Which policy governs monthly bacteriological analyses of emergency potable water tanks?

• A. CI 1000.9
• B. CIM 6240.5
• C. CIM 6000.1
• D. CIM 6240.4

Answer: (B)

Understanding how the Coast Guard keeps emergency drinking water safe hinges on specifying who tests what and how often. CIM 6240.5 is the rule that lays out the requirements for bacteriological testing of emergency potable water tanks, including how often you test (monthly), which tanks are included, which bacteriological indicators and methods to use, and how the results are documented and kept. This targeted guidance ensures the water remains free of indicators of contamination and meets health standards, with regular monitoring that supports prompt corrective actions if any issues arise. The other policies cover different areas or aspects of water systems and health services, but only CIM 6240.5 directly addresses the monthly bacteriological analyses of emergency potable water tanks.
