2016 In Review

I’m pleased to provide a brief review of TerraTherm’s progress toward our mission to be the worldwide leader in the development and implementation of thermal remediation of organic contaminant source zones. I am thankful to those customers we had the honor of serving this past year.  Team TerraTherm is  dedicated to earning and keeping our customers’ trust and goodwill, by always endeavoring to fully comprehend and meet their remediation and related business objectives. TerraTherm started the year by adding another international partner, Beijing Enviro-Chem Environmental Technology CO., Ltd (Beijing Enviro-Chem). Beijing Enviro-Chem and TerraTherm are pleased to join forces in … 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

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

Thermal Treatment of Fractured Rock – How is it Different?

Fractured rock sites are different – often it is difficult even to determine how deep the Non-Aqueous Phase Liquid (NAPL) has gone, and to define what we refer to as the “source area”. Some sites have NAPL in the fractures, and some have most of the mass trapped in the matrix, into which it has diffused over decades. This blog post discusses the two main challenges: How to decide on the thermal treatment volume without making the problem worse. How to design and implement an effective and safe thermal system. For any aggressive source treatment to be cost-effective, it is … Continue reading

Why Data Management is the Most Underrated Aspect of Thermal Remediation Operations

There are those who think data management sounds boring.  What could be less stimulating than numbers in columns and rows?  But to anyone who needs to know exactly what is going on in the soil, these data are about the most interesting and exciting news around.  No, I’m not saying that us soil nerds are easily amused, I’m saying that those process numbers and field data reveal trends that tell a detailed story and provide actionable information that may streamline the path to completion.  When it comes to optimizing a thermal remediation project, data management, along with a lot of … Continue reading

FAQ: Why TerraTherm Chose Electric Heaters Over Gas-Fired

When you consider precision heating, simplicity, reusability, low maintenance, carbon footprint, and safety, TerraTherm’s electric heaters beat gas heaters on all counts. Here’s why; TerraTherm evaluated electric and gas-fired heaters early on, and concluded that in-well electric heaters are the better choice. We compared the two because many of TerraTherm’s Thermal Conduction Heating (TCH) ISTD patents are broadly written with respect to the means of heating, and would permit the use of any of a number of potential heating means. We concluded that electric heaters are the best choice for the following reasons: TerraTherm’s electric heaters deliver a pre-determined wattage over … Continue reading

The High Value of Thermal Treatability Studies

Laboratory treatability studies are often one of the first logical steps when considering In Situ Thermal Remediation (ISTR) at a given site. In relation to the full-scale source remediation, treatability studies can be a wise and relatively low cost investment in a proof of concept. You might begin with a lab study if you have a unique mix of target compounds in the treatment area, or a challenging geological matrix. Or perhaps certain stakeholders need some extra “convincing” that ISTR will work at your site.  A study performed on actual site materials can quantitatively demonstrate the effectiveness of various thermal … Continue reading
