Texas CCR Requirements

Texas water systems produce Consumer Confidence Reports under the same federal framework as every other state, but the Texas Commission on Environmental Quality (TCEQ) adds an important operational layer: wholesale water providers must deliver source data to their retail systems by April 1 each year, well before the July 1 customer distribution deadline. Understanding both the federal floor and Texas's own wholesale-provider rules is where most compliance questions arise.

Who issues a CCR in Texas

TCEQ is the primacy agency for the Safe Drinking Water Act in Texas. It sets state-level implementation rules, reviews CCR certifications, and provides templates and guidance through its Drinking Water Viewer portal at dwv.tceq.texas.gov.

Texas has roughly 7,200 public water systems total, of which a substantial share are community water systems (CWS) — the only type required to produce a CCR each year. (Texas 2023 Annual Compliance Report) That population ranges from large municipal utilities serving hundreds of thousands to small rural systems with just a few hundred connections. The rules that apply to a given system turn on how many people it serves, though the core CCR content requirements apply to all.

Texas's CCR rule on top of the federal floor

The federal CCR rule sits at 40 CFR Part 141, Subpart O, §§ 141.151–141.156. Texas codifies its CCR requirements at 30 Texas Administrative Code (TAC) Chapter 290, Subchapter H: Consumer Confidence Reports, primarily at §§ 290.272 through 290.274. (30 TAC §290.272)

Texas adopts the federal requirements with some additions. The key state-layer provisions are:

Wholesale provider data flow

This is the Texas-specific operational detail that catches retail systems off guard. Many Texas community water systems purchase treated water from a wholesale provider rather than treating their own source water. But the retail system — the one that sends bills to customers — is responsible for distributing the CCR. To do that, the retail system needs the wholesale provider's water quality data.

TCEQ addresses this with an explicit data-delivery requirement under 30 TAC §290.274(g): wholesale water systems must deliver all required CCR-relevant monitoring and compliance data to every consecutive (retail) community water system they supply by April 1 of each year. That April 1 date gives retail systems three months to compile their own data, prepare the full CCR, and meet the July 1 distribution deadline.

What the wholesale provider must supply includes:

Nitrate and nitrite data are excluded from the wholesale obligation because every system is required to collect its own samples for those parameters.

Wholesale systems certify their delivery to TCEQ by May 1 using TCEQ's combined Certificate of Delivery form — the same form used for retail systems. A single certificate covers delivery to multiple purchasing systems.

If you operate a retail system that receives water from a wholesale provider and that provider misses the April 1 deadline, flag it immediately with TCEQ. Your July 1 deadline does not move, so a late supplier creates real compliance risk.

TCEQ certification and Drinking Water Viewer

Every Texas community water system must certify CCR delivery to TCEQ using the CCR Certificate of Delivery form. Submit the completed form by email to PWSCCR@tceq.texas.gov. (TCEQ CCR page)

The federal rule tightened the certification window in 2024: systems must certify within 10 days of completing distribution (40 CFR § 141.155), down from the previous three-month window. The operational sequence for most Texas systems is: distribute by July 1, certify within 10 days.

Drinking Water Viewer (DWV) is TCEQ's public-facing portal for Texas water system data. It replaced the older Drinking Water Watch system. Systems use DWV to download their annual CCR template pre-populated with monitoring data, and members of the public can use it to look up any Texas system's monitoring results, schedules, and violations. Access it at dwv.tceq.texas.gov.

TCEQ also provides a CCR template generator through DWV that auto-inserts required health-effects language and formats the contaminant tables. Most Texas systems use this template as their starting point, customizing sections for system-specific narrative and any exceedances.

Texas-specific contaminants and considerations

Arsenic. Arsenic occurs naturally in Texas groundwater, particularly in West Texas and the Trans-Pecos region. A 2024 assessment by the Bureau of Economic Geology documented samples from more than 9,000 groundwater wells in Texas, finding arsenic concentrations exceeding the federal MCL of 10 µg/L in data points associated with water systems serving roughly 81,000 people. (UT Bureau of Economic Geology, 2024) If your system's CCR reports arsenic results, the CCR must include the required health-effects language under 40 CFR § 141.154. TCEQ's template generator flags when §290.273 secondary MCL language must also be added.

