E. coli (Escherichia coli) violations in Florida
1,676 active public water systems in Florida had a E. coli (Escherichia coli) violation in the past three years, 239 of them in the latest quarter of EPA's data. What E. coli (Escherichia coli) is and why it matters.
Health effects: Most E. coli strains cause diarrheal illness. Some strains (e.g., O157:H7) produce toxins causing severe bloody diarrhea, hemolytic uremic syndrome (HUS — a form of kidney failure), and death — especially in children under 5 and the elderly. Even non-pathogenic strains in drinking water indicate that disease-causing organisms may also be present.

About this data
A system is counted once if any of its violations in the past three years involved E. coli (Escherichia coli), including monitoring and reporting lapses. Rules violated and status in the table are for the whole system, not E. coli (Escherichia coli) alone.
Source: the U.S. EPA's Enforcement and Compliance History Online system (ECHO), which publishes the federal Safe Drinking Water Information System. EPA's terms and values are shown as published. The Florida records are from EPA's data refresh of Oct 7, 2026; EPA refreshes this data quarterly, and states report to EPA with a lag of three to six months, so the newest violations may not appear yet.
