Hi,
I live at Earthaven Ecovillage and I just tested my spring water - PH 4! Several neighbors and my family use spring water that fills a 10,000 gal tank then gravity feeds to our houses and gardens. All the soils in this area of North Carolina are very acidic at around 4.5 - 6.5 PH.
I wondered if we could put brown marble or limestone rocks/gravel in our tank to help raise the PH? Does anyone know if this would work? Heavy metals? Are there health concerns with this idea? I've been searching the internet the last day and haven't found any info or product that would help alkalize large quantities of water, so any creative ideas or input would be greatly appreciated. Thanks!
Travis
