To protect public health, regulators require performance measures, which demonstrate that water is safe to drink and free of faecal contamination. This paper discusses the role of total coliforms (as distinct from E.coli/faecal coliforms) in a risk management approach to drinking water protection. A two tiered matrix that integrates with risk management and quality system components of the drinking water management system is promoted. The matrix, which includes total coliforms as one of its elements, is proposed as means of integrating the risk management with traditional compliance based on numerical standards.
