Lead service line inventory

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

CITY OF PORT ARTHUR reports 22 confirmed lead service lines, 111 galvanized requiring replacement, 4,579 non-lead, 14,271 unknown (total 18,983) 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.

  • 22 confirmed lead service lines
  • 111 galvanized requiring replacement (LCRI treats these as lead)
  • 14,271 unknown (75.2% of total)
  • 4,579 confirmed non-lead (24.1%)
  • 18,983 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
  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 90 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.

5.5 ng/LApril 30, 2024 No federal limit
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

CITY OF PORT ARTHUR 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.

9 resolved health-based violations in the last 5 years

All 9 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.
