(62) "Organic Matter" means perspiration, urine, saliva, suntan oil, cosmetics, lotions, dead skin, and similar debris introduced to water by users and the environment. (63) "Orthotolidine (OTO)" means a colorless reagent that reacts with chlorine or bromine to produce a series of yellow-to-orange colors which indicate the amount of chlorine or bromine in water. (64) ““Oxidation Reduction Potential” means a measure of the tendency for a solution to either gain or lose electrons; higher (more positive) oxidation reduction potential indicates a more oxidative solution. (65) "Overflow System" means a system for the removal of pool/spa surface water through the use of overflows, surface skimmers and surface water collection systems of various design and manufacture. (66) “Patron” means a bather or other person or occupant at a public pool who may or may not have contact with water either through partial or total immersion. Patrons may not have contact with the water, but who might still be exposed to potential contamination from the facility’s air, surfaces, or aerosols. (67) “Peninsula / Wing Wall” means a structural projection into a pool intended to provide partial separation within the body of water. (68) "pH" means the negative log of the concentration of hydrogen ions. As pH is raised, more ionization occurs and chlorine disinfectants decrease in effectiveness. (69) "Pool" means any artificial water holding structure with a closed-loop circulation of water through a water treatment system with a return to the structure. (70) "Private Pool" means any constructed pool, permanent or non-portable, that serves a single-family dwelling and is used only by the residents of that dwelling and their guests. (71) “Public Swimming Pool" means any structure, chamber, or tank containing an artificial body of water shared and used by the public for swimming, diving, wading,
requirements of the Federation Internationale de Natation Amateur (FINA), U.S. Diving, National Federation of State High School Associations (NFSHSA), or similar authority. (7) Minimum Dimensions for Diving Portion of (a) Diagram showing points where dimensions are measured. Note that the shallow portion of the pool is not shown. Note: L4 is a minimum dimension to sufficient length opposite the board. This may of course be lengthened to form the shallow portion of the pool.

With multiple board installations minimum pool widths must be increased accordingly. - Deck Level Board to Pool Side 8' - 1 Meter Board to Pool Side 10' - 3 Board to Pool Side 11' - 1 or Deck Level Board to 3 Meter Board 10' - 1 Meter or Deck Level Board to another

(13) Wading Pool Water Depth. Wading pools constructed after adoption of this chapter shall be separate and physically set apart from beginning or shallow water areas of swimming pools by at least fifteen feet of deck.
