> OG magazine warns against Roundup--Monsanto's claims to the contrary, it > does wind up in the water. At the risk of sounding "anti-organic" (which I'm not), to my knowledge Monsanto has never made any claims that Roundup cannot leach into water supplies. The fact is that glyphosate is highly adsorbed by most soils, and typically only very small amounts, if any, leach into groundwater when properly used. Even when some makes it into water bodies, it is further adsorbed and tightly bound to any organic matter in the water, where it is broken down via microbes in a few weeks' time. Because it breaks down, there's no bioaccumulation (as with DDT, PCP, etc). I rarely use the stuff myself, but when I need to, such as on poison ivy as did the poster of the above quote, I dont think it's polluting the water. I don't think even Greenpeace cites glyphosate as a water pollutant hazard. Dan Dixon
