This fact sheet describes baseline water quality of the Equus Beds aquifer and Little Arkansas River and water-quality effects of artificial recharge by the city of Wichita associated with Phase I (2007–present) of the Aquifer Storage and Recovery project. During 1995 through 2012, more than 8,800 surface water and groundwater water-quality samples were collected and analyzed for more than 400 compounds, including most of the compounds on the U.S. Environmental Protection Agency’s primary drinking-water standards maximum contaminant level list and secondary drinkingwater regulations secondary maximum contaminant level list. Water-quality constituents of concern discussed in detail in this fact sheet are chloride, arsenic, total coliform bacteria, and atrazine. Sulfate, nitrate, iron, manganese, oxidation-reduction potential, and specific conductance also are constituents of concern and are discussed to a lesser extent.
