re the risks can occur. The plan also includes the sampling sites, methods public health measures for managing pollution with legionella in slovenian swimming pools 125
of laboratory testing, the sampling frequency of the bathing water, and appro-
priate documentation. The management plan is drawn up in accordance by the
National Institute of Public Health (NIPH) (Official Gazette of the Republic of
Slovenia, no. 39/11, 64/11 – corr. and 59/15. Official Gazette of the Republic of
Slovenia, no. 88/03., Official Gazette of the Republic of Slovenia, no. 56/06. Of�-
ficial Gazette of the Republic of Slovenia, no.26/07).
The managers of the swimming pool have to be educated on functioning
of all of the systems in the swimming pool, where there is a potential risk. They
have to manage and maintain the pools, so that there is less risk of infection,
including Legionella. Security measures are carried out at the pool decks, de-
vices for cleaning, sanitary facilities, showers, hot baths, cooling towers and air
humidifiers. The control of Legionella contamination in the pools is in princi-
ple similar to the control for the supply of drinking water. We have to ensure
proper temperature of the hot and cold water (cold water below 20°C and the
warm water over 60°C), regular maintenance to prevent water retention with-
in devices, emptying the swimming pools, complete cleaning. On a daily basis
water in the pool should be replaced in an amount of at least 30 litter per bather.
In swimming pools with swirling warm water, we need to ensure a continuous
flow of water and replace at least half of the pool water daily (Official Gazette of
the Republic of Slovenia, no. 39/11, 64/11 – corr. and 59/15. Official Gazette of the
Republic of Slovenia, no. 88/03, Official Gazette of the Republic of Slovenia, no.
56/06. Official Gazette of the Republic of Slovenia, no. 26/07).
The prevention of microbiological and physico-chemical conditions, ap-
propriate for Legionella development, depends on the behavior of the bathers.
Before entering the pool, bathers need to shower their body and feet in disin-
fection pool. Children less than three years old should use swim diapers in the
pool. We recommend bathing caps and clean shoes (17, 18 19, 20). In swimming
pools with swirling hot water, urination, feces and food consumption of the
bathers are strictly prohibited. It is recommended to limit the number of visi-
tors per day. We have to follow or take into account the Slovenian policy ‘Rules
on minimum hygiene requirements, that must be met by baths and bathing in
the swimming pools’ (Official Gazette of the Republic of Slovenia, no. 39/11,
64/11 – corr. and 59/15. Official Gazette of the Republic of Slovenia, no. 88/03, Of-�
ficial Gazette of the Republic of Slovenia, no. 56/06. Official Gazette of the Re�-
public of Slovenia, no. 26/07).
Each pool must be equipped with devices for the continuous temperature
measurement, free and bonded chlorine, redox potential and pH of bathing
water. The values of all parameters should be checked once daily with a hand-
set instruments (Official Gazette of the Republic of Slovenia, no. 39/11, 64/11 –
