Series Description: This report documents the drilling and installation of groundwater quality monitoring wells in Waste Area Grouping (WAG) 1. Data obtained from these wells was used to characterize and assess the WAG in accordance with applicable DOE, state, and EPA requirements. The report is organized numerically by monitoring well numbers 806 to 830. The information includes well location, drill date, name of driller, type of drill used, name of the person who logged the well, decontamination procedures used, well geology, types and amounts of soil samples collected during drilling, why the well was developed (e.g., "to remove dull cuttings, silt, and fines from the monitoring well."), installation of dedicated monitoring well pumps, testing for hydraulic conductivity of the aquifer in the vicinity of the well screen, and Conformance or Nonconformance Reports. Also included are copies of checklists for pre-drilling, notes on decontamination, well logs, well installation/completion forms, monitoring-well materials certification progress reports, and maps of the wells.
