Short answer: In the 2021–2025 records we hold for Michigan State University, copper (90th percentile) is above its federal limit, and a health-based violation is on record (EPA SDWIS). Also worth knowing: lithium sits above a screening level. 3 substances were detected and 29 were tested and not detected. The water is from Michigan State University, serving 12,793 residents.

MICHIGAN STATE UNIVERSITY (EPA PWSID MI0004340) delivers groundwater to 12,793 residents. This report reflects 29 individual PFAS result(s) from the source UCMR5 observations and the latest Lead & Copper Rule 90th-percentile result. Water hardness and disinfectant type are pending the utility's own annual report.
1health-based violation in the last 10 years
From EPA SDWIS. Counted once per contaminant per year, as in the Track record score.
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.
Every filing is listed; the Track record score counts at most one per contaminant per year.

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.

Lab-certified results
ETR Laboratories
50+ substances, including lead, copper, arsenic, nitrate, hardness and coliform bacteria
What it can't tell you: It does not test PFAS, and not every result on the panel falls under the lab's accredited scope.
Screening: quick check, not lab-grade
Silver Lake Research
Lead, bacteria, nitrate, copper, iron, chlorine, hardness and pH
What it can't tell you: Each test gives a yes/no or a rough range, not a lab number, and it cannot detect PFAS or arsenic.

Ask your utility first
Water utilities keep an inventory of service-line materials. Ask Michigan State University whether your address is on it before you replace pipes.
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. Michigan State University’s record shows lead at 2 µg/L (15 µg/L federal action level). Test first-draw water, then filter if needed.
None of the 29 PFAS tested was detected in Michigan State University’s record. 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.
Your utility’s annual water quality report usually lists hardness; a test strip also measures it.
Reverse osmosis reduces many dissolved contaminants, including lead and minerals, at a single faucet, with some water sent to drain.

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 Michigan State University, no regulated PFAS were detected in EPA's 2024 testing; the lead 90th-percentile result was 2 µg/L against the 15 µg/L action level; one health-based violation is on record (Combined radium-226/228). MICHIGAN STATE UNIVERSITY (PWSID MI0004340) has a Purity Score of 72/100 (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 →

MICHIGAN STATE UNIVERSITY's most recent lead 90th-percentile result (2025) was 2 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. MICHIGAN STATE UNIVERSITY · PWSID MI0004340 · Purity Score 72/100 (Fair) · Confidence: moderate · Assessed at the water-system level
Full methodology →Start with the hot-or-cold tap check. Where Michigan State University reported something related, it's shown below.
Lead at Michigan State University: 2 µg/L (90th percentile, 2025 monitoring period). Lead has no taste, so a taste neither shows nor rules it out.
Copper: 1.51 mg/L (90th percentile, 2021–2023 monitoring period). The federal action level is 1.3 mg/L.
