Despite numerous efforts and significant investments to improve the situation, rivers around Hanoi, such as the To Lich, Kim Nguu, and Nhue rivers, continue to suffer from severe pollution.The water remains black and foul-smelling day and night.

HCM City has been trying to eliminate water pollution in its canals in order to improve the living environment for local inhabitants.

Despite having spent thousands of billions of VND on cleaning major canals including Nhieu Loc- Thi Nghe, Tan Hoa - Lo Gom, and Tau Hu - Ben Nghe, authorities in HCM City have failed to curb pollution due to a lack of wastewater treatment plants.

The city’s authorities at all levels should cooperate and develop urgent plans to minimise the situation of wastewater overflowing into the sea.

Many HCM City canals have faced pollution again despite being upgraded.

Hanoi has treated water pollution at Nhue River, but the plan has not met the requirements. Meanwhile, urban area design plans along Lu and Set rivers in Thanh Xuan District are still under construction.

Hanoi's Tay Ho District People's Committee said on Monday that they were carrying out various measures to curb the mass fish deaths in West Lake.

Rapid urbanisation have led to increasing demand for housing and infrastructure. Consequently, ponds and lakes across the city have been filled to make room for construction.

West Lake in Hanoi has been polluted for many years and the problem doesn't seem to be getting any better.

The Ministry of Natural Resources and Environment’s (MONRE) tests show that the water of Hanoi’s West Lake is polluted.

The plan is to supply water from the Red river to improve quality of water in To Lich river which is severely contaminated for years.

The authorities in HCM City will spend billions of VND on waste collecting machines to clean rivers and canals in the city.

The 10-kilometre Nhieu Loc-Thi Nghe Canal running through districts 1, 3, Tan Binh, Phu Nhuan, and Binh Thanh in HCM City has become a popular place for sightseeing, taking photos and doing exercises.

The quality of surface water in many lakes and rivers in the north has improved, but 15 monitoring areas of 185 that have been monitored remain heavily polluted, mainly on the Cau and Nhue-Day rivers.

Rivers in northern provinces are severely polluted, according to the Vietnam Environment Administration's report released recently.

HCM City authorities have ordered the city Department of Natural Resources and Environment to work with agencies and district authorities to strictly monitor the discarding of litter and untreated sewage in canals in the city.

The Hanoi Department of Construction has once again requested the team to show their legal documents, but so far the company has not responded to the request.

Many canals in HCM City are struggling with the serious pollution due to illegal waste dumping.
