Fauna Polluted dangerous absent or seriously substance restricted Notes relating to classification scheme a - Based on 3 years data, minimum of 12 samples, unless there has been a significant change in circumstances (eg a discharge eliminated) which justifies a 1 year assessment. - Estimation of percentiles for more than 19 samples to be by the non-parametric Wiebull Method. Otherwise the parametric method is used, assuming DO and pH are normal distributions, and BOD and Ammonical Nitrogen are log normal. - For pH the 5, 10 and 95 %iles must be determined from the 3 years data and compared with the class determining limits in the Classification Table. Again, where there are more than 19 samples the percentiles should be estimated by the non- parametric Wiebull Method. Otherwise, the parametric percentile estimation must be made, using the method of moments, and an assumed normal distribution. b - RIVPACS assessment based on data for 1 year, preferably 3 samples (Spring, Summer, Autumn), minimum of 2 (Spring and Summer). c - Based on 1 year’s monitoring data, preferably 3 samples, minimum 2. The overall class to be determined from the mean field score and mean ASPT of the individual samples. d - Aesthetic conditions to be based on 1 year’s monitoring data and will be assessed and recorded during biological and/or chemical visits. The points should be representative of the general quality of the watercourse reach. Aesthetic contamination to be assessed as either discharge related (List A) or general (List B). List A contaminants List B contaminants Sewage derived litter and solids, including General non sewage derived litter - faeces Builders waste - toilet paper Gross litter, including - contraceptives - shopping trolleys - sanitary towels - furniture - tampons - motor vehicles - cotton buds - road cones Oils - bicycles/prams Non natural foam, scum or colour Sewage fungus Sewage or oily smells e - No List A contaminants, possibly minor List B litter present. f - Traces of List A and /or occasional List B contamination, especially at easy access points. g - List A contamination widespread and/or occasional conspicuous quantities, and/or gross amounts of List B contamination. Likely to be the cause of justified public complaints.
