Microbiological Results From Testing The JAC PAC Dear Mr. MacNeal: Subject: Bacteriostatic Efficacy ofjac Pac Model fP-11OO-HT Water samples taken, before and after use by bathers, from a Kocohani Holdings Infinity six person hot tub equipped with the above sterilizer were analyzed for total and fecal coliforms and standard plate counts. Bacterial levels were determined following methods given by the Association of Official Analytical Chemists and Standard Methods for the Examination of Water and Wastewater. An initial sample was taken after the tub had been unused for two days. A second sample was taken after 2.83 person hours (5 bathers for 35 minutes each ) exposure to bathers. Follow up samples were then taken at 1, 6 and 23 hours after exposure to bathers. The analytical results are shown in Table 1. All coliform organisms were killed within 1 hour after bather exposure. Standard plate counts were reduced to below pre-exposure levels within 6 hour after bather exposure.
