Which action most reduces risk to water sources during emergencies?

• A. Expand industrial activity near water sources
• B. Restore all wetlands immediately
• C. Implement source protection and barriers to prevent contamination
• D. Rely solely on bottled water distribution

Answer: (C)

Protecting water sources at their origin during emergencies is the most effective way to reduce risk. When you shield intakes and watershed areas from contamination, pollutants are kept out before they can enter the supply, lowering health risks and the amount of treatment and emergency response needed. Implementing source protection and barriers means putting in place physical and management safeguards—like securing upstream land use, restricting access around critical points, establishing protective buffer zones, and having ready containment measures—that prevent contaminants from reaching the water supply.

Other approaches don’t address the root of the problem. Expanding industrial activity near water sources adds risk and can increase potential spills. Rushing to restore wetlands, while beneficial in the long term, won’t guarantee immediate protection in an ongoing emergency. Relying solely on bottled water shifts the challenge to logistics and does not reduce contamination at the source. By focusing on protecting the source, you reduce the likelihood of contamination entering the system from the start.
