Lithology, Hydrologic Characteristics, and Water Quality of the Arkansas River Valley Alluvial Aquifer in the Vicinity of Van Buren, Arkansas

placed in areas with a greater percent sand.Use of a horizontal well configuration near the river to increase production may depend on infiltration of river water to supplement water removed from storage, especially where areas of lower permeability sediments might be encountered within the surrounding alluvium.If a poor hydraulic connection exists between the river and the alluvium, as indicated by this study, then production will depend on ample precipitation and recharge throughout the year and groundwater storage sufficient to prevent declining water levels where pumping rates exceed recharge.
