The Road to a Successful Remediation is Paved with Data

Accurate data routinely collected can be the difference between a successfully completed thermal remediation project, and one with extended operations, costing the client money. TerraTherm designs and executes a reliable data collection process during In Situ Thermal Remediation (ISTR) projects that specifically targets key operational data, therefore enhancing system performance, reducing energy consumption, and documenting when project goals are met. Depending on the complexity of a site and the specific remedial objectives, any number of data analyses can be performed, but the quantity and quality of data are paramount. The data are used to create detailed mass and energy balances … Continue reading

In Situ Thermal Remediation (ISTR) Market Trends

Through recent competitive proposals it has become obvious that the ISTR market is trending towards a more competitive, commodity-style product. While TerraTherm often ranks high on quality and approach, there is an obvious need to reduce base pricing in order to stay competitive for the smaller, more straightforward sites. Tier One Pricing Solution: TerraTherm’s history of uninterrupted success provides an impetus for clients (e.g., Federal, State, and Private) to consider TerraTherm’s Tier One solution for ISTR sites. Tier One offers a simpler and more streamlined In Situ Thermal Desorption (ISTD) project delivery approach, focusing on essential project elements and price … 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

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
