Superfund Task Force Listening Session, Recommendation 6: Provide Clarification of Principles for Superfund Groundwater Remediation

Sponsored by: U.S. EPA Office of Land and Emergency Management, Office of Superfund Remediation and Technology Innovation

Open to Environmental Groups and the General Public

Superfund Task Force Recommendation 6: Provide Clarification to the Principles for Superfund Groundwater Restoration recommended actions to analyze a select group of major policies and guidances with special emphasis on: 1) beneficial use designation of aquifers in the near- or long-term, 2) remedial timeframe, 3) phased remedial approaches, and 4) completion strategy. This activity has been broadened to also include additional flexibilities such as the use of 5) monitored natural attenuation (MNA) and 6) technical impracticability (TI) waivers. EPA is seeking input on how groundwater remediation under CERCLA currently incorporates these flexibilities, limitations to their use, and potential ways to increase knowledge and application in future. This information, along with information from additional stakeholders listening sessions, will be used to inform potential future actions as the Agency strives to increase efficiency, reduce time and costs, and to improve groundwater cleanup.

The following questions are offered to assist the participants in focusing comments in response to the Listening Session materials.

  • Of the six flexibilities identified and contained in existing EPA guidance, which do you find the most useful in selecting and implementing groundwater remedial strategies and remedies?
  • What aspects of the six policy flexibilities would benefit from clarification?
  • Can you identify any issues in the use of the six flexibilities?
  • How useful is the current Groundwater Beneficial Use Designation policy and could additional clarification be made?
  • What lines-of-evidence for monitored natural attenuation are the most useful in making an MNA determination and are there possible new lines-of-evidence based on advances in science?
  • How can current EPA MNA policy be clarified to better address ineffective remedies?
  • What are the most important factors to consider in determining an appropriate site-specific remedial timeframe?
  • How are current and future groundwater use and other flexibilities factored into a remediation timeframe analysis?
  • What clarifications to existing Technical Impracticability (TI) guidance would be useful to evaluate the site for TI applicability?
  • Is clarification needed for the successful use of a phased approach in a groundwater remedy?
  • Are the advantages of a phased approach to groundwater remediation clear and understandable, and how is phasing most effectively applied?
  • In your experience, has the use of a completion strategy or plan been useful in facilitating a common understanding amongst all parties for steps and metrics needed for achieving completion goals?
  • How has the use of a completion strategy or plan resulted in optimizing or changing the current groundwater remedy?


A second delivery for Regulated and Consulting Communities will be hosted on June 30th, 2020. For more information on that session, please click here.
