It’s day 2 of the 2014 YMCA Short Course National Championships at the Greensboro Aquatic Center in Greensboro, North Carolina, and the air is still clear and fresh inside the pool.
Reports on deck are that the air is “even better” than night 1; of course, this could be some sort of perception bias, as there’s no good test available to measure the harmful chloramines in the air, but suffice it to say, there has been virtually no complaint that we’ve heard of through two days. On Wednesday, we’ve also been told that competitors can “smell the pool,” but that the bad air isn’t recirculating – which is the key strategy that prevents the burning eyes, the coughing, and the wheezing.
Now, a quick lesson on pool chemistry, because the situation isn’t entirely unchanged from the meet’s first day. Routine water tests done by the meet’s staff showed on Wednesday that the “combined chlorine” level in the separate warmup pool have risen since Tuesday. “Combined chlorine” is essentially cholarmines that are waterbound – they haven’t been released into the air yet. They aren’t harmful as they’re not being inhaled when they’re in the water, but they can mean pending doom for air quality.
These elevated levels of combined chlorine imply that there’s more organic matter in the pool – either sweat, or more swimmers have begun urinating in the water again.
These elevated levels imply that they should be followed by a bigger release of chlormaines, but as of Wednesday afternoon, the air felt clean. This implies that the special “major event unit” that Paddock Evacuator brought in seems to be doing its job magnificently in support of the primary installed unit.
We will continue to monitor this situation throughout the week. Keep in mind that one of the problems at Winter Juniors was that there were “dead zones” that were much worse than other areas of the pool; if you’re having a different experience than the above, let us know where in the comments and we’ll investigate further.
