Faecal indicator organism concentrations and catchment export coefficients in the UK

Kay, David; Crowther, John; Stapleton, Carl M.; Wyer, Mark D.; Fewtrell, Lorna; Anthony, S. G.; Bradford, M. A.; Edwards, A.; Francis, Carol; Hopkins, M.; Kay, C.; McDonald, Adrian T.; Watkins, John; Wilkinson, J. (2008-05)

Characterisation of faecal indicator organism (FIO) concentrations and export coefficients for catchments with particular combinations of land use and under specific climatic regimes is critical in developing models to ...
Faecal indicator organism concentrations in sewage and treated effluents

Kay, David; Crowther, John; Stapleton, Carl M.; Wyer, Mark D.; Fewtrell, Lorna; Edwards, A; Francis, F.; McDonald, Adrian T.; Watkins, John; Wilkinson, J. (2008-01)

The importance of faecal indicator organism (FIO) fluxes within drainage basins is increasing as the European Union (EU) Water Framework Directive and the United States Clean Water Act place requirements on regulators to ...
Faecal indicators and pathogens: expanding opportunities for the microbiology community

Kay, David; Crowther, John; Davies, Cheryl Margaret; Edwards, Anthony; Fewtrell, Lorna Jane; Francis, Carol; Kay, Christopher David; McDonald, Adrian T.; Stapleton, Carl Michael; Watkins, John; Wyer, Mark David (Royal Society of Chemistry, 2012)

Water regulation world-wide is moving to a new and challenging paradigm characterised by integrated assessment and management of multiple pollution loadings within drainage basins. This is seen in the European Water Framework ...
Generic modelleing of faecal indicator organism concentrations in the UK

Crowther, John; Hampson, Danyel; Bateman, Ian; Kay, David; Posen, Paulette; Stapleton, Carl Michael; Wyer, Mark David (2011-06-20)

To meet European Water Framework Directive requirements, data are needed on faecal indicator organism (FIO) concentrations in rivers to enable the more heavily polluted to be targeted for remedial action. Due to the paucity ...
Impacts of agriculture on water-borne pathogens

Kay, David; Crowther, John; Edwards, Anthony; Fewtrell, Lorna Jane; Francis, Carol; Kay, Christopher David; McDonald, Adrian T.; Stapleton, Carl Michael; Watkins, John; Wyer, Mark David (Royal Society of Chemistry, 2012)
Microbial source tracking: a forensic technique for microbial source identification?

Crowther, John; Hindle, Terry; McDonald, Adrian T.; Walters, Martin; Wyer, Mark D.; Gawler, Andrew; Stapleton, Carl M.; Kay, David (2007)

As the requirements of the Water Framework Directive (WFD) and the US Clean Water Act (USCWA) for the maintenance of microbiological water quality in ‘protected areas’ highlight, there is a growing recognition that integrated ...
Predicting faecal indicator fluxes using digital land use data in the UK's sentinel Water Framework Directive catchment: the Ribble study

Stapleton, Carl M.; Crowther, John; Kay, David; Wyer, Mark D. (2005-10)

The Ribble drainage basin is the single UK sentinel study area chosen for examining the implementation of the EU Water Framework Directive (WFD 20/60/EC). The study which has generated the data for this paper was initiated ...
Predicting microbial pollution concentrations in UK rivers in response to land use change

Hampson, Danyel; Crowther, John; Bateman, Ian; Kay, David; Posen, Paulette; Stapleton, Carl M.; Wyer, Mark; Fezzi, Carlo; Jones, Philip; Tzanopoulos, Joseph (2010-09)

The Water Framework Directive has caused a paradigm shift towards the integrated management of recreational water quality through the development of drainage basin-wide programmes of measures. This has increased the need ...
Quantification and control of microbial pollution from agriculture: a new policy challenge?

Crowther, John; Wilkinson, J.; Stapleton, Carl M.; Hopkins, M.; Kay, C.; Wyer, Mark D.; Kay, David; McDonald, Adrian T.; Watkins, John; Francis, Carol; Fewtrell, Lorna (2008-04-01)

Faecal indicator organisms (FIOs) are commonly used to quantify pollution of public health significance. Health protection, as indexed by FIO control, is a central aim of new ‘catchment-scale’ water quality management ...
Quantitative catchment profiling to apportion faecal indicator organism budgets for the Ribble system, the UK's sentinel drainage basin for Water Framework Directive research

McDonald, Adrian T.; Wyer, Mark D.; Stapleton, Carl M.; Francis, Carol; Kay, David; Watkins, John; Crowther, John; Greaves, J.; Wither, A. (2008-06-01)

Under the EU Water Framework Directive (WFD) 20/60/EC and the US Federal Water Pollution Control Act 2002 management of water quality within river drainage basins has shifted from traditional point-source control to a ...
Quantitative microbial source apportionment as a tool in aiding the identification of microbial risk factors in shellfish harvesting waters: the Loch Etive case study

Stapleton, Carl M.; Kay, David; Magill, Shona H.; Wyer, Mark D.; Davies, Cheryl; Watkins, John; Kay, Chris; McDonald, Adrian T.; Crowther, John (2011-02)

Sanitary surveys of shellfish harvesting waters are now a routine component of regulatory monitoring. These provide a qualitative appraisal of potential pollutant sources impacting on shellfish microbial quality. The ...
Reducing fluxes of faecal indicator compliance parameters to bathing waters from diffuse agricultural sources: The Brighouse Bay study, Scotland

Crowther, John; Aitken, M.; Dickson, I.; Kay, David (2007-05)

The European Water Framework Directive requires the integrated management of point and diffuse pollution to achieve ‘good’ water quality in ‘protected areas’. These include bathing waters, which are regulated using faecal ...
