- Dr. Ken Buesseler, Woods Hole Oceanographic Institution oceanographer: Japan, in particular, has lost trust in their government — certainly TEPCO, the operators — for communicating the truth [...] They have problems with storage of waste on site, no end — I guess they have designed a cleanup system called ALPS to purify those tanks but they’ve done things just even a few weeks ago to bypass, taking water from the ground… and within a week or two then had to report that those waters were contaminated. There’s a continued series of problems of that site.
