Multiple, stress-level slug tests were performed at selected test/depth intervals within wells 399-2-5, 399-3-22, and 399-4-14 as part of the 300 Area volatile organic compound characterization program at the Hanford Site in Washington State. The temporary test screen lengths were characterized as the boreholes were advanced to their final drill depths and before their completion as monitor-well facilities. Following well completion, slug tests were performed in the final, completed well-screen sections. The objectives of the slug tests were to provide the vertical distribution of hydraulic conductivity with depth at these locations and to support selection of the final well screen-depth interval for each of these monitor-well facilities.
