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 ...

A strategic approach for Water Safety Plans implementation in Portugal
Effective risk assessment and risk management approaches in public drinking water systems can benefit from a systematic process for hazards identification and effective management control based on the Water Safety Plan (WSP) concept. Good results from WSP development and implementation in a small number of Portuguese water utilities have shown that a more ambitious nationwide strategic approach ...

Supporting the Water Safety Plan (WSP) approach with the Failure Experience Improvement System (FEIS)
The Water Safety Plan (WSP) aims to ensure safe drinking water through risk assessment and preventive risk management which cover all steps of the water supply from catchment to the consumer. This approach requires a comprehensive hazard assessment including the identification and prioritisation of potential hazardous events. The Failure Experience Improvement System (FEIS) supports this key step ...

Enteric viruses in New Zealand drinking-water sources
This study determined whether human pathogenic viruses are present in two New Zealand surface waters that are used as drinking-water sources. Enteric viruses were concentrated using hollow-fibre ultrafiltration and detected using PCR for adenovirus (AdV), and reverse transcription PCR for norovirus (NoV) genogroups I-III, enterovirus, rotavirus (RoV) and hepatitis E virus (HEV). Target viruses ...

Groundwater arsenic in Chimaltenango, Guatemala
In the Municipality of Chimaltenango, Guatemala, we sampled groundwater for total inorganic arsenic. In total, 42 samples were collected from 27 (43.5%) of the 62 wells in the municipality, with sites chosen to achieve spatial representation throughout the municipality. Samples were collected from household faucets used for drinking water, and sent to the USA for analysis. The only site ...

An evaluation of sampling methods and supporting techniques for tackling lead in drinking water in Alberta Province
A demonstration project evaluated a range of sampling methods and supporting techniques for tackling lead in drinking water in Alberta Province, with the cities of Calgary and Edmonton as case studies. The sampling protocols specified by Health Canada in their 2009 guidance were confirmed to need further improvement and clarification; these sampling protocols produce results that are subject ...

Water Safety Plan demonstration projects in Latin America and the Caribbean: lessons from the field
A Water Safety Plan (WSP) is a preventive, risk management approach to ensure drinking water safety. This emerging methodology is being increasingly applied in both industrialized and lower income countries worldwide. In 2006, the U.S. Centers for Disease Control and Prevention (CDC) and other local, national, and international partners in Latin America and the Caribbean (LAC) initiated a series ...

What is a Water Safety Plan?
Water is an essential basis in many industrial processes and a Water Safety Plan can prevent and manage threats to the water supply for those processes from the catchment to the process itself. Industries that use large quantities of water include brewery and carbonated beverage water; dairy industries; textile manufacturing; pulp and paper mills; oil and gas; the pharmaceutical industry and ...

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 ...

Investigation of water consumption patterns among Irish adults for waterborne quantitative microbial risk assessment (QMRA)
Microbial and chemical contamination of drinking water supplies can cause human health problems. Microbial pathogens are of primary concern and quantitative microbial risk assessment (QMRA) is employed to assess and manage the risks they pose. Estimates of drinking water consumption, or distributions, are required to assess levels of waterborne pathogen exposure. To establish distributions for ...

From international developments to local practice: Germany's evaluation and dialogue process towards Water Safety Plan implementation
The third edition of the WHO Guidelines for Drinking-water Quality establishes a ‘Framework for Safe Drinking-water’ that promotes a risk assessment and risk management approach called Water Safety Plan (WSP). In Germany, the discussion on the WSP approach started with significant scepticism by various stakeholders questioning its added value in light of the high quality and service level of ...

Systematic risk management approach of household drinking water from the source to point of use
The water safety plan (WSP) approach is being widely adopted as a systematic approach to improving the safety of drinking water. However, to date, the approach has not been widely used for improving the safety of drinking water in those settings where people have to collect water away from their home. Most rural areas in South Africa still consume unsafe water despite WSP implementation and ...

Application of a risk management framework to a drinking water supply augmented by stormwater recharge
The Blue Lake is an important water resource for the city of Mount Gambier and the surrounding region, primarily as the drinking water supply source, but also as a tourist attraction. Mount Gambier’s stormwater is discharged directly via drainage wells into the unconfined, karstic Gambier Limestone aquifer, which in turn provides the majority of recharge to Blue Lake. Discharge of urban runoff to ...

Evolution of water recycling in Australian cities since 2003
The prolonged Australian drought which commenced in 2002, and the agreement between Australia's Commonwealth and States/Territories governments to progress water reform through the National Water Initiative, has resulted in many new recycling projects in Australia's capital cities. Dual reticulation systems are being advanced in new subdivision developments in Sydney, Melbourne and Adelaide. ...

Water safety planning for small water supply systems: the framework and control measures
A water safety plan (WSP) is a preventive comprehensive risk assessment and management approach to ensuring the safety of a drinking water supply from source to tap for public health protection. The concept was introduced in the last decade in international guidance documents and has been applied widely across a varied range of water supply systems, particularly, the public water utilities ...
