Evaluation of eutrophication indicators for reservoirs in TaiwanTsay, Fwu-shoei 13 August 2007 (has links)
Reservoirs are the main drinking water sources in Taiwan. However, about half of 23 reservoirs suffer the eutrophication problems based on the calculated Carlson¡¦s TSI indexes for them. Thus, the reservoir water is seriously polluted. Chen-Ching Lake Reservoir, Fengshan Reservoir, and A-Kong-Tien Reservoir are three major reservoirs that supply water for the domestic, industrial, and agricultural uses in the Kaohsiung area. Due to the long-term sediment deposition at A-Kong-Tien Reservoir, a sediment dredge system is under construction at this reservoir. Thus, only Chen-Ching Lake Reservoir and Fengshan Reservoir play the most important roles in water supply at this moment. However, both Chen-Ching Lake Reservoir and Fengshan Reservoir are in the list of the most eutrophized reservoirs. There are several ways to evaluate the status of eutrophication of reservoirs. The single-index method and multi-variable modeling method are two of the most commonly methods for water quality analysis and eutrophication evaluation for the reservoirs in Taiwan. Based on the analytical results from previous studies, eutrophication results in the fast growing of seaweeds and they spread and cover the whole water bodies, which is called algal bloom. The type of seaweed causing eutrophication in Taiwan reservoirs are mainly Cyanobacteria, especially the commonly found Microcystis. They can not only cause some foul smells but release toxins into the water bodies. That endangers the safety of drinking water and affects the normal water usage. To prevent eutrophication, the nutrients loadings outside and inside of the reservoir areas must be reduced and controlled, which can effectively prohibit the growth of seaweeds. An air-pumping system can also be built for the same purpose. Regular water quality inspection should be carried out to monitor the fluctuation of water quality.
