Environment workers use Redoxy3C to treat polluted water on many lakes in Hanoi
According to the Hanoi People's Committee, there have been doubts about the effectiveness of Redoxy3C which is imported from Germany to treat polluted lakes in the city over the past two years.
"Doubts have risen among the public although the Hanoi Sewerage And Drainage Company reported that after two years using Redoxy3C, in 87 of 125 heavily polluted lakes in the city have been saved with water quality meeting the standard set by the Ministry of Natural Resources and Environment,” the committee said.
The substance was introduced to use for Hanoi lakes by the city's vice chairman of Nguyen The Hung after consulting Watch Water Germany Company from Germany.
Tonnes of REDOXY-3C had been sprayed on West Lake to treat pollution after the mass fish deaths in 2016. The substance was continued to be used in many polluted lakes in the capital.
Chung requested the inspection team to file a report on the issue within 45 days. Dtinews
