The purpose of this project is to assist the Environmental Protection Administration, Executive Yuan (EPA) to achieve it’s yearly goal of implementation of contaminated sediment management strategy. In total, 242 submitted sediment sampling plans and 135 reports of sediment quality survey were reviewed and revised. Results of sediment quality survey in the first run (2014-2019) conducted by corresponding administration of water bodies were also collected and analyzed in this project. Among those results, concentrations of contaminants, mainly heavy metals, in 78 water bodies exceed the upper limit of Taiwan sediment quality indicators, which are required to initiate further risk assessments thereafter.
Also, a framework of contaminated sediment management strategy and classification inventory were established based on the role and characteristics of water body and their pollution potential. Meanwhile, 11 water bodies which exceeded the upper limit of Taiwan sediment quality indicators were selected to be further investigated for confirmation. According to those confirmation results, classification procedures of sediment mixing with background substances are also established. In order to better manage sediment, the detailed data of sediment quality and aquatic environmental parameters need to be compiled as a database which was also organized and depicted preliminarily in this study. A list of domestic or foreign concerned emerging chemical pollutants in sediment was reviewed and 400 chemical substances were chosen as candidates to be assessed to add into Taiwan sediment quality indicators by their characteristics including persistence, bioaccumulation and aquatic toxicity. To propagandize the concept of protecting sediment quality in the water bodies, a children’s picture book ‘‘The Adventure of Nippo Moving to its New Home’’ was also completed in this project.
