Questions
Cadiz Water Project Renewable Resource
Unsaturated Alluvium
Fenner Valley Aquifer
Proposed groundwater drawdown from pumping is 15 feet at the edge of Fenner Valley
Saturated Alluvium
~1400 ft Elevation drop
Clipper Mountain derived groundwater contributes to the Fenner Valley groundwater system but is una�ected by changes in Fenner Valley water table
Igneous Extrusives(Volcanic)
300 ft
Proposed Cadiz Well�eldElevation ~1000 ft
Relatively Solid Rock (essentially no groundwater)
Groundwater Barrier(fault zone)
Fractured Rock Units with groundwater
Fractured Rock Unit

Drawdown Water Table
Fractured Rock Unit Very Permeable Bedrock
New York Mtns. ~40 Miles North
Providence Mtns.(13 to 30 Miles NNW)
Bonanza Spring
Fractured Rock Unit with
in�ltrating groundwater
11 Miles from Bonanza Springs to Well-field Perched groundwaterfrom spring ontop ofbedrock
Bonanza Spring groundwater source Rain water In�ltrates fractured rock in thewestern Clipper Mountains, and �ows downward to water table, then moves laterally toward spring within Fractured Rock Unit
WATER TABLE ELEVATION 2100 ft
Key Points Bonanza Spring is fed by rainwater percolatinginto rocks in the western Clipper MountainsThe Fenner Valley Alluvial aquifer is independent of the western Clipper Mountain groundwater unit

Microvi Benefits:• Self-contained Support Media• Minimal Bacterial Sloughing• Full Scale Installations• Works in Any Reactor
Many commercial biological denitrification systems are just entering the marketplace. Most require some media: granular, plastic or membrane to support the bacteria
