As the economy has been growing fast in China, Chinese people have more incomes and then higher standard of living. In the case of household water treatment, more and more urban residents in China use bottled water or water filtration system instead of tap water because people start to worry about polluted tap water. According to a survey from China Water Supply Services Promotion Alliance in 2014, 59% of urban residents drinking water is from tap water (after being boiled), 41% from bottled water and water filtration system. The 41% participants prefer bottled water as the first choice over a water filtration system. The comparative advantages and disadvantages of home water filtration system and bottled water are analyzed using comparative analysis. The reasons why home water filtration industry has grown slowly in urban China even though it is less expensive and has environmental benefits are analyzed using a system dynamics model. The model focuses on the physical system of home water filtration industry. The study shows that order delivery delay and service time are key factors to the adoption rate of home water filtration system. However, initial cost becomes a limiting factor to the growth of the market of home water filtration system. The study proposes the according market policy, demand policy, and supply policy to improve the current scenario.

The one- to four-page fact sheets will be assembled into a two-pocket folder entitled Private Well Owners Guide. The titles will also be a part of the Changing Rural Landscapes project whose goal is to educate exurban, small acreage residents. The authors have made every effort to align the fact sheets with the proposed Arizona Cooperative Extension booklet An Arizona Well Owners Guide to Water Sources, Quality, Testing, Treatment, and Well Maintenance by Artiola and Uhlman. The private well owner project was funded by both the University of Arizonas Water Sustainability Program-Technology and Research Initiative Fund and the USDA-CSREES Region 9 Water Quality Program.

This research examines the application of a Classic Glaserian Grounded Theory methodology to the phenomenon of drought when viewed from the perspective of household water users in southern England. The resulting conceptual work calls into question the effectiveness of water-wise messaging and current Government policies on water management, by highlighting the double assurances afforded to the public through their own observations of the natural cycling of water resources between atmosphere and land, and the continuous operation of the regulated water industry, that together sustain blind belief in the ongoing availability of potable water resources. To establish a clear separation between the development of substantive theory and mixed method studies that claim to take a grounded theory approach that are generally more popular within the discipline of Human Geography, the theory is presented alongside two pieces of work; a collection of modern drought histories and a questionnaire. Developed as part of the necessary process of cycling alternate projects to enable a theory to emerge from the data whilst the researcher is distracted from forcing her own ideas onto it, both these pieces can be viewed separately or as supportive companions to the theory. Additionally, in acknowledging the difficulty in presenting a Classic Grounded Theory in the traditional discussional form, for the benefit of the reader the theory is preceded by an autoethnography, which incorporates descriptive elements taken from field notes and the author’s personal water diary. These works draw data from subjects in three counties in England (Norfolk, Kent, and Devon), following the northwest – southeast rainfall gradient. Supplementary material for the drought histories is drawn from local and national archives and recorded oral histories. The primary emphasis of this work is placed on assessing the merits of each of the methods deployed in addressing environmental social science issues in the context of climate change, which hitherto have been focused on perception questionnaires and the development of popular cultural typologies.
