“The concern about glyphosate is for long-term exposure. As most health agencies would say, a single portion would not cause deleterious effects. But think about eating popular foods such as oatmeal every day or almost every day – that's when, according to scientific assessments, such amounts of glyphosate might pose health harm.”

“The vast majority of community water systems meet legal standards. Yet the latest research shows that contaminants present in the water at those concentrations – perfectly legal – can still harm human health. We need to prioritize source water protection, to make sure that these contaminants don’t get into the drinking water supplies to begin with.”
