Lead service line inventory

Utility reports no confirmed lead service lines

SALMON CREEK MIDDLE SCHOOL reports 0 confirmed lead service lines, 14 non-lead, 0 unknown (total 14) 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)
  • 14 confirmed non-lead (100.0%)
  • 14 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).

Recorded contaminant measurements (from violations)

When this system exceeded a regulatory limit and EPA recorded the measured value, that value is shown here. These are not routine sample results: they are the values the violation was triggered on.

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.

1 active health-based violation

EPA records 1 health-based violation that has not yet been resolved. An additional 4 health-based violations in the last 5 years are already resolved.

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.
