Johanna Blake, Ph.D.

Biography

Dr. Johanna Blake is a research hydrologist with geochemical expertise at the New Mexico Water Science Center. She received a Master's Degree and PhD in Earth and Environmental Sciences from Lehigh University and a Bachelors of Science Degree in Earth and Planetary Sciences from the University of New Mexico. Johanna has devoted her career to understanding geochemical processes that may effect surface water and groundwater especially related to rock-water, sediment-water, and ash-water interactions. She focuses her research on inorganic chemistry related to mining, sediment, wildfires, and caves and specializes in contaminants such as uranium, arsenic, molybdenum, selenium, lead, and chromium. Johanna has worked on issues related to uranium mining in the Grants Mineral Belt, New Mexico, on the Navajo Nation, and along the Texas Gulf Coast. She has been the lead scientist in New Mexico working on post-Gold King Mine spill research in the Animas and San Juan Rivers and has worked on understanding potential effects of mining on two drinking water reservoirs along the Animas River. Johanna has done work on wildfires and water quality including identifying mechanisms of element mobility from ash. Additionally, she has been working on understanding the hydrology and geochemistry associated with the Snowy River Formation in the Fort Stanton Snowy River Cave in New Mexico.
