What are potential health risks of drinking water from local sources during shortages?

• A. Hepatitis
• B. Intestinal parasites
• C. Industrial toxins
• D. Hepatitis, intestinal parasites, and industrial toxins

Answer: (D)

During shortages, local water sources are more likely to be inadequately treated or contaminated, so a range of hazards can be present. Viral infections such as hepatitis can spread through water contaminated with fecal matter, making waterborne hepatitis a real risk. Intestinal parasites, including Giardia and Cryptosporidium, can survive in untreated or poorly treated water and cause gastrointestinal illness. Industrial toxins from nearby factories or runoff—heavy metals, solvents, and other chemicals—can leach into water supplies, especially when monitoring and treatment are strained. Because a compromised water supply can harbor biological contaminants as well as chemical ones, all three types of risks—hepatitis, intestinal parasites, and industrial toxins—can be present. That’s why this option is the best, as it reflects the full range of hazards that might be encountered. If you only consider one type, you’d miss the other potential dangers that can accompany shortages, which is why the comprehensive answer best fits the scenario. In practice, approaches to reduce risk include treating or boiling water, using bottled water when available, and avoiding sources that appear questionable until the supply is assured.
