  "account": "On November 2, 2026, the Center Township water authority in Beaver County, 25 miles from Pittsburgh, issued a boil-water advisory following a routine E. coli test. The advisory remained in effect as officials continued to test the water, and students at Central Valley School District were sent home to learn remotely. The advisory was lifted on November 4. A single positive E. coli sample can disrupt daily life for a community, affecting everything from drinking water to dishwashing. E. coli is a common bacterium found in the digestive systems of people and animals, and its presence in drinking water indicates contamination by human or animal waste. Utilities routinely test water samples to catch contamination early. When E. coli is detected, it means the water may contain harmful bacteria, viruses, or parasites. Boiling water kills harmful bacteria, protozoa, and inactivates viruses. Water utilities must address the contamination, fix the issue, and conduct further testing to ensure no more positive samples are found before lifting the advisory. Schools, being particularly vulnerable, may need to close or switch to virtual learning during a boil-water advisory to ensure the safety of children.",
  "summary": "A boil-water advisory in Beaver County has residents and schools adjusting. Water researchers explain what E. coli in tap water means and how utilities make it safe.",
