What is required regarding water provision for laboratory animals?

• A. Water devices require daily checks.
• B. Water should be potable and uncontaminated.
• C. Water should be provided only on protocol days.
• D. Water can be non-potable.

Answer: (B)

Water quality is fundamental to the wellbeing of laboratory animals and the integrity of experimental data. Water provided should be potable and uncontaminated, meaning it is safe for drinking and free from harmful chemicals, microbes, and particulates. When water is potable and uncontaminated, animals stay healthy, dehydration-related issues are avoided, and data aren’t confounded by infections or contaminants that could alter physiology or responses to treatments. In practice, facilities monitor water systems and perform routine quality checks to ensure continuous access to clean water, but the core requirement is that the water itself must be safe to drink. Providing non-potable water or restricting access to only protocol days would jeopardize animal welfare and experimental validity. Regular checks of water devices are important for reliability, but they do not override the requirement for potable, uncontaminated water.
