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.
A federal limit (an MCL or action level) is an enforceable legal cap; a health goal is often stricter. Meeting the limit is a compliance fact, not a health clearance, and PurityMap publishes no overall compliance verdict.
Plumbing inside a home can add lead that the system record can't show. A tap test tells you what reaches your glass.
lead 0.93 µg/L, below the 15 µg/L action level
PFHxS 3.3 ng/L, below the 10 ng/L limit (+1 more PFAS detected)

What it can't tell you: It shows a lead range, not an exact level, and tests nothing else unless you pay extra for the optional lab test.
FREMONT, CITY OF (PWS ID NE3105312) is a public water system serving 27,230 people in Fremont, Nebraska.
FREMONT, CITY OF is on record as drawing from groundwater. The source shapes which contaminants matter most for this system.
PurityMap's record for FREMONT, CITY OF holds 31 findings: 1 above a reference, 3 detected within the reference and 27 not detected, from 31 evidence records. Every finding links to its source; a substance that was never monitored is shown as pending, not as a pass.
PurityMap does not issue a safety verdict. It publishes FREMONT, CITY OF's measured results against each contaminant's benchmark so you can read them in context. Safety depends on the specific finding, your plumbing, and how the water reaches your tap.
The latest published record for FREMONT, CITY OF is dated 2026-10-15. Utilities report on regulatory cycles, so results reflect the monitoring period rather than a live reading.
No. It is assessed at the water-system level from FREMONT, CITY OF's own monitoring. It does not cover the service line to your building or the plumbing inside it, which can add lead and other metals after the water leaves the system. A tap test is the way to know what reaches your glass.
Lithium, Perfluorohexanesulfonic acid (PFHxS), Lead (90th percentile) and Perfluorobutanesulfonic acid (PFBS) were detected in this record. Each finding shows its measured value, its reference and its source on this page.
Start with what the record shows: the PFAS findings above list each measured value against its reference. This record cannot show your home's plumbing, so a tap test tells you what reaches your glass. If you decide to treat your water, look for a filter whose certification covers the specific PFAS compounds in your record; the section "Certified for a concern found here" lists only products with a current certification record for these concerns.
