Here’s some good for thought. According to Dr Elaine Ingham, an amazing soil biologist, municipalities coat the inside of pipes with cloramine to kill the bacteria and junk that attach to the inside of pipes. Then our drinking water of course is treated with chlorine. We have some small level of both chemicals in our drinking water and landscape water. She suggested using one drop of humic acid to 1 gallon of municipal water to neutralize the Chlorine and the chloramine. I’ve been doing this with my filtered drinking water at home for over a year now. It’s very inexpensive. I found liquid humid acid at a reasonable price at Walmart, and I have enough for several more years!
