Since reaching a historical high in 2008, U.S. coal production plummeted by a third in the ensuing decade. Companies accounting for nearly half the coal dug across the country declared for bankruptcy in 2015 and 2016, and President Donald Trump's rhetorical ending of the ‚Äúwar on coal‚Äù has shown no meaningful signs of reviving the industry. With the writing on the wall for U.S. coal, I investigated the system meant to guarantee that funds are available to pay for environmental cleanup. I built first-of-their-kind databases to determine how much money was in this system, where it was held and other trends in the industry such as levels of oversight and types of post-mining land uses. A combination of data analysis and ground-level reporting from around the country resulted in stories that showed myriad issues in protecting cleanup funds, which result in scarred land and polluted air and water.
