Status of Groundwater Levels and Storage Volume in theEquus Beds Aquifer near Wichita, Kansas, 2012 to 2014By Cristi V. Hansen, Joshua A. Whisnant, and Jennifer L. Lanning-RushAbstractDevelopment of the Wichita well field in the Equus Bedsaquifer in southwest Harvey County and northwest SedgwickCounty began in the 1940s to supply water to the city ofWichita. The decline of water levels in the Equus Beds aquiferwas noted soon after the development of the Wichita well fieldbegan. Development of irrigation wells began in the 1960s.City and agricultural withdrawals led to substantial water-leveldeclines. Water-level declines likely enhanced movement ofbrines from past oil and gas activities near Burrton, Kansas,as well as natural saline water from the Arkansas River intothe Wichita well field area. Large chloride concentrations maylimit use, or require the treatment of water from the well fieldfor irrigation or public supply. In 1993, the city of Wichitaadopted the Integrated Local Water Supply Program to ensurean adequate water
