A log sheet or register should be used to record the results of every test performed at a swimming pool, spa pool or pool complex. The keeping of complete and accurate records is a professional activity and can be used to demonstrate competency in pool operations. Log books containing all of the log sheets should be maintained in a register for assessment of any technical issues and problems that may arise. Log sheets tend to be designed specifically for each premises and location.
Where automated in-line tests are recorded electronically, these should be downloaded monthly and kept with any other records. It is also possible to represent the data graphically which may add further meaning to the results. For example, free chlorine may be graphed against bather loads.
The following items may be included in a log sheet and those items marked with an "#" are essential. One person should be responsible for pool testing and recording of results each working shift and the log sheet should bear their name. A sample log sheet is available at the NSW Health swimming pool website and may also be obtained in MS Word format from NSW Health.
• # date and time of test
• # disinfectant concentrations (and oxidation-reduction potential ORP)
• # pH
• # total alkalinity
• # temperature
• bathing loads
• operational comments
• total dissolved solids (TDS)
• cyanuric acid concentration
• water meter reading
• electricity meter readings
• admission data
• dose settings
• mechanical maintenance items
• chemical usage and stocks on hand
• water balance
The Public Swimming Pool and Spa Pool Advisory Document provides detailed explanations and information on disinfection, pool chemistry, risk assessment and other issues relevant to swimming pool operation. It may be found at the NSW Health swimming pool web site at:
Public swimming pool issues may be discussed with an environmental health officer at a local Public Health Unit: http://www.health.nsw.gov.au/PublicHealth/Infectious/phus.aspor at your local council.
