I don't know what your water sample looks like, but it seems that you could have considerable levels of calcium in your water. Free cations in the water (hard water) reduces glyphosate's effectiveness. The only way that I know to truly sequester those cations is to use real ams. http://www.ag.ndsu.edu/weeds/weed-control-guides/nd-weed-control-gu...
