Aquifer storage and recovery (ASR) has become a major component in numerous water supply
initiatives, particularly in Florida. Despite the recent focus and reliance on ASR, there have been
challenges due to undesirable water chemistry changes in the storage zone aquifer, specifically,
arsenic dissolution and subsequent detection in recovered water above the drinking water
standard of 10 micrograms per liter (µg/L). The purpose of this study was to select engineering
design parameters for log-removal of dissolved oxygen for a degasification pretreatment system
that would minimize the leaching potential of aquifer materials at an ASR project sited in the
Upper Floridan aquifer. The basis of selection of design criteria was from results of a simple
geochemical model used to evaluate geochemical conditions resulting from injection of treated
recharge water. The final pretreatment system design was to include provisions for 2-log removal
of dissolved oxygen from recharge water. Includes 30 references, tables, figures.
