Abstract: As a preliminary phase in a predictive mass‐transport modeling study, ground‐water samples were collected from an unconfined, landfill‐contaminated aquifer over a five‐month time period. The dilution effect of recharge ...

Abstract: The U.S. Geological Survey's two‐dimensional solute‐transport and dispersion model (the method of characteristics, or MOC, model) accurately reproduces the chloride‐concentration distribution observed in a buried‐valley ...

Abstract: Spatial data are collected at various locations. Two cases are considered: (1) The observations are independent; and (2) the observations are correlated. If the data are assumed to be normally distributed with constant ...

Abstract: The application of correction factors to measured ground‐water elevations is an important step in the process of characterizing sites contaminated by petroleum products such as gasoline. The water‐table configuration exerts ...
