Navy Resumes Sinking Old Ships: For the first time since 2010, the U.S. Navy will resume its practice of using old warships for target practice and sinking them in U.S. coastal waters. The practice, called Sinkex, was put on hold when conservation groups sued the Navy claiming that the sunken ships pollute the waters. The groups say that the ships should be recycled at a ship-breaking facility.

According to AP, the Navy has destroyed vessels for years with little or no oversight. But in 1999, the EPA ordered the Navy to document the toxic waste, such as polychlorinated biphenyls (PCBs)left on the doomed ships. But there is little oversight, as the Navy is ultimately in charge in estimating and reporting the pollutants onbaord.

The Navy says that the practice of forcibly sinking sinks provides valuable live-fire training for soldiers. The ships can be targeted from the air, ocean's surface or underwater, giving ship designers useful information about how to build better and stronger ships. Later this month, three inactive vessels — Kilauea, Niagara Falls and Concord — will be sent to a watery grave off Hawaii by torpedoes and bombs.
