Abstract：The source of accidental water pollution can be accurately and quickly identified using a water environment model and database. The Foshan section of the Xijiang and Beijiang Rivers was taken as an example to build a EFDC (environmental fluid dynamics code) hydrodynamic and WASP (water quality analysis simulation program) water quality model. The WASP water quality model included the WASP-EUTRO model for normal pollutants and the WASP-TOXI model for toxic pollutants. The EFDC-WASP model sorts information on the pollutant risk source at each automatic monitoring section to establish a toxic and normal pollutant source identification database. A hypothetical scenario having the Shakou monitoring station in the Chancheng district measuringa high Cr6+ concentration was taken as an example with 3 possible pollutant emission situations identified through a database query. Initial loads for each situation 1-3 were estimated according to a first-order kinetics equation, with the location and load for each situation then calculated by the model. The pollutant source was quickly and accurately identified.
