Groundwater in Marion County shows no contaminants detected above EPA health standards. Contaminant levels in this county's groundwater are low.
The local rock and soil in Marion County naturally filter and protect groundwater from contamination. The area's geology acts as a natural barrier that keeps harmful substances from reaching the water supply. This clean water reflects both the protective rock layers above the aquifer and the generally low industrial activity in much of the county.
Data on iron, sodium, and sulfate levels in Marion County groundwater is not available, so the mineral character of water from individual wells cannot be fully described. Wells in this area draw from mixed rock types, which means water quality can vary from one property to another. Testing your own well is the best way to know what minerals and characteristics your water contains.
Good news for Marion County well owners. The data shows that wells in this county do not have contaminants exceeding EPA health standards. This means the common water quality issues found in some Florida counties are not showing up as widespread problems here.
Since the county data does not reveal mineral concerns like high iron, hardness, or sodium issues, you may not experience staining, scale buildup, or taste problems in your water. However, this county-level picture does not tell you what is in your specific well.
We recommend testing your well water to find out what you actually have. Every well is different, and your water could have higher or lower levels of minerals and contaminants than what the county data shows. Testing is the only way to know for sure and to decide if any treatment is needed. A basic test costs around fifty to one hundred dollars and checks for bacteria and nitrate, while a more complete minerals panel runs two to four hundred dollars.

MCL = Maximum Contaminant Level (EPA limit for public water; used as benchmark for private wells). Distribution shows % of sampled wells in each concentration band. Methodology.
* Microbial contaminants (E. coli, coliform) reflect only samples from the last 10 years.
