Which item is NOT listed as a vulnerability?

• A. Solar panels on the roof
• B. Backflow prevention system
• C. Water distribution system
• D. Storage tank hatchways

Answer: (A)

Understanding vulnerabilities means looking at where the water system could be exposed to contamination or disruption. Backflow prevention systems are about stopping contaminated water from flowing back into the clean supply; if these devices are faulty or bypassed, they become a point of vulnerability. The water distribution system itself is a network that could be compromised at various points—pressure changes, tampering, or unprotected access can introduce risks. Storage tank hatchways are direct entry points to stored water, so unsecured hatchways are clearly potential vulnerabilities. Solar panels on the roof, on the other hand, are part of the facility’s energy supply and do not directly create a pathway for contaminating the water or interrupting its safety or delivery. They aren’t considered a vulnerability to the water system in this context.
