Monitoring Extracted and Treated Vapor Streams from a Thermal Remediation Site in Real-Time

Monitoring is an important component to any successful remediation project.  This point is explained further in Steffen Griepke’s previous blog post, “Why Data Management is the Most Underrated Aspect of Thermal Remediation Operations”. The more information you can collect, the better! Conventional portable monitoring instruments, such as a photoionization detector (PID) or flame ionization detector (FID) are relatively inexpensive and convenient, but are unable to detect certain constituents or quantify their presence, especially in hot, moist vapor streams.  This blog post provides an example of a technique TerraTherm is using for selected sites to overcome these limitations. TerraTherm’s FTIR system … Continue reading

Teterboro, NJ – The Biggest In Situ Thermal Desorption (ISTD) Site in the World – Remediation Completed!

The Teterboro Landing Site in New Jersey was historically used for manufacturing precision aerospace components. The site is located adjacent to Teterboro Airport and less than 10 miles from Manhattan and New York City. TerraTherm was contracted in November 2011 to remediate an area that was impacted with Chlorinated Volatile Organic Compounds (CVOCs). The total volume of the In Situ Thermal Desorption (ISTD) treatment area was 122,300 cubic yards. The thermal remediation system designed, built and operated by TerraTherm included a wellfield with a total of 907 Thermal Conduction Heater (TCH) wells, 35 Multi-Phase Extraction (MPE) wells, 116 horizontal Vapor … Continue reading

Preparing your Site for Thermal Remediation

A TerraTherm job is similar to other construction-style jobs in terms of logistics. Once all of the design and contracting issues have been resolved and a date to proceed has been set, it’s finally time to mobilize!  Mobilization is often one of the most overlooked aspects of every construction-type job. Generally, we tend to think that work begins once we arrive on site, forgetting all the hard work that precedes it.  Mobilization is one aspect of every job that can prove greatly beneficial to all involved if planned properly, or alternately, can create future headaches when overlooked.  The transition can … Continue reading

Drilling and Well Installation at In Situ Thermal Desorption (ISTD) Sites

Once all of the modeling, treatability studies, and design work have been completed, it’s on to the next step for TerraTherm and time to mobilize our staff, resources, and equipment to the field to install the thermal wellfield. This is an essential task that must be done precisely in order to ensure thermal success. It does not matter how well the site was modeled or designed; if the installation is not done correctly it can lead to issues with thermal treatment operations and potentially jeopardize the success of the project. Plan of Attack: When the wellfield layout has been finalized, … Continue reading

Where Did In Situ Thermal Remediation (ISTR) Methods Come From?

Looking at a built-up thermal site with heaters, wells, manifold piping, process gear, and the advanced monitoring systems which can be accessed from anywhere in the world, it can be tempting to wonder how this all came about…  Hundreds of engineering details, program logic controlling automatic operation of valves, heating systems, and treatment equipment.  Yet, the systems run overnight and on weekends, with nobody there to baby-sit them.   Most of the features of a modern In Situ Thermal Remediation (ISTR) site have evolved over a period of less than 25 years.  I will try to explain the evolution here. Chemicals … Continue reading
