[Objective] To learn the sanitary condition of drinking water in rural areas of Nantong and provide scientific basis for improving water quality and reducing water borne diseases. [Methods] Survey was carried out on water sources and water sterilization. Water quality was randomly detected and water borne diseases were also investigated. [Results] 75.80% of the rural population drank underground water. The leaking problem of the pipes was serious, the earth surface was contaminated, and most of the well water was not sterilized. Because of all of the above existing problems, the total number of bacteria, coli groups, ammonia, nitrogen, nitrite and oxygen consumption all exceeded the maximum volume of the sanitary standard. [Conclusion] The water contamination in Nantong rural areas is serious; it is strongly suggested that emphasis should be put on improving water quality and reducing water borne diseases.
