Ms. Ritchie has over six years of experience with a variety of groundwater projects such as groundwater management plans, Sustainable Groundwater Management Act (SGMA) implementation planning, field work (including well installation, monitoring, and aquifer testing), groundwater basin characterizations, and GIS database and data management.

With a certification in Geographic Information Systems (GIS), Ms. Ritchie brings experience in database creation and application to groundwater basin investigations. Recently, she has applied her database/GIS skills to an evaluation of contaminant plume migration in a multilayered aquifer in Santa Clarita, CA and to development of hydrogeologic analyses under SGMA in the Modesto, Turlock, and Kern County groundwater subbasins.

Her field experience spans a variety of projects. She has participated in production well installation and testing including logging, evaluation of geophysical logs, aquifer testing, water quality sampling, and vertical profiling for water quality. She has experience in managed aquifer recharge (MAR) feasibility studies in Monterey, Sonoma, Santa Clara, and Riverside counties; some of these studies involve indirect potable reuse (IPR) of recycled water. Her experience also includes infiltration testing, cone penetrometer testing (CPT), and drilling, logging and soil sampling during installation of monitoring wells.

She has increasing responsibility for groundwater monitoring programs, including field monitoring and data management, analysis, and reporting. For example, she currently is responsible for monitoring of groundwater levels, groundwater quality, and subsidence in the City of East Palo Alto and assists with data analysis and annual reporting. She plays a key role in Groundwater Sustainability Plans (GSPs) under SGMA, including compilation and database management of groundwater level and groundwater quality data, analysis of groundwater level trends, documentation of groundwater quality conditions and trends, and preparation of final figures, analyses, and reports.
