Groundwater remediation is a component of more than 90% of active Superfund sites and achieving groundwater remedial action objectives (RAOs) can take years or even decades. The purpose of this guidance is to help focus resources on the information and decisions needed to effectively complete groundwater remedies and to ensure that these remedies protect human health and the environment. This document presents a recommended "groundwater remedy completion strategy" for evaluating Superfund groundwater remedy performance and making decisions to help facilitate achievement of RAOs and associated cleanup levels.
