The BILBY recompletion project was conducted in support of the Nevada Environmental Restoration Project at the Nevada Test Site (NTS), Nye County, Nevada. This project is part of the DOE`s Underground Test Area (UGTA) subproject at the NTS. The primary UGTA tasks include collecting geological, geophysical, and hydrological data from new and existing wells to define groundwater quality and to determine pathways and rates of groundwater migration at the NTS. A program of drilling or recompleting wells near the sites of selected underground nuclear tests (near-field studies) was implemented as part of the UGTA subproject to obtain site-specific data on the nature and extent of migration of radionuclides produced by an underground nuclear detonation. The BILBY project is named for the underground nuclear test conducted in Emplacement Hole U-3cn in 1963. The site consists of a collapse sink (centered on the collar of the original emplacement hole) and several wells collared within the sink. Two of the wells were recompleted for this project
