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

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
