Detected (no safe amount)

Lead

0.00143 mg/L

Public health experts agree no amount of lead in drinking water is safe. Even low levels can affect children's brain development.

Most recent lead and copper test · See details below
No lead reported

Lead service lines

No lead reported in inventory

This utility's inventory reports no confirmed lead service lines and a low share of unclassified lines.

From the utility's published inventory · See details below
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: 26 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

Utility reports no confirmed lead service lines

CITY OF GRANITE SHOALS reports 0 confirmed lead service lines, 2,565 non-lead, 0 unknown (total 2,565) 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)
2,565 confirmed non-lead (100.0%)
2,565 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).

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	0.00143 mg/L	June 30, 2024	Caution 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	16.7 ng/L	September 6, 2023	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	0.0113 mg/L	September 6, 2023	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 GRANITE SHOALS 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.

26 resolved health-based violations in the last 5 years

All 26 health-based violations in the last 5 years are marked Resolved or Archived. Past violations do not represent current water quality.

Data from EPA SDWIS (violation records) , last refreshed May 24, 2026.

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 GRANITE SHOALS's CCR:

Search the web for "CITY OF GRANITE SHOALS 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.
