An enorm­ous reser­voir of ra­di­ation-con­tam­in­ated wa­ter be­neath the dis­abled Fukushi­ma atom­ic en­ergy plant in Ja­pan is on the verge of spill­ing in­to the Pa­cific Ocean, cre­at­ing a new ser­i­ous worry in the long-run­ning ef­fort of to con­tain the ra­dio­act­ive fal­lout from the 2011 atom­ic en­ergy dis­aster, the As­so­ci­ated Press re­por­ted on Fri­day.

Con­cerns about the ground­wa­ter crisis have been piled on top of the prob­lem dis­covered earli­er this week: An enorm­ous 80,000-gal­lon leak in one of the tanks that holds ra­dio­act­ive wa­ter used to cool the Fukushi­ma re­act­or cores.

“It’s like a haunted house, one thing hap­pen­ing after an­oth­er,” Shuni­chi Tana­ka, Nuc­le­ar Reg­u­la­tion Au­thor­ity chair­man, said in dis­cuss­ing the on­go­ing chal­lenges of deal­ing with fal­lout from the 2011 nuc­le­ar power cata­strophe.

It is not yet ap­par­ent just how en­vir­on­ment­ally harm­ful the seep­age of ra­dio­act­ive ground­wa­ter in­to the ocean will be, as the con­tam­in­a­tion will be watered down as it dis­perses through the ocean.

The ground­wa­ter be­came sul­lied when wa­ter used to cool the re­act­or cores, which was then stored in large sur­face con­tain­ers, seeped in­to the im­me­di­ate en­vir­on­ment.

The ra­dio­act­ive ground­wa­ter is leech­ing closer to the ocean at a pace of ap­prox­im­ately 13 feet every 30 days, ac­cord­ing to the Ja­pan Atom­ic En­ergy Agency.

“The wa­ter from that area is just about to reach the coast,” if it has not already ar­rived, At­sunao Marui, a ground­wa­ter spe­cial­ist with the Na­tion­al In­sti­tute of Ad­vanced In­dus­tri­al Sci­ence and Tech­no­logy, said in an in­ter­view. 

The Fukushi­ma re­act­or op­er­at­or, Tokyo Elec­tric Power Co., has sug­ges­ted ad­dress­ing the prob­lem by en­circ­ling the re­act­or areas with a 90-foot deep un­der­ground ice wall that would cool the nearby earth. However, that pro­posed solu­tion has yet to be tested and it would not be ready for de­ploy­ment be­fore 2015.

THE DETAILS

Donald Trump is planning to reverse an Obama-era order requiring that schools allow students to use the bathroom that coincides with their gender identity. Trump "has green-lighted the plan for the Justice Department and Education Department to send a “Dear Colleague” letter to schools rescinding the guidance." A case is going before the Supreme Court on March 28 in which Gavin Grimm, a transgender high school student, is suing his high school for forbidding him to use the men's room.

Trump Set To Issue New Travel Ban

THE DETAILS

Donald Trump is set to issue a new and more focused executive order clarifying the scope of his travel ban, hoping that the order will survive legal challenges. The new order would focus on the same seven countries, "but would only bar entry to those without a visa and who have never entered the United States before. Unlike the original order, people from those countries who already have permanent U.S. residency (green cards) or visas would not face any restrictions." Some lawyers believe the government will now have much stronger standing, though lawyers who challenged the initial order see the same core problems with the forthcoming ban.
