TerraTherm - a Cascade Company applications

It is estimated that there are over 3,000 former Manufactured Gas Plant (MGP) sites across the United States. Another 4,000 dot the landscape of Canada, the UK, continental Europe and Japan. These sites were built long ago on rivers or harbors, often on the outskirts of towns and cities; locations that are now frequently in close proximity to infrastructure, buildings and residential areas. Many underlie or abut valuable commercial, residential, and municipal properties, posing environmental hazards to ground and surface waters. The urgency of remediation has increased due to a potent blend of community activism, regulatory pressure, high real estate values, and the need to reduce liability in light of the Sarbanes-Oxley Act and other measures.

TerraTherm provides rapid, thorough, and predictable remediation of Brownfields property. Our in situ thermal processes can ensure rapid closure, avoid delays, eliminate uncertainty, avoid excavation, and optimize property value. In situ thermal remediation is a reliable, lower risk, and less disruptive way to achieve your remediation goals.

In Situ Thermal Remediation (ISTR) Beneath and Around Existing Buildings and Infrastructure; In Situ Thermal Remediation (ISTR) technologies, including In Situ Thermal Desorption (ISTD), the Electro-Thermal Dynamic Stripping Process (ET-DSP™), which is an advanced form of electrical resistance heating, and Steam Enhanced Extraction (SEE) have been demonstrated effective in treating source zones with limited access and those adjacent to or beneath buildings and other infrastructure.

Thermal Conduction Heating (TCH) is applicable in fractured rock and other complex formations such as: Tight and fractured clays,
Saprolite, Shale, Sandstone, Limestone, Dolomite, Fractured igneous and metamorphic rock, Permeable basalt, Karst limestone.

We can help you achieve site closure and enable the sale or redevelopment of your site in a predictable timeframe with highly reliable results. This is made possible by: Our broad array of thermal remediation technologies, each tailored to the site-specific conditions and contaminants; Tested and proven field operations, processes, and teams; Expertise in designing projects to ensure outcomes without the need for further remediation; and, Our ability to assure a shorter project cycle and verification that goals are achieved by sampling before we shut down or demobilize.
