This study was undertaken to determine the causes of non-compliance with the designated River Quality Objective's (FQO) in the Kenn sub-catchment of the River Exe. Aquatic macroinvertebrate samples were taken from 16 sites on the main River Kenn and its principle tributary, Splatford Brook, to locate areas of poor water quality in the Kenn catchment. The sources of pollution in these areas were traced by taking further samples and identifying indicator taxa in the field. Chemical samples were collected during high river flows at the same main river sites sampled in the initial biological survey and at sites downstream of identified areas of poor water quality. Two continuous water quality monitors were installed in the catchment. High Biochemical Oxygen Demand (BOD) concentrations and suspended solids concentrations were shown to occur in the majority of the Kenn catchment after heavy rainfall.
