SUMMARY A vailable national guidelines for disinfection practice, and for the examination of bacteriological quality, are reviewed, together with the legislative requirements of the EC ‘Drinking Water’Directive. Problems of impracticability, vagueness, and ambiguity are identified. Experience of the maintenance of bacteriological quality in large, lowland, surface water and ground‐water supply areas is given with reference to the behaviour of disinfectant residuals, trihalomethanes, nitrite, and aesthetic parameters. The way forward in terms of the management of distribution systems and water treatment is discussed.
