What is a Consumer Confidence Report?

A Consumer Confidence Report (CCR) is the annual drinking water quality report that community water systems must provide to the people they serve. It lists the contaminants detected in the system’s water during the year, where the water comes from, and how the results compare with federal limits. EPA’s revised CCR rule takes effect January 1, 2027, and the first reports in the new format are due July 1, 2027.

MAYO CORRECTIONAL INSTITUTION Water System

Consumer Confidence Report status

MAYO CORRECTIONAL INSTITUTION must publish a Consumer Confidence Report — the annual drinking water quality report covering calendar year 2026 — by July 1, 2027.

As of August 1, 2026, EPA's federal records show 2 items for MAYO CORRECTIONAL INSTITUTION that are open and awaiting resolution. None are health-based violations — open items of this kind are most often monitoring or reporting requirements, not water-safety findings.

Data sourced from the EPA ECHO database (SDWA bulk download), last refreshed August 1, 2026. This is a record-keeping and public-information tool — it does not replace Florida’s official records. Always confirm current status with Florida before making decisions based on this information.

System facts

System ID (PWSID): FL2341182
System type: Community Water System
Population served: 1,400
Service connections: 40
Ownership: state government
Water source: groundwater (wells)

MAYO CORRECTIONAL INSTITUTION is one of 925 community water systems in Florida in the 501 to 3,300 people size category, serving 1,400 people from groundwater.

As of August 1, 2026, its federal record holds 102 entries between 2002 and 2025, of which 2 remain open; none are health-based.

Of the 102, 62 are monitoring and reporting requirements — the category that accounts for about four in five of all violations in EPA's national dataset — rather than findings about the water itself. The record involves the Stage 1 Disinfectants and Disinfection Byproducts Rule, the Stage 2 Disinfectants and Disinfection Byproducts Rule, and the Total Coliform Rules.

Common questions

Is MAYO CORRECTIONAL INSTITUTION required to publish a Consumer Confidence Report?: Yes. MAYO CORRECTIONAL INSTITUTION is a community water system, and federal rules (40 CFR 141 Subpart O) require every community water system to publish a Consumer Confidence Report each year.
When is MAYO CORRECTIONAL INSTITUTION’s next Consumer Confidence Report due?: MAYO CORRECTIONAL INSTITUTION’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.
Does MAYO CORRECTIONAL INSTITUTION have any open drinking water violations on record?: As of August 1, 2026, EPA's federal records show 2 items for MAYO CORRECTIONAL INSTITUTION that are open and awaiting resolution. None are health-based violations — open items of this kind are most often monitoring or reporting requirements, not water-safety findings.
What is a Consumer Confidence Report?: A Consumer Confidence Report (CCR) is the annual drinking water quality report that community water systems must provide to the people they serve. It lists the contaminants detected in the system’s water during the year, where the water comes from, and how the results compare with federal limits. EPA’s revised CCR rule takes effect January 1, 2027, and the first reports in the new format are due July 1, 2027.
