Boca Raton's no-swim and no-irrigation advisory remained posted Tuesday after the city said a failed connection on a 16-inch wastewater pipe allowed wastewater to enter storm drains leading to the Intracoastal Waterway.

In a September 19 update distributed through the city's verified Nextdoor account, the City of Boca Raton said bacteria levels in the latest water-quality testing had decreased but were not yet low enough for the advisory to be lifted. Drinking water was not affected.

Residents should wait for a formal update from the City of Boca Raton or the Florida Department of Health before assuming the restrictions have ended. The advisory remained posted on the city's website as of September 22, but MyWestBoca.com is using that careful formulation because no agency directly confirmed that the advisory remains legally or operationally in effect.

What Caused the Spill

According to the City of Boca Raton's September 19 update, the failure involved a connection on a 16-inch wastewater pipe. The failure occurred west of the hotel entrance near the Camino Real bridge.

The city said the failed connection caused wastewater to leak from the pipe. Some of that wastewater entered storm drains on the north side of Camino Real, and those storm drains discharge into the Intracoastal Waterway.

The Florida Department of Health in Palm Beach County issued its original health alert on September 18, 2026. The affected water connects to the Intracoastal Waterway just northwest of the Boca Raton Resort, and the City of Boca Raton's notice expressly includes Lake Boca among the waterways for which precautions should be taken.

The advisory applies to residents and visitors near the identified waterways. It does not extend to all Boca Raton beaches, all city waterways, the Atlantic Ocean or the entirety of the Intracoastal Waterway.

What Testing Found

The City of Boca Raton reported that bacteria levels in the latest water-quality testing had decreased. However, those levels remained too high to lift the advisory as of the September 19 update, and the no-swim and no-irrigation advisory therefore remained in place for the affected waterways at that time.

The city's public update provided a qualitative testing update but did not include numerical bacterial measurements or complete laboratory reports in the material reviewed. No numerical bacterial measurements or complete laboratory results were included in the city's public update.

The city continued coordinating testing and cleanup with the Florida Department of Environmental Protection and health officials. The water should not be considered safe until officials issue a formal all-clear.

What Residents Were Instructed Not to Do

Officials issued a health alert, a no-swim advisory and a no-irrigation advisory. Residents and visitors near the affected waterways were advised to avoid swimming and unnecessary water contact, and not to draw irrigation water from the affected waterways. Anyone coming into contact with the affected water was advised to wash thoroughly, especially before eating or drinking.

What Officials Said About the Health Concern

The health department described the concern as possible bacterial contamination. According to the department, water with high levels of fecal bacteria can cause disease, infections or rashes. Children, older adults and immunocompromised people may be at risk even at lower bacterial concentrations and were advised to avoid exposure.

Recreational Water vs. Drinking Water

Drinking water is not affected, according to health and city officials. The advisory applies only to recreational contact with the identified surface waterways. Residents do not need to take precautions regarding tap water as a result of this incident.

What Remains Unanswered

The public notices and the city's September 19 update do not specify the total volume of wastewater released, the exact duration of the leak, whether the failed connection received a permanent repair, the numerical bacterial measurements, the geographic sampling locations, or when officials expect to lift the advisory. MyWestBoca.com is not speculating about any of these points.

How Residents Can Obtain Additional Information

For questions about health effects from wastewater exposure, the Florida Department of Health provided the following contact information: the main number 561-837-5900, email CHD50ContactUs@FLHealth.gov, an after-hours number 561-881-1888, and the Public Information Office at 561-671-4013. Residents can also monitor the City of Boca Raton homepage, advisory page and Alert Center for updates.

This article should be updated immediately if officials issue an all-clear. Wait for an official update from the city or health department before resuming swimming or irrigation-water use.

This advisory concerns a frequently visited local recreational waterway. Many West Boca residents boat, paddle, swim or fish in the Lake Boca and Intracoastal area, and some may use boats launched or stored elsewhere in Boca Raton. The spill did not occur in West Boca, but the practical relevance for residents who recreate in eastern Boca Raton is clear.
