VietNamNet Bridge - Environmental police caught Sonadezi Service JS Company, a state-owned waste-treatment plant in the southern province of Dong Nai Province, discharging poorly-treated wastewater into a canal that flows into the Dong Nai River.
Sonadezi, situated in Long Thanh Industrial Park is in charge of handling wastewater from 42 enterprises in the park. The company’s law-breaking act was uncovered in early August 4 by a team from the Ministry of Public Security’s Anti-Environmental Crime Prevention and Control Department.

On the night of August 3, the plant released about 9,300 cubic meters of black wastewater with stinking odor into the canal which is the main water supply for about 500 hectares of farmland in the district’s Tam An commune, police said. The police found a sewerage system buried underground serving to unload the wastes from the plant into the river.

Chu Thanh Son, deputy general director of the Industrial Parks Development Corporation – the parent company of Sonadezi, said the plant operates in accordance with regulations by the Ministry of Natural Resources and Environment.

The plant treats wastewater released from 80 percent of the textile and dying companies in the Industrial Park and during the treatment process, and it has not met some criteria, like color and temperature of the treated waste, he admitted.

“It is difficult to treat colored wastes from the textile and dying factories. Frankly speaking, the current standard on wastewater’s color is so strict that we could not meet it although we have treated the wastes several times over,” he explained.

“The ministry has instructed us to improve our treatment methods and set a deadline of June 2012 for completion of the improvement,” he said.

Environmental police have also caught Taiwanese-owned Nan Pao Resins Vietnam Co., Ltd in the southern province of Binh Duong unsafely storing harmful wastes, having no exhaust fume treatment facility, and mismanaging industrial wastewater.

At an inspection on August 5, the police detected a large quantity of harmful solid and liquid wastes, used printing-ink cartridges, substandard glue, out-of-date solvent, discarded plastic tanks, and others. All of them were placed outdoors inside the company, the inspectors said.

The quantity of the wastes was estimated at 30 tons, according to Huang Chin Keng, general director of the company, which is situated in the Song Than II Industrial Park in Di An town.

The company was also found not having a treatment system for exhaust fumes from its two waste-treatment boilers which handle a combined 6 tons of wastes per hour. The stinking odor from the exhaust fumes pervaded the air inside and outside the company, police said. In addition, the company’s industrial wastewater was found overflowing from its tank to the ground.

The police made a report on the findings and took samples of the wastewater for testing.

The Taiwanese-owned company manufactures glue for shoe-making and PU plastics.
