Battelle Conference on the Remediation of Chlorinated and Recalcitrant Compounds 2022

Presenter: Deborah Shaffer Schnell

Description:  Cascade’s vertical inclusion propagation (VIP) process allows controlled vertical inclusions by mechanical separation of the formation through dilation of a vertical casing to initiate the inclusion along an azimuth, followed by injection of food-grade guar carrying the designed ZVI or sand loading.

Join us for a mixing demonstration of guar with iron or sand to see this process in action.

Schedule: Monday, May 23 from 10:30 am to 11:00 am

Description: Join us to see how we developed our colloidal carbon in situ chemistry based on its transport through coarse grained soils in column studies. You’ll be able to view the column setup and testing as we demonstrate colloidal carbon is mobile through coarse grained soils for injection at below fracture pressures. We’ll also introduce the Pathfinder automated injection system and the Direct Push Pulsing Tool, both designed for enhanced distribution of colloidal carbon and other liquid amendments.

Schedule: Tuesday, May 24 from 10:00 am to 10:30 am and Wednesday, May 25 from 2:30 pm to 3:00 pm

Description:  Gently heating a site to 35 degrees C can thermally enhance the biological degradation of many contaminants, and heating to 80-90 degrees C can increase the abiotic hydrolysis reaction rates of specific chemicals by several orders of magnitude. LTTR has the potential to significantly decrease the time and cost of an aerobic or anerobic biodegradation remedy and to sustainably reach the remedial goals for specific chlorinated solvents (e.g., carbon tetrachloride, TCA, DCA, and 1,1,2,2 TeCa) using thermally enhanced hydrolysis without the need or expense for vapor extraction and treatment.

We will have several examples of the heaters and required tooling at the booth for your inspection as well as real-time data from an actual ongoing LTTR site.

Our experts will be on hand to evaluate and provide preliminary LTTR design and costing information for any site you may have. Stop by and learn about how low temperature thermal remediation (LTTR) may be the sustainable thermal approach you are looking for.

Schedule: Monday, May 23 from 11:30 am to 12:00 pm and Thursday, May 26 from 9:30 am to 10:00 am

Description: Have a contaminated site in mind and wonder what it would take (and cost!) to use thermal remediation to clean it up? Stop by our booth with your site information for a personal interactive session with one of our experts to explore if thermal remediation may be a good fit. If you can provide the area and depth, geology, groundwater flow, COCs, and remedial goals for your site, we can model your site and provide a preliminary design, cost-estimate, and schedule. We will also provide a breakdown of the major components of the costs: subcontractors (e.g., drilling and surface cover), materials, labor, rentals, equipment, ODCs, and utilities (electricity and natural gas).

Our design and costing model provide costs for all three ISTR technologies: thermal conduction heating (TCH), electrical resistance heating (ERH), and steam enhanced extraction (SEE), including combinations. We can run several scenarios for your site so you can compare different technologies and approaches. If your site has a PFAS source zone or IDW that needs to be treated, we can also provide costs for treatment of these soils.

These sessions take between 15 and 30 minutes depending on the details and scenarios evaluated.

Schedule: Monday, May 23 from 2:30 pm to 3:00 pm and Wednesday, May 25 from 12:30 pm to 1:00 pm

Description:  Ever wonder what data can be used to aid in tracking and optimizing performance on a thermal project? Stop by our booth for an educational, fun, and hands-on demonstration of TerraTherm’s data acquisition and management system. We will have a table-top version of Brickeye’s (formerly AOMS) state-of-the-art fiber optic temperature sensors connected to our data management website that you can inspect. We use these same sensors and system for every thermal remediation project.  

Accurate real-time measurement of temperatures at a thermal remediation project are critical to understanding how a site, with all its complex features, is responding to heating. You will also have the opportunity to view a complete suite of operational data (temperatures, flows, mass removal, etc.) from several real thermal projects using our data management website.

Let us answer your questions around design, construction, operation, and monitoring of thermal remediation projects.

Description:  In situ stabilization (ISS) provides assurance that contaminants are immobilized providing further protection of leaching to groundwater. While a combination of mixing methods can be applied from augers, rotary heads, and excavator buckets, the success of ISS is based on the combination of amendments blended with the soils.

Join us for a mini treatability study where we’ll determine the best combination of amendments by testing their strength.

Schedule: Wednesday, May 25 from 11:30 am to 12:00 pm
