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

Service line inventory still in progress

ST. MARYS reports 0 confirmed lead service lines, 5,097 non-lead, 3,293 unknown (total 8,390) 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
  • 0 galvanized requiring replacement (LCRI treats these as lead)
  • 3,293 unknown (39.2% of total)
  • 5,097 confirmed non-lead (60.8%)
  • 8,390 total service lines in the system
What to do if your service line might be lead
  1. 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.
  2. 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.
  3. 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.
  4. 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).

PFAS and emerging contaminants

This system was tested 155 times under EPA's latest PFAS monitoring program; 1 of the 30 chemicals tested was 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
lithium
0.009 mg/LJuly 1, 2024 Below regulatory thresholds
Tested but not detected (29 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

ST. MARYS 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 12 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.
