In a series from late last month, the Dallas Morning News discovered:
Even the best national data on chemical accidents is wrong nine times out of 10.
A Dallas Morning News analysis of more than 750,000 federal records found pervasive inaccuracies and holes in data on chemical accidents, such as the one in West that killed 15 people and injured more than 300.
In fact, no one at any level of government knows how often serious chemical accidents occur each year in the United States. And there is no plan in place for federal agencies to gather more accurate information.
It's a lengthy read, but worth the time.
