Hydraulic conductivity for the pumice layer was set at 100 ft/d, based on literature values for sorted sand (Freeze and Cherry, 1979, p. 29; Wolff, 1982, p. 84; Fetter, 1994, p. 98). Hydraulic conductivity of the peat layer was set at 0.084 ft/d, the mean of slug tests performed on piezometers PZ-WRDK and PZ-AGDK because peat is the predominant lithology of the saturated zone in each piezometer.
