  • Homeland Security for Drinking Water Supplies

    As it has done with other jurisdictions, Congress has recently passed legislation aimed at protecting our nation's drinking water resources. Historically, water supply protection has been a high priority, including reservoir protection, continuous monitoring, and secure and redundant facilities to ensure an uninterrupted supply of drinking water. The Clean Water Act (1972), requires pollution ...

  • Lead in Drinking Water for small supply systems

    The problem of lead in drinking water is most-publicized for the larger water supply systems of Cities and Towns, particularly the older districts, where lead piping was often used to connect houses to a municipal water supply system and for internal plumbing, unto the early 1980s (generally). The problem is more closely associated with the longer established industrialized and urbanized ...

  • Managing water quality impacts from drought on drinking water supplies

    Droughts, which are difficult to predict, are a natural feature of the hydrology in most regions. Climate change, however, has the potential to increase the frequency and magnitude of future droughts. While the lack of water availability during droughts is widely publicized, there are equally severe water quality impacts that occur during and after droughts as well. Recent droughts have led to ...

  • UK experience in the monitoring and control of lead in drinking water

    At the zonal scale (e.g. a city or town), random daytime (RDT) sampling succeeded in demonstrating both the need for corrective action and the benefits of optimised orthophosphate dosing for plumbosolvency control, despite initial concerns about sampling reproducibility. Stagnation sampling techniques were found to be less successful. Optimised treatment measures to minimise lead in drinking ...

  • Quantifying micro-organism removal for safe drinking water supplies

    Over the past ten years the management of microbiological drinking water quality in The Netherlands has shifted from curative administration toward a more preventative strategy. This shift in policy came as a result of the findings of reports from other developed countries which highlighted the risk from persistent pathogens such as Cryptosporidium, Giardia, some enteroviruses; and the pathogenic ...

  • Assessing protozoan risks for surface drinking water supplies in Nova Scotia, Canada

    Protozoa, such as Cryptosporidium parvum and Giardia lamblia, pose a human health risk when present in drinking water. To minimize health risks, the Nova Scotia Treatment Standards for surface water and groundwater under the direct influence of surface water require a 3-log reduction for Giardia cysts and Cryptosporidium oocysts. This study ...

  • National rural drinking water monitoring: progress and challenges with India's IMIS database

    National drinking water programs seek to address monitoring challenges that include self-reporting, data sampling, data consistency and quality, and sufficient frequency to assess the sustainability of water systems. India stands out for its comprehensive rural water database known as Integrated Management Information System (IMIS), which conducts annual monitoring of drinking water coverage, ...

  • Evaluation of drinking water quality in a water supply distribution network based on Grey correlation analysis

    The lack of access to clean drinking water adversely affects public health and life expectancy in many developing countries. However, not all cities' drinking water can currently meet drinking water standards. Therefore, determining reasonable water quality changes and the influence of various factors on water quality is important for improving drinking water quality. The objective of this study ...

  • Organisational arrangements and drinking water quality

    This paper discusses the findings of a research project which explored the impact of varying organisational arrangements on drinking water quality in England and Wales, and the Republic of Ireland. It is established that drinking water quality has been of a consistently higher standard in England and Wales in comparison with the Republic of Ireland. It is also demonstrated that the associated ...

  • Testing and developing energy harvester systems for operation of energy-self-sufficient measurement and control units in drinking water supply

    In recent years, wireless measurement and control units have become more popular for monitoring water distribution systems in the drinking water supply. Electric power supply for a higher number of devices through fixed connections to the public electrical grid is technically complex and requires large investments. Powering monitoring devices, which are installed in areas where electrical ...

  • Supply system factors associated with microbiological drinking water safety in regional New South Wales, Australia, 2001–2007

    Aim: To determine factors associated with microbiological safety of public drinking water systems in regional New South Wales (NSW), Australia. Method: We analysed 107,000 end-user drinking water samples for an association between detection of Escherichia coli and drinking water system features, sample year and season using NSW Health Drinking Water Monitoring Program data, 2001–2007. We used ...

  • Grundfos Alldos provides clean drinking water in Athens

    In time for the Olympic Games, Grundfos Alldos equipped the four existing Athens water treatment plants in Galatsi, Melindi, Kiourka and Aspropyrgos with state-of-the-art disinfection systems and put them into operation. In order to ensure that everything ran smoothly, a cutting-edge SCADA system was installed for remote monitoring. This means that plants, sometimes 40 km apart, can be monitored ...


  • Surveillance and Improvement of Peruvian Drinking Water Case Study

    The surveillance and quality control of public water supplies are vital prerequisites for the protection of public health. In practice however, the two activities of surveillance and quality control are often confused and inadequately implemented, especially in the case of surveillance in less developed countries. The two are clearly distinguished by the World Health Organization (1984): ...
