Draft Technical Impracticability Evaluation for Iodine-129 in Groundwater at Hanford: 200-UP-1 Operable Unit
- Pacific Northwest National Lab. (PNNL), Richland, WA (United States)
Target restoration cleanup levels for contaminated groundwater are established by applicable or relevant and appropriate requirements (ARARs) determined by federal and state drinking water quality standards. When these standards cannot be met within a reasonable timeframe due to limitations of available remediation technologies or other factors, the U.S. Environmental Protection Agency (EPA) may evaluate the technical impracticability (TI) of attaining the required groundwater cleanup levels, and establish alternative, protective remedial strategies. This report provides information relevant to consideration of a TI waiver on the current federal 1 pCi/L drinking water standard (DWS) for iodine-129 in the 200-UP-1 Groundwater Operable Unit (OU) of the Hanford Site if ongoing evaluations of treatment options do not identify a feasible treatment technology.
