The Healthier Swimming Directory has moved to piscinasana.wikidot.com in order to provide a clearer, searchable directory as well as interactive forums.
Why the change? Since this directory project began three years ago, the number of locations of safer, non- or low-chlorine pools listed here has expanded to the point that it's difficult to scan for locations in the blog format. The new directory will make it easier to find pools in your area.
An anonymous reader posted a comment that saltwater pools are not really chlorine-free; therefore, s/he thinks saltwater pools shouldn't be listed here. Saltwater pools do use salt to create chlorine which sanitizes the water. Interestingly though, some people report fewer allergic reactions to saltwater pools than to "normal" chlorine pools. There are also reports of no eye stinging or chlorine smells as occurs in "normal" chlorine pools.
I haven't found anything explaining why the saltwater process creates a less noxious environment than the more common chlorination methods, but there does appear to be a difference. Therefore, I think saltwater pools are still worth mentioning here as an alternative to the more harmful norm, but I will add a note to each entry that points out that they are not chlorine-free.
It's also worth pointing out that UV and ozone treated pools are often not chlorine-free though they have much lower chlorine levels than your average chlorinated pool.
Maybe I need to come up with a more accurate title for this directory. Any ideas?
