Combined Technology/Contaminant Resources

Superfund Cleanup Technologies
The Superfund Remedy Report (SRR), Fifteenth Edition, was published by EPA in July 2017. The SRR 15th Edition summarizes remedy decisions back to 1982 with a focus on the analysis of Superfund remedial actions selected from fiscal years (FY) 2012 to 2014. The report includes remedies selected in 308 decision documents (Records of Decision [RODs], ROD amendments, and Explanations of Significant Differences with changes to remedy components) signed in this three-year period. The SRR compiles data on overall remedy selection and remedies for source materials (such as soil and sediments), groundwater, surface water and air related to vapor intrusion. The report appendices summarize all the remedy components selected for sources and groundwater in each individual decision document. View the Superfund Remedy Report (SRR), Fifteenth Edition.
