Screening tells you if something is worth a closer look; a lab result is the number you can act on.

Questions

Frequently asked questions

Is Placentia tap water safe to drink?

PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For Placentia, PFOS 6.5 ng/L and PFOA 6 ng/L were measured above the 4 ng/L federal limit in EPA's 2024 testing; the lead 90th-percentile result was 2.5 µg/L against the 15 µg/L action level. GOLDEN STATE WC - PLACENTIA/YORBA LINDA (PWSID CA3010035) has a Purity Score of 62/100 (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 Placentia?

GOLDEN STATE WC - PLACENTIA/YORBA LINDA (PWS ID CA3010035) is the public water system on record for Placentia, California, serving about 50,804 people. Confirm the utility on your water bill before acting on a specific finding.

Where does Placentia get its drinking water?

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

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

Yes. In EPA's UCMR 5 testing (2023-03-29 to 2025-01-27), PFOS was measured at 6.5 ng/L against a 4 ng/L federal limit and PFOA was measured at 6 ng/L against a 4 ng/L federal limit. PFBS (5.6 ng/L, below the 2,000 ng/L EPA health advisory), PFHxA (7.7 ng/L, below the 400,000 ng/L state limit) and PFHxS (3.6 ng/L, below the 10 ng/L federal limit) were also detected. PFBA (6.7 ng/L) and PFPeA (10.9 ng/L) were also detected; they have no federal or state limit. Reverse osmosis and filters certified to NSF/ANSI 53 for PFOA/PFOS reduce them at the tap.

Is there lead in Placentia's tap water?

GOLDEN STATE WC - PLACENTIA/YORBA LINDA's most recent lead 90th-percentile result (2023–2025) was 2.5 µg/L, below the 15 µg/L action level. That figure comes from sampled homes; lead usually enters from a building's own pipes and fixtures, so only a test at your tap tells you what you drink.

What does the latest Placentia water report show?

PurityMap's current record for Placentia holds 31 findings: 3 above a reference, 4 detected within the reference, 2 detected with no limit and 22 not detected. Each finding links to its dated public record; a parameter that was never monitored is shown as pending, not as a pass.
