  • Drinking Water Resource Protection, Germany

    Reference Project: Drinking Water Resource Protection, Germany In the catchment area of a major drinking water supplier in western Germany increasing nitrate concentrations were noticed within a deep water-bearing layer. Although high nitrate concentrations, resulting from regional intensive application of fertilizers, were known from shallow layers in the area, they were new to the deep ...

  • European water policies and human health — Combining reported environmental information

    Society depends on the satisfactory and sustainable management of water. Historically, the primary purpose of water treatment was to protect human health, through reducing disease being transmitted through water. Subsequent measures to address environmental concerns have broadened our expectations of what water and waste water treatment should deliver. This report considers three pieces of EU ...

  • Drinking water application notes

    The Safe Drinking Water Act (SDWA) was passed in 1974 to protect the nation's public drinking water supply. The law allowed for the EPA to regulate the amount of certain contaminants that a body of water can contain. The Application Notes listed are designed to extract organic compounds in municipal drinking water for ...

  • Drinking Water Analysis Guide

    Public Water Systems (PWS), regulated by the United States Environmental Protection Agency (USEPA), provide drinking water to 90% of Americans. Water systems and laboratories testing drinking water for Safe Drinking Water Act (SDWA) compliance must be certified and must use USEPA approved methods, which are developed by the USEPA, other government agencies, universities, consensus method ...

  • Drinking Water Standards

    The most important point of departure for drinking water standards is the World Health Organisation Guidelines for Drinking Water Quality. These are widely used throughout the world with the exception of parts of North America. WHO’s Guidelines have evolved over a period of 50 years from standards to guidelines, reflecting the fact that they have no legal force. The WHO emphasises that it ...

  • Glyphosate and AMPA in drinking water

    Carcinogenic or not? The broad-spectrum herbicide glyphosate is used all over the world in agriculture. Alongside farming, the chemical is also used for weed-killing in domestic gardens and in public and private spaces kept free from «vegetal invasion», such as railway tracks. Glyphosate has been used since the 1970s in pesticides and was hitherto thought to be harmless at ...

  • Water, water everywhere: But is there enough to drink?

    Original story at MIT News At MIT, experts address the challenges of supplying clean, safe water to a growing world population. The challenge of supplying clean, safe drinking water to an expanding world population comes down to money, MIT economist Franklin Fisher ...

  • Towards an effective protection of groundwater resources: putting policy into practice with the drinking water protection file

    Groundwater in the Netherlands is a major resource for drinking water. As such it must be carefully monitored and managed. Evaluation of the European Water Framework Directive (EU-WFD) showed that protection of this valuable resource needs improvement. The Drinking Water Protection File identifies necessary measures needed per water abstraction site. The Protection File is part of the Dutch ...

  • Report to Congressional Requestors: Drinking Water

    Every day in the United States, at least 2 billion gallons of fluids are injected into over 172,000 wells to enhance oil and gas production, or to dispose of fluids brought to the surface during the extraction of oil and gas resources. These wells are subject to regulation to protect drinking water sources under EPA’s UIC class II program and approved state class II programs. Because much ...

  • 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 ...

  • Treatment plant protected by effluent monitor at major drinks factory

    The installation of a BioTector continuous TOC (Total Organic Carbon) monitor to police the front end of Cobevco’s wastewater treatment plant has enabled tight control of the treatment process. Delivering results 20 times faster than laboratory techniques, the monitor at the Elton facility in Cheshire provides advance notice of organic overload so that the plant is able to instantly divert ...


  • Development of a risk-based approach for better protection of drinking water catchments in Flanders (Belgium)

    Around 70% of the drinking water produced by De Watergroep (a Belgian public water company) is extracted from 83 groundwater pumping sites. To control the risks that endanger the drinking water supply and for the groundwater extracted to be as pure as possible, a risk-based approach for the protection of the catchment areas is developed, as part of the water safety plans. The approach ...

  • Environmental protection

    An analysis of the lighting industry shows a significant shift from the use of incandescent bulbs to fluorescent bulbs. Incandescent bulbs use more fossil fuel energy, cost more and are less effective than fluorescent bulbs, which produce more lumens. Usage of fluorescent bulbs, however, is not entirely without risk because they contain mercury, a chemical compound that can have debilitating ...


  • New DWI guidelines for UV drinking water disinfection

    atg UV, has seen increasing interest in the application of UV systems for the treatment of drinking water applications since the UK Drinking Water Inspectorate (DWI) released their ‘Guidance on the use of Ultraviolet (UV) Irradiation for the Disinfection of Public Water Supplies' February 2010. With systems treating in excess of 2000 m3/hr daily, Ultraviolet disinfection is no longer an ...

  • Bonn Charter principles for safe drinking water

    In the mid 1990’s a number of initiatives across the world began to question whether the so called “end of pipe” standard setting approach to protecting drinking water quality was the right way forward for the 21st century. This discussion began to come together in two main international forums. Firstly the massive task of updating the highly influential 3rd revision of the ...

  • 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): ...

  • Rethinking aesthetic guidelines for manganese and iron in drinking water

    Manganese and iron are both internationally known causes of aesthetic issues in drinking water, however, there are limited data supporting their specific aesthetic guidelines, of which typical values are 0.05 mg/L Mn and 0.3 mg/L Fe. This study aims to clarify the concentrations at which off-flavors and off-colors caused by manganese and iron may be detected by consumers. Triangle tests of ...

  • Perceived agricultural runoff impact on drinking water

    Agricultural runoff into surface water is a problem in Australia, as it is in arguably all agriculturally active countries. While farm practices and resource management measures are employed to reduce downstream effects, they are often either technically insufficient or practically unsustainable. Therefore, consumers may still be exposed to agrichemicals whenever they turn on the tap. For rural ...
