The Integrated Remediation Technologies (IRT) Group at the Energy & Environmental Research Center (EERC) is a specialized technical group focusing on design and implementation of advanced remediation and treatment systems for cleanup of soil and/or groundwater contamination.

Practicing under the long-standing EERC philosophy of collaboration and an interdisciplinary approach, the IRT Group's success is based on developing effective partnerships with responsible parties, small business, industry, and regulatory agencies.

Innovation
By integrating the most efficient contaminant recovery technologies with engineered in situ degradation processes, the IRT Group finds solutions to considerably reduce the time, labor, and costs required for site cleanup.
Although there are many technologies available for site remediation, often the best ideas are developed while working on-site. For example, a new pressure-monitoring system and integrated telemetric control for the entire recovery and treatment system provide for operational flexibility and considerable labor reduction.

High-Efficiency Contaminant Recovery and In Situ Degradation
Working closely with all parties involved in the remedial process, the IRT provides cost-effective solutions starting from evaluation of the overall remediation strategy to full-scale design and site-specific implementation of the remedial technology selected.

Because the time required for removal of free-phase and highly concentrated dissolved-phase contaminants is critical to the life-cycle design and economics of the subsequent remedial effort, the IRT uses advanced technologies for multiphase contaminant recovery, including mobile systems with integrated treatment for contaminated water and vapor recovered.

Unlike conventional injection, IRT's innovative vacuum-enhanced injectant distribution uses high-vacuum systems to control/support delivery of injected nutrients or reagents to the target zone for in situ contaminant degradation or chemical destruction. The IRT's mobile multipurpose injection systems provide for delivery of oxygen-saturated and nutrient-enriched water and chemical reagents in both liquid and gaseous form.

Apart from technological assets and experience, it is, however, the commitment and dedication of our staff and partners to high professional standards and quality results that have become our trademark.
