Congressional committee to ask ‘why’ coal ash spills occur
A congressional committee will focus on why a large Tennessee Valley Authority (TVA) coal ash impoundment failed last December, which resulted in one of the largest environmental disasters in U.S. history, according to News Channel 5. The breach caused more than a billion gallons of coal ash sludge to spill on to 300 acres of an east Tennessee community, destroying homes and damaging property in its wake. Coal ash contains dangerous toxins such as arsenic and lead which can contribute to serious health problems such as cancer, liver damage and neurological problems.
