ADVANCE FOR USE SUNDAY, MAY 19, 2013 AND THEREAFTER - Environmental engineer Bob Lowder stands outside a "pump and treat" facility on the Marine base at Camp Lejeune, N.C. on Wednesday, Feb. 27, 2013. The sprawling installation is the site of one of the worst drinking water contaminations in U.S. history. The worst of the contamination occurred during the height of the Cold War. But records suggest that toxic substances began leaking - or were being intentionally dumped - into the ground almost immediately after the Department of War carved a spot for the 1st Marine Division out of the coastal pine forest at the mouth of the New River in late 1941.
