Don't blame HVAC systems for bad air.(LETTERS)(Letter to the Editor)
I read with interest the article "The Air in There" (November/December 2004).
The air quality in an indoor swimming pool, waterpark or spa is not an air quality problem. It is a water quality problem.
As chlorine is added to water, hypochlorous acid (free chlorine) is formed. The free chlorine reacts with the waste brought in by the swimmers. Many reports suggest that 1 liter of bather waste is added per hour. Bather waste is the greatest amount of any chemical added daily to a typical pool--200 bathers equals 50 gallons (200 liters) of waste.
Waterparks may have as many as 200 plus bathers per hour, therefore the volume of waste quickly adds up and creates the odor and eye burn all too familiar with indoor swimming pools. The combined chlorine, which is formed by the free chlorine reacting with the bather waste, forms many compounds, some of which are hazardous to the swimmer and pool staff.
The removal of chloramines / trihalomethanes-chloroform / nitrogen trichloride is the greatest fiduciary responsibility that a pool operator has next to bacteriological cross infection. THMs have been determined to be carcinogenic and nitrogen trichloride causes stress corrosion in facilities--even on stainless steel.
