In China, achieving rural drinking water safety—meaning access to a safe, affordable, sufficient, and sustainable drinking water supply—remains a key challenge for government agencies and researchers. Using cross-sectional data at the provincial level, in this paper we examine the impacts of socioeconomic development on drinking water safety in rural China. Using a theoretical framework called Pressure-State-Response (PSR), existing data were organized into state and pressure indicators. Canonical Correlation Analysis was then used to analyze provincial-level relationships between the indicators. Significant drinking-water-safety-related differences were found across provinces. Our analyses suggest that, overall, China’s recent and rapid socioeconomic development yielded substantial benefits for China’s rural drinking water safety. However, this same development also negatively impacted rural drinking water safety via increased groundwater over-abstraction, reductions in water supply, and environmental contamination. The paper closes with a discussion of implications and options for improving drinking water policy, management, and regulation in rural China.

Water Safety Plan

The Water Safety Plan (WSP) concept has become a globally recognised and accepted approach to drinking water supply management and operation. Many countries around the world are adopting this proactive, risk-based model for ensuring consistent confidence in drinking water safety, accessibility and affordability. While it is widely accepted that the WSP concept is an appropriate tool for ensuring drinking-water supply efficiency, the process for gathering the required evidence to demonstrate this continues to be rather vague. The problem may lie fundamentally in the way WSPs are developed and implemented. This paper discusses the need for establishing performance targets, identifying key performance indicators and monitoring these to build a body of evidence that would be instrumental in demonstrating whether WSPs are effective or not.

Abstract A descriptive cross-sectional study employing a structured questionnaire was employed to assess knowledge, attitude, practice, and satisfaction (KAPS) of Gaza's community on issues related to household drinking water safety. The results showed that of 1,857 household heads, 1,621 (87.3%) were males, with the majority (967, 52.1%) having a university educational level. Of surveyed households, 744 (40.1%) consisted of 5–7 persons and 885 (47.7%) of the households resided in refugee camps. Mean percentages for KAPS were 82 ± 15.5%, 64.9 ± 39.7%, 53.2 ± 14.1%, and 37.3 ± 26.56%, respectively. There were statistically significant associations between some sociodemographic variables and mean percentage of KAPS scores. Educational level was the only variable significantly associated (p < 0.05) with all mean KAPS scores. There was a significant positive linear correlation between knowledge-attitude (r = 0.362, p < 0.05), but a significant negative linear correlation between knowledge-practice (r = −0.070, p < 0.05) was also observed. Therefore, the Local Government Authority (LGA) should arrange community awareness campaigns on the importance of safety and hygiene measures of drinking water storage. Furthermore, and due to the poor financial capabilities of the LGA in Gaza, it is highly recommended that LGA contact relevant international donors in order to support programs aiming at improving household water supply.

Drinking Water Safety

Management of drinking water safety is changing towards an integrated risk assessment and risk management approach that includes all processes in a water supply system from catchment to consumers. However, given the large number of water supply systems in China and the cost of implementing such a risk assessment procedure, there is a necessity to first conduct a strategic screening analysis at a national level. An integrated methodology of risk assessment and screening analysis is thus proposed to evaluate drinking water safety of a conventional water supply system. The violation probability, indicating drinking water safety, is estimated at different locations of a water supply system in terms of permanganate index, ammonia nitrogen, turbidity, residual chlorine and trihalomethanes. Critical parameters with respect to drinking water safety are then identified, based on which an index system is developed to prioritize conventional water supply systems in implementing a detailed risk assessment procedure. The evaluation results are represented as graphic check matrices for the concerned hazards in drinking water, from which the vulnerability of a conventional water supply system is characterized.

In recent years, China has paid an increasing amount of attention to improving urban and rural drinking water safety, an important aspect of building a healthy and stable society. This study analyzed countermeasures to promote drinking water safety in Turpan City of Shanshan County, in the Xinjiang Autonomous Region. First, we considered the current state of drinking water safety in Shanshan, including issues such as pollution, outdated water treatment technologies, leakage in the water supply pipe network, insufficient emergency management capability in urban areas, and low water supply guarantee rates in rural areas due to poor construction standards. Second, the quantity of guaranteed water resources was estimated; on this basis, an ideal distribution of regional water plants and water supply network needs for the optimal allocation of water resources is suggested. Third, a water purification program was developed to solve untreated water quality problems, including centralized and decentralized water quality treatments alongside intelligent water flow control processes. Water resource conservation and risk control measures are also proposed in order to promote the security of drinking water; equipment updates, and the establishment of an intelligent water management platform are also suggested.

Disinfection is a very significant water treatment process for drinking water safety, as it inactivates pathogens from drinking water. However, disinfection-by-products (DBPs) are formed which are accused of contributing to cancer and reproductive/developmental effects. Research has provided many predictive models for the formation of DBPs based on various water quality parameters and following different methodologies. The present study aims at developing predictive models for the formation of DBPs in two drinking water supply systems in Greece. Data from the water supply systems are used. A statistical analysis took place to identify the predictive models for the formation of Total trihalomethanes (TTHMs). The results showed that some of the developed models are more reliable than others. However, further study is necessary in order to obtain more data on variables that are affecting trihalomethanes (THMs) formation. Such models can be used mainly locally.

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.
