Therapists and instructors who work in a therapeutic pool setting are in the “water quality” business. They are offering health and fitness through the judicious application of water. Unfortunately, sometimes it’s the air that needs quality control. Pools which do not properly manage the levels of disinfection byproducts in the air can create respiratory minefields for staff (who are in the pool area the most) and clients (especially the very young and those with pre-existing conditions). One of the culprits in the air quality game is chloramines. Chloramines are a special type of combined chlorine that form in water and then end up hovering as a heavier-than-air gas immediately above the surface of the pool. 

Pools that are not properly ventilated, especially those with inadequate fresh air exchange, are prime environments for chloramine buildup, especially in winter when there is even less air exchange in an attempt to reduce heat loss. A pool which does not adequately eliminate this hovering blanket of gases will make it impossible for the chloramines in the pool to end up in the air, essentially creating a log jam effect. The end result? Respiratory effects.

One of the age-old questions is whether individuals with asthma are more likely to pick swimming as a sport or whether people who choose swimming as a sport just end up with asthma. It may be a combination of the two, but one thing is clear: Pool staff are no longer in just the water quality business. Air quality is the newest game in town.
