> Groundwater Remedies Selected at Superfund Sites
purple divider

Over a 17-year period from 1982 through 1999, more than 2,200 Records of Decision (RODs) have been signed for 1,451 Superfund sites, including 989 RODs addressing the remediation of contaminated groundwater at 787 Superfund sites. Groundwater remediation continues to be a priority for the U.S. Environmental Protection Agency (EPA), and remedies that have been specified in RODs for groundwater remediation include treatment (including groundwater pump and treat [P&T] and in situ treatment) and monitored natural attenuation (MNA).

This report documents the selection of groundwater treatment and MNA remedies at Superfund remedial action sites. It presents data on groundwater treatment and MNA remedy decisions and analyzes trends in these decisions over time. The focus of this report is on groundwater treatment and MNA remedies that result in a reduction of contaminant concentrations or mobility. Groundwater containment and groundwater-other remedies are not addressed.
