When requested, results of such analysis must be made available to the Utah Department of Health, Division of Epidemiology and Laboratory Services, Bureau of Environmental Services.

(b) When less than two samples per month are collected and submitted for bacteriological analysis, the local health department shall conduct a follow-up inspection for each failing sample to identify the causes for the sample failure. This follow-up shall be conducted within three working days following the reporting of the sample failure to the local health department.

(10) Not more than 15 percent of the samples covering a four month period of time may fail bacteriological quality standards. A seasonal or other pool in operation less than four months may only fail bacteriological quality standards with an initial pre-opening sample prior to the opening of the operating season. If a seasonal or other pool in operation less than four months in a year is sampled on a once per month basis, then failure of any bacteriological water quality sample shall require submission of a second sample within one working day after the sample report has been received.

(a) A pool water sample fails bacteriological quality standards if it:

(i) contains more than 200 bacteria per milliliter, as determined by the standard 35 degrees Celsius heterotrophic plate count or;

(ii) shows positive test, confirmed test, for coliform organisms in any of the five 10-milliliter portions of a sample; or

(iii) contains more than 1.0 coliform organisms per 50 ml if the membrane filter test is used.

(11) Pool water temperatures, excluding spas and special purpose pools, must meet the following requirements:

(a) Pool water temperatures for general use must be within the range of 82 degrees Fahrenheit, 27.8 degrees Celsius, to 86 degrees Fahrenheit, 30.0 degrees Celsius.

(b) The water in a pool dedicated primarily for swim training and high exertion activities must be within the temperature range of 78 degrees Fahrenheit, 25.6 degrees Celsius, to 82 degrees Fahrenheit, 27.8 degrees Celsius to reduce safety hazards associated with hyperthermia.

(c) The minimum water temperature for a pool is 78 degrees Fahrenheit, 25.6 degrees Celsius.

(d) The local health department may grant an exemption to the pool water temperature requirements for a special purpose pool including a cold plunge pool, but may not exempt maximum hot water temperatures for a spa pool.

(12) Total dissolved solids in a public pool may not exceed 2,500 ppm.

(13) Total alkalinity must be with the range from 100-125 ppm for plaster pools, 80-150 ppm for a spa pool, and 125-150 ppm for a painted or fiberglass pool.

(14) A calcium hardness of at least 200 ppm must be maintained.

(15) The saturation index value of the pool water must be within the range of positive 0.3 and minus 0.3. The saturation index shall be calculated in accordance with Table 6.

Formula for Calculating the Saturation Index: SI = pH + TF + CF + AF - 12.1 where SI means saturation index, TF means temperature factor, CF means calcium factor, and AF means alkalinity factor.

(5) splash pools must meet the following depth requirements:

(a) The depth of a water slide splash pool at the end of a horizontally oriented slide flume exit must be at least three feet, 9.14 cm, but may be required to be deeper if the pool design incorporates special features that may increase risks to bathers as determined by the department.

(b) The depth must be maintained in front of the flume for a distance of at least 20 feet, 6.10 meters, from which point the splash pool floor may have a constant slope upward. Slopes may not be designed or constructed steeper than a 1 to 10 ratio.

(c) The operating water depth of a vehicle slide splash pool, at the flume exit, must be a minimum of 3 feet 6 inches, 1.07 meters. This depth must be maintained to the point at which forward travel of the vehicle ends. From the point at which forward travel ends, the floor may have a constant upward slope to the pool exit at a ratio not to exceed 1 to 10.
