Water continues to flow into a large sinkhole on the Mosaic Co. property shown in this aerial photo Thursday, Sept. 29, 2016, in Mulberry, Fla. Neighbors of the huge sinkhole sending cascades of contaminated water and fertilizer plant waste into Florida's main drinking-water aquifer are fearful and fuming that it took weeks for them to be notified about the disaster. Many are still waiting anxiously for results from tests for radiation and toxic chemicals in their well water.
