Temperature Monitoring Matters

As a thermal remediation company, one of our most important factors to keep track of during operation is the subsurface temperature. The subsurface temperature is one of the main parameters used to determine how close to or far from reaching our treatment goals we are. Typical contracts require us to meet certain subsurface temperature requirements before confirmatory soil sampling can begin. This means we need a reliable temperature monitoring system so we can determine when a site has reached its goals. Thermocouples vs. Fiber Optics In the past, thermal vendors have been using thermocouples (typically Type T or Type K) … Continue reading

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

Achieving Work-Life Balance

I think most of us work to earn money to pay the bills.  How much of our time is devoted to this effort?  It is reasonable that a comfortable “balance” exists between work and personal life but just what does that mean?  To me it means a stress free life.  There are certain “jobs” that require our attention around the clock and throughout the calendar (24/7 in hip-speak). A Project Manager’s job at TerraTherm would fall under this category. We must work day and night and always be available in order to ensure the projects run smoothly. There are other … 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

What’s the Temperature? Thermal Modeling and its Importance in Thermal Remediation

What is a model? A beautiful person who struts down a run way, a scaled down sculpture of the Empire State Building, or a series of equations that describe some phenomenon? Did you guess all of the above? Gold star! Models come in many different shapes and sizes. In the environmental consulting and remediation industry, the word “model” often refers to a numerical model. Numerical models are tools that we use to better understand a system. They can be used to make predictions and to test hypotheses. The thermal models that we customize and construct in house at TerraTherm are … Continue reading
