Remediation Systems

Remediation System Construction

CRA has constructed hundreds of remediation systems using both traditional and innovative technologies.  Our design and operation and maintenance capabilities complement our construction capabilities.  Because of CRA's diverse range of capabilities, we can provide engineered solutions that result in significant cost-savings to our clients, from remedial work at chemical plants, refineries, and other manufacturing operations to more traditional landfill remediation work.

CRA's team of professionals work together to develop and implement strategies that are designed to control costs and maximize efficiency.

CRA's remedial technology experience includes:

• Soil vapor extraction
• Sparging
• Vapor enhanced recovery
• In situ/ex situ enhanced biological treatment
• Material management (e.g. drums, sediments, sludges)
• Material stabilization/solidification/fixation
• Cutoff walls (e.g. soil-bentonite, cement-bentonite, sheet pile)
• Deep collection trenches (e.g. biopolymer)
• Reactive barrier walls
• Groundwater extraction
• Soil flushing
• Bioreactors
• Air stripping
• Carbon adsorption
• Chemical reduction treatment for heavy metals
• Product recovery (e.g. LNAPL and DNAPL)
• Funnel and gate systems
• Risk assessments
• Industrial wastewater permitting
• Emergency spill response
• Waste characterization
