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 ...

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 ...

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 ...

Effect of NaCl on antimony and phthalate compounds leached from PET bottles
Nowadays polyethylene terephthalate (PET) bottles are commonly used as food containers as they are lightweight. PET bottles contain antimony (Sb) and phthalate compounds. In contact with food, antimony and phthalate molecules could migrate from the inner surface of a PET bottle to the food. Therefore, we studied the effect of NaCl concentration in PET bottles on the leakage of antimony and ...

United States EPA Method 415.3
Abstract In order to ensure drinking water is safe for human consumption, water treatment plants often add disinfectants to drinking water. The disinfectants, such as chlorine, protect drinking water from pathogens, disease causing organisms, but can react with naturally occurring materials in the water to form byproducts that may be harmful for consumption. The United States Environmental ...

A systematic literature review of the enabling environment elements to improve implementation of water safety plans in high-income countries
Effective risk management helps ensure safe drinking water and protect public health. Even in high-income countries, risk management sometimes fails and waterborne disease, including outbreaks, occur. To help reduce waterborne disease, the WHO Guidelines for Drinking Water Quality recommend water safety plans (WSPs), a systematic preventive risk management strategy applied from catchment to ...

1700 miles of the keystone Xl Pipeline: A state, federal and international regulatory concern
Regulatory compliance at the state and federal level grows infinitely more complex when the laws and regulations of six U.S. states, U.S. federal regulations, and the Canadian regulatory regime are intertwined. TransCanada’s proposed Keystone XL Pipeline, currently awaiting approval from the U.S. Department of State, is gaining as much attention for its regulatory complexity as it is for ...

Reports: Rural U.S. drinking water must be protected
State and federal officials must act to safeguard drinking water supplies throughout the United States, particularly in rural areas and small towns, according to investigative reports published in December 2016. Lead contamination may be affecting 4 million or more Americans, according to reports by USA TODAY and Reuters. Water systems in small communities are not scrutinized as closely as ...

Water shortages and extreme events: a call for research
Water shortages as a result of extreme weather events, such as flooding and severe cold, have the potential to affect significant numbers of people. Therefore, the need to build robust, coordinated plans based on scientific evidence is crucial. The literature review outlined in this short communication was conducted as part of a joint Drinking Water Inspectorate and Health Protection Agency ...

Safety of packaged water distribution limited by household recontamination in rural Cambodia
Packaged water treatment schemes represent a growing model for providing safer water in low-income settings, yet post-distribution recontamination of treated water may limit this approach. This study evaluates drinking water quality and household water handling practices in a floating village in Tonlé Sap Lake, Cambodia, through a pilot cross-sectional study of 108 households, ...

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 ...

Icelandic experience with water safety plans
The aim of this study was to investigate accumulated experience with water safety plans in one of the first countries to adopt systematic preventive management for drinking-water safety. Water utilities in Iceland have had a legal obligation since 1995 to implement a systematic preventive approach to secure safety of drinking water and protect public health. The water utilities responded by ...

Liveability and the Water Sensitive City
This report establishes the foundation for ongoing research by the CRC in linking urban water management and urban liveability. The study commenced through the Science-Policy Partnership for Water Sensitive Cities, a joint initiative of Monash University’s then Centre for Water Sensitive Cities (now Monash Water for Liveability Centre) and Victoria’s Department of Sustainability and ...

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 ...

Sustainable community-based drinking water systems in developing countries: stakeholder perspectives
Over the past 25 years, stakeholders have become increasingly involved in the development and management of community-based projects. This paper presents the results of a study aimed at establishing stakeholder perspectives and priorities for sustainable community-based drinking water systems (CBDWS). The stakeholders have agreements and biases, which require an improved understanding of the ...

Changes in chemical and physical properties of stream water across an urban-rural gradient in western Georgia
The Middle Chattahoochee River Watershed in western Georgia is undergoing rapid urban development. Consequently, Georgia’s water quality is threatened by extensive development as well as other land uses such as grazing. Maintenance of stream water quality, as land development occurs, is critical for the protection of drinking water, biotic integrity, and stream morphology. A two-phase, ...

Development of point-of-use water disinfection technology using ceramic water filter and electrochemical hybrid system
The efficiency of water disinfection using a ceramic water filter and electrochemical hybrid system was investigated. Escherichia coli O157:H7 was effectively inactivated even when a storage battery, charged using a solar panel device, was used for the electrolysis process. During electrolysis, the rate of microbial inactivation was higher at higher initial Cl− concentrations. This was ...
