Common questions about Lee County water
Is tap water in Lee 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). Lee County Utilities's most recent lead 90th percentile was 1.1 ppb (2023), 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 Lee County?
There's no published utility figure in our data, but untreated local stream and well samples in Lee County have a median of about 16.8 grains per gallon (288 mg/L, very 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 16.8 gpg, our softener calculator suggests a 24,000 grain unit as a starting point.
Is there PFAS in Lee County water?
2 of the 6 sampled systems listed here detected at least one PFAS in EPA's UCMR 5 testing, and 3 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.
Which water system serves my address in Lee County?
Most homes are served by Lee County Utilities or one of the other systems listed on this page, but service areas don't follow county lines. Your water bill names your provider, and its annual Consumer Confidence Report has the full test results.
