Which item is listed as a vulnerability related to safeguarding the water system?

• A. Backflow prevention system
• B. Online dashboards
• C. Customer surveys
• D. Public notices

Answer: (A)

Safeguarding the water system hinges on preventing contaminants from entering the distribution network, especially through backflow from consumer piping. A backflow prevention system directly targets this risk by stopping reverse flow when there’s a pressure difference, such as backpressure or back-siphonage. By installing and maintaining proper backflow prevention, you remove a major vulnerability that could allow contaminants to enter the supply. The other items are monitoring or communication tools, not protections against this physical risk, so they don’t address the vulnerability in the same way.