Fluoride. Texas groundwater in some regions contains naturally elevated fluoride. Systems with fluoride detections above the secondary MCL (2 mg/L) include the advisory language in the CCR. The primary MCL is 4 mg/L.

Lead. Lead in Texas drinking water is primarily a distribution system issue — lead service lines and lead-containing fittings in older housing stock — rather than a source-water issue. Your CCR must include the federally mandated lead educational language (40 CFR § 141.154) and, beginning with reports covering 2024 data, a statement about your lead service line inventory with instructions for customers to access the publicly available inventory (40 CFR § 141.153(h)(8)). See Lead and your CCR for how LCRI changes lead disclosure requirements starting November 1, 2027.

PFAS. Texas does not have state-level PFAS MCLs. The governing standards are the federal PFAS National Primary Drinking Water Regulation, finalized April 2024. Texas systems implement those standards through TCEQ; there are no additional Texas-specific PFAS limits. Initial monitoring under the federal rule must be completed by April 26, 2027, with PFAS results appearing in CCRs that cover 2027 data.

Deadlines and delivery

The standard Texas CCR calendar runs as follows:

| Date | Obligation | |---|---| | April 1 | Wholesale providers deliver water quality data to retail systems (30 TAC §290.274(g)) | | May 1 | Wholesale providers certify delivery to TCEQ | | July 1 | All CWS distribute CCR to customers (30 TAC §290.274(a)) | | Within 10 days of distribution | All CWS certify delivery to TCEQ via Certificate of Delivery | | December 31 | Second CCR due for systems serving ≥ 10,000 (beginning with 2027 compliance year) |

The biannual delivery requirement — two CCRs per year for systems serving 10,000 or more people — takes effect for the 2027 compliance year under 40 CFR § 141.155(j)(2). The first report covers the first half of the year and is due July 1; the second covers the full year and is due December 31.

What's changing in 2027 for Texas systems

The 2027 compliance year brings more simultaneous changes than any year since the CCR rule was first issued in 1998. Texas systems should plan now rather than in early 2027. Full context is at What's changing in 2027.

LCRI compliance — November 1, 2027. The Lead and Copper Rule Improvements (LCRI), finalized October 2024, set a compliance date of November 1, 2027. The action level for lead drops from 15 µg/L to 10 µg/L beginning that date. Lead sampling at lead service line sites shifts to a paired first-and-fifth-liter protocol; systems must analyze both samples and use the higher value for compliance. TCEQ is implementing the LCRI through its existing LCRR framework. (TCEQ LCRR/LCRI page)

PFAS reporting. Texas systems must complete initial PFAS monitoring by April 26, 2027. Results for PFOA, PFOS, PFHxS, PFNA, and HFPO-DA — plus the Hazard Index for mixtures containing two or more of {PFHxS, PFNA, HFPO-DA, PFBS} — will appear in CCRs covering 2027 data. PFAS MCLs become enforceable April 26, 2029. (89 FR 32532, EPA PFAS NPDWR)

Biannual delivery. Systems serving 10,000 or more begin the twice-yearly schedule: July 1 and December 31, starting with the 2027 compliance year. (40 CFR § 141.155(j)(2))

Mandatory summary section. Every CCR covering 2026 data (due July 1, 2027) must include a summary displayed prominently at the beginning of the report, per 40 CFR § 141.156, effective January 1, 2027. The summary must be written in plain language and may include infographics.

Electronic delivery codified. The 2024 CCR rule revisions formally codified four delivery methods — paper mail, mail notification with link, email with link or electronic version, and primacy-agency-approved alternatives — under 40 CFR § 141.155(a). Paper copy on request remains required for any system using electronic delivery. See Electronic CCR delivery.
