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 Cudahy tap water safe to drink?

PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For Cudahy, PFOS 24 ng/L and PFOA 6.5 ng/L were measured above the 4 ng/L federal limit in EPA's 2024 testing. TRACT 180 MUTUAL WATER CO. (PWSID CA1910159) 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 Cudahy?

TRACT 180 MUTUAL WATER CO. (PWS ID CA1910159) is the public water system on record for Cudahy, California, serving about 14,000 people. Confirm the utility on your water bill before acting on a specific finding.

Where does Cudahy get its drinking water?

Groundwater (primary source of record in EPA SDWIS).

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

Yes. In EPA's UCMR 5 testing (2024-03-27 to 2024-09-20), PFOS was measured at 24 ng/L against a 4 ng/L federal limit and PFOA was measured at 6.5 ng/L against a 4 ng/L federal limit. PFHxA (3.1 ng/L, below the 400,000 ng/L state limit) and PFHxS (5.9 ng/L, below the 10 ng/L federal limit) were also detected. Reverse osmosis and filters certified to NSF/ANSI 53 for PFOA/PFOS reduce them at the tap.

Is there lead in Cudahy's tap water?

Lead is not in Cudahy'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 Cudahy water report show?

PurityMap's current record for Cudahy holds 31 findings: 2 above a reference, 2 detected within the reference and 27 not detected. Each finding links to its dated public record; a parameter that was never monitored is shown as pending, not as a pass.
