Short answer: In the 2023–2025 records we hold for Springfield, PFOS had a sample above a 2024 EPA limit (not a violation: the limit is judged on a yearly average, due 2029). Also worth knowing: lithium sits above a screening level, and the water is hard. 5 substances were detected and 27 were tested and not detected. The water is from City Utilities of Springfield, serving 210,898 residents.

CITY UTILITIES OF SPRINGFIELD (EPA PWSID MO5010754) delivers surface water to 210,898 residents. This report reflects 29 individual PFAS result(s) from the source UCMR5 observations and the latest Lead & Copper Rule 90th-percentile result. The utility's 2025 CCR reports hard water.
0health-based violations in the last 10 years
From EPA SDWIS. A clean violation history means no enforcement action was recorded; it does not cover contaminants without a limit.
No result is not a pass. Your utility's annual water quality report may list them, and a certified lab test covers your own tap.
The record describes water leaving treatment and samples across the system. Pipes, solder and fixtures inside a building can add lead the record can’t see, especially in older buildings with lead service lines.

Lead service lines
City Utilities of Springfield reported 1 lead and 16 galvanized service lines to replace in EPA’s inventory (2026Q2). Many utilities replace these lines for free or share the cost. Ask City Utilities of Springfield whether your home’s line is on its list before you pay anyone.
Local help
Call to be connected with a local plumbing provider about lead service lines, repiping or fixture replacement.
Older buildings may have lead service lines, solder or fixtures. Springfield’s record shows lead at 5.1 µg/L (15 µg/L federal action level). Test first-draw water, then filter if needed.
2 of 29 PFAS tested were detected in Springfield’s record (PFOS 4.3 ng/L and PFBS 3 ng/L); 1 above its limit. If PFAS matters to you, a filter certification names each compound it covers.
Most utilities keep chlorine or chloramine in the pipes. A carbon filter certified for taste and odor reduces either; your utility can tell you which it uses.
Scale is a comfort and appliance issue, not a health one.
Reverse osmosis reduces many dissolved contaminants, including lead and minerals, at a single faucet, with some water sent to drain.
Get one email when Springfield’s record changes.
One email when a new sampling round is published, a result moves above or below its reference, or the system's score changes.PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For Springfield, PFOS 4.3 ng/L was measured in one EPA sample, above the 4 ng/L limit EPA set in 2024 (not a violation: the limit is judged on a yearly average, due 2029); the lead 90th-percentile result was 5.1 µg/L against the 15 µg/L action level. CITY UTILITIES OF SPRINGFIELD (PWSID MO5010754) has a Purity Score of 71/100 (confidence: moderate), assessed at the water-system level and computed only from contaminants that were measured. Water can change in your own pipes, so a certified test is the only way to know what comes out of your tap. What we found →

Yes. In EPA's UCMR 5 testing (2024-03-26 to 2024-12-12), PFOS was measured at 4.3 ng/L in one EPA sample, above the 4 ng/L limit EPA set in 2024. That limit is judged on a yearly average, and water systems have until 2029 to meet it, so a single sample is not a violation. PFBS (3 ng/L, below the 2,000 ng/L EPA health advisory) was also detected. Reverse osmosis and filters certified to NSF/ANSI 53 for PFOA/PFOS reduce them at the tap. What we found →
CITY UTILITIES OF SPRINGFIELD's most recent lead 90th-percentile result (2023–2025) was 5.1 µg/L, below the 15 µg/L action level. That figure comes from sampled homes; lead usually enters from a building's own pipes and fixtures, so only a test at your tap tells you what you drink. Your household →

Methodology: how we analyze water. Prepared with AI assistance and reviewed by the PurityMap Editorial Team before publication.
EPA SDWIS, EPA UCMR 5 and utility reports, each dated and linked.
Units converted to one basis; a non-detect kept distinct from zero.
Each result tagged by reference type: MCL, action level, screening level or aesthetic.
Every value sits against its own reference, never a blended one.
Measured subjects summarised at the water-system level; an open health-based violation caps the score.
Treatment is matched to what was found; a product is called certified only when its current certification names it.
What the Purity Score means: a summary of this water system’s published record, capped while a health-based violation is open. It is not a test of any tap. CITY UTILITIES OF SPRINGFIELD · PWSID MO5010754 · Purity Score 71/100 (Fair) · Confidence: moderate · Assessed at the water-system level
