Innovative Technology
CRA is dedicated to developing and providing innovative approaches to site remediation. CRA offers expertise and database resources to identify and assess potential innovative technologies based on site conditions, as well as develop conceptual remedial strategies. We maintain fully equipped in-house laboratories for conducting treatability studies and can offer the support of full-scale field implementation and monitoring of the remedy. Our main goal is to reduce overall site remediation costs through the implementation of passive, cost-effective innovative technologies with a bias toward in situ techniques.
The following is a brief description of some of the innovative technologies that have been and continue to be evaluated.
- Enhanced Natural Attenuation - Use of enhanced situ anaerobic and aerobic sequential zones for treatment of groundwater and landfill leachates
- In Situ and Ex Situ Bioremediation - For treatment of soils, sediments, sludges, groundwater, and leachates
- Chemical Oxidation - For treatment of groundwater with particular application to dense non-phased liquids (DNAPL)
- In Situ and Ex Situ Stabilization/Solidification - treatment of soils, sludges, and sediments
- Engineered Wetlands - For treatment of landfill leachates and ecological restoration
- Reactive Barriers - For treatment of groundwater
- Phytoremediation - For erosion control, containment, and uptake/degradation of contaminants
- Respirometry - The measurement of oxygen uptake (aerobic respirometry) or biogas generation (anaerobic respirometry) by microorganisms, which can be used to measure the biological treatability of wastes and to assess the efficiency of wastewater treatment plants or biodegradation of specific substances
