Primary activities in seasonal thermal energy storage (STES) involved field testing of high-temperature (> 100/sup 0/C (212/sup 0/F)) aquifer thermal energy storage (ATES) at St. Paul, monitoring of the University of Alabama Student Recreation Center in Tuscaloosa, Alabama, and limited numerical modeling efforts. The first long-cycle test at the University of Minnesota field test facility was completed. It consisted of approximately 59 days of heated water injection, 64 days of storage, and 58 days of heated water recovery. Chemistry of the recovered water was close to what was expected. Limited experimentation was done to characterize physical and chemical processes at the ATES test facility. A chill ATES monitoring project, initiated at the Student Recreation Center on the University of Alabama campus, continued during the reporting period. Numerical modeling efforts were continued at a minimum level to support field studies. The chill ATES facility at the University of Alabama Student Recreation Center was simulated with the Unconfined Aquifer Thermal Energy Storage (UCATES) model to examine the effect of different injection/recovery patterns on the system's thermal performance.
