What evaluates the ability of the installation to prevent contamination and service disruptions?

• A. Water Quality Test
• B. A Water Vulnerability Assessment (WVA)
• C. Sanitation Survey
• D. Environmental Impact Assessment

Answer: (B)

Assessing how well an installation can prevent contamination and maintain service centers on the resilience of the water system and its protective measures. A Water Vulnerability Assessment is designed to analyze where the system is most at risk—contamination pathways, critical components, redundancy, monitoring, and response capabilities—and to identify improvements that reduce the chance of contamination and outages. This broader look helps prioritize safeguards and readiness plans to keep water flowing safely during incidents.

A Water Quality Test, by contrast, measures the current condition of the water at a specific moment and doesn’t evaluate the system’s ability to prevent future contamination or outages. A Sanitation Survey focuses on sanitation facilities and practices rather than the integrity of the water supply itself. An Environmental Impact Assessment examines the broader environmental effects of a project, not the ongoing resilience of the installation’s water system to contamination or disruptions.
