Kimberly Beisner is a Research Hydrologist for the New Mexico Water Science Center. She received a Master's of Science Degree in Geology from the University of Utah and a Bachelors of Science Degree in Geology from the University of Kansas.

Kimberly's USGS experience started in the Utah Water Science Center as a graduate student working on mercury and selenium associated with the Great Salt Lake and abandoned uranium mines in southern Utah. Following graduation, she joined the Arizona Water Science center where she has worked on geochemical studies related to the lands withdrawn from uranium mining near the Grand Canyon, water resources at Saguaro National Park, and stable isotope and noble gas evaluation groundwater of the Verde watershed to understand recharge elevation. She served as the New Mexico Water Quality specialist and is now a research hydrologist focused on multiple geochemical and anthropogenic tracers including per- and polyfluoroalkyl substances and continues to work with the Arizona Water Science Center in the Grand Canyon.

Assessing influence from wastewater treatment facilities on Glorieta Creek and the Pecos River within Pecos National Historical Park, New Mexico, February–October 2022

The Pecos National Historical Park protects 2.9 miles of the Pecos River and part of Glorieta Creek within the park boundaries. Updated water-quality data can assist resource managers in determining if effluent from two nearby wastewater treatment plants (WWTPs) is affecting the quality of the water in the Pecos River and Glorieta Creek within the park. Water samples were collected four times in 2
