Rainwater Catchment and Filter

OH brother do you have it WRONG
Every raindrop that forms does so by condensing onto microscopic particles: dust, bacteria, viruses, etc. etc. etc. Without such 'nucleation sites' the water vapor would not 'condense'. There are approximately 35000 particles (0,001 - 1.0uM) per cubic ft In 'pure' air. The 'natural' pH of rainwater is slightly acidic to mildly acidic (5-6pH) Water that falls to earth and enters the underground aquifers does so by perculation through the soils, sand, porous rock ..... which filters the water !!!!!!!!! (but not the 'background' chemicals). Rainwater direct from the sky should be filtered to 3uM to remove fungal spores, (probably) 0,45uM to remove bacteria and bacterial spores; but, can also use common chemical disinfection by adding approx. 1 part per million of chlorine (from 5% clorox, etc.) article . com, Mark wrote: 2462 wrote: There is no valid reason for believing that rainwater will be clean and fit to drink.

There is no valid reason for believing that rainwater will be clean
and fit to drink. Well, all water we drink was rainwater at one time or another, wasn't it? Of course, once it's collected and stored, there's possibility of biotic growth, so it should be disinfected. But, if you open your mouth skyward when it's raining, I suspect it's as clean a water as you can get. What completely nonsensical "reasoning". Suspect as much as you want. But if you think rainwater "is as clean a water as you can get" you have no knowledge of water quality - at all. Quote from rainwater.com: "Rainwater is a renewable, sustainable and a high quality water source for your home or cottage. Baloney. Anf microbes are the least of the problems with rainwater. The industrail and other human generated chemical pollutants are the real problems. And depending on exactly where you are they can be very, very significant. |
