Your water bill or annual water quality report names your actual supplier.
SUISUN-SOLANO WATER AUTHORITY (EPA PWSID CA4810005) delivers surface water to 29,105 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.
3health-based violations in the last 10 years
From EPA SDWIS. Counted once per contaminant per year, as in the Track record score. All 11 EPA filings are listed below.
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 Suisun City, no regulated PFAS were detected in EPA's 2024 testing. SUISUN-SOLANO WATER AUTHORITY (PWSID CA4810005) has a Purity Score of 74/100 (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.
SUISUN-SOLANO WATER AUTHORITY (PWS ID CA4810005) is the public water system on record for Suisun City, California, serving about 29,105 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 (2024-01-25 to 2024-10-08) was detected. "Not detected" means below the lab's reporting limit, not proven zero.
Lead is not in Suisun City'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 Suisun City 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.
