Galvanized lines treated as lead

Lead service lines

56 galvanized requiring replacement · 11 unknown

EPA's Lead and Copper Rule Improvements treat galvanized service lines as lead, because galvanized iron pipe installed downstream of an old lead component absorbs and continues to release lead for years after the lead source is removed.

Not fluoridated

Fluoride

Not added

CDC's My Water's Fluoride listing does not report this system as fluoridating its drinking water.

Per CDC My Water's Fluoride · See details below

Past 5 years: 4 health-based violations on file, all marked Resolved or Archived. See compliance history 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

Lead or galvanized-requiring-replacement service lines confirmed in this system

CITY OF MINERAL WELLS reports 0 confirmed lead service lines, 56 galvanized requiring replacement, 7,726 non-lead, 11 unknown (total 7,793) in the EPA SDWIS service line inventory (2026Q1). EPA's Lead and Copper Rule Revisions treat unknown and galvanized-requiring-replacement lines as lead for notification and replacement scheduling until verified.

0 confirmed lead service lines
56 galvanized requiring replacement (LCRI treats these as lead)
11 unknown (0.1% of total)
7,726 confirmed non-lead (99.1%)
7,793 total service lines in the system

Why this is a health concern. A galvanized iron service line that was ever installed downstream of a historic lead component (a lead service line, a lead gooseneck connector, or lead solder) absorbed lead into its corrosion layer over decades. The pipe continues to release that accumulated lead into water for years after the upstream lead source is removed. That is why EPA's LCRI treats GRR lines as lead and requires their replacement on the same 10-year schedule as confirmed lead lines. Read our plain-English lead guide.

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).

Most recent measurements per contaminant (Lead and Copper Rule) . Sorted by risk: concern first, then caution, then unrated, then safe.
Contaminant	Most recent	Date	Risk
Lead PB90	0 mg/L	December 31, 2023	Below regulatory thresholds Lead has no safe level (MCLG=0). LCR action level is 0.015 mg/L for the 90th-percentile sample; the LCRI (Oct 2024) lowers the action level to 0.010 mg/L effective Nov 2027. Caution at any detection above LOD; concern anchored to the future LCRI value (0.010 mg/L) for forward consistency. Learn more about Lead. Source.

PFAS and emerging contaminants

This system was tested 120 times under EPA's latest PFAS monitoring program; 2 of the 30 chemicals tested were detected.

What is this testing program?

EPA's fifth Unregulated Contaminant Monitoring Rule cycle (UCMR 5, 2023 to 2025) required every public water system serving over 3,300 people to test for 29 per- and polyfluoroalkyl substances (PFAS) plus lithium; 30 chemicals in total. Most recent detection per chemical shown below.

Most recent UCMR 5 detection per contaminant . Sorted by risk: concern first, then caution, then unrated, then safe.
Contaminant	Most recent detection	Date	Risk
PFBA	7.3 ng/L	September 10, 2025	No federal limit EPA has not set a federal drinking-water limit for this contaminant. It is among the substances EPA is studying under the Unregulated Contaminant Monitoring Rule (UCMR). See the guide for what the science currently says. Learn more about PFBA.
lithium	0.011 mg/L	September 17, 2025	Below regulatory thresholds HAL only; not enforceable. UCMR-monitored. Learn more about lithium. Source.

Tested but not detected (28 contaminants)

EPA tested for these substances and every sample was below the minimum reporting level. Absence of detection does not mean true zero; it means below the laboratory's quantitation threshold.

Fluoride

Per CDC My Water's Fluoride

CITY OF MINERAL WELLS does not add fluoride to its drinking water.

This system has not reported adding fluoride to its water on CDC's My Water's Fluoride listing. Natural fluoride may still be present at trace levels from the source water; 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.

4 resolved health-based violations in the last 5 years

All 4 health-based violations in the last 5 years are marked Resolved or Archived. Past violations do not represent current water quality.

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 CITY OF MINERAL WELLS's CCR:
