Questions
Frequently asked questions
Is Bell tap water safe to drink?
PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For Bell, PFOS 15 ng/L was measured above the 4 ng/L federal limit in EPA's 2024 testing. GSWC - BELL, BELL GARDENS (PWSID CA1910011) 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 Bell?
GSWC - BELL, BELL GARDENS (PWS ID CA1910011) is the public water system on record for Bell, California, serving about 55,050 people. Confirm the utility on your water bill before acting on a specific finding.
Where does Bell get its drinking water?
Surface water (primary source of record in EPA SDWIS).
Are PFAS "forever chemicals" in Bell's water?
Yes. In EPA's UCMR 5 testing (2025-01-06 to 2025-10-21), PFOS was measured at 15 ng/L against a 4 ng/L federal limit. PFBS (4.1 ng/L, below the 2,000 ng/L EPA health advisory), PFHxA (6.6 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 (11 ng/L) and PFPeA (7.3 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 Bell's tap water?
Lead is not in Bell'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 Bell water report show?
PurityMap's current record for Bell holds 31 findings: 2 above a reference, 3 detected within the reference, 2 detected with no limit and 24 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.

Methodology: how we analyze water. Prepared with AI assistance and reviewed by the PurityMap Editorial Team before publication.
Something off with your water's smell, color or taste?
Start with the hot-or-cold tap check. Where GSWC reported something related, it's shown below.
- Rotten-egg smell
- Cloudy or milky water
- Chlorine smell
- Brown or yellow water
- Metallic taste
Lead at GSWC: not detected (90th percentile, 2023–2025 monitoring period). Lead has no taste, so a taste neither shows nor rules it out.
