Catchment microbial dynamics and modelling

 

CREH has completed over 50 major catchment surveys for the UK regulators, water companies and governments since 1998.


This work has produced the first microbial export coefficients world-wide for common  land uses.


Initial export coefficient models for prediction of microbial impacts on bathing and shellfish waters have been used for sanitary surveys of key resource sites in projects funded by Defra, UKWIR and the Environment Agency.


Recent work for SEPA, the Scottish Government and DEFRA has focused on the efficacy of sustainable best management practices (BMPs) by the farming sector designed to reduce microbial pollution from the livestock sector.


Major EU funding, awarded under the FP7 programme, is developing catchment model systems to predict viral pathogen flux in catchment systems (see www.Viroclime.org).


The application and operational utility of molecular methods in microbial enumeration for pathogen assessment and microbial source tracking have been examined in projects funded by the EU, the Environment Agency and the UK water industry through UKWIR (see www.Virobathe.eu and www.deliveringhealthywater.org)
