Levy County has one of the highest rates of private well reliance in North Central Florida, with 80.8% of built parcels drawing drinking water from an onsite well rather than a public utility, according to the Florida Department of Health.
Levy County is a Gulf Coast county that includes the historic fishing village of Cedar Key, and like the rest of this region, its groundwater comes from the Floridan Aquifer, a limestone formation that shapes which well water problems show up most often here.

Groundwater Profile: Levy County
Most groundwater pumped in Levy County comes from the Floridan Aquifer (USGS, 2015 withdrawals). Across 178 sampled wells, the median hardness is 13.7 gpg, which the USGS classes as very hard. It applies to wells across Levy County, including around Williston, Chiefland and Inglis.
What shows up in local well samples:
- HardnessMedian 13.7 gpg; 90% of 178 sampled wells above 7 gpg
Calcium and magnesium dissolved from limestone. Leaves scale on fixtures and water heaters and reduces soap lather. Not a health risk.
Water softener sizing
Hydrogen sulfide (the rotten-egg smell) was measured in only 0 Levy County wells, too few to say how common it is. Limited local data (fewer than 20 samples): individual well testing recommended. If you notice the smell, a sulfide test confirms it.

Levy County and Florida: share of sampled wells (all well types, samples since 2000) whose typical value exceeds the level, from the Water Quality Portal. United States: USGS Circular 1332, about 2,100 domestic wells in 48 states sampled 1991 to 2004. Well types and years differ, so read this as a broad comparison. Highlighted cells are well above the national share.

Testing Your Well in Levy County
The Florida Department of Health in Levy County oversees private well permitting in the county and investigates suspected contamination. For routine bacteria, nitrate or full-panel tests, use a laboratory certified by the Florida Department of Health.
What to test for in Levy County:
- Bacteria (total coliform and E. coli) and nitrate, at least once a year (Florida Department of Health recommendation)
- Hardness in grains per gallon (gpg) to size a softener
- After any flood, new well work or a change in taste, color or smell
The Florida Department of Health in Levy County can explain how to collect samples and where to send them. Statewide guidance is on the FDOH private well testing page, and our guide to how to test well water covers which tests to order.

Frequently Asked Questions
How hard is well water in Levy County?
Groundwater samples from 178 wells in Levy County have a median hardness of 13.7 grains per gallon (235 mg/L), which the USGS classes as very hard. About 90% of sampled wells are above 7 gpg, the point where a water softener is usually worthwhile. The Florida statewide median is 12.4 gpg.
Is iron a problem in Levy County well water?
The median iron level across 171 sampled wells is 0.09 mg/L, below the EPA aesthetic guideline of 0.3 mg/L, and 37% of wells exceed it. Most wells will not stain, but if yours does, a lab test tells you whether iron or manganese is the cause.
Why does my well water smell like rotten eggs in Levy County?
Hydrogen sulfide (the rotten-egg smell) was measured in only 0 Levy County wells, too few to say how common it is. Limited local data (fewer than 20 samples): individual well testing recommended. If you notice the smell, a sulfide test confirms it. The smell is a nuisance rather than a health risk at typical levels.
Which aquifer supplies wells in Levy County?
Most groundwater pumped in Levy County comes from the Floridan Aquifer (USGS, 2015 withdrawals).
Does boiling well water make it safe to drink in Levy County?
Only if bacteria are the problem. A one-minute rolling boil kills germs, but it does not remove nitrate, arsenic or other chemicals, and it concentrates them as water evaporates. Test first, and see our boiling well water myth buster for when boiling helps.
Why does Levy County have so many private wells?
Rural counties like Levy often fall outside the service area of any municipal water utility, so new homes are built with an onsite well by default. The Florida Department of Health’s 2022 parcel mapping found 80.8% of built parcels here on private wells.
Do I need to test my well water if my neighbors say theirs is fine?
Yes. Well depth, casing condition, and the exact aquifer layer tapped can vary block to block, so one neighbor’s clean test does not guarantee another’s. A full annual test is the only reliable way to know what is in your own water.
Is Floridan Aquifer water generally safe to drink untreated?
Much of it is chemically safe but aesthetically unpleasant (hard, sulfur-smelling, or iron-stained), which is why treatment here is usually about comfort and plumbing protection rather than an acute health risk. A lab test is still the only way to rule out bacteria, nitrates, or other contaminants specific to your well.
