Goals of this project were (1) to collect the information about the distribution of industries and pollution amounts discharged by industries around the Ke-ya River; (2) to investigate the pollution condition of Ke-ya River and to analysis the hot spot of pollution and the relationship between pollution sources via statistics. In order to achieve these two goals. The framework of this project was divided in two parts. The first one is to collect information about literatures of environmental forensics technologies and pollution background of Ke-ya River’s water and sediment. In this project, analyzing profiles of characteristic heavy metals by ICP-MS and identifying the sources of heavy metals by Pb, Zn and Cu’s isotopes via MCICP-MS were the major targets for the literature collection. For Ke-ya River background, flow direction, water flow, treatment and management conditions, distribution of industries and pollution amounts discharged by industries and historical pollution data were gathered. The second one is to trace and identify different pollution sources, and to analyze the relationship between hot spots and contamination sources via EPA-CMB8.2 statistic method. Suitable sampling locations were planned to take typical water and sediment samples. Collected samples included effluents from industries and pollution sources, river water and sediments in Ke-ya River. Those samples were analyzed for getting the pH values, conductivity, COD, BOD, NH3-N, heavy metals and organic compounds (volatile, semi-volatile and water-soluble compounds). After the data interpretation, this project had successfully found out the characteristic indicators for the pollution sources of Ke-ya River, such as F-, Br-, PO43-, NH4+, As, Ce, Cu, Ga, Ge, Hg, Ni, Sn, Ti, W, Silane, fluorotrimethyl-and Silanol, trimethyl-. Additionally, the contributions of different pollution sources (effluents from science park, domestic sewage, paper mill and glass factory) were figured out.
