In 2004, a survey on pathogenic microorganisms in contaminated river in HCMC was conducted. As a result, the concentration of coliform group and viruses in contaminated rivers in HCMC was found to be the same level as sewerage in Japan. In 2005, a survey was conducted in January and February, on the health impact of flooding in the communities along the Chiliwung River, and the following conclusions were obtained:1)The major source of drinking water in the flooded are is shallow groundwater, which was contaminated with flood water.2)The flood water that went into houses stay long hours, and the levels of coliform group were higher than Chiliwung River.3)In the flooded area, the cases of diarrhea, skin diseases and influenza, were much higher than in the non-flooded area.As a results of this survey, it was concluded that, in addition to the direct damage such as drowning, flood events force the local residents a long evacuation lives, and bring about health impacts.In 2005, a similar flood survey as Jakarta was conducted in HCMC. In 2006, water quality monitoring was conducted along Sai Gon River and canals that flow into Sai Gon River. There is no tidal gate in Sai Gon River; hence the water level fluctuates a lot due to tidal fluctuation. There is no central wastewater treatment plant in HCMC, and both domestic and industrial wastewaters go Sai Gon River only after simple treatment like sedimentation. Hence it was found that the contaminated water from HCMC goes up the point of the city's water intake. If the water level goes up due to Global Environmental Changes, Asian coastal mega-cities such as Jakarta and HCMC will suffer more severely from flood events, and the cases of health effect will go up.

2004年，对HCMC污染的河流中的致病微生物进行了一项调查。结果，发现HCMC中污染河流中大肠菌群和病毒的浓度与日本的下水道的水平相同。 2005年，一月和二月进行了一项调查，该调查涉及北河河沿岸社区的洪水影响，并得出了以下结论：1）1）洪水中的饮用水的主要饮用水来源是被洪水污染的浅层地下水，被洪水泛滥。腹泻，皮肤疾病和流感，比在非洪水区域中高得多。作为这项调查的结果，得出结论，除了直接损害外，诸如溺水之类的直接损害（例如溺水外，洪水事件）迫使当地居民长期撤离生活，并带来健康影响，并带来2005年的健康影响。在2005年，与Jakarta类似的洪水调查与HCMC进行了类似的洪水调查。 2006年，沿Sai Gon River和流入Sai Gon River的运河进行了水质监测。赛登河没有潮汐大门。因此，由于潮汐波动，水位波动很大。 HCMC中没有中央废水处理厂，只有在简单的处理（例如沉积）之后，家庭和工业废水都会去Sai Gon River。因此，发现来自HCMC的受污染的水升至城市的饮水量。如果由于全球环境变化，水位升高，雅加达和HCMC等亚洲沿海巨型城市将因洪水事件而受到更严重的损失，而健康效应的案件将增加。
