The northern province of Hai Duong on Wednesday suspended operations of a Taiwanese-owned company found discharging untreated wastewater to a local river.
Tung Kuang Industrial Joint-stock Company, located in Cam Giang District, also had its license to treat wastewater and environmental certifications reovoked.
The aluminum frame manufacturer, which last week was found burying a pipe underground to release wastewater from its factories directly into to the Ghe River, will face more specific punishments this month, according to Hai Duong People's Committee.
Tung Kuang on the same day said it had been dumping untreated wastewater into the river since May, 2005 at the rate of some 250 cubic meters per day.
In a recent interview with the news website VnExpress the company's deputy general director Liu Chien Lin said Tung Kuang didn't restart the pipe, that was set up long before, until October, 2008 when it needed to save money after the global economic crisis.
According to provincial authorities, between 2007 and 2009 the company had been blacklisted for critical violations of environmental regulations.
