Health and Safety
• Chemical balances are critical to the sanitation
of swimming pools.
– Dangerous to swimmers
– Cause damage to pool equipment
Health and Safety
• Monitoring the chemicals is very important.
– Chlorine and pH levels
• Hypochlorous acid (HClO) is the “active
chemical” used in pool water (Baxter 1).

m/pool-sanitation.html
Chemical Balances
HClO <=====> H+ + ClO–.
• pH range is 7.2-7.8 (Reiff 1).
• Low pH level:
– HClO concentration is too high
• High pH level:
– HClO concentration is too low
Chemical Balances
HClO <=====> H+ + ClO–.
• pH level is low:
– Too much HClO leads to compoundsthat are
harmful to swimmers.
– Can cause damage to the equipment used for
swimming pools.
(Baxter 1)
Chemical Balances
HClO <=====> H+ + ClO–.
• pH level is high:
– Low concentration of HClO means the chemical
isn’t affective.
– HClO no longer kills the microbes.
(Baxter 1)
