If you're one of the millions headed for some exercise at an indoor pool this winter, the experts say there are a few things you should keep in mind. If you smell traces of chlorine, or if your eyes begin to burn, you may want to skip that morning swim. That so-called "chlorine smell" often associated with indoor pools is actually the result of chloramines, a build-up of irritants in the water and air. These irritants can cause everything from itchy eyes, to wheezing, and even asthma.
The good news? New technology is helping to eliminate these threats. Ultraviolet light not only helps to disinfect water and kill bacteria, it also helps to destroy potentially harmful chloramines. Likewise, automated monitoring systems from companies like Siemens can keep tabs on ph levels and provide a demand-based chlorine feed.
