Baker City began using ASR in 2004 to supplement high demand municipal reserves. 1 ASR well injects up to 200 million gallons per year of treated water into a basaltic aquifer, partially bounded by tuffaceous sedimentary rocks.
Following obtained from the Oregon Water Resources Below Ground Storage Site Search:
Aquifer thickness (ft): 60
Hydraulic Conductivity (ft/day): 6-16
Transmissivity (ft/day) : 370-1000
Static Water Level (ft): n/a
Specific Capacity (gpm/ft): 16.5
