Groundwater testing in Polk County shows no contaminants detected above health standards. Contaminant levels here are low.
The shallow aquifer that supplies Polk County wells sits in sandy and other sediment layers that naturally filter water well. The area's land use is mostly rural and agricultural, which keeps industrial and urban sources of pollution away from most wells. Sand is a good natural filter that stops many harmful substances from reaching the water below.
Groundwater in this county is characterized by low mineral content, with minimal iron and other dissolved minerals common in Florida. The sandy aquifer materials do not dissolve easily, so minerals stay low as water moves through them. Most wells in Polk County have soft, clean water without the heavy mineral loads seen in areas with limestone or other rock types closer to the surface.
Good news for Polk County well owners: county water data shows no contaminants detected at levels that exceed EPA health standards. This is an encouraging sign for the wells tested in your area. You can feel confident that the common contaminants that harm health are not showing up in county wells at dangerous levels.
The water quality data for your county does not indicate widespread mineral or aesthetic problems from iron, sodium, or sulfate at this time. This means you are unlikely to see the staining, scaling, or taste issues that come from high mineral content. Your well water should feel and taste relatively normal compared to areas with more mineral buildup.
We recommend getting your own well tested, since every well is different and your water could have higher or lower levels than what is typical in the county. Testing is the only way to know exactly what is in your well so you can treat it properly if needed. A basic test for bacteria and nitrate costs between fifty and one hundred dollars and is a smart first step for any well owner. If testing shows any concerns, your water professional can recommend filtration or other 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.
