Abstract:
In this paper, the multi-index comprehensive evaluation method was used to evaluate the water quality of Erhe drinking water source region of Huaian city in 2012, and the results showed that the current water quality meets the standards of drinking water. The risk scales of water pollutants on public health were assessed using the Water Environmental Health Risk Assessment Model of U.S.EPA, which indicated that the personal annual risk caused by the chemical carcinogens through drinking water is much greater than that by the non-carcinogenic substances, and the order of risk scales for all pollutants is As>Pb >Fluoride>Nitrate>Mn >Fe>NH3-N. The research results can provide technical support for the water quality management of Erhe drinking water source region.
