Levels of hazardous chemical pesticides in the nation’s groundwater are mostly on the decline, according to a new U.S. Geological Survey report. That should be good news for the 75% of Wyomingites who rely on private wells for drinking water. But Jay Feldman, executive director of the nonprofit Beyond Pesticides, said the study only looks at 22 pesticides — many of which are no longer being used, and did not measure their highly toxic replacements. “Some of the more modern chemicals that are of concern,” Feldman said, “including Roundup, glyphosate, 2,4-D, dicamba, paraquat — these are all highly hazardous chemicals that are simply not evaluated in this study.”
