Experience:
Water Rights Compliance and Basin Management Monitoring and Reporting
Program, San Juan Basin Authority (SJBA)
Ms. Sanchez is the project engineer responsible for data collection and management
for the San Juan Basin Authority’s groundwater monitoring program. The monitoring
program includes: measurement of groundwater levels, water quality sampling;
collection of monthly production totals at wells throughout the basin, and collection of
precipitation data. Ms. Sanchez supervises the collection of data and subsequently
manages, processes, and analyzes water level and water quality data on a monthly
basis, and provides updates to the San Juan Basin Authority Technical Advisory Group.
Ms. Sanchez is also responsible for the San Juan Basin Authority’s CASGEM compliance
and for preparing annual reports summarizing the findings of the monitoring program
to ensure compliance with water rights permit conditions. In 2016, Ms. Sanchez
assisted in the development of the 2016 Adaptive Pumping Management Plan by
analyzing historical production data, coordinating with the groundwater modelers and
analyzing modeling results.
San Juan Basin Groundwater and Desalination Optimization Program, San Juan Basin
Authority
Ms. Sanchez served as the project engineer for the San Juan Basin Groundwater and
Desalination Optimization Program. In this project, WEI evaluated the physical and
economic feasibility of projects to increase recharge to the Basin with storm and
recycled waters, implemented a seawater extraction barrier, and optimized production

schemes to adaptively manage groundwater storage in wet and dry climate cycles.
Other key components of the feasibility study are to evaluate the regulatory challenges
in implementing the recycled water recharge projects as they will explore new frontiers
and issues associated with recharging water in an impaired basin. Ms. Sanchez was
involved in performing the surface water modeling to calculate new yield, coordinating
with the groundwater flow modelers, analyzing MT3D groundwater quality modeling
results, and calculating recycled water underground retention time. She was also
involved in preparing preliminary designs and operating plans for a new in-stream
rubber dam system to turn a stream into 2.5-mile long recharge basin.
Coldwater Basin Safe Yield Studies, Coldwater Basin Operating Committee
Ms. Sanchez is the project engineer responsible for preparing the annual report for the
Coldwater Basin. In 2006, WEI conducted an analysis of the native safe yield of the
Coldwater Basin in Riverside County to establish the relative pumping rights of the two
major pumpers of the basin—the City of Corona and the Elsinore Valley Municipal
Water District. A water-rights agreement was executed between the City and the
District based on this analysis, which requires annual reporting and the re-
determination of the native safe yield once every five years, based on the monitoring
data collected to date. Ms. Sanchez’s responsibilities include collecting and analyzing
groundwater level, groundwater production, groundwater quality, and imported water
delivery data; and the accounting of pumping, storage, and water-rights
Total Dissolved Solids Studies, Santa Ana Watershed Project Authority
Ms. Sanchez worked as a project engineer on the SAWPA Basin Monitoring Program
Task Force TDS study to Characterize the Volume-Weighted Summertime TDS
Concentration of POTW Discharge above Prado Dam. The objective of this study was to
evaluate the causes of recent exceedances of the Santa Ana River Reach 3 TDS
concentration objective and to characterize the relative magnitude of each factor
contributing to the exceedance of the surface water objectives.
Implementation of the 2013 Amendment to the 2010 Recharge Master Plan Update
(RMPU), Chino Basin Watermaster
Ms. Sanchez is a project engineer for the implementation of the 2013 Amendment to
the 2010 RMPU. The 2010 RMPU utilized state-of-the-art surface water models,
developed by WEI, to estimate stormwater recharge in spreading basins and in
localized recharge facilities that will be constructed to comply with the 2010 MS4
permits. The investigation also determined the existing recharge capacity for imported
and recycled waters and the future recharge capacity requirements. Subsequent to the
approval of the 2010 RMPU, the 2010 UWMPs were released, and the groundwater
production projections were substantially less than assumed in the 2010 RMPU. A
Stakeholder Committee was formed to conduct further analysis of the projects
recommended in the 2010 RMPU, introduce and analyze new yield enhancement and
production sustainability projects, and develop a finance and implementation plan for
the recommended projects. The 2013 Amendment was approved by the stakeholders
and the Court. Ms. Sanchez is responsible for preliminary hydrologic and hydraulic
design work to refine recharge projects, coordinating Watermaster’s efforts to collect
MS4 project information, and reviewing interim submittals from design contactors.
