About 300 tonnes of contaminated water has been leaking into the sea daily since early in the crisis, which was caused by the 2011 earthquake and tsunami.

Japan’s government says it will step in to tackle contaminated water leaks at the country’s crippled nuclear plant, and is considering funding a multibillion-dollar project to fix the problem.

Government officials said on Wednesday about 300 tonnes of contaminated water has been leaking into the sea daily since early in the crisis, which was caused by the 2011 earthquake and tsunami. On Tuesday, the operator of the Fukushima plant said some of the water is seeping over or around an underground barrier it created by injecting chemicals into the soil that solidified into a wall.

Prime Minister Shinzo Abe said on Wednesday the government would intervene to tackle the problem.

Government officials said they’re considering funding a multibillion-dollar project to surround the reactor buildings with a wall to block underground water.
