Environmental Sciences Laboratory (ESL)

The U.S. Department of Energy (DOE) created the Environmental Sciences Laboratory (ESL) in 1991. 

Geochemists, ecologists, and other scientists use ESL to perform applied research, laboratory-scale demonstrations of soil and groundwater remediation and treatment technologies, and pilot-scale tests to supplement numerical modeling efforts.

Specialized analytical services performed in the laboratory continue to support research projects, site characterization, and routine environmental monitoring activities. Over the years, ESL has been equipped with more analytical instruments that have expanded its capabilities beyond chemical analysis.
