Wastewater analysis on Nantucket, the upscale summer retreat off Cape Cod, has uncovered startling levels of cocaine—about 50% higher than the national average. The Surfside Wastewater Treatment Facility, which serves approximately three-quarters of the island’s residences, led the testing initiative to track drug trends discreetly and without identifying individuals or neighborhoods. Officials noted that while cocaine levels spiked, levels of fentanyl—a powerful synthetic opioid—remained below national norms.
This testing program was launched earlier this summer as part of a broader effort to monitor community health through non-invasive means. Though the island maintains an exclusive reputation, local authorities emphasize that the wastewater data offers a broad glimpse into public usage patterns rather than a judgment on individual behavior.
