As more and more non-public fund entering rural drinking water safety engineering project market; it becomes very necessary to built rural drinking water safety engineering project guarantee mechanism. This paper proposes three steps of mechanism design. Firstly, history data is used to fit multivariate linear equation set up describing relationship between bank loss and key risk factors. Secondly, guarantee fee is calculated through model regression, which is threefold of possible bank loss. Thirdly, guarantee fee is adjusted according to variety of key risk factor in the process of project construction and operating.

If consumers detect an off-flavor in their drinking water, they are likely to believe that it probably is not safe. Water utilities will be defeating their best efforts to provide safe drinking water if they only meet health-related regulations and do not provide water that is free of off-flavor problems. The purpose of this paper is to explore the current U.S. regulatory environment and discuss how these regulations can adversely impact the control of off-flavors in drinking water. Utilities should adopt a water quality goal that allows them to not only meet the minimums of the regulations, but also meet the customer's highest standards - water that is free of off-flavors.

This paper explores the physical, social, and environmental dimensions of how climate change impacts affect drinking water safety in a rural context in developing countries. Climate impacts, such as contamination or the reduced availability of preferred drinking water sources due to climate-related hazards, threaten water safety in rural areas and these impacts will likely worsen as climate change accelerates. We qualitatively examined these impacts in a community in rural Vanuatu using three approaches side-by-side: adaptation, vulnerability, and resilience. We employed a mixed methods case study methodology that combined semi-structured interviews, technological and environmental surveys, and observations. We demonstrate the influence of physical infrastructure design, social structures mediating water access, and the availability of multiple sustainable water resources on water safety with respect to climate impacts. We also show how the initial problematization of how climate affects water safety can influence subsequent actions to address, or overlook, issues of infrastructure design and maintenance, social equity, and natural resource management for water access. Improvements to rural drinking water safety management in the context of climate change should take a pluralistic approach, informed by different conceptualizations of climate impacts, to account for the varied causal pathways of reduced water safety for different members of a community.

Key Issues

Drinking water supplies continue to be a major source of human disease and death globally because many of them remain unsafe and vulnerable. Greater efforts are needed to address the key issues and questions which influence the provision of safe drinking water. Efforts are needed to re-evaluate and set new and better priorities for drinking water research and practice. More stakeholders need to be included in the processes of identifying key issues and setting priorities for safe drinking water. The overall approach to drinking water research and the provision of safe drinking water needs to become more rational and scientific, and become more visionary and anticipatory of the ever-present and emerging risks to drinking water safety. Collectively, we need to do a better job of making safe water available, accessible and affordable for all. One such approach to safe water for all is household water treatment and safe storage, which is being promoted globally by the World Health Organization and many other stakeholders and partners to reduce the global burden of waterborne disease.

Drinking Water Safety

In the process of solving rural drinking water safety,there are some problems need to attach great importance. Evaluation index system of rural drinking water safety includes water quality, quantity, convenience, and dependability. Figure 1 shows that Polluted water is the main reason of unsafe drinking water quality, 40.9% of unsafe drinking water quality, 28.8% of unsafe drinking water. Figure 2 shows that basically the discharge of waste water each year from 1998 to 2009 is increasing, the total discharge of waste water across China from 1997 to 2009 reached to 621.945 billion t. Table 2 shows that national industrial solid waste generation and utilization is increasing,but discharge decreasing, industrial solid waste, directly or indirectly polluted water environment, especially rural drinking water sources. The paper draws a conclusion that there are some problems of rural drinking water such as rural unsafe drinking water quality, lack of laws and regulations and effective management, serious rural water pollution.

The paper analyzes the water supply in the rural part of Zagreb County, which is based mainly on individual water supply sources, i.e. dug or drilled wells and Norton pumps.The aim of the paper is to investigate whether there is a difference in health quality of drinking water taken from the wells and taken from the Norton pumps. The wells are supplied from an aquifer that lies at a depth of 12 to 14 meters, while the Norton pumps reach a depth of 6 and 7 meters.The analysis of water samples taken from the water supply sources revealed that the water does not basically comply with the Ordinance on the parameters of assessment and the methods for the analysis of water intended for human consumption, the Act on Water Intended for Human Consumption. Organoleptic indicators such as color and clarity do not satisfy, while the physical and chemical parameters such as pH and conductivity satisfy the criteria set for both water supply sources. Of all the chemical parameters only the chloride content was within the permitted limits, while the oxidativity, the content of ammonium, nitrite and nitrate were above the allowed limits in water samples taken from the wells and Norton pumps. Microbiological indicators in the analyzed samples, i.e. the number of colonies at 37 ° C and 22 ° C, as well as total coliforms also do not satisfy the requirements of the Ordinance. In order to use the water for drinking it is necessary to perform the conditioning and disinfection of wells, while with the Norton pumps these interventions are almost impossible to perform.

Safety Of Drinking Water

Traditionally, the regulatory approach to maintaining the quality and safety of drinking water has largely been a prescriptive one based on the ability of any given supply to meet standards set for a number of different chemical and biological parameters. There are a number of issues around the assumptions and the limitations of a sampling and analysis regime. The basis for such regimes is essentially reactive rather than proactive and, consequently, the cause of the concern may already have impacted consumers before any effective action can be taken. Environment and Sustainable Resource Development has developed a template for recording drinking water safety plans together with guidance notes to help complete them. The template has been developed in MS-Excel and has been designed in a straightforward step-wise manner with guidance on the completion of each sheet. It includes four main risk tables covering each main element of water supply which are pre-populated with commonly found ‘generic’ risks and these are carefully assessed before considering what action is required to deal with significant risks. Following completion of the risk tables, key risks are identified and the interventions required to bring them into control.
