Unknown about swimming pools and analysis of pool water

During the summer months, we swim, train, train, learn how to swim in what condition, how to clean or whether the pool managers take the necessary precautions come to mind many questions. As users, we can control this situation; How can we be sure of the cleanliness of the swimming pools?

Pool cleaning should be done periodically. It is very easy to get sick in the pools which do not have regular maintenance and cleaning. By cleaning the pool in certain periods, you will not encounter more permanent problems in the pool and you will have health and hygiene that relaxes your pool pleasure. Pool water analysis is of great importance in this sense. We need to examine whether the analysis is performed in the swimming pool we use.

According to the Regulation on the Amendment of the Regulation on Health Principles and Conditions to be Subject to Swimming Pools; In particular, hotel pool forwarders have to periodically analyze and analyze pool water. The analysis and limit values ​​of the analyzes that they have to do and have to do are as follows:

Table 1 Chemical Properties of Pool Water

Parameter	Analysis Range	Unit	Limit Values
			Lowest	Highest
Cyanuric acid(1)	Once a month	mg/L	-	100
Biguanid2			2	30
Hydrogen Peroxide(2)			40	80
pH (2)			6,5	7,8
Amonium (2)				0,5
Nitrite				0,5
Nitrate				50
Copper				1
Aluminum				0,2
Total alkalinity (2) (CaCO3)			30	180
Bound chlorine (3)				0,2
Indoor swimming pool water free chlorine(3)			1	1,5
Outdoor swimming pool water free chlorine 3			1	3
Free Chlorine (4)			0,3	0,6

^{___________________}

(1) It is used in pools where chlorinated compounds with stabilizers are used for disinfection of water.

(2) If hydrogen peroxide + biguanide is used for disinfection of water, hydrogen peroxide should be in the range of 40-80. In this case, pH 8.2, ammonium 1.5 and total alkalinity up to 220 are considered appropriate. Free chlorine measurement is not done in these pools, hydrogen peroxide and biguanide are measured.

(3) Chlorine and chlorinated compounds are used in disinfection of water.

(4) Ozone, UV, chlorine dioxide and other disinfection systems are used for disinfection of water.

NOTE: Hydrogen peroxide, biguanide and free chlorine measurements are made at the pool location.

Table 2 Physical Properties of Pool Water

Parameter	Analysis Range	Desired Value
Colour	Once a month	10 units as Pt / Co
turbidity	once a month	5 units as SiO2 or Jakson units or 0.5 units as NTU or FNU
Temperature (1)	once a month		Lowest	Highest
		Indoor pool	26 oC	28 oC
		Outdoor pool	26 oC	38    oC

⁽¹⁾ Temperature is measured by the pool.

 

Table 3 Microbiological Properties of Pool Water

Parameter	Recommended Method (1)	Analysis Frequency (2)	Limit Vues
Total number of colonies (germs)	TS EN ISO 6222	Once  month	200 CFU(3) /ml
Total coliform bacteria	TS EN ISO 9308-1		0/100 ml
Escherichia coli (E. Coli)	TS EN ISO 9308-1		0/100 ml
Pseudomonas aeruginosa	TS EN ISO 16266		0/100 ml

(1) In addition to the proposed method, laboratories may use another method, provided that their references are provided.

(2) The frequency of analysis should be twice a month during periods of intensive use of swimming pools.

(3) CFU Colony Forming Unit.

Temperture	Indoor Swimming Pool	At least 3 times a day, the first before the use of the pool and at intervals of 4 consecutive hours.	o C	26	28
	Outdoor Swimming Pool			26	38
Biguanid1			mg/L	2	30
Hydrogen Peroxide(1)			mg/L	40	80
pH (1)	Fresh water and sea water			6,5	7,8
	Indoor and Outdoor Pools

	Outdoor Swimming Pool		mg/L	1	3
Free Chlorine (3)	Indoor and Outdoor Pools		mg/L	0,3	0,6
Cyanuric acid(4)		Everyday	mg/L	--	100
Total alkalinity(1) (CaCO3)		Once a week	mg/L	30	180
Colour		Everyday	10 units as Pt / Co
Turbidity		Everyday	5 units as SiO2 or Jakson units or 0.5 units as NTU or FNU
