When environmental activist Carroll Cox charged last week that city crews had been illegally dumping tons of concrete rubble in Ma'ili'ili Stream and threatening the habitat of endangered wildlife, he called the unpermitted activity an outrage.

Yesterday, as he examined the city's attempt to clean up some of the mess at the Leeward O'ahu state waterway over the weekend, he got upset all over again.

"It is just as bad to hurry out here and clean it up without any specifications," grumbled Cox, who said city whistleblowers had tipped him off to some 300 truckloads of sidewalk concrete rubble that had been dumped in the stream over the past months.

While hundreds of tons of concrete remain in the channel, Cox said that heavy equipment had improperly removed what he estimated to be 110 tons of concrete from one edge of the stream on Saturday.
