§ 92.25  DISINFECTION; WATER QUALITY.
   (A)   Bacteriological sampling shall start at least one week prior to the opening of the public pool.
   (B)   Public pools, when open for use, shall be continuously and automatically disinfected with a chemical which imparts an easily measured, free residual.
   (C)   A free residual of the disinfectant chemical shall be maintained throughout the pool at concentrations in accordance with the following:

   (D)   Whenever the residual disinfectant level falls below the minimum designated level, the public pool shall be closed and kept free of bathers until that minimum level has been restored.
   (E)   The Department may accept other disinfecting materials or methods when such materials or methods have been adequately demonstrated to provide a satisfactory residual effect which is easily measured and to be otherwise equally effective under conditions of use or halogen concentrations as required in division (B) or as a secondary disinfectant to be used in conjunction with a halogen. Such materials and methods shall not be dangerous to public health, create objectable physiological effects, or impart toxic properties to the water. The use of gaseous (elemental) chlorine as a disinfectant in public pools is prohibited.
   (F)   Water shall be manually tested shall be collected from the deepest part of the pool maintaining distance from inlets and outlets.
   (G)   A test kit to measure the concentration of free available disinfectant, accurate within 0.5 mg/L and covering a minimum range of 0.5 mg/L to 10 mg/L, shall be used at each public pool. Reagents shall have a mark of receipt on them and used within the timeframe of the manufacturer specifications.
   (H)   Public pool water shall be maintained in an alkaline condition as indicated by a pH of not less than 7.2 and not over 7.8. A pH test kit accurate to the nearest 0.2 pH unit and covering a minimum range of 7.0 to 8.0 pH units shall be provided at each public pool. The alkalinity of the water in public pools shall be maintained at a level of at least 80 mg/L as titrated to the methyl orange end point.
   (I)   The recirculation system for a public spray ground shall be maintained in condition to recirculate the volume of water every six hours. All other pools will comply with the required amount of turnover hours stated in Rule 410 I.A.C. 6-2.1-32. A device shall be provided to measure the flow of the water through the recirculation system. Such device shall be located where it is accessible and easily read. The water from the spray pad treatment system cannot be combined/circulated with water from other aquatic facilities such as swimming pools, water slides, or wave pools. The spray pad treatment tank filtration, circulation and spray pad chemical disinfection equipment must operate 24 hours a day.
   (J)   The temperature of a public spa water shall not exceed 104 degrees Fahrenheit or 40 degrees Celsius. A thermometer capable of accurately measuring temperature in the range of 80 degrees Fahrenheit or 27 degrees Celsius to 120 degrees Fahrenheit or 49 degrees Celsius shall be provided at each public spa facility. The thermostat for controlling the water temperature of a public spa shall be located in such a way that it cannot be adjusted by the customers.
