SEPA publishes a long-term river water quality indicator, based on a network of sites covering 253 water bodies (rivers or sections of rivers). This indicator is based on a consistent set of five water quality parameters which are sensitive to organic pollution, nutrients and toxic substances, and which provide a measure of species diversity across approximately 10% of all water bodies. Monitoring In 2011, the Scottish Environment Protection Agency (SEPA) established an indicator of river water quality based on a network of sites covering 253 water bodies (rivers or sections of rivers), which account for approximately 10% of all water bodies. The indicator is based on a consistent set of five water quality parameters which are sensitive to organic pollution, nutrients and toxic s

Further technical guidance This page brings together a number of ancillary guidance documents and previous email bulletin information relating to modelling of marine fish-farms for CAR licence applications. Auxiliary biomass sampling transect In areas where the tidal residual current is weak, the auxiliary transect (site-specific sampling 2) may be aligned along a bearing reciprocal to the primary

Marine aquaculture modelling Computer modelling is used as a guide to determining licensed discharge quantities of anti-parasitic chemicals and organic waste arising from marine fish-farm operations. The modelling tools promoted by SEPA provide robust predictions in most cases, requiring relatively little site-specific information. Nevertheless, the quality of the model outputs is dependent upon g
