On December 7, 2023, the Mississippi State Department of Health imposed a Boil-Water Alert on the City of Oxford water system after E. coli was detected in a routine sample, affecting approximately 14,650 Oxford Utilities customers and parts of the University of Mississippi campus that draw on the Oxford supply. The University extended the precaution across the main Ole Miss water supply (~20,000 users) 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; Oxford Utilities later determined the original positive sample was contaminated by human error during collection.

Oxford Eagle — boil water notice lifted, paraphrased into RebAlert formatTo check this alert, Claude (an AI) read it in full 25 separate times, independently. Each read decided whether the message answers each of the six questions and gave a short reason. A final reviewer then weighed all 25 and wrote the plain-English verdict you see when you open a row. The score (for example 22/25) is how many reads agreed; the 25 individual reads are tucked underneath if you want to check them.
REBALERT: A Boil Water Alert has been issued for select campus buildings. See http://emergency.olemiss.edu for more info.
Final assessment
Unanimous: signed with the branded 'REBALERT' signature identifying the Ole Miss alert system.
Who is sending the alert and who is responding. People act faster on a message from a clearly identifiable, credible sender, such as a named department, the police, or a branded alert system, than on an anonymous notice. A branded signature counts.
Final assessment
Unanimous: 'Boil Water Alert' names the specific water-contamination hazard.
What the threat actually is. A complete warning names the specific danger, such as a shooter, a fire, a tornado, or a gas leak, rather than a vague emergency, because people decide what to do based on what they are facing.
Final assessment
Unanimous: 'select campus buildings' gives a general but specific location scope.
Where the threat is. Saying whether danger is in a specific building, a part of campus, or area-wide lets people judge their own proximity and choose a safe direction. Without a where, a warning is hard to act on precisely.
Final assessment
Unanimous: the message only directs readers to a link for more information, giving no explicit protective instruction like boiling water before use.
The protective action to take. A clear, specific instruction, such as shelter in place, evacuate, avoid the area, or run-hide-fight, drives faster and more correct protective behavior than describing the threat alone.
Final assessment
Unanimous: no clock time, date, or recency marker is given anywhere in the message.
When the message applies. A timestamp, the word now or immediately, or a phrase like until further notice tells the reader whether the danger is current and how quickly to act.
Final assessment
Unanimous: no statement of health consequence or harm from the water issue is included.
What the hazard could do to the people in its path. Beyond naming the threat, a complete warning conveys its potential consequences or severity, such as that a tornado can level buildings or that a leak could be explosive, so recipients grasp how much danger they are in. Research on warning message content finds that a concrete impact statement helps people personalize their risk and act sooner.
