"Roads in Florida could soon include phosphogypsum — a radioactive waste material from the fertilizer industry — under a bill lawmakers have sent to Gov. Ron DeSantis.

Conservation groups are urging DeSantis to veto the bill, saying phosphogypsum would hurt water quality and put road construction crews at a higher risk of cancer.

The Environmental Protection Agency also has a say in the matter: The agency regulates phosphogypsum, and any plan to use it in roads would require a review, the EPA told NPR."
