MH 108
I know data labs test water, but it cost about $120. The cheaper the test, odds are it will be less accurate.
"IF" you send to one of the Hulda Clark people, their syncrometer will tell you down to 3 trillionths per parts according to Clark. I had 5 water samples tested in Switzerland this method and I did not mark the bottles with anyhting but numbers and they did tell me which bottles were what and the only water that pasted the test was my per distilled water and it landed me their dewormer business.
You must always remember, your being sprayed daily with these same gases, so to me it is not worth double distilling the water or going further with it. Our air is full of it thanks to the fly boys paid with our tax money and they do know they are killing us and everyone should remember this when they know someone that flys for the airforce. Normally only rich kids make leutinets from westpoint and I think they asusme us poor folks need some thinning out.
