A Community Water System with an outstanding record should have a sanitary survey performed how often?

• A. Every 5 years
• B. Every 3 years
• C. Every 7 years
• D. Every 1 year

Answer: (A)

Sanitary surveys check a community water system’s source, treatment, distribution, and management to catch any potential problems that could affect water safety. The frequency is tied to how well the system is performing. If the record is outstanding, the survey can be spaced further apart, typically every five years. This provides ongoing oversight while avoiding unnecessary frequency for a well-run system. Shorter intervals are used when there are findings or higher risk, while longer intervals than five years aren’t standard for a system with an excellent track record. So, the best interval is every five years.
