Track record

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.

Questions

Frequently asked questions

Is Bellflower tap water safe to drink?

PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For Bellflower, PFOS 17 ng/L was measured above the 4 ng/L federal limit in EPA's 2024 testing. BELLFLOWER - SOMERSET MWC (PWSID CA1910013) has a Purity Score of 57/100 (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.

Who provides tap water in Bellflower?

BELLFLOWER - SOMERSET MWC (PWS ID CA1910013) is the public water system on record for Bellflower, California, serving about 46,300 people. Confirm the utility on your water bill before acting on a specific finding.

Where does Bellflower get its drinking water?

Surface water (primary source of record in EPA SDWIS).

Are PFAS "forever chemicals" in Bellflower's water?

Yes. In EPA's UCMR 5 testing (2023-09-27 to 2024-10-10), PFOS was measured at 17 ng/L against a 4 ng/L federal limit. PFHxS was detected below its limit. Reverse osmosis and filters certified to NSF/ANSI 53 for PFOA/PFOS reduce them at the tap.

Is there lead in Bellflower's tap water?

Lead is not in Bellflower'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.

What does the latest Bellflower water report show?

PurityMap's current record for Bellflower holds 31 findings: 1 above a reference, 1 detected within the reference and 29 not detected. Each finding links to its dated public record; a parameter that was never monitored is shown as pending, not as a pass.

Every value is the published result from the cited public record. A reporting limit is the lowest level the method could reliably quantify; a non-detect is not a guarantee of zero.
