my biggest concern with a "natural pool" would be the "brain eating amoeba", Naegleria fowleri, that exists in warm bodies of water such are found in Florida, Texas, and other subtroipcal to tropical areas. It has also been found in unchlorinated swimming pools!
Most of the cases in the US reported to the CDC have occurred in southern states like Florida, Texas and Louisiana and most have occurred by people swimming in lakes but there is a case in Orlando where a young man died after contracting it at a Water Park Orlando Watersports Complex)!
Natural pools depend on the same types of bacterial and plant based biopurification processes that lakes do so I would be very cautious about their REAL safety!
