Iron, manganese, and arsenic are present in Osceola County groundwater. Iron and manganese exceed EPA health standards, which is concerning enough to warrant attention.
These metals dissolve naturally from the rock layers beneath the county as groundwater moves slowly through cracks and spaces underground. The "other rocks" composition here--a mix of different stone types--naturally releases these metals into the water over time.
Groundwater in this county is notably high in iron. Iron concentrates in the water because the underlying rock contains iron-bearing minerals that dissolve as water sits in contact with them. This characteristic is common across wells in Osceola County.
Wells in Osceola County commonly contain iron and manganese at levels that exceed EPA health standards. Iron and manganese are metals that dissolve naturally from rock layers as groundwater moves slowly underground. Long-term exposure to elevated manganese can affect your nervous system and brain development. Iron itself is not toxic, but it can accumulate in your body over years of drinking.
Water from wells in this county often has a noticeable metallic taste and orange or brown staining on sinks, toilets, and laundry. Iron can also clog pipes and reduce the lifespan of water heaters and dishwashers over time. You may notice buildup and scaling on fixtures and inside appliances as minerals accumulate.
We recommend testing your well water to see what is actually in it, since every well is different and yours may have higher or lower levels than what is common in the county. Testing is the only way to know what needs treatment. A basic health screen typically costs fifty to one hundred dollars. Iron removal systems or water softeners can help address these mineral concerns.

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.
