Common questions about Bergen County water
Is tap water in Bergen County safe to drink?
1 of the 6 largest systems here have at least one health-based violation in EPA records since October 2021 (see each system below for status). Veolia Water New Jersey Hackensack's most recent lead 90th percentile was 5.8 ppb (2026), below the 15 ppb action level. Public records can't guarantee what comes out of your tap, especially with older plumbing, so a home test is the surest check.
How hard is the water in Bergen County?
There's no published utility figure in our data, but untreated local stream and well samples in Bergen County have a median of about 7.5 grains per gallon (129 mg/L, hard). That's a low-confidence estimate of source water, not your tap, so test before you buy equipment. For a 3-person home at 7.5 gpg, our softener calculator suggests a 24,000 grain unit as a starting point.
Is there PFAS in Bergen County water?
6 of the 6 sampled systems listed here detected at least one PFAS in EPA's UCMR 5 testing, and 12 results were above the level of a federal limit in at least one sample. A detection isn't a violation: federal PFAS limits apply to running annual averages starting in 2029.
