**BLUE FLAG BEACH. RED FLAG QUESTIONS.**
Port Burwell Municipal East Beach has experienced repeated adverse E. coli results this summer.
Southwestern Public Health confirmed to PBVA that the last three reported geometric means increased from approximately 338 → 461 → 900 CFU/100 mL. Ontario’s swimming-advisory threshold for the geometric mean is 200 CFU/100 mL.
In the most recent sampling round, SWPH advised that four of the five individual samples were reported as greater than 1,000 CFU/100 mL, with the fifth at 620.
PBVA also confirmed that Port Burwell Provincial Park staff collect the water samples for both the Provincial Park beach and Bayham’s Municipal East Beach.
That makes what happened this past week especially relevant.
The Provincial Park received an adverse result and posted a clear “Beach unsafe for swimming” notice on August 13. The Park then resampled. **By August 14 — the next day — it had received an updated result and publicly advised that its beach was once again safe for swimming.**
Bayham, by contrast, considered additional sampling and decided not to resample the Municipal East Beach.
That real-world comparison matters because, at Bayham’s August 10 Waterfront Advisory Committee meeting, follow-up sampling was framed largely in terms of cost and turnaround time.
Today, August 16, the Municipal East Beach remains posted with Southwestern Public Health warning signs and the Blue Flag is not flying. The RED water-quality flag itself has been removed.
The RED flag is the signal regular beach users have learned to look for. **Removing it while the official SWPH advisory remains RED is perplexing and risks sending mixed messages to beachgoers.**
The attached photographs and screenshots show why timely communication matters.
During the August 10 WAC discussion, attention also shifted to the observation that people continued swimming despite the RED advisory. Members were told that parking transactions were up about 2.5%.
But Bayham’s own mid-year report shows that parking comparison covered only May 1 to June 30 — before the repeated adverse water-quality results in July and August. No July or August-to-date parking transaction data were presented to WAC, nor was there an analysis comparing parking activity with weather conditions and RED advisory periods.
**The parking information presented therefore could not establish that adverse water quality was having little or no effect on beach use.**
And if people were continuing to enter the water despite a RED advisory, that should have strengthened the case for timely follow-up sampling, public education and clear communication.
Perhaps most concerning, nobody in municipal leadership brought the discussion back to WAC’s written role as Bayham’s Blue Flag Beach Management Committee.
The neighbouring Provincial Park showed that follow-up testing could provide useful information to the public by the very next day.
**Bayham considered resampling and chose not to do it. Given the repeated adverse results, that decision deserves a clear explanation.**
That is exactly the kind of issue Bayham’s Blue Flag Beach Management Committee should be examining: timely testing, public education, clear communication, and whether beach users are being given the information they need to make informed decisions.
