Water pollution is a serious issue in Vietnam as a result of rapid industrialization and urbanization without adequate environmental management. As of 2008 only 10 percent of municipal wastewater was treated, and only 45% of industrial zones were expected to have wastewater treatment of some kind in 2010. [ 3 ]
Caused by drinking water contaminated by bacterium, the number of reported cholera is well above 500, reaching 1900 in 2007, and 600 in 2010. [34] However, the fatality rate of cholera has been close to 0% since 1999. [34] Wetlands: Wetlands in Vietnam, along with their biodiversity, have decreased significantly.
In chemistry, polarity is a separation of electric charge leading to a molecule or its chemical groups having an electric dipole moment, with a negatively charged end and a positively charged end. Polar molecules must contain one or more polar bonds due to a difference in electronegativity between the bonded atoms.
Arsenic contamination of groundwater is a form of groundwater pollution which is often due to naturally occurring high concentrations of arsenic in deeper levels of groundwater. It is a high-profile problem due to the use of deep tube wells for water supply in the Ganges Delta, causing serious arsenic poisoning to large numbers of people. A ...

The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
The 2016 Vietnam marine life disaster was a water pollution crisis affecting Hà Tĩnh, Quảng Bình, Quảng Trị and Thừa Thiên–Huế provinces in central Vietnam. Fish carcasses were reported to have washed up on the beaches of Hà Tĩnh province from at least 6 April 2016. [ 1 ]
The forests of Vietnam especially were very vulnerable to a chemical such as Agent Orange, and by the end of the 9 year campaign, 11 million gallons of Agent Orange had been dropped on the region including Laos, Cambodia, and mostly Vietnam. These herbicides not only affected the landscape of Vietnam, but had disastrous effects on the human body.
