A.
Water supply. The water used at all public bathing places for swimming or recreational bathing shall meet the bacteriological, chemical, physical and radiological standards of the Department of Environmental Resources.
B.
Circulation. Water shall be introduced to and withdrawn from the pool so as to provide uniform circulation and uniform disinfectant residual throughout the entire pool.
C.
Recirculation and filtration. All pools shall be provided with a recirculation and filtration system, except where there is a flow of water of the quality and quantity through the pool which at all times conforms to the provisions of this chapter.
D.
Turnover period. The turnover period for wading pools and swimming pools shall be governed by the D.E.R. permit.
E.
Clarity of pool. All water in the pool shall be sufficiently clear to permit a black disc, six inches in diameter on a white field, when placed on the bottom of the pool at the deepest point to be clearly visible from the runway or deck around the deep area of the pool.
F.
Overflow facilities. Overflow facilities shall be provided and water level in the pool maintained to effectively remove scum, debris or other floating matter.
G.
Swimming pool contamination. The water in a swimming pool or wading pool shall be considered contaminated when one of the following conditions exist:
(1)
More than one ten-milliliter portion of any sample shows a positive test for coliform organisms, when the multitube fermentation technique is used, or more than one coliform per 50 milliliters, when the membrane filter test is used.
(2)
Two consecutive samples show in a positive test for coliform organisms in any ten-milliliter portion of any sample, when the multitube fermentation technique is used, or more than one coliform per 50 milliliters, when the membrane filter is used.
(3)
Two of any 10 consecutive samples show a positive test for coliform organisms in any of the ten-milliliter portions of any sample, when the multitube fermentation technique is used, or more than one coliform per 50 milliliters, when the membrane filter test is used.
(4)
When any harmful level of disease-producing organisms, toxic chemicals or adverse physical conditions are present in the water.
H.
Disinfection of pool water. When chlorine or a hypochlorite compound is used for disinfection, the free chlorine residual in the water in all parts of the pool when in use shall be not less than one point zero (1.0) parts per million and the pH value of the water shall be not less than seven point two (7.2) and not more than eight point two (8.2). Other disinfecting materials or methods may be used after approval by the Department of Environmental Resources.
I.
Testing kits and procedure. Testing of pool water shall be performed and records kept in accordance with the following regulations:
(1)
Testing kits shall be provided for making the necessary tests for disinfectant residuals and pH and must be used according to the manufacturer's recommendations. Before opening for the day's activity and when the pool is in use, tests for disinfectant residuals and pH shall be made as follows: outdoor pools, every hour; and indoor pools, every two hours. The results of these tests shall be recorded on forms satisfactory to the Department of Community Development and shall be readily available at the pool side for inspection at any time.
(2)
The owner shall be responsible for the collection and examination of samples for the purity of the water used for swimming or bathing as required by Subsection J of this section. A bacteriological analysis shall be made at least once each week of a sample collected during the period of maximum use of the public bathing place. Additional analyses of additional samples shall be furnished by the licensee upon notification by the Community Development Department.
(3)
Copies of the reports of analyses shall be maintained by the licensee for at least two years and made available to the Community Development Department upon request.
J.
Laboratory testing. Laboratory tests of water shall be performed by competent personnel in accordance with the procedure provided in the current edition of Standard Methods for the Examination of Water and Wastewater, published jointly by the American Public Health Association and the American Water Works Association. Conformity to these standards shall be evidenced by a statement from the laboratory to such effect. Upon notification by the laboratory that pool water does not meet the standards for safe and sanitary swimming pool water, the pools shall be immediately closed to the public until the problem has been corrected. The Community Development Department shall be contacted when this occurs. This procedure is to be documented on the daily records indicating the corrective measures taken.
K.
Gas chlorination. Where gas chlorination equipment is installed at either outdoor or indoor pools, the equipment shall be housed in a separate room equipped with proper ventilation and all safety devices, as approved by the Pennsylvania Department of Environmental Resources in its permit.
