DOE established the ESL in Grand Junction, Colorado, in 1991 to support its programs. ESL scientists perform applied research and laboratory-scale demonstrations of soil and groundwater remediation and treatment technologies.

• Installation, monitoring, and operation of permeable reactive barriers.
• Research of permeable reactive barriers and treatment cells.
• Performance assessment and optimization of groundwater remediation systems.
• Groundwater characterization.
• Coupled hydrogeochemical modeling for groundwater remediation.
• Soil and groundwater phytoremediation.
• Design and monitor landfill covers.
• Analogs of long-term performance of waste disposal cells.
• Water balance studies, lysimetry, and vadose zone monitoring.

• Contaminant transport laboratory.
• Segmented test columns.
• Plant ecophysiology equipment.
• Mobile laboratory.
• Analytical equipment.
• Petrographic analysis.
• Soil classification and hydraulic properties.
