NAGOYA (Kyodo) Regional coast guard officials searched Nippon Steel Corp.’s Nagoya works on allegations that high-density alkaline water leaked into the port.

The raid came after materials found in cracks at the steel works’ embankment tested positive for alkaline far above the safety levels set under the water pollution prevention law. The coast guard said no environmental damage has been reported.

Aichi prefectural officials said it is possible the materials in question leaked into the sea through the cracks after a chemical reaction occurred between iron slugs and groundwater.

Nippon Steel said the leak stopped after the completion of repair work on the cracks. The major steelmaker pledged to cooperate fully with the investigation.
