Despite efforts to stop the contaminated water from spilling into the Pacific Ocean, Tokyo Electric Power Company, and the Japanese government, say contamination levels  just off the Fukushima coast are at highest point so far.

Iodine-131 has hit 88.5 becquerels per liter, 30km (18.6 miles) away from Fukushima Daiichi. Cesium-137 levels continue to climb as well, but are still under Japanese safe limits.
