Under what circumstance does a water utility need to issue immediate public notification regarding a water quality issue?

• A. If there's detectable concentration of iron and manganese
• B. If there is potential for human health to be immediately impacted
• C. If sulfate exceeds 20 mg/L
• D. If TDS exceeds 50 mg/L

Answer: (B)

The need for immediate public notification regarding a water quality issue primarily arises when there is a potential for human health to be immediately impacted. This means that if a situation arises where there is a significant risk that the water might cause illness or adverse health effects upon consumption, the utility must act quickly to inform the public. This is crucial because providing timely information allows consumers to take necessary precautions, such as boiling water or using bottled water, until the issue is resolved. In comparison, while the presence of detectable levels of substances like iron and manganese, sulfate, or total dissolved solids (TDS) can affect water quality and taste, these factors do not present an immediate health risk unless they are at unusually high levels or accompanied by other hazardous substances. Thus, they do not trigger the same urgent need for public notification as a direct threat to health does.
