health conscious pool building
We recently built our dream house, carefully choosing everything that went into it, due to concerns about health, maintenance, and durability. In other words, we checked out the components of all the tile, wall board, paint, stain, doors, countertops, etc. to make sure that nothing contained added formaldehyde or other dangerous chemicals, that nothing contained pesticides (Microban, which is classified as a pesticide, will probably be banned eventually by the EPA, but it is in so many products now!), that nothing was manufactured in China, etc. We also made sure everything was easy to clean and durable because we are essentially lazy and don't want to spend a lot of time cleaning and/or replacing stuff. Now DH wants a pool with a hot tub and a built-in cover. We have so many health-related concerns, as we don't want to expose our children or ourselves to harmful substances. I have searched the Internet, but I haven't found a good source of information on this topic. For example, what are the various basin linings actually made of? Do harmful chemicals leach into the pool water? Which is the "purest" material? Would we have to sacrifice durability to get it? What about decking material? What is the safest way to sanitize the water? Are all the pool covers made of vinyl (ick!)? Does the pool cover fabric actually come in contact with the pool water? If weather is a major factor in determining which materials we use, it should be noted that we live in the desert southwest. It is very sunny and dry year-round, 95+ degrees during the summer months, and we will use the pool for about six months of the year (mid-April through mid-October). Any suggestions on the most health risk-averse way to construct this pool and hot tub would be greatly appreciated.
