Summary:

Potable water for the Shuttle orbiter is generated as a by-product of electricity production by the fuel cells. Water from the fuel cells flows through a Microbial Check Valve (MCV), which releases biocidal iodine into the water before it enters one of four storage tanks. Potable water is dispensed on-orbit at the rehydration unit of the galley. Due to crew health concerns, iodine removal hardware is installed in the chilled water inlet line to the galley to remove the iodine from the potable water before it is consumed by the crew. The Shuttle water system is sampled to ensure water quality is maintained during all operational phases from the disinfection of the ground servicing equipment through the completion of each mission. This paper describes and summarizes the Shuttle water quality requirements, the servicing of the Shuttle water system, the collection and analysis of Shuttle water samples, and the results of the analyses. The analytical results show that potable water consumed on orbit meets the Shuttle potable water quality requirements
