The chemical spill in West Virginia may seem to many like a rare catastrophe, and the sheer scope of a man-made calamity that could deprive hundreds of thousands of drinking water for days will naturally garner widespread attention. Perhaps even more alarming is that this type of thing happens all the time. Even a quick dig through U.S. media reports and other data find no shortage of spills:
• An analysis by CBS found more than 6,500 domestic incidents in 2010 alone. Considering spills, leaks, fires, and accidents, an average of 18 per day took place in a single year.
