Every year 2800 deaths in Pacific island countries result from diarrhoea, and most are children under five years of age. These tragic diarrheal deaths are preventable as they are often linked to unsafe water, lack of proper sanitation facilities and poor hygienic practices. Effective preventive management through the framework of a drinking Water Safety Plan (WSP) is an efficient mechanism for ensuring the safe quality of drinking water thereby reducing the burden of water related diseases. The large proportion (81%) of people in Pacific island countries living in rural or outer island communities mostly have their own water supply (for example rainwater tanks or hand-dug wells), and often the water is consumed untreated. The remoteness and isolation of these rural communities prevent national surveillance authorities to regularly visit and provide advice on drinking water safety issues. In such circumstances empowering rural communities to ensure the safety of their drinking water, through trained local facilitators, could be promoted and utilised effectively. However, WSPs for rural communities have to be relatively simple hence tools such as modified sanitary inspections and the presence/absence hydrogen sulfide test could be used. The approach of empowering communities through trained local facilitators to promote the WSP framework has been implemented in the Republic of Marshall Islands (RMI). Positive feedback has been received by trained facilitators in RMI on the use of modified sanitary inspections (translated into Marshallese) and the hydrogen sulfide test. It is believed that the approach of empowering communities on WSPs through training local facilitators and equipping them with the above mentioned simple tools is effective and has potential for further replication in rural Pacific communities to improve drinking water quality and reduce the burden of water related diseases.

Introduction. The safety of drinking water should be considered in the context of managing the risk from hazards that may compromise it. The aim of this study was to identify microbiological, chemical and physical hazards of drinking water from public wells which may impact human health, and to evaluate the results of routine drinking water analysis, not taking into account the national legislation, but the risk management approach. Material and Methods. Drinking water was sampled from 20 public wells in South Backa District and analyzed at the Institute of Public Health of Vojvodina according to accredited national standards during 2016. The drinking water hazards were defined according to international recommendations. Risk assessment was done using a semiquantitative approach, which assesses the like?lihood and consequences of a hazard, rating the risks as low, medium, high and very high. Results. Of 218 drinking water samples, according to national regulations, only 10% were healthy for consumption. The recognized hazards were thermotolerant coliforms (especially Escherichia coli), enterococci (genus Streptococcus), Pseudomonas aeruginosa, Proteus species and nitrates above legal limits. The risk was rated high, with an impact on the morbidity of sensitive populations in 2/3 of controlled public wells, in 1/3 as medium, leading to abandonment of drinking water sources. Conclusion. The proposed risk assessment methodology is a tool that provides easily understandable and clear information on the possibility of using public wells with a consequent impact on human health. The management of drinking water safety is the greatest challenge, systematically prioritizing risk assessment of drinking water from public wells for the health of the population in the Republic of Serbia.

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.

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.

An estimated 2,300 people became seriously ill and seven died from exposure to microbially contaminated drinking water in the town of Walkerton, Ontario, Canada in May 2000. The severity of this drinking water disaster resulted in the Government of Ontario calling a public inquiry by Mr. Justice Dennis O’Connor to address the cause of the outbreak, the role (if any) of government policies in contributing to this outbreak and, ultimately, the implications of this experience on the safety of drinking water across the Province of Ontario. The circumstances surrounding the Walkerton tragedy are an important reference source for those concerned with providing safe drinking water. Although some circumstances are obviously specific to this epidemic, others are uncomfortably reminiscent of waterborne outbreaks that have occurred elsewhere. These recurring themes suggested the need for attention to broad issues of drinking water security and they present the challenge for how drinking water safety can be managed to prevent such tragedies in the future.

Lead (Pb) is a typical contaminant in water with adverse effects on human health. Hong Kong’s incident of drinking water contamination by Pb in 2015 caused severe public concerns regarding drinking water safety. Conventional treatment methods for Pb removal generally require electricity, chemical dosage, and considerable time and space, which significantly restrict their use for rapid water purification under emergency situations. In this study, a polyvinyl alcohol/polyacrylic acid (PVA/PAA) composite nanofibrous membrane was developed for the rapid and effective removal of Pb from water. The PVA/PAA membrane had a high water permeability of 550 L/m2/h/kPa - 710 L/m2/h/kPa, which allowed the filtration to be driven by gravity (e.g. with a water height of 10.0 cm). The membrane showed consistently high removal efficiency of Pb (> 95%) with a volumetric loading up to 3000 L/m2. This high removal efficiency was attributed to the combined effects of complexing and electrostatic attraction between Pb and PAA. An esculent citric acid was used to regenerate the exhausted PVA/PAA membrane. The regenerated membrane maintained its removal efficiency of Pb over a five-cycle filtration. These results imply that the PVA/PAA composite membrane can be repeatedly used in electricity-free filtration devices for rapid elimination of Pb under emergency situations.

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.
