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

How We Use Hazard Recognition Tools to Help Eliminate Incidents On-Site

No matter where you are, you’ll always hear that saying, “There is no ‘I’ in Safety”.  This statement could not be any more true, especially here at TerraTherm. For us, safety is a total “Team” effort, from the top of the management team, to the employees in the field.  Safety is paramount for our success in all of our projects, and it shows in our safety record. With zero OSHA recordable incidents or lost days for 2016, TerraTherm was recently awarded the Cascade Environmental, LLC’s (Cascade) Obsidian Award. This award is given to the Cascade business units that achieve no recordable … Continue reading

To Wipe or Not to Wipe: Ensuring Equipment Cleanliness after Decontamination

At TerraTherm, our wellfield and process equipment can take a beating! Between high concentrations of hazardous chemicals, corrosive conditions, and elevated temperatures, piping and equipment generally need a bit of TLC before being put back into circulation for use at another site. When TerraTherm is operating at sites with persistent organic pollutants such as polychlorinated biphenyls (PCBs) or dioxin/furans, decontamination becomes even more difficult and even more important.  Along with typical decontamination procedures such as steam cleaning and pressure washing, washing with a non-ionizing  detergent (e.g. Simple Green) is typically necessary. Additional rinsing of equipment with specialized products such as … 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

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

Speeding down the Data Highway

Interpreting analytical data collected from our process streams during operations is sort of like driving a car forward, but only being able to look at the rearview mirror. During operations at our thermal remediation sites, TerraTherm routinely collects a variety of process vapor (whole air canisters/bottle-vacs, and/or solid adsorbent tubes) and liquid samples.  The exact sampling and analytical methods used vary from site to site; each site is truly unique with different combinations of subsurface contaminants, site geology/groundwater chemistries, heating approach, as well as site specific cleanup goals and permitted discharge limits. These process analytical data are used to: Evaluate … 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
