The figures showed:• Water quality in HO CHI MINH CITY. HCM declined mainly due to the discharge of waste water from industrial production and waste water sources (point sampling from NM1 to NM9);• Water quality is particularly bad in the outlet of the THLG Canal when the tide down. This is due to the fact that there is no dilution of the THLG canal water.• The quality of river water Buffer Market are going bad from fork THLG Canal due to the discharge of wastewater not treated;• The water quality of the river relatively Cushion Market not good for is the confluence with the rivers, affected by poor quality water from the Saigon River at the Imperial Court.on the issue of the nutrients (TN and TP), the concentration found in surface water no higher (about 1 mg/L 0.3 mg/L TP and TN); Therefore the specific processing for nitrogen and phosphorus in NMXLNT has not been considered a priority area in the development stage of drainage system in Ho Chi Minh City. QCVN standard 14-2008 can therefore be applied to NMXLNT Many Loc Poor Marketing.
