Answer to Question 1

B, C, D
Water can be rendered safe for drinking by boiling, treating with household bleach, or removing from hot water heaters or commode tanks. Allowing water to sit for 24 hours or pouring water through layers of cotton towels does not adequately render the water safe to drink.

Answer to Question 2

A, B, C, D, E
Civil defense courses should explain the role of all of these participants.
