Most of China's water resources in rural areas naturally contain excessive levels of heavy metals, such as arsenic, fluoride and iron, as well as some radioactive elements, according to the report.
Rural water pollution, the result of rising incidents of industrial pollution, outdated sewage systems, and the overuse of pesticides and chemical fertilizers, also endangers the health of rural inhabitants in China, it said.
Industrial pollution is responsible for depositing heavy metals and nitrates in rural water supplies, contributing to eutrophication, a process in which excessive nutrients stimulate abundant plant growth that depletes the oxygen supply for other aquatic life.
"It is a challenge for us to be able to guarantee the safety of rural drinking water, especially when industrial pollution is moving from cities to the countryside and we lack a comprehensive rural sewage treatment system," said Ni Wenjin, deputy director of the department of rural water resources under the ministry and a co-author of the report.
