Science in Action: Robert S. Kerr Environmental Research Center, Ada, Oklahoma

The Robert S. Kerr Environmental Research Center (RSKERC) in Ada, Oklahoma, is EPA’s center of expertise for groundwater remediation and ecosystem restoration research. RSKERC provides critical research in response to EPA office, partner, and stakeholder needs. This research is led by the Groundwater Characterization & Remediation Division (GCRD), part of EPA's Center for Environmental Solutions and Emergency Response. GCRD directly supports three of EPA’s six National Research Programs that provide the scientific foundation needed to protect public health and the environment:

  • Sustainable and Healthy Communities
