Ofthe 36 lakes, 14 are in Dong Anh district, six are in Thach That district andsix are in Ba Vi district, said Phan Hoai Minh, deputy director of the company.The remaining ones are in Chương My, Gia Lam, Son Tay, Thanh Oai, Ung Hoa and MeLinh districts.

Minhsaid that in 2016, following proposals submitted by district and townauthorities, the company assessed the pollution level of 150 lakes on theoutskirts of the capital city. Of these, 140 lakes were severely contaminatedand needed urgent clean-ups to protect their bio-systems, safety levels and thesurroundings.

Thelakes have been cleaning using the Redoxy-3C technology from Germany. Expertsand local authorities have accessed the cleaned-up lakes and said that they areno longer smelly and animals are no longer dying.

Aftertreatment, the lakes have been handed over to local authorities for theirmanagement and maintenance.

“Thelakes on the outskirts usually have a lot of water ferns, so we facedifficulties in doing the treatment. I hope that local authorities will sendcleaners to tidy up the rubbish to facilitate the lake treatment process,” Minhsaid, adding that another 34 lakes in the suburban area are on the clean-uplist, and that 12 of them would be fixed this month.-VNA
