The short answer

2 results are above EPA’s legal limit. The worst: Lead, above the action level. No health-based violations on file since 2016.

What handles it

What was found

Lead and copper: EPA SDWIS monitoring periods ending 2023 to 2026.

Nitrate, total trihalomethanes (TTHM) and haloacetic acids (HAA5): Minnesota’s yearly summaries per water system, 2023 to 2025, with EPA’s 2012 to 2019 file for earlier years.

Fluoride, arsenic and chromium (total): EPA’s compliance monitoring file, samples taken from Jan. 9, 2012 to Nov. 20, 2019. Newer results are in the utility’s annual water quality report.

Above the legal limit2

Lead

Comes from pipes, often your own

Above the action level

18ppb

90th percentile, 2024 to 2026

In the latest period, 9 in 10 homes sampled were at or below 18 ppb, above EPA’s action level of 15 ppb. The action level drops to 10 ppb on Nov. 1, 2027, and this result is at or above that. EPA’s health goal for lead is zero.

Copper

Above the action level

1.4ppm

90th percentile, 2024 to 2026

In the latest period, 9 in 10 homes sampled were at or below 1.4 ppm, above EPA’s action level of 1.3 ppm.

What handles it

A certification covers specific claims, not a whole standard. Look for these claims on the certifier’s listing, not the box. Wording varies a little: NSF writes “Lead Reduction,” WQA just “Lead.”

  • NSF/ANSI 53

    Claims: Lead Reduction, Copper Reduction

    For: Lead, Copper

  • NSF/ANSI 58

    Claims: Lead Reduction, Copper Reduction

    For: Lead, Copper

At the tap, or for the whole house?

Lead and copper usually come from pipes and fixtures inside or near your home. A whole-house system sits where water enters, so it cannot catch what your own plumbing adds after it. For those, the filter that counts is the one at the tap. How whole-house systems compare.

What this report can’t tell you

  • Everything else. Nitrate, total trihalomethanes (TTHM) and haloacetic acids (HAA5) results here are Minnesota’s own yearly summaries from 2023 on, with EPA’s national file for 2012 to 2019. Fluoride, arsenic and chromium (total) come from EPA’s file alone, which ends in 2019. Springfield’s own annual report, which it must send you every year, has newer results for those and the contaminants this page does not show.

  • Your own plumbing. Lead results are the 90th percentile across homes the utility samples. Your home’s service line, solder and fixtures decide yours. A certified lab test is the only way to know.

  • What it means for your health. This page reports what the records show and EPA’s limits and goals; it is not medical advice. If you are worried about a health effect, talk to a doctor or your local health department.

  • Anything after the latest data. SDWIS data is from 2026 Q3; UCMR 5 didn’t sample this utility; Minnesota’s yearly summaries cover 2023 to 2025; EPA’s compliance samples are from Jan. 9, 2012 to Nov. 20, 2019.

Testing your own tap

Springfield’s results are for the water it sends out. What your own service line, solder and fixtures add shows up only in a test of your tap, by a lab Minnesota certifies.
