Tokyo Electric Power Company officials say they will test the ocean for plutonium.  They have already found soil samples to be contaminated with the toxic isotope.

TEPCo official Matsumoto Junichi says because plutonium was found in the ground around Fukushima Daiichi, then it’s possible it is getting into the ocean.  They will check the ocean floor, because plutonium is heavier than other isotopes, and probably sank.
