05 September 2011, Tokyo Electric Power Company says it is growing concerned (finally) about the amount of radioactive water still building up in the basements of the reactor buildings.

TEPCo officials say even if they keep it from running off into the Pacific Ocean, it will eventually soak into the groundwater, which eventually runs into the Pacific Ocean.

To try and stop anymore contamination from hitting the ocean, TEPCo proposes to build a 800 meter (2,625 feet) long wall!  The wall will be made of huge iron pipes.

Each pipe, 22-meters (72 feet) long and 10 centimeters (4 inches) wide, will be installed deep below the sea bed to stop the flow of groundwater.

TEPCo says they will also attempt to use pumps to pump out contaminated water.  They hope to start building the wall by the end of the year, and think it will take two years to complete.
