Groundwater Profile: Glades County
Most groundwater pumped in Glades County comes from the Surficial Aquifer System, with a significant share also from the Intermediate Aquifer System (USGS, 2015 withdrawals). Across 10 sampled wells, the median hardness is 15 gpg, which the USGS classes as very hard. It applies to wells across Glades County, including around Moore Haven, Buckhead Ridge and Port LaBelle.
What shows up in local well samples:
- HardnessLimited local data (fewer than 20 samples): individual well testing recommended.
Calcium and magnesium dissolved from limestone. Leaves scale on fixtures and water heaters and reduces soap lather. Not a health risk.
Water softener sizing - Chloride (salinity)Median chloride 428 mg/L
A salty taste and faster corrosion, often a sign of saltwater intrusion. The EPA aesthetic guideline is 250 mg/L.

Hydrogen sulfide (the rotten-egg smell) was measured in only 0 Glades 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.

Glades 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 Glades County
The Florida Department of Health in Glades 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 Glades 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
- Chloride and sodium, to catch saltwater intrusion
- After any flood, new well work or a change in taste, color or smell

Frequently Asked Questions
How many homes in Glades County use private wells?
The Florida Department of Health’s Florida Water Management Inventory (2018 data) found 29.7% of built parcels in Glades County on private wells, roughly 1,542 properties.
How hard is well water in Glades County?
Groundwater samples from 10 wells in Glades County have a median hardness of 15 grains per gallon (256 mg/L), which the USGS classes as very hard. Limited local data (fewer than 20 samples): individual well testing recommended. The Florida statewide median is 12.4 gpg.
Is iron a problem in Glades County well water?
The median iron level across 10 sampled wells is 0.08 mg/L, below the EPA aesthetic guideline of 0.3 mg/L (limited local data (fewer than 20 samples): individual well testing recommended). 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 Glades County?
Hydrogen sulfide (the rotten-egg smell) was measured in only 0 Glades 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 Glades County?
Most groundwater pumped in Glades County comes from the Surficial Aquifer System, with a significant share also from the Intermediate Aquifer System (USGS, 2015 withdrawals).
Does boiling well water make it safe to drink in Glades 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.
How often should I test my well water in Glades County?
The Florida Department of Health recommends testing private wells for bacteria and nitrate at least once a year, and again after flooding or well repairs. The Florida Department of Health in Glades County can explain how to collect and submit samples.
