Sara LeAnn (Caldwell) Eldridge
I am a Microbiologist in the Studies Section.
I started with the USGS New Mexico Water Science Center in 2003 as a student studying Earth Science with an emphasis on subsurface (groundwater) microbiology. After receiving an MS in Biology in 2009, I worked as a Hydrologic Technician and later, Microbiologist, with the Oregon Water Science Center, Klamath Falls Field Station. In Oregon, I worked primarily on monitoring the frequent cyanobacteria blooms and associated toxins (“HABs”) and environmental parameters in Upper Klamath Lake. In 2018, I transferred to the Wyoming-Montana Water Science Center, and I am now building a microbiology/microbial ecology program and supporting water-quality studies throughout Montana and Wyoming.
