An Aug. 4 story about the USS Houston should have made it clear that Navy Lt. Cmdr. David Benham, a spokesman for Commander Submarine Force, U.S. Pacific Fleet in Hawaii, was responding to a question when he said "This is not nuclear waste. This is water," in regards to a possible radiation leak from the submarine. The Navy has said that very small amounts of radiation was found mixed with water during routine maintenance for the Guam-based submarine.
