The key barriers used in water treatment to prevent the passage of pathogens from raw water to finished drinking water are:
- Source protection
When a treatment plant is optimized, careful attention must be paid to both physical removal and disinfection. It is also important when making an assessment to look at the source of supply, considering potential contamination sources, and evaluating possible source protection/management strategies and monitoring practices.
The following information is intended to aid supply source and treatment plant facilities in evaluating their operational effectiveness for protection against microbial contamination and waterborne disease.
