Which statement best describes Clean Water in Old Public Health incentives?

• A. Building new water reservoirs
• B. Encouraging bottled water consumption
• C. Protection of water supplies from sewage pollution and methods of water treatment, improving access to clean water
• D. Water usage restrictions during droughts

Answer: (C)

The key idea is safeguarding drinking water to prevent disease by controlling contamination at the source and ensuring proper treatment before it reaches people. Old public health efforts concentrated on keeping water supplies clean by protecting catchment areas from sewage pollution, building systems to separate waste, and implementing methods to treat water—like filtration and disinfection—so that everyone could access safe water. This approach directly reduces waterborne illness and supports population health.

That’s why the statement describing protection of water supplies from sewage pollution and water treatment, improving access to clean water, best fits. Building new reservoirs helps supply but doesn’t inherently address contamination issues; bottled water focuses on a private solution rather than public health infrastructure; drought restrictions aim at conserving water rather than ensuring safety and universal access.
