The main objectives of this project were: (1) to propose the CCLs of the “Surface Water Classification and Water Quality Standards”; (2) to establish the human health effect database of the CCLs’ items; (3) to review the classification of the surface water and the corresponding standards; and (4) to evaluate the contribution of the constructed wetland on eco- and environmental aspects. Through comparing with foreign countries’ standards, this project reviewed the recent “Environmental Standards for Protecting Human Health” in the “Surface Water Classification and Water Quality Standards”. Samples taken from the representative reservoirs and surface waterbodies were analyzed to check the environmental background information for the suggested new items and their relative standards. With the above efforts the contaminant candidate lists (CCLs) for protecting human health then proposed as well as their corresponding human health effect database.This project reviewed the standards of ammonia, total phosphate, suspended solid in the“Surface Water Classification and Water Quality Standards”, as well as the total coliform standard for the river and marine waterbodies. In addition, this project also reviewed the index for evaluating the extent of eutrophication for reservoirs, Carlson trophic state index(CTSI),and of the pollution for rivers, river pollution index (RPI), and proposed recommendations forfurther revision. Finally, this project designated a constructed wetland to evaluate theperformance of improving water quality, the promotion of biodiversity, and the contribution tothe environment.
