Glyphosate is being found in US drinking water too: - https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5486281/ - https://www.health.state.mn.us/communities/environment/risk/... The common message is Glyphosate has a very short (ish) half life in soil. What happens when it enters the water table first?
It seems like the half-life in water is less than that in soil: >* From literature studies, glyphosate’s half-life in surface waters and soil ranges from 2 to 91 days and from 2 to 215 days, respectively (Battaglin et al. 2014; Castro Berman et al. 2018). * https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8827352/
According to new research from Duke University, while it was always thought that glyphosate would break down very quickly in the environment, it seems to stick around a lot longer than we expected when it complexes in hard water.
This new research found that when glyphosate encounters certain trace metal ions that make water hard—like magnesium and calcium—glyphosate-metal ion complexes can form. Those complexes can persist up to 7 years in water and 22 years in soil.
