I just found my new favorite Green design blog! The Daily Green is a website dedicated to the latest green news, products and trends that I just spent the last hour on and could have stayed on for another! I just read this great article about Natural Swimming Pools, here is an excerpt from their article:
"Chlorine's damaging effects on hair are well known, but few people realize that a number of studies have linked inhalation of the chemical by swimmers to increased asthma rates (in fact a new Irish study published this April reported a significant link between the number of years a boy had been swimming and the likelihood of the child being wheezy in the past year.) A Norwegian study also documented an increased risk of wheezing among children who swim in pools before 6 months of age. Further, in an unpleasant reaction, pee and sweat in water can react with chlorine to form toxic breakdown products known as chloramines.
For health, environmental and aesthetic reasons, a lot of people have expressed interest in alternatives to chlorine pools, and luckily there are more and more options to get wet without smelling like cleaning products. A company called TechnoPure offers alternative pool systems that treat water by pumping it through a chamber containing coated titanium plates and copper and zinc ions. The units cost a relatively affordable $5,500. DEL Ozone makes ozone injectors that can reduce the need for chlorine up to 90% -- there's been one installed at the White House for years! Some systems rely on a combination of ozone and copper and silver ions, while others are saline, though saltwater pools result in the formation of chlorine in the water.
Managed properly, natural swimming pools have crystal clear water and require no chemicals to maintain, as they are self-cleaning mini-ecosystems. "You can drink the water if you want to, and you don't necessarily have to take a shower," says Morgan Brown of Idaho-based Whole Water Systems, LLC. The natural pools designer says the systems also have lower maintenance costs than conventional pools, and their installation costs are not much more than standard designs.
