UPDATE: Follow-Up Raw Water Well Samples
Test Negative for E. coli
Naples, FL (June 27, 2026) – The City of Naples notified water customers yesterday that one of its raw water wells tested positive for E. coli bacteria on Thursday, June 25, 2026. We are pleased to report that the five follow-up samples collected from the affected raw water well within 24 hours of the initial positive sample, as required by the Florida Department of Environmental Protection (FDEP) permit, returned absent (tested negative) of E. coli bacteria. Customers do not need to boil their water. The City’s drinking water remains safe to drink and use.
The City immediately discontinued use of the affected raw water well and has relied on the City’s remaining 50 wells to meet demand. Additionally, the City increased sampling at its water sources to determine the source of the contamination. As required by FDEP before returning the well to service, the City will disinfect the well and complete a satisfactory ten-sample well survey.
To help our customers better understand the City’s water treatment process, raw water or untreated groundwater is collected from the City’s well sites and transported to the Water Treatment Plant. There, it undergoes a rigorous treatment and disinfection process to meet all state and federal drinking water standards before it is distributed to customers. Finished drinking water is routinely tested prior to distribution, and all finished water samples collected have met all regulatory standards.
We apologize for any inconvenience and appreciate your patience and understanding as the City follows the FDEP regulatory requirements to ensure the continued safety and reliability of our drinking water system. As always, you may contact our Water Treatment Plant at (239) 213-3004 or reply to this email with any comments or questions.
This information is being sent to water customers who have provided their email address and subscribed to email communications. Please feel free to share this information with others who drink City of Naples water, especially those who may not have received this notice directly (for example, people in apartments, nursing homes, schools, and businesses). You can do this by posting this notice in a public place, distributing copies by hand or mail, or forwarding this email.
