Short answer: No measured result is above a legal limit. Superior MD No 1 serves 17,900 residents.
Your water bill or annual water quality report names your actual supplier.
SUPERIOR MD NO 1 (EPA PWSID CO0107725) delivers surface water to 17,900 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.
2health-based violations 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 records describe the system. A certified lab test shows what reaches your glass.
Screening tells you if something is worth a closer look; a lab result is the number you can act on.

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.
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.

PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For Superior, no regulated PFAS were detected in EPA's 2024 testing. SUPERIOR MD NO 1 (PWSID CO0107725) has a Purity Score of 98/100 (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.
SUPERIOR MD NO 1 (PWS ID CO0107725) is the public water system on record for Superior, Colorado, serving about 17,900 people. Confirm the utility on your water bill before acting on a specific finding.
Surface water (primary source of record in EPA SDWIS).
None of the 29 PFAS in EPA's UCMR 5 testing (2023-05-31 to 2024-02-08) was detected. "Not detected" means below the lab's reporting limit, not proven zero.
Lead is not in Superior's current published record. Lead usually enters from a building's own pipes and fixtures, so a certified home test is the way to know yours.
PurityMap's current record for Superior holds 31 findings: 31 not detected. Each finding links to its dated public record; a parameter that was never monitored is shown as pending, not as a pass.
