Description of the U.S. Geological Survey`s slug-tests at the Hallam Nuclear Facility, July to November 1994
An aquifer test agreement between the US Department of Energy (USDOE) and the US Geological Survey (USGS) was set up to log and measure the aquifer response in two observation wells, IB and 4C at the Hallam Nuclear Facility, Hallam, Nebraska. Observation wells 1B and 4C are owned by the USDOE and were installed by HWS Technologies Inc. of Lincoln, Nebraska, in June 1993. These observation wells were measured monthly from September 1993 to August 1994 by using a graduated steel tape. The accuracy of these water-level measurements is approximately {plus_minus}0.02 foot. Also well 1B contained a submersible pressure transducer to record hourly water-level data during this same period. During access of the wells, personnel wear clean disposable latex gloves, a hard hat, and safety glasses. Directly following each measurement the steel-tape was rinsed with deionized water and the effluent was disposed of in a 55-gallon drum. For the aquifer tests, observation wells 1B and 4C had submersible pressure transducers installed to monitor water-level responses. These pressure transducers were connected to an electronic data logger (edl) to record the water levels, atmospheric pressure from a barometric pressure gauge, and rainfall data from a tipping-bucket rain gauge. The data recorded on each edl was downloaded onto a field computer during each site visit, processed in the field, and then stored on the USGS`s Data General workstations upon return to the District Office.
