Galvanized lines treated as lead

Lead service lines

1 galvanized requiring replacement

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.

From the utility's published inventory · See details below
Detected (no safe amount)

Lead

0.0006 mg/L

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

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

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

RRA ARROWHEAD LAKE LOTS reports 0 confirmed lead service lines, 1 galvanized requiring replacement, 736 non-lead, 0 unknown (total 737) in the EPA SDWIS service line inventory (2026Q1).

0 confirmed lead service lines
1 galvanized requiring replacement (LCRI treats these as lead)
0 unknown (0.0% of total)
736 confirmed non-lead (99.9%)
737 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	0.0006 mg/L	December 31, 2024	Detected (no safe level) 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.

Fluoride

Per CDC My Water's Fluoride

RRA ARROWHEAD LAKE LOTS 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.

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 1 monitoring or reporting item (paperwork) during the same period.

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 RRA ARROWHEAD LAKE LOTS's CCR:

Search the web for "RRA ARROWHEAD LAKE LOTS 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.
