Increasing attention is being given to the presence of viruses in groundwater. Whilst there have been a few well documented outbreaks, it has been suggested that viruses may also contribute to a low level of sporadic illness in communities served by groundwater supplies. This review assesses the evidence for the occurrence of viruses in groundwater and the associated health risk. It also considers the various routes of contamination and examines factors known to influence virus fate and behaviour in the underground environment. The adoption of a multiple barrier approach, which combines the benefits of source protection and effective disinfection, is seen as an effective strategy to minimise the risk posed by viruses in groundwater This approach can be strengthened by developing a sanitary survey that provides a rigorous and numeric site-specific risk assessment.

Cryptosporidium spp. in animal hosts with potential for impacting on sources of drinking water in the UK

Over recent years, an increasing number of new species of Cryptosporidium have been discovered from a range of different animal hosts and molecular methods have greatly improved our knowledge of the public health significance posed by those species recognised. Research has shown that many species are not confined to a single host and that variation in pathogenicity exists within species known to infect humans. In light of these developments, this special topic review was undertaken to provide water companies with a current understanding of risks posed by this organism. It will permit more accurate sanitary surveys for identifying catchment control measures to reduce the risk from Cryptosporidium and the burden on water treatment.

GAC Quality and Operational Management including Regeneration, alternative adsorbents, ozone and alternative oxidation technologies

Published Date: 01/08/2017

The purpose of this project was to gather information to help optimise GAC system performance and to inform the selection of water treatment strategies to deal with the threats posed by emerging pesticides. This UKWIR project produced:

(i) A ‘Guidance Manual’ which presents a critical review of water companies’ use of GAC (and ozone) over the past 20 years to identify best practices, in tandem with a review of available alternative design, monitoring and management solutions; it included the key parameters of interest, as they were identified, regarding current and future challenges faced within drinking water treatment.

(ii) A report ‘Review of emerging adsorption media and advanced oxidation processes’, which identified 26 technologies and determined whether these technologies could provide a cost-effective solution to water quality issues; and to design an information framework for developers, manufacturers and suppliers.

DWQ Big question - how can we achieve 100% compliance with drinking water standards at point of use by 2050?

Drinking Water Quality Big Question:  How Can We Achieve 100% Compliance with Drinking Water Standards at Point of Use by 2050?

UKWIR has undertaken an ambitious programme to define longer term, strategic research needs in key areas via its Big Questions initiative.  To support the development of this drinking water quality (DWQ) Big Question, a community-owned list of prioritised research needs to achieve 100% compliance for drinking water quality was produced. 

The innovations needed in drinking water quality were evaluated from source to tap to capture the inter-dependencies within water systems and to identify the best intervention options to balance risk reduction and cost.  The approach for the prioritisation of DWQ research needs considered the degree of current knowledge, including uncertainty and gaps, and mapped that against the degree of risk associated with each contaminant.   Contaminants with lowest knowledge and highest risk were prioritised as the focus of future research at an interactive workshop.  The prioritised issues included those where little occurrence data exists, where there is a need to increase fundamental understanding, or where both occurrence data and understanding are lacking.
