Glades County, FL
These figures come from wells tested in Glades County, FL, not from any one well.
- Iron is common in wells in Glades County, FL (3 of 10 tested wells were over that level), so it's worth testing for.
- Sulfate is common in wells in Glades County, FL (6 of 31 tested wells were over that level), so it's worth testing for.
- Wells in Glades County, FL are typically very hard (69 wells tested).
- Too few wells have been tested in Glades County, FL (9) to say how common manganese is.
- Only a test of your own well tells you about your water.
What to test for
Start with the four this site covers:
- iron (common in wells here)
- sulfate (common in wells here)
- manganese
- hardness
Most well owners also test for these. We point to the source and don't interpret the results.
- arsenic: occurs naturally in groundwater in many regions. USGS: arsenic and drinking water
- nitrate: common near farmland and septic systems. EPA: private drinking water wells
- total coliform bacteria: the standard yearly well check. EPA: private drinking water wells
- lead and copper: from household plumbing, especially when pH is below 6.5. EPA: lead in drinking water
- PFAS: several states run private-well sampling programs. EPA: PFAS
- a certified lab: states certify labs and some run their own private-well programs. Florida's certified-lab list (from your state drinking-water program)
