While the big bad corporation has often been the offender in many of the world’s greatest environmental disasters, in the case of the mass poisoning at Camp Lejeune the culprit is a revered institution: the US Marine Corps.

He also raises far-reaching and ominous questions about widespread contamination on US military bases worldwide.
