This report documents where innovative and established technologies have been used to restore groundwater to beneficial use. This report includes a select number of example National Priorities List (NPL) sites where the remedial action objective (RAO) and associated cleanup levels were to restore groundwater for use as a source of drinking water. Groundwater was restored for use as drinking water at 17 NPL sites and significant progress toward groundwater restoration has been made at an additional 13 NPL sites where contaminants remain above safe drinking water levels in only a few groundwater wells.
