- (1) The temperature of the pool water must be 106 degrees F or less.
- (2) The water must have sufficient clarity at all times so that a black disc, 6 inches in diameter, is readily visible when placed on a white field at the deepest point of the pool.
- (3) The pool water must be maintained at a pH of no less than 7.2 and not greater than 9.4.
(4) The pool must provide sufficient water volume exchange to produce an 8-hour turnover of the entire volume of pool water to waste. In addition:
- (a) the pool, and all surfaces that flow into the pool, must be drained, cleaned, and sanitized every 72 hours; or
- (b) the pool must be disinfected, and a chlorine residual of 1 to 3 parts per million or a bromine residual of 3 to 6 parts per million must be maintained in the pool at all times.
- (5) Signs must be prominently posted that specify pool rules and special health hazards associated with swimming or bathing in flow-through hot springs pools. The contents of the signs must be determined by department rule. The department, in developing rules under this section, shall consult with flow-through hot springs pool owners.
