Your water bill or annual water quality report names your actual supplier.
CITY OF COLLEGE STATION (EPA PWSID TX0210002) delivers groundwater to 104,103 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.
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 tap test can confirm levels at your home before you choose treatment.
PFBS 3.7 ng/L, below the 2000 ng/L EPA health advisory (+3 more PFAS detected)
Lithium 18.6 µg/L, above the 10.0 µg/L EPA health reference level
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 College Station, PFAS were detected below their limits, and PFBA 8.9 ng/L and PFPeA 5.6 ng/L with no federal or state limit. CITY OF COLLEGE STATION (PWSID TX0210002) has a Purity Score of 100/100 (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.
CITY OF COLLEGE STATION (PWS ID TX0210002) is the public water system on record for College Station, Texas, serving about 104,103 people. Confirm the utility on your water bill before acting on a specific finding.
Groundwater (primary source of record in EPA SDWIS).
In EPA's UCMR 5 testing (2023-05-23 to 2023-11-02), PFBS was detected at 3.7 ng/L, below the 2,000 ng/L EPA health advisory and PFHxA was detected at 5.9 ng/L, below the 400,000 ng/L state limit. PFBA (8.9 ng/L) and PFPeA (5.6 ng/L) were also detected; they have no federal or state limit.
Lead is not in College Station'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 College Station holds 31 findings: 1 above a reference, 2 detected within the reference, 2 detected with no limit and 26 not detected. Each finding links to its dated public record; a parameter that was never monitored is shown as pending, not as a pass.
