Just so you know, the main concern from the disaster preparedness folks was the disinfection by-products in the pool. They basically had a typical pool tested in a similar way that is done for drinking water and nothing could be done to it regarding filtration or boiling to get it to meet the standards for drinking water (ignoring the obviously greater salt level). Obviously, distillation might work (unless there are too many volatile disinfection by-products) and perhaps they are being overly conservative, but that was their biggest concern.
Remember that the more complex organic compounds aren't fully oxidized by chlorine yet some of them combine with chlorine. Though only some are volatile and most do not get absorbed through the skin, drinking the water is another matter. Personally, I don't think it's a problem for a short-term exposure, especially when the alternative is dehydration, but I wanted to at least let you know their concern.
