Project Purpose
Field Investigation that seeks to improve the scientific understanding of the properties of the Lower Tuscan Aquifer system (LTA).– Physical parameters affecting percolation of surface water to the LTA
Interaction between surface water and groundwater– Interaction between surface water and groundwater– Recharge contribution from other aquifers to the LTA– Measure standard aquifer properties and their variability– Identify natural recharge areas under current hydrologic conditions– Identify recharge areas under increase utilization– How additional pumping may impact the aquifer and surface water

Installation of Groundwater Monitoring Wells
Locations include– M&T Ranch– CSU Chico Farms– Hackett Property

Technical Steering Committee, November 8, 2010
Installation of Groundwater Monitoring WellsOverview
Multiple completion wells are used to assess interaction between distinct zones of Lower TuscanAdditional refinement of understanding
f b f h d lof subsurface hydrogeologyWells small diameter (2.5 inch) cannot be used as production wells.

Installation of Groundwater Monitoring Wells Drilling MethodsDual-Tube Reverse circulation– Depth discrete sampling
LithologyWater ProductionField testing of water qualityField testing of water quality
Flooded Reverse Circulation– Same as dual tube but uses a water column to assist
with cuttings recovery– Loose ability to assess water quality during drillingMud Rotary Reaming method– Allowed E-log and Caliper run for each borehole

Dual-ring Infiltrometer Testing
Seven site completedSoils types range from– Lower Tuscan Outcrop (Rock)– Soils Immediately overlying
Lower Tuscan– Thin Mapped alluvium
overlying Lower Tuscan– Thin soil overlying Upper

Dual Ring Infiltrometer Testing
Discussion– Variable results– Will Compare to published soils data for each site– Flow is not necessarily vertical. Once soil column saturated horizontal
flow is observedflow is observed– Difficult driving– Variable soil thickness

Temperature Gradient Well Installation
Discussion– Mill Creek – Lower Tuscan rock outcrop Test Location– Big Chico Creek – Lower Tuscan rock outcrop Test Location– Butte Creek – Thin alluvium over Lower TuscanPilot test the methodology at these locations to determine if appropriate.Wells currently installed at Mill Creek.– Two boreholes were advanced to 10 feet.– 5 feet from waters edge conditions were moist.– 25 feet from waters edge conditions were dry.

Next StepsWinter 2010 / Spring 2011 Schedule
Establish background monitoring of Groundwater levelsCollect stream discharge measurements and stage dataComplete gauge installation as access becomes available
25
Perform Pilot Test of Temperature gradient wellsReview existing Aquifer TestsPrepare for Aquifer Testing during Pumping season 2011.
