Fourteen family farms in the central province of Quang Ngai have asked a local company to pay VND440 million (US$23,127) in compensations for killing their ducks with untreated wastewater.
The provincial animal health department had previously concluded that some 3,000 ducks in Tinh Khe Commune died early this month because they ate fish and drank water from the Tra Khuc River, which had been polluted with untreated draff wastewater from the Quang Ngai Sugar Joint-stock Company's brewery.
The company was placed under investigation after some two tons of marine creatures like fish and crabs were found dead in the river on May 3 and 4.
In recent meetings with Quang Ngai Department of Natural Resources and Environment, the company said 3,000 cubic meters of wastewater was discharged to the river through a hole in its wastewater tank, news website Dan Tri reported.
Huynh Nam Kha, chief inspectorate of the environment department, told the news source that they have transferred the case to provincial police for further investigation.
Quang Ngai police said on Wednesday they have sent samples of wastewater and the river's water to calculate the extent of pollution.
After the police complete their investigation, the company will be asked to pay due compensation, Kha said.
The sugar company's suggestion to "support" affected farmers in accordance with "social security" was rejected by farmers and local authorities at a meeting on May 8.
The company also planned to move its brewery to an industrial zone in Duc Pho District, but hundreds of people there submitted their objection to local authorities.
