What We Do

The Groundwater Characterization and Remediation Division (GCRD) plans, coordinates, and conducts an applied, national-scale, customer-driven research program to provide data, tools, models, strategies, and technologies to protect and restore groundwater.  GCRD research and outreach programs include basic and applied studies of the physical, chemical, and biological processes that control the transport of water, chemicals, and/or microorganisms of known or emerging concern in subsurface environments.

GCRD also provides research and outreach for applied site-specific studies to determine the effects of management practices on pollutant removal or pollution avoidance. We consult with EPA Regions, Program Offices, and other stakeholders on specific problems and needs that can be addressed by GCRD research.
