The University extended the precaution across the [main Ole Miss water supply (~20,000 users)](https://thedmonline.com/oxford-parts-of-um-campus-under-boil-water-notice/) including Campus Walk, the South Campus Recreation Center, the South Oxford Center, the Jackson Avenue Center, Rowan Oak, the University Museum, the Music Building, the Ford Center, the Ole Miss Golf Course, and the University-Oxford Airport. Re-samples taken December 7 and 8 came back clean and the alert was [lifted at noon on December 9, 2023](https://www.oxfordeagle.com/2023/12/09/boil-water-notice-lifted/); Oxford Utilities later determined the original positive sample was contaminated by human error during collection.",
    "outcome": "Boil-water alert lifted at 12:00 PM CST on December 9, 2023 after MSDH labs confirmed two consecutive clean samples. No documented illnesses were attributed to the water. Oxford Utilities concluded the original positive sample had been contaminated by human error during sample collection rather than reflecting actual contamination of the distribution system."

  "context": "On December 7, 2023, the [Mississippi State Department of Health (MSDH) Bureau of Public Water Supply imposed a state Boil-Water Alert on the City of Oxford water system](https://oxfordeagle.com/2023/12/07/oxford-under-boil-water-alert-14650-customers-affected/) after E. coli was detected in a routine sample collected by Oxford Utilities. The alert covered approximately 14,650 Oxford Utilities customers and, because the [University of Mississippi's main campus uses the Oxford water supply for many facilities](https://thedmonline.com/oxford-parts-of-um-campus-under-boil-water-notice/), it cascaded onto the Ole Miss campus the same day. Affected campus locations included Campus Walk, the South Campus Recreation Center, the South Oxford Center, the Jackson Avenue Center, Rowan Oak, the University Museum, the Carriage House, Brandt Memory House, Walton-Young House, the Music Building, the Ford Center, the Ole Miss Golf Course, the University-Oxford Depot, and the University-Oxford Airport. Oxford Utilities and MSDH collected re-samples on December 7 and 8; both came back clean, and the alert was [lifted at 12:00 PM on December 9, 2023](https://www.oxfordeagle.com/2023/12/09/boil-water-notice-lifted/). Oxford Utilities subsequently announced that the [original positive sample had been contaminated by human error during collection](https://www.thelocalvoice.net/oxford/mississippi-state-department-of-health-lifts-boil-water-alert-for-the-city-of-oxford-water-supply/) rather than reflecting actual E. coli in the distribution system. The case is significant for the campus alert archive because it documents a 48-hour advisory-category alert at a flagship public university timed to the start of finals, illustrates the campus-side consequences of a city water utility's sampling protocol, and contextualizes Mississippi's broader water-infrastructure pattern alongside the [2022 Jackson water crisis](https://en.wikipedia.org/wiki/Jackson,_Mississippi_water_crisis).",
  "keyFindings": [
    "MSDH issued the boil-water alert on December 7, 2023 after E. coli was detected in a routine sample",
    "Approximately 14,650 Oxford Utilities customers and parts of the Ole Miss campus served by the Oxford supply were under the advisory; the broader Ole Miss water system serves about 20,000 users",
    "The advisory was lifted at 12:00 PM CST on December 9, 2023 after two consecutive clean re-samples",
    "Oxford Utilities subsequently determined the original positive sample had been contaminated by human error during sample collection rather than reflecting actual contamination",
    "Advisory-category alerts use email rather than SMS, reflecting lower urgency but broader informational needs"
