Every living organism needs water to survive, so keeping water clean from pollutants is something that concerns each and every one of us. However, it is an issue of special concern to agrochemical companies and to growers who strive to balance their need for effective weed control with safety for the environment. That’s were paraquat comes in. Comprehensive monitoring around the world confirms that paraquat does not contaminate ground water.
In their RED facts document, the US EPA concluded that “paraquat is not expected or considered to be a groundwater concern from normal paraquat dichloride use patterns” (US EPA, 1997).
Recent studies in France continue to confirm this assessment. The French monitoring of the ground and surface water is one of the best in the world and it has not detected any paraquat in its systems in almost a decade.
This held true in the most recent edition of “Les pesticides dans les eaux,” an annual national report on water contamination by pesticides. In the report, which uses 2002 data, researchers identified the main molecules quantified in surface waters in 2002, across all networks (page 22, figure 10). The top five molecules listed were: atrazine, AMPA, atrazine déséthyl, glyphosate, and diuron.
Once again, paraquat was not detected.
The reason? Binding.
