PVNTMED responsibilities include evaluating which kind of samples?

• A. Food, drinking water, and wastewater samples
• B. Blood samples
• C. Soil samples
• D. Air samples

Answer: (A)

The main concept here is environmental health surveillance to prevent disease by evaluating the most direct exposure routes people have in a military setting. The best answer is the trio of food, drinking water, and wastewater samples. Food testing ensures safety from pathogens and contamination in the food supply used by personnel. Drinking water testing checks for water quality indicators and contaminants, ensuring potable, safe water in the distribution system. Wastewater testing monitors the effluent and treatment processes to prevent environmental release of pathogens or chemicals and to detect potential public health issues from wastewater streams. Blood samples fall under clinical diagnostics and medical care, not the environmental health focus of PVNTMED. Soil and air sampling are relevant to other public health or occupational health areas, but the core PVNTMED responsibility is evaluating food, drinking water, and wastewater samples to protect population health.
