Board approves monthly sampling at three Wellfleet beaches

The Wellfleet Board of Health voted to change routine bacterial sampling at three town beaches — Cahoon Hollow, Duck Harbor and The Gut — from weekly to monthly sampling following a county presentation showing prolonged low bacterial detections.

Jenny, the county bathing-beach program coordinator from Barnes Buchanan Health and Environment, told the board that none of the three beaches "got anywhere near" the state's single-sample threshold in recent seasons and that long-term data support reinstating their variant (monthly) sampling status. "None of these beaches got anywhere near that really in the past 3 years," she said, noting the program's detection limit is 10 MPN and citing the state single-sample threshold as "a 104 MPN."

The motion to change sampling frequency was made by the meeting chair (Speaker 2) following the presentation; the transcript does not record a clearly identified seconder. The chair called a roll call and the board voiced assent and approved the motion. Staff and the county presenter discussed procedural steps for filing or signing the variance application after the vote.

Why it matters: monthly (variant) sampling reduces the number of samples the county must collect and lab-analyze and reflects a regulatory allowance when long-term data show consistently low bacterial levels. The county presenter said the three beaches meet variance criteria based on consecutive bathing seasons without exceedances, though she noted a small number of historical exceedances (Duck Harbor had an exceedance in 2023).

The board did not detail a timeline for when the change will take effect; staff said signature and filing logistics remain to be completed.
