In a groundbreaking study published in Analytical and Bioanalytical Chemistry last month, researchers found that glyphosate, the active ingredient in the herbicide “Roundup,” is flowing freely into the groundwater in areas where it is being applied.

The researchers found that 41% of the 140 groundwater samples taken from Catalonia Spain, had levels beyond the limit of quantification – indicating that, despite manufacturer’s claims, it does not break down rapidly in the environment, and is accumulating there in concerning quantities.

Why Is Groundwater Contamination An Important Finding?

Groundwater is water located beneath the ground surface, that supplies aquifers, wells and springs.  If a chemical like glyphosate is mobile enough to get into the groundwater and is intrinsically resistant to being biodegraded (after all, it is being used to kill/degrade living things – not the other way around), significant environmental exposures to humans using the water are inevitable.

Keep in mind that glyphosate is considered by the EPA as a Class III toxic substance, fatal to an adult at 30 grams, and has been linked to over 20 adverse health effects in the peer-reviewed, biomedical literature.
