Residents of Center Township in Beaver County, Pennsylvania, were under a boil-water advisory from Nov. 2 to Nov. 4, 2026, following the detection of E. coli in a routine water sample. The Center Township Water Authority issued the notice after a sample taken from Wilhelm Drive tested positive for the bacteria.
While the initial sample indicated contamination, four other samples collected on the same day returned negative results for both E. coli and coliform bacteria. A follow-up test at the original site was negative for E. coli but remained positive for coliforms, according to the utility.
During the advisory, the Center Township Water Authority instructed residents to boil water for one minute and allow it to cool before using it for drinking, cooking, brushing teeth, making ice, or washing dishes. As a precautionary measure, the Central Valley School District transitioned students to remote learning for Nov. 3 and Nov. 4.
The utility maintained the advisory until testing confirmed the safety of the water supply. The authority stated that the advisory would remain in effect until two consecutive days of testing showed no presence of coliforms. Following these results, the advisory was officially lifted.
