What we found

2 detected results

Lead (90th percentile)Within reference · Action level15 µg/L federal action level3.4µg/L
① · Measured

3.4 µg/L, sampled 2021–2023 monitoring period. EPA SDWIS (Lead & Copper Rule).

② · Compared

15 µg/L federal action level. EPA health goal (MCLG): 0.

③ · Meaning

The 90th-percentile tap result was 3.4 µg/L (below the 15 µg/L action level).

④ · Where it matters

Usually from lead service lines, solder and fixtures inside buildings, after the water leaves treatment.

⑤ · What to do

Test your own tap first. To reduce it: Lead-certified carbon filter, or reverse osmosis (NSF/ANSI 53 (lead)).

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.

Not in this recordDisinfection by-products weren't monitored in this dataset

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.

Your household

Your tap can differ from the city record

The record describes water leaving treatment and samples across the system. Pipes, solder and fixtures inside a building can add lead the record can’t see, especially in older buildings with lead service lines.

Ask your utility first

Find out if your building has a lead service line

Water utilities keep an inventory of service-line materials. Ask City of Bellingham whether your address is on it before you replace pipes.

Local help

Think your plumbing may be adding lead?

Call to be connected with a local plumbing provider about lead service lines, repiping or fixture replacement.

Is this right for my home?

Choose your situation

Your situation
Your path: I live in an older buildingLead from plumbing is the main question

Older buildings may have lead service lines, solder or fixtures. Bellingham’s record shows lead at 3.4 µg/L (15 µg/L federal action level). Test first-draw water, then filter if needed.

Look forLead reduction: NSF/ANSI 53 (lead)
How to test your tap →
Your path: I care about PFASCheck what was tested

None of the 29 PFAS tested was detected in Bellingham’s record. If PFAS matters to you, a filter certification names each compound it covers.

Look forNSF/ANSI 53 or 58, with each compound you care about named on the listing
PFAS in Bellingham →
Your path: My water tastes of chlorineThe disinfectant is not in this record

Most utilities keep chlorine or chloramine in the pipes. A carbon filter certified for taste and odor reduces either; your utility can tell you which it uses.

Look forNSF/ANSI 42 (chlorine taste and odor)

Your path: I have scale or hard waterBellingham water is soft (1.3 gpg)

Scale is a comfort and appliance issue, not a health one.

Look forSoftener: NSF/ANSI 44 (softeners)

Your path: I want the broadest reductionReverse osmosis at one tap

Reverse osmosis reduces many dissolved contaminants, including lead and minerals, at a single faucet, with some water sent to drain.

Is Bellingham tap water safe to drink?

PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For Bellingham, no regulated PFAS were detected in EPA's 2024 testing; the lead 90th-percentile result was 3.4 µg/L against the 15 µg/L action level. BELLINGHAM-WATER DIVISION CITY OF (PWSID WA5305600) has a Purity Score of 96/100 (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. What we found →

Who provides tap water in Bellingham?

BELLINGHAM-WATER DIVISION CITY OF (PWS ID WA5305600) is the public water system on record for Bellingham, Washington, serving about 141,127 people. Confirm the utility on your water bill before acting on a specific finding. Water utility →

Where does Bellingham get its drinking water?

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

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

None of the 29 PFAS in EPA's UCMR 5 testing (2024-02-06 to 2024-11-05) was detected. "Not detected" means below the lab's reporting limit, not proven zero. What we found →

Is there lead in Bellingham's tap water?

BELLINGHAM-WATER DIVISION CITY OF's most recent lead 90th-percentile result (2021–2023) was 3.4 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. Your household →

What does the latest Bellingham water report show?

PurityMap's current record for Bellingham holds 32 findings: 2 detected within the reference and 30 not detected. Each finding links to its dated public record; a parameter that was never monitored is shown as pending, not as a pass. Records →

Methodology: how we analyze water. Prepared with AI assistance and reviewed by the PurityMap Editorial Team before publication.

Methodology

How PurityMap reads Bellingham’s water

  1. 01Source data

    EPA SDWIS, EPA UCMR 5 and utility reports, each dated and linked.

  2. 02Normalize

    Units converted to one basis; a non-detect kept distinct from zero.

  3. 03Classify

    Each result tagged by reference type: MCL, action level, screening level or aesthetic.

  4. 04Compare to the named reference

    Every value sits against its own reference, never a blended one.

  5. 05Score

    Measured subjects summarised at the water-system level; an open health-based violation caps the score.

  6. 06Match treatment

    Treatment is matched to what was found; a product is called certified only when its current certification names it.

What the Purity Score means: a summary of this water system’s published record, capped while a health-based violation is open. It is not a test of any tap. BELLINGHAM-WATER DIVISION CITY OF · PWSID WA5305600 · Purity Score 96/100 (Excellent) · Confidence: moderate · Assessed at the water-system level
