In an effort to provide an overview of the susceptibility of aquifers in Union County, Arkansas, to contamination from potential surface sources, hydrogeologic conditions were assessed at 51 public-supply well sites and potential contaminant sources were located. Almost all of these wells are completed in the Sparta Sand, either in the locally known Greensand aquifer or the underlying El Dorado aquifer. The city of El Dorado and surrounding area have been affected by urban growth and industrial activities. The major industry in Union County is the petrochemical industry. Major sources of potential contamination in Union County include numerous surface waste impoundments, 6 active landfills, and more than 300 injection wells. The overview of the susceptibility of aquifers to contamination from potential surface sources was based partly on the computation of travel times of ground water through confining units and from areas of recharge to points of withdrawal.
