and transportation of the soil … Continue reading

Operating at an In Situ Thermal Remediation Site

Seeing a TerraTherm site operate is an extraordinary thing. The view of the stack, faithfully discharging clean water vapor into the air, the metallic chirping of In Situ Thermal Desorption (ISTD) heaters oscillating in their well casings, and the low frequency humming of the treatment equipment truly is a unique experience. The principals of subsurface heating with Thermal Conductive Heating (TCH) are simple, but to actually implement this aggressive source zone treatment technology is another thing altogether. It is impressive to think about how quickly a source area can be treated, when something like 15 years ago, the only other … Continue reading
