Cancer village is the word used in Vietnamese to refer to villages in Vietnam, where many people have cancer because of water pollution. According to the Ministry of Health, as of 2007, there are about 51 villages and communes scattered in 25 provinces/cities nationwide recorded as “cancer villages”. Focusing mainly in the North and Central – where high-intensity handicraft and craft village activities take place (Ha Tay, Bac Ninh, Nam Dinh), near old industrial zones (such as Thai Nguyen, Phu Tho) or near old plant protection warehouses (Nghe An, Ha Tinh) … 
Water sources in cancer villages in Vietnam according to the investigation are polluted by pesticides at drug stores, war poisons, graveyards, craft villages, domestic and industrial wastes, and public works. The analysis results of water samples being used for drinking in the “cancer villages” show that most of them are contaminated with microorganisms, some samples have Content of phenol, arsenic or manganese exceeds the permissible standard many times.

Case Thach Son Cancer village: The village is contaminated, in both air and water. According to a survey by the Ministry of Natural Resources, the atmosphere here is seriously poisoned by industrial emissions, especially in the area around Lam Thao Supe phosphate factories, Phu Tho battery factory. Besides, the breathing air in Thach Son must receive smoke from 90 brick kilns and the bad smell at the outlet of the wastewater of the Bai Bang paper factory to the Red River. Regarding water sources, both surface water and groundwater in Thach Son are toxic. All lakes and wells are polluted. 
From 1991 to 2009, Thach Son commune had 106 people died of cancer, most commonly cancer of the liver, lung, stomach, throat. 19 families with at least 2 people die from this disease (husband and wife, or father and daughter, mother and child), of which more than 3 people have died from cancer. In the Mom Den area, 15 years ago, 200 households had moved to another place by themselves because they could not stand the heavily polluted air from the Lam Thao Supe Phosphate factory. 70% of these families have died of cancer. 
I would like to propose three levels of responsibility: Change starts from a systemic level to corporate responsibility and consumerism. The government has the power to gives permission for fabrications’ manufacturing activities on their homeland, hence, takes major responsibility for environmental and social impacts. Corporations must make ethical decisions that impact both the environment and humans. Consumers contribute to the scene by being mindful of everyday consumption, raising environmental concerns, and pushing for systemic changes.
Three levels of responsibility
