In some remote areas in Vietnam, some people do not have enough clean water to use. As a result, they have to use the water from the river or hand-digged wells and they contain some substance that affects health. Moreover, water filtration systems are impossible to meet the needs of people. The authority has applied a lot of solutions and actions but it must take a lot of time and efforts to supply clean water to every house. Furthermore, the rivers and lakes are contaminated by factories that pour waste into them. They should have inadequate waste-treatment systems to filter the waste before pouring it into the river and the government should have new strict laws to prevent the firm pour waste into water. Water pollution causes great damage, it causes diseases like cholera, diarrhea and skin diseases. The fatality rate of cholera has risen recently especially the children under 5. Water pollution can destroy farming and kill animals around the source like fish and some aquatic life. Water pollution can kill plant life, plants died when they were irrigated with water containing heavy chemicals.
