1.5 Types and Sources of Data

Compilation, review and analysis of multiple types of data were necessary to refine the
groundwater flow model. The various types of data are summarized in Figure 5 and include
geology, soils/lithology, hydrogeology, surface water hydrology, climate, land use, topography,
and groundwater recharge and recovery. Groundwater levels, well construction information,
groundwater quality, and pumping test data were stored in a relational database expanded from
database files provided by the USGS and Wildermuth Environmental, Inc. (WEI). Other types
of data necessary for analysis were compiled into spreadsheets. Historical groundwater quality
data was collected and can be incorporated into future model analyses if a water quality transport
component is added to the existing groundwater flow model.

Data for updating and refining the groundwater flow model were obtained from multiple sources:

Geological Data including geologic maps and cross sections were obtained from the USGS and
the California Geological Survey (CGS).

Soils/Lithological Data including detailed lithologic logs from wells and test boreholes,
geophysical logs, and drillers’ logs from wells and test boreholes were obtained from the
California Department of Water Resources (DWR), City of Banning, Yucaipa Valley Water
District (YVWD), South Mesa Water Company (SMWC), and Beaumont-Cherry Valley Water
District (BCVWD).

Hydrogeological Data including groundwater levels, pumping test data, and groundwater
chemistry were obtained from the San Gorgonio Pass Water Agency (SGPWA), WEI, BCVWD,
SMWC, YVWD, and City of Banning.

Groundwater Recharge and Recovery Data including spreading basin locations and
dimensions, artificial recharge, water well construction, well locations, groundwater production,
and information for septic return flow estimates were obtained from SGPWA, WEI, BCVWD,
SMWC, YVWD, and City of Banning.

Hydrological (i.e. Surface Water) Data consisted of stream gage data along Little San
Gorgonio Creek and San Timoteo Creek and was obtained from BCVWD and USGS.
Wastewater treatment plant discharge data was obtained from the City of Beaumont.

Climate Data was acquired from the Riverside County Flood Control and Water Conservation
District for the Beaumont weather station and DWR’s California Irrigation Management
Information System (CIMIS) at the University of California, Riverside station.
