Assessing waterborne health risks through quantitative risk assessment models

"In drinking water treatment, a balance must be maintained between the highest microbial safety, while limiting the long term chemical risk from disinfection by-products. To achieve this, Quantitative Microbial Risk Assessment (QMRA) models are used to attain a level of acceptability in engineering and public health. Models for QMRA are being increasingly used internationally by regulatory agencies. The objective of applying these models is to help define when safe is 'safe enough.' It is a systematic and science-based approach to warrant that systems will deliver safe water and efficient safety management"--Page 1.
