Groundwater in Osceola County contains iron and manganese at levels that exceed EPA health standards. The presence of arsenic is also detected, though at lower concentrations.
Iron and manganese dissolve naturally from the rock layers beneath the county as groundwater moves slowly through cracks and spaces underground. Arsenic also comes from certain minerals present in these same rock formations. The bedrock composition here naturally produces these metals when water sits in contact with it over time.
Groundwater in this county is very hard, driven by elevated calcium and magnesium that dissolve from the limestone and other rocks below. These minerals concentrate as water moves slowly through the underground layers and accumulate over time. Very hard water is common across wells throughout Osceola County.
Wells in Osceola County commonly contain iron and manganese at levels that exceed EPA health standards. Long-term exposure to elevated iron can cause problems with your organs over time. Manganese exposure over many years can affect your brain and nervous system development. These metals dissolve naturally from rock layers deep underground.
Wells in this county often show moderate to very hard water with significant iron content. You may notice orange or brown staining on sinks, toilets, bathtubs, and laundry. The water may taste metallic or leave a bitter flavor. Over time, iron buildup can clog pipes and shorten the lifespan of water heaters and dishwashers.
We recommend testing your well water to find out what is actually in it. Every well is different, and your water may have higher or lower levels than what is common in the county. Testing is the only way to know what needs treatment. A comprehensive metals and minerals panel typically costs $200-400 and can identify iron removal systems or water softeners as treatment options.

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.
