Tara Rolfe is a Senior Hydrogeologist based in Pasadena, California with more than 17 years of experience focused on potable water supply and groundwater development and sustainability.


Tara’s work with both public and private clients has included groundwater and spring water development, water supply resilience, basin-wide water management, regulatory compliance, litigation support, and development and implementation of adaptive management plans (AMPs). Tara developed AMPs for water management to protect endangered fish species and riparian forest and for mitigation and minimization of future land subsidence in southern California. For each of these projects, Tara has developed and implemented adaptive management plans that included a focused monitoring program, annual data analysis and reporting to stakeholders, and mechanisms to update the monitoring programs and implement potential future mitigation activities. AMP implementation included coordination with stakeholders to collect existing data and utilize existing facilities for future monitoring, CEQA support, the design and installation of additional monitoring facilities, and ongoing collection of data, information synthesis and reporting. Monitoring programs were comprised of groundwater elevation, production, and quality; surface water flow and quality; riparian habitat quality and extent metrics including vegetation and wildlife surveys and remote sensing techniques (NVDI and aerial mapping); weather and climate data; and extensometer data. Tara coordinated with stakeholder groups comprised of both technical and non-technical members to review and approve the adaptive management plans and prepared annual reports for the stakeholder groups to facilitate critical water management decisions.

To advance the state of the practice, Tara continues her participation in professional organizations such as the American Water Works Association (AWWA), where she is involved in the Water Well Technology Committee. Tara has presented on the topics of water well condition assessments and well rehabilitation at the AWWA CA/NV annual fall conferences.
