The recent media spotlight on ducks contaminated with toxic chemicals from steel slag dumped at a site in Kaohsiung County has prompted the central government and local government agencies to step up checks and start investigations over other possibly polluted locations left behind by the county’s steel industry.
While these measures promise to clear up the problem, critics said the real culprits have yet to be caught, while the corporations behind the pollution haven’t been found, adding that there may be more polluted locations that haven’t been checked.
There is a problem with all ducks that were raised on a polluted farm in Daliao Township (大寮), Kaohsiung County, that was closed by the Environmental Protection Administration (EPA) on Nov. 7. EPA officials culled 9,000 ducks there on Wednesday, but critics said all ducks that were raised on the site prior to that were also contaminated.
Environmental groups led by Huang Huan-chang (黃煥彰), an environmental activist and the organizer of an environmental protection program at Tainan Community University who tipped off investigators about the polluted farm, said they had seen ducks on the farm since 2006.
Huang said he brought officials from the EPA to the farm on July 22, more than two weeks before operators said they began raising ducks.
After showing reporters picture evidence, Huang said that he “absolutely guarantees that the ducks have [been sold] on the marketplace” despite the farm operator’s denial.
However, the problem isn’t with the farm owners that have allegedly been sold chemical-tainted ducks on the market, Huang said, adding that it seems their denial that they knew the land was contaminated when they rented it from Uni-President Enterprises was likely to be true.
Instead, the problem is how to clean all the polluted land in Daliao, he said. Huang, who has long taken an interest in contaminated land, said another list of polluted locations would soon be released.
Land contamination comes from improper disposal of hazardous waste or in the duck farm’s case — the illegal dumping of steel furnace slag and foundry ash. These pollutants come from factories and plants that produce waste by the truckloads and then ask disposal companies to haul it away, often turning a blind eye in the process, said Chao Jui-kuang (晁瑞光), environmental and natural sciences manager at Tainan Community University.
Chao worked with Huang in investigating other locations contaminated by furnace slag.
EPA Environmental Health and Pollutant Management Director Wang Jiunn-iuan (王俊淵) said the reason there is so much contaminated land is mainly because of illegal dumping by the disposal companies before more effective management methods were introduced in 2001.
Although laws were already in place, they were not enforced, he said. Only when the management systems of hazardous waste disposal trucks were digitized in 2002 did illegal dumping begin to subside, he said. Currently, the EPA requires hazardous waste disposal trucks to be outfitted with Global Positioning Systems (GPS) to track their locations at all times. This has greatly reduced the amount of illegal dumping, Wang said.
However, while illegal dumping has been reduced, the bigger problem is that no one knew about Daliao’s contaminated duck farm — which is at the origin of the media storm about contaminated ducks — until after Huang learned about the contamination by chance.
