It was news when a leak of methyl mercaptan killed four workers at a DuPont chemical plant in La Porte, Texas, November 15, 2014. Maps and data are available to any environmental journalists who want to know about similar hazards near them, thanks to Amanda Frank at the Center for Effective Government.

After Katrina, Louisiana may have hit the national spotlight for a time, but coastal communities elsewhere around the country will have to find their own answers to the question “Why does anyone still live there in harm’s way?” — even as more and more people move toward the coast and the water moves ever closer to them.

In the effort to help all coastal communities face with the realities that the Gulf of Mexico is their neighbor and sea level rise is inching up relentlessly, lessons can be learned from Louisiana as it works to adapt and to mitigate flood risk.

The Center for Effective Government has compiled an interactive mapping database of some of the most dangerous chemical facilities in the U.S., showing their proximity to schools. The group also mapped which Congressional districts contain the most schoolkids at risk.
