The emerging pollutants presence in the water is an environmental problem. In addition to this, their presence involves a drinking water quality problem of concern in developing and developed countries around the world because of its impact on the population health. Nowadays, thanks to improvements in the analytical sensitivity methods for the measurement of these chemicals at very low concentrations we can control water quality with the aim to treat it in water purification plants for reduce health risks. The contamination concentration increase in water supposes a human health risk and the traditional management and treatment could not be useful to resolve this current problem. The experience shows the value of preventive management approaches that range from water resources to the consumer.The most effective way to ensure the drinking water supply system safety is to apply a comprehensive approach to risk assessment and risk management covering all stages of the supply system, from the catchment basin to its consumer distribution. Water Safety Plans are an integral water supply management focus on identifying pollutants, their risks and can indicate how to eliminate them. The Water Safety Plan main objectives are: ensure the safety of drinking water supplied, reducing the health risks and guarantee a quality water distribution system.This elimination is done in the water purification plants obtaining the health risk reduction and an environmental benefit. The paper's objective is to show the environmental role of the water purification plant

Beijing-Tianjin-Hebei region is the most developed region in North China, but it has been facing great water shortage. This paper builds a decoupling model, with the aim of investigating the decoupling relationship between economic development and water resources use in this region. The decoupling relationship between water resources use efficiency with regional economic development and with regional industrial development in 2001-2015 in Beijing, Tianjin and Hebei has been evaluated. Results show that the three provincial administration areas have different decoupling status. Beijing shows a strong decoupling trend between water resources use efficiency and economic development. Tianjin shows a two-stage decoupling where it was weak decoupling from 2001 to 2007 and a strong decoupling after 2007. Hebei shows a fluctuant trend, where some of the selected years are weak decoupling and the other years show strong decoupling relationships. The decoupling mechanism has been analyzed to explore reasons of the different results. Then, regional water demand from 2016 to 2030 is predicted with Logistic model and the demand results are then modified taking consideration of regional development planning. Policy suggestions are made based on the evaluation and the prediction analysis for the regional and industrial development, as well as water resources management, to help enhance regional sustainable development.

The Republic of Korea experienced rapid industrialization and urbanization in the 1970s and 1980s, which was incomparable to developed countries. Since the end of the 1990s, the decline of old downtown has occurred due to the counter-urbanization of existing old downtown and the development projects of surrounding areas. To solve these problems, Korea enacted and enforced the "Special Act on the Promotion and Support of Urban Regeneration." Currently, the Urban Regeneration has been promoted through various bodies of central government, local governments, private operators and local residents. In the case of receiving the support of the government among the types of Urban Regeneration, which is currently being promoted, both the physical and environmental improvement and the reinforcement project of regional capacity have been promoted together through the community participation. These projects go through a series of process, which is different from other drawing processes of consensus and convergence of existing development projects. However, there is a limit for local residents to understand urban regeneration systematically. In addition, although the Korea Urban Renaissance Center (KURC), which was established in 2007, has been carrying out various studies, in association with urban regeneration, the information of Urban Regeneration, which makes local residents understand easily and arrange in a sustainable way, is insufficient. Therefore, the purpose of this study is to elucidate the essential factors for the sustainable urban regeneration and to evaluate the sequence of the important level and the implementation level based on the derived factors, so as to complement factors, which are likely to be overlooked in promoting urban regeneration.
First, it drew the direction and domain of the comprehensive form by conducting meta-analysis around literature and cases, and then it analyzed the factors of urban regeneration to which the Focus group interview method (FGI) with the experts of urban regeneration is applied. Lastly, it analyzed the importance and satisfaction of the sectoral factors by using Importance-Performance Analysis(IPA). Based on the study results, it analyzed the priority areas for the sustainable urban regeneration. It is judged that this study will contribute to the policy decision-making in the region where urban regeneration will be promoted in the future.

Water shortage and water pollution are important factors restricting sustainable social and economic development. As a typical coal resource-exhausted city and a node city of the South-to-North Water Transfer East Route Project in China, Zaozhuang City’s water resources management faces multiple constraints such as transformation of economic development, restriction of groundwater exploitation, and improvement of water environment. In this paper, we develop a linear optimization model by input–output analysis to study water resources management with the introduction of three advanced sewage treatment technologies for pollutant treatment and reclaimed water production. The simulation results showed that from 2014 to 2020, Zaozhuang City will realize an annual GDP growth rate of 7.1% with an annual chemical oxygen demand (COD) emissions reduction rate of 5.5%. The proportion of primary industry, secondary industry, and tertiary industry would be adjusted to 5.6%, 40.8%, and 53.6%, respectively. The amount of reclaimed water supply could be increased by 91% and groundwater supply could be decreased by 6%. Based on the simulation, this model proposes a scientific reference on water resources management policies, including water environment control, water supply plan, and financial subsidy, to realize the sustainable development of economy and water resources usage.
