RAPID INFILTRATION & EXTRACTION
(RIX)PROJECT
RIVERSIDE,
CALIFORNIA -
80 MILLION
GALLON/DAY PROJECT

CH2M
Hill & CFEST used CFEST Innovative data processing
and modeling technologies for well location, depth, and
extraction rates to capture most of the effluents. This
project has undergone stringent regulatory evaluations
by California State Regulators. These
credentials support our technology capabilities for cost
and time efficient implementation of environmental
restoration projects.

EWM
technologies provide efficient means for mathematical modeling of local site
within regional model. "Real world" complex geometry of external boundaries,
rock outcrop, and variations of grid (horizontally and vertically) are
efficiently represented for relatively accurate simulations. Environmental and
groundwater project implementations cost millions of dollars over the project
life. During past three decades EWM developers have been incorporating
efficient capabilities for wide range of field needs. EWM strongly believes in
designing and assessments of "real world" problems with appropriate
representation of physical shapes as conceptualized.Interactive grid and input
file generation are incorporated for easy alternate site model generation "on
fly".

Each
RIX and RIB site has to demonstrate regulatory
compliance.
EWM 3D particle tracking algorithms provide needed understanding of likely flow
directions and travel time. Since RIB and RIX projects are recharge sites,
groundwater mound created at the RIB and RIX sites causes divergence of
regional from up-gradient flow and do not "pull" the regional contaminants (if
any present) in to the site. However down-gradient flow may cause accelerated
movements. EWM fate and transport
model results assist in quantitative understanding on contaminant migration.

-
Permit
applications and performance assessments require detailed fluid and mass
balances by each basins adjoining to RIX
and RIB sites.
-
EWM
interactively generated grid aligns model element sides along the required
basin boundaries for relatively accurate estimation of fluid and mass balances
in each basin.
-
EWM
groundwater codes generates informative tables of water and mass balances along
with totals of in and out flows between two adjacent basin boundaries.

fate and transport results assists in understanding likely rate of a chemical
migration from each RIB or RIX basin.
