Abstract: | In this study, we focused on water quality in an urban canal and the Mekong River in the city of Can Tho, a central municipality of the Mekong Delta region, southern Vietnam. Water temperature, pH, electrical con- ductivity, BOD₅, CODCᵣ, Na⁺ , C1ˉ, NH₄⁺-N, SO₄²ˉ -S, NO₃ˉ-N, and NO₂ˉ-N for both canal and river, and tide level of the urban canal, were monitored once per month from May 2010 to April 2012. The urban canal is subject to severe anthropogenic contamination, owing to poor sewage treatment. In general, water quality in the canal exhibited strong tidal variation, poorer at lower tides and better at higher tides. Some anomalies were observed, with degraded water quality under some high-tide con- ditions. These were associated with flow from the up- stream residential area. Therefore, it was concluded that water quality in the urban canal changed with a balance between dilution effects and extent of contaminant sup- ply, both driven by tidal fluctuations in the Mekong River. |
