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

Liquid Granular Activated Carbon System Design Considerations

When developing a liquid treatment system design at TerraTherm, we keep in mind that the system will be temporary and have an overall short duration; typically 12 months or less. This means that we need to design and select a process configuration that minimizes the cost of meeting applicable discharge requirements. Cost elements taken into consideration include: To design the most cost-effective treatment system for each project, we rely on site owners and their consultants to provide detailed soil and groundwater characterization and identify the specific discharge requirements that will apply to the thermal remediation program. Liquid phase activated carbon … Continue reading

How TerraTherm’s ThinkThermal Website and Data Plotter Connect Clients with Real Time Data

Thermal projects are quick – we often heat and treat a site in less than 6 months.  It is crucial to be on top of all the data and know when it is time to stop, or when to collect confirmatory samples to document performance.  Every day and week counts, so the project team must have immediate access to the data from the field. As an engineer and data manager for TerraTherm, I have found that two of the most useful tools that I have to help keep our project teams and clients up to date are the ThinkThermal.com website … Continue reading

The Process of Hot Soil Sampling and Why it’s Worth the Effort

Do you like to get your hands dirty? For TerraTherm, hot soil sampling is often the defining parameter for the timeline and completion of an In Situ Thermal Remediation project, and for myself, was a great learning experience and an opportunity for me to try something new and exciting. Cleanup of contaminant source zones is what TerraTherm is known for. And those source zones that keep us in business are analyzed through soil sampling. For most project sites, the soil is sampled at various locations before the project begins, sometimes a few times during operations, and one final confirmation round … Continue reading

World’s Largest In Situ Thermal Desorption Project: Challenges and Solutions

TerraTherm and its In Situ Thermal Desorption (ISTD) sublicense holders have cleaned close to 50 sites, but what happens when we are presented with one that is remarkably large with more than 100,000 cubic yards (76,500 m3) of PCE and TCE rich soils to a depth of over 40 feet (12 m)? The site in particular that was presented to TerraTherm was a former aerospace manufacturing facility and had to be remediated in less than a year. Successfully completed by TerraTherm, this site in Teterboro, New Jersey is now the largest ISTD project to date. The redevelopment of this former … Continue reading
