Concerns leveled over polluted floodwaters in Midwest
Human waste overflows, fertilizer runoff and floating propane tanks are raising concerns in the flooded Midwest but should not cause severe or long-term environmental problems, health officials say. Serious chemical pollution from factories and chemical plants "aren't concerns because we don't have many reports, just isolated cases and leaks," said Karen Timberlake, Wisconsin's secretary of Health and Family Services.
