Lead service line inventory
Lead or galvanized-requiring-replacement service lines confirmed in this system
ATLANTA reports 1 confirmed lead service line, 0 non-lead, 0 unknown (total 1) in the EPA SDWIS service line inventory (2026Q1).
- 1 confirmed lead service line
- 0 galvanized requiring replacement (LCRI treats these as lead)
- 0 unknown (0.0% of total)
- 0 confirmed non-lead (0.0%)
- 1 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).
| Contaminant | Most recent | Date | Risk |
|---|---|---|---|
| PB90 | 0.0014 mg/L | December 31, 2024 | Caution |

PFAS and emerging contaminants
This system was tested 360 times under EPA's latest PFAS monitoring program; 4 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.
| Contaminant | Most recent detection | Date | Risk |
|---|---|---|---|
| 6.4 ng/L | April 26, 2023 | No federal limit | |
| 3.6 ng/L | January 10, 2024 | No federal limit | |
| 4.2 ng/L | January 10, 2024 | No federal limit | |
| 3.6 ng/L | January 10, 2024 | No federal limit |
Tested but not detected (26 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.
Data from EPA UCMR 5 (Unregulated Contaminant Monitoring Rule) , last refreshed May 24, 2026.
Fluoride
Per CDC My Water's Fluoride
ATLANTA adds fluoride to its drinking water.
CDC classifies a system as fluoridated when it adjusts fluoride to the recommended level, or when it buys water from a system that does. The U.S. Public Health Service recommends 0.7 mg/L for community water fluoridation.

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.
No health-based violations
No health-based violations on file in the last 5 years. EPA recorded 2 monitoring or reporting items (paperwork) during the same period.

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 ATLANTA's CCR:
- Search the web for "ATLANTA 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.
