Florida SB 700 (Florida Farm Bill) bans adding fluoride to public water statewide (effective July 1, 2025); systems no longer add it. CDC's listing predates the ban. Naturally occurring fluoride is unaffected.
Per CDC My Water's Fluoride · See details below
Risk classification follows EPA's published values for safe drinking water, with caution and concern bands reviewed by a clinician. Past resolved violations do not influence this card. See methodology.
Lead service line inventory
Utility reports no confirmed lead service lines
MAYO CORRECTIONAL INSTITUTION reports 0 confirmed lead service lines, 78 non-lead, 0 unknown (total 78) in the EPA SDWIS service line inventory (2026Q1).
- 0 confirmed lead service lines
- 0 galvanized requiring replacement (LCRI treats these as lead)
- 0 unknown (0.0% of total)
- 78 confirmed non-lead (100.0%)
- 78 total service lines in the system
What to do if your service line might be lead
- Ask your utility to check the service-line classification for your specific address. Many utilities provide a public address-lookup tool linked from the inventory page.
- Get on the replacement queue. Under the LCRI, utilities must replace all lead and galvanized-requiring- replacement lines within 10 years (clock generally starts November 2027). Some prioritize requests.
- Until the line is replaced: flush the tap 30 seconds after long stagnation, use cold water for drinking and cooking, and consider an NSF/ANSI 53 lead-rated tap filter.
- Talk to your clinician about a blood lead test for anyone in the home, especially a pregnant person or a child under 6. Lead in drinking water guide.

Lead and copper test results
The most recent measurement per contaminant from EPA's Lead and Copper Rule sampling.
Why only lead and copper, and not arsenic, nitrate, or others?
EPA's bulk SDWIS download is the only nationwide per-system sample data they publish, and it only includes the Lead and Copper Rule table. Values for other regulated contaminants (TTHMs, nitrate, arsenic, etc.) appear on this page only when they trigger a violation. For the full per-system contaminant suite, see the utility's annual Consumer Confidence Report (link further down the page).
| Contaminant | Most recent | Date | Risk |
|---|---|---|---|
| PB90 | 0.0019 mg/L | December 1, 2024 | Caution |

Fluoride
Florida no longer adds fluoride to public water
Under Florida SB 700 (Florida Farm Bill), effective July 1, 2025, public water systems in Florida may not add fluoride to drinking water. Systems that previously adjusted fluoride have stopped. The CDC figures on this page are historical and describe fluoridation before the ban; naturally occurring fluoride in source water is unaffected.
Per CDC My Water's Fluoride (pre-ban)
MAYO CORRECTIONAL INSTITUTION does not add fluoride; Florida bans adding fluoride to public water statewide.
Under Florida SB 700 (Florida Farm Bill), effective July 1, 2025, no public water system in Florida may add fluoride. CDC's My Water's Fluoride listing below predates the ban and has not been updated for it. Naturally occurring fluoride in the source water is unaffected; the utility's annual water quality report has the latest measured concentration.

Compliance history
EPA-recorded violations against this system over the last 5 years.
How to read this section
Health-based violations are when a measured limit was exceeded; the measured concentration is shown alongside the EPA federal limit where SDWIS published it. Monitoring and reporting items are paperwork issues (missed sample dates, late filings) that do not themselves indicate unsafe water.
No health-based violations
No health-based violations on file in the last 5 years. EPA recorded 22 monitoring or reporting items (paperwork) during the same period.

Where to see every contaminant this utility tested for
EPA's bulk SDWIS dataset gives MyTapWater.us per-system measured values for lead and copper, plus violation records for everything else. To see every regulated contaminant this utility tested for in the past year (TTHMs, HAA5, nitrate, arsenic, fluoride, chromium, etc.) with measured values, read the utility's Consumer Confidence Report (CCR).
Every community water system is required by EPA to publish a CCR annually, by July 1, listing every contaminant they sampled, the measured value, the federal limit, and any health-based exceedances. Most utilities post the report online; some mail it with your bill.
How to find MAYO CORRECTIONAL INSTITUTION's CCR:
- Search the web for "MAYO CORRECTIONAL INSTITUTION consumer confidence report" . The PDF is usually on the utility's own website.
- Or call the utility directly. Their phone number is in the contact section below.
