The EPA is considering the novel disposal plan in a pending ruling that may set a precedent for new ways to clean up Superfund sites. There is a lot more to this story than there is room for here. Congratulations to the Seattle Times and reporter Duff Wilson for breaking this story in the mainstream press. Radioactivity does not go away. Pesticide residues have harmful effects.
Some plants take up more or less of certain chemicals from the ground than others.
When the plants are eaten by animals, the toxins build up and multiply in their tissues. In conclusion, the Seattle Times coverage apparently did have an effect, because on August 7th regulators from all over the US convened to discuss the labeling of fertilizers. A panel of regulators and fertilizer executives was appointed to come up with a policy on labeling, and it was announced that it would be proposed in six weeks. We need to study the problem and have public reports on it, set up a system of notification and labels, and, as soon as possible stop the practice. Californian's who want to follow the issue should contact the State Department of Food and Agriculture.
