Construction for the Electrical Resistance Heating (ERH) system to treat the source of TCE contamination under the former CTS building is on schedule. Subsurface drilling for the electrodes and temperature monitoring probes is about 80 percent complete. The remaining borings will be completed when the overhead power lines on the CTS site are relocated by the utility company. Additional treatment equipment will be delivered later this week, including condensers, transformers and the regenerative thermal oxidizer. The surface installation of ERH treatment components will begin the week of March 5.
