Ms. Grimm has worked on projects focused on drinking water, stormwater, and groundwater. From these projects she has gained experience in data collection and analysis, water quality monitoring, mapping in Geographic Information Systems (GIS), and isotope hydrology. Her field experience is specialized in surface water where she conducted biological assessments, pathogen indicator assessments, and water quality assessments to manage pollution and toxicity in receiving waters.

Ms. Grimm developed expertise on groundwater isotope hydrology through her M.S. thesis work. At Lawrence Livermore National Laboratory (LLNL) she conducted analysis of tritium and terrigenic helium-4 for apparent groundwater ages. She also analyzed the stable isotopes of water and noble gas recharge temperature to gain information on aquifer recharge sources for flow patterns. She compared the results to independently computed residence times from the Integrated Water Flow Model (IWFM) to aid a Groundwater Sustainability Agency (GSA) in Butte County with their Groundwater Sustainability Plan (GSP) for the Sustainable Groundwater Management Act (SGMA).
