The objectives of this research were to evaluate the trophic state using input-output models for some Korean lakes such as Daechung, Juam, Paldang and so on. Input-output models were designed to predict the trophic state of a lake and could be useful for water quality management in lakes. In this study, the applied empirical models were Vollenweider model, Larsen and Mercier model and Dillon model The results were as follows : 1. Total phosphorus to total nitrogen ratios in lakes were very high. It was estimated that lake productivity was influenced in accordance with the increase of phosphorus level. 2. A low correlation was found between the predicted total phosphorus concentration and chlorophyll-a concentrations. 3. The Present trophic states of the observed lakes might be evaluated to be eutrophic by the input-output models. In this respect a further study on the phosphorus removal of lake was needed.

Although it produces well-treated water in water treatment plant, water quality at the tap can be changed depending on the state of pipes. It is because water quality deteriorates as plant water passes through pipeline networks. Therefore, the improvement of not only water treatment technology but also O & M of water pipelines is required to supply good water to consumers. The purpose of the study was to obtain the basic data of control technology for water quality in pipes through investigating water quality in distribution system. We selected 11 sampling sites and investigated water quality from plant to endpoint of distribution system. We also simulated decreasing tendency of free chlorine through pipeline network. As the result of water quality test, all parameters were below allowable levels, but some parameters had the possibility of being over levels. So there must be more work to set up proper countermeasure for violable paramenters.
