A canal at Alley 196 in Dai Mo Ward, Nam Tu Liem District has become a landfill for many years.
Rubbish is dumped into the canal, causing a foul odour.
A 100-metre canal which is situated on Tran Cung Street in Cau Giay District is full of rubbish.
Scraps are also dumped along the canals. The pollution poses health risks for people who live near the canal.
Hanoi has 104 irrigation lakes, 105 rivers and canals with a total length of more than 799km, the municipal Department of Natural Resources and Environment reported. However, water sources are in danger of depletion and pollution.
