The contract was undertaken in response to an invitation to tender from the NRA, the objective of which was to collect samplps of epilithic diatoms from sites identified by the NRA, to determine the degree of eutrophication or pollution at those sites using a range of methods, and to make recommendations for future monitoring. Although almost all the monitoring systems classified the sites as moderately to strongly eutrophic, the assessments of pollution varied considerably. Between site resolution differed markedly according to the system employed, and even with interpretation of the particular system. Evaluation of sites also differed if the ecological tolerance assigned to a particular species varied with author.
