>The analysis honed in on geographic points where farm fields planted by corn growers are seen closely abutting waterways, and assumes that farmers sprayed their crops with atrazine, a common practice in the US Midwest. Though it could not be determined if atrazine was used on the fields, the chemical is applied to the majority of corn acres in the state, and the satellite images show clear pathways for the flow of farm chemicals off the fields and into waters. The biggest problem in any field of investigation and research is when people make assumptions In this case the whole issues begins by assuming the highly mobile (in soil -- iirc countless groundwater wells have recorded high levels present) herbicide was simply sprayed near the water way ... it's better to assume the dumb farmer isn't doing it right and ignored the requirement for a buffer ... and not heavens forbid, that the product is actually highly mobile, much more than mock up paddock trial experiments had demonstrated. Still those corn farmers are left with a problem, they rely on that herbicide but it would be better if it were less mobile, especially in sandier soils.
