2 This paper draws on lessons from a UK case study in the management of diffuse microbial pollution from grassland farm systems in the Taw catchment, south west England. We report on the development and preliminary testing of a field-scale faecal indicator organism risk indexing tool (FIORIT). This tool aims to prioritise those fields most vulnerable in terms of their risk of contributing FIOs ...

Downstream water quality had been monitored monthly for 212 years before the clearcut, during the clearcut, and for two years following the clearcut. The objective of this paper was to test the hypothesis that c...
