One in ten American schoolchildren study within one mile of a potentially dangerous chemical facility, according to the Center for Effective Government's latest interactive map, which we released yesterday. A year ago, the fertilizer facility explosion in West, TX, which destroyed one school and irreparably damaged two others, demonstrated the very real risk these facilities pose, especially to schools and students. Parents and community members need to better understand the risks these facilities pose and demand that facilities be as safe as possible.
