BROWNFIELD VS GREENFIELDBROWNFIELD VS GREENFIELD
• BROWNFIELD SITE - Old abandoned or under utilized industrial or commercial site with contamination, usually located within the inner city, but can be found in small towns
• GREENFIELD SITE - Raw undeveloped farm field or woodland

REMEDIATION TECHNOLOGIESREMEDIATION TECHNOLOGIES
• Install recovery wells to pump petroleum product floating on the water table
• Air sparging and soil vapor extraction wells to reduce dissolved petroleum and solvent in sediments and groundwater
• Excavation of tar, lead, PAH, asbestos and petroleum contaminated sediments
• Natural attenuation of groundwater contamination

REMEDIATION STEPSREMEDIATION STEPS
• Excavate to limits then stockpile• Screen soils with field instruments while digging• Segregate stockpiles based on screening levels• Keep digging until meet cleanup goals• Take confirmation samples for laboratory
analysis• Fill and compact after meeting cleanup goals• Haul to landfill
