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

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

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

TerraTherm Enjoys Rapid Growth as ISTR Gains Industry Acceptance

Recently, TerraTherm was featured in Environmental Business Journal’s 2015 Remediation issue. The article, “TerraTherm Enjoys Rapid Growth as ISTR Gains Industry Acceptance,” features an interview with TerraTherm co-founder, CEO and President, John Bierschenk. TerraTherm has grown its revenue nearly three-fold to greater than $30 million over the prior three years. By diversifying its project portfolios and building a strong backlog of upcoming projects, our strong growth rate will continue in 2015, reflecting an expanding demand for quick, predictable and cost effective remediation solutions. Mr. Bierschenk cites overall industry acceptance of ISTR technologies since they first emerged from the enhanced oil recovery … Continue reading

Why I Drive a Tesla

Over the past 2 ½ years, TerraTherm employees and visitors alike have commented on the car I park outside the office, a Tesla Model S all-electric sedan.  “How do you like the car?” “Cool car!” and “How’s it do in the winter?” are commonly heard, and I love talking about it, and giving folks rides, since it truly is a wonderful car: fast, agile, great looking, quiet, safe and reliable.  Its 200-mile range, combined with the ever-growing number of Tesla Superchargers nationwide, has enabled me to drive it as far as New York and New Jersey on occasion, and someday … Continue reading
