Groundwater Resources of Union County, New Mexico: A Progress Report
— K.E. Zeigler, B. Podzemny, A. Yuhas, and V. Blumenberg

Beginning in 2007, the Northeastern Soil and Water Conservation District Board began a groundwater monitoring program for Union County in northeastern New Mexico. Repeated regular static water level measurements, sampling of wells and springs for major element chemistry, ¹⁴C and tritium, as well as geologic mapping and examination of petroleum and water well data have led to a better understanding of the groundwater resources beneath Union County. Agricultural producers and communities rely on a partitioned system of smaller aquifers created by geologic complexities in the subsurface. Here we provide a progress report on development of data sets related to these groundwater resources and discuss changes in local agricultural management practices that have resulted from these efforts.
