No contaminants have been detected in Sarasota County's groundwater at levels of health concern. Contaminant levels here are low, which is good news for well owners.
The surficial aquifer system in this county sits close to the surface and is naturally protected by sandy soil and sediment that act like a filter. This shallow groundwater system has not accumulated harmful contamination because the local land use and geology work together to keep it clean. The sandy layers above and around the aquifer do a good job of screening out pollutants before they reach the water that supplies your well.
Water from this county's wells draws from sandy and shell-based rock layers that do not typically add strong mineral character. Without detailed mineral data available, the sandy composition of the surficial aquifer suggests water here is likely to be relatively clean and free of the heavy minerals that accumulate in harder rock types. Most wells in this county should deliver water with modest mineral content.

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.
