Florence's flood waters contain plenty of danger, now coal ash, hog manure and other kinds of industrial wastes could be part of the mix.>> I'm Andy Sullivan in Columbia, South Carolina where officials are watching closely to see if Florence's rains will release a wide range of contaminants. Power provider Duke Energy has said that the downpour has already disrupted a landfill that holds waste from coal-burning power plants.
And with days of flooding on the horizon, more such incidents could be ahead.>> Last year, hurricane Harvey hammered Houston's petro-chemical industry, unleashing carcinogens and other dangerous toxins into neighborhoods. One chemical plant burned for days. Florence poses a different set of risks, sweeping through areas with nuclear waste, hazardous garbage and hundreds of hog farms holding lakes of urine and feces.
Those hog lagoons built to withstand less severe storms, not the sheets of rain brought by Florence. More than a dozen leaked two years ago during a milder hurricane.>> Duke Energy says the breach at its coal plant doesn't pose a risk to public health. But officials are already calling this a 1,000 year storm, the type of disaster that's sure to put other toxic facilities to the test.
