Florida CCR Requirements

Florida follows the federal July 1 delivery deadline for Consumer Confidence Reports, but adds a state-specific certification step: systems must submit a completed certification form to FL DEP by August 10 each year. The program runs under the Florida Department of Environmental Protection's Source and Drinking Water Program, which also oversees a drinking water landscape shaped by the state's dependence on groundwater aquifers and ongoing saltwater intrusion pressure along its coasts.

Who issues a CCR in Florida

The Florida Department of Environmental Protection (FL DEP), Source and Drinking Water Program, holds primacy for most Safe Drinking Water Act requirements in Florida. Its authority over public water systems derives from Chapter 403, Part VI of Florida Statutes and from the EPA delegation of primacy authority.

Florida had approximately 1,585 community water systems (CWS) as of 2024, according to FL DEP's 2024 Annual Compliance Report. Every one of those systems must produce an annual CCR. Not all public water systems must issue a CCR — the obligation applies specifically to community water systems, meaning systems that serve at least 15 service connections used by year-round residents or regularly serve at least 25 year-round residents.

Florida's CCR rule on top of the federal floor

The federal CCR rule lives at 40 CFR Part 141, Subpart O (§§ 141.151–141.156). Florida codifies its CCR requirements in Florida Administrative Code, Chapter 62-550, Rule 62-550.824 — Consumer Confidence Reports. Rule 62-550.824 adopts federal standards and supplements them with Florida-specific requirements.

Florida-specific additions include:

If there is any conflict between the federal floor and Florida's rule, you follow the stricter requirement.

The Florida CCR deadline

Florida operates on a two-deadline structure:

| Deadline | What it covers | Authority | |---|---|---| | July 1 | CCR must be delivered to all customers | 40 CFR § 141.155; F.A.C. 62-550.824 | | August 10 | Certification of Delivery form (FL DEP Form 62-555.900(19)) due to DEP district office | F.A.C. 62-550.824 |

Delivery by July 1 matches the federal deadline and means consumers must have the report in hand — by mail, electronic delivery, or another primacy-agency-approved method — on or before that date.

Certification by August 10 is Florida's state-level step. Systems must complete Form 62-555.900(19), the Certification of Delivery of Consumer Confidence Report, and submit it together with a copy of the CCR and any newspaper or posted notices to the applicable FL DEP district office. The form can be submitted by electronic mail.

This two-step structure is distinct from the federal certification timeline. Federally, the 2024 CCR rule revisions require systems to certify delivery within 10 days of distribution. Florida's August 10 date functions as a state-level annual compliance checkpoint rather than a rolling 10-day clock. If you are serving customers in Florida, the practical answer is: report in customers' hands by July 1, form at DEP by August 10.

For systems serving 500 or fewer persons, 40 CFR § 141.155(g)(2) provides a reduced-delivery option — systems may post notice in at least one location frequented by customers and notify them annually that the report is available on request, in lieu of direct mailing. This federal option flows through to Florida, subject to any district-level guidance.

For systems serving 10,000 or more persons, biannual delivery applies starting January 1, 2027. A second report covering the second half of 2026 would be due by December 31 under 40 CFR § 141.155(j)(2). Florida follows federal population thresholds; the state rule does not create different size cliffs.

PFAS in Florida CCRs

Federal requirements apply directly. Florida has not yet obtained primacy over PFAS requirements under the EPA's April 2024 PFAS National Primary Drinking Water Regulation. EPA Region 4 directly regulates PFAS monitoring for Florida public water systems under 40 CFR Part 141 as amended.

The April 2024 federal rule set individual MCLs for five PFAS compounds and one Hazard Index for a four-compound mixture:

| Regulated substance | Type | MCL | |---|---|---| | PFOA | Individual MCL | 4.0 ng/L (ppt) | | PFOS | Individual MCL | 4.0 ng/L (ppt) | | PFHxS | Individual MCL | 10 ng/L | | PFNA | Individual MCL | 10 ng/L | | HFPO-DA (GenX) | Individual MCL | 10 ng/L | | PFHxS + PFNA + HFPO-DA + PFBS mixture | Hazard Index | 1 (unitless) |

Initial monitoring must be completed by April 26, 2027. CCR reporting of PFAS results begins in 2027. Compliance with MCLs is enforceable beginning April 26, 2029.

Florida has a documented PFAS presence. FL DEP's PFAS Dynamic Plan (March 2022) identified contaminated public well systems in Stuart, Zephyrhills, and Escambia County, and established provisional groundwater cleanup target levels (P-GCTLs) of 70 ng/L for PFOA and PFOS — a remediation standard rather than a drinking water MCL, and one predating the far stricter 2024 federal rule. Florida utilities should treat the new federal 4 ng/L MCLs as the operative standard for CCR reporting.

For reporting requirements and what to include in your CCR for PFAS, see PFAS in your Consumer Confidence Report.

Source-water considerations: aquifers, saltwater intrusion, surface water

Florida's drinking water comes predominantly from groundwater. The state's primary aquifer systems — the Floridan Aquifer and the Biscayne Aquifer in South Florida — supply most community water systems. The Biscayne Aquifer provides roughly 98 percent of the public water supply for South Florida and is Miami-Dade County's primary drinking water source.

Coastal systems face saltwater intrusion pressure. Over-extraction from coastal aquifers, combined with rising sea levels, allows saltwater to advance into freshwater zones. In Miami-Dade County, chloride concentrations in some monitored aquifer sections have risen from around 250 mg/L in the late 1990s to roughly 600 mg/L by 2024. This is not a new problem, but the trajectory has accelerated. Saltwater intrusion can elevate sodium and chloride readings in source water, which affects CCR contaminant tables and can trigger state-required sodium language under F.A.C. 62-550.824.

Surface water is a secondary source for some inland and larger systems. Systems drawing from Lake Okeechobee or other surface water bodies face different contaminant profiles — particularly disinfection byproducts from chlorination of organically-rich source water.

For CCR purposes: your source water type determines which contaminant categories are most likely to show detectable results. FL DEP's Source Water Assessment Program (SWAP) produces assessments for each public water system that can inform how you frame source water discussions in your report.

What's changing in 2027 for Florida systems

The 2024 federal CCR rule revisions introduce several operational changes that Florida systems must track alongside the PFAS monitoring launch. The full picture is at What's changing in 2027 for CCRs. The short version for Florida utilities:

Biannual delivery (≥ 10,000 served). Starting January 1, 2027, systems at or above the 10,000-person threshold must distribute a second report by December 31 each year. 40 CFR § 141.155(j)(2). Florida follows this threshold; there is no state variation.

Mandatory summary section. Every CCR issued on or after January 1, 2027 must include a prominent summary at the beginning of the report, covering key health and compliance information. 40 CFR § 141.156, added by the May 2024 revisions.

PFAS reporting. Monitoring must be complete by April 26, 2027 and results reported in the 2027 CCR cycle. Because EPA Region 4 holds primacy for PFAS in Florida, coordinate directly with the regional office on monitoring schedules and reporting format.

LCRI compliance — November 1, 2027. The Lead and Copper Rule Improvements take effect November 1, 2027. Lead CCR disclosures must reflect the new action level of 0.010 mg/L (10 µg/L), down from 0.015 mg/L under the prior rule. Sampling protocol changes to paired first-and-fifth-liter samples; use the higher of the two values for compliance determination. 89 FR 86416 (Oct. 30, 2024).

Online posting (≥ 50,000 served). Systems serving 50,000 or more persons must post the current year's report on a publicly available website beginning January 1, 2027. 40 CFR § 141.155(f).
