Contaminant levels in Volusia County groundwater are low, with no harmful substances detected at levels that exceed EPA health standards. Well owners here face no serious water quality concerns from contamination.
The surficial aquifer that supplies water to this county sits close to the land surface and draws water from sand and other loose materials. This shallow position means contaminants from the surface can reach the water more easily, yet the county's water remains clean. The sandy soil and porous rock filter out pollutants naturally, and low industrial activity and sparse development keep harmful substances from building up in the groundwater.
Based on the surficial aquifer type in this area, groundwater here likely contains elevated calcium and magnesium, making the water hard. These minerals dissolve naturally from the sand and rock as water moves underground in central Florida's geology. Hard water is common across wells in Volusia County and neighboring areas that tap the same shallow aquifer system.
Wells in Volusia County have not shown contaminants exceeding EPA health standards in county-level testing. This is good news for your drinking water. However, county wells do show signs of sediment and iron, which can affect water quality in ways you notice every day.
Sediment and iron in well water create visible problems around your home. You may see reddish or brown staining on sinks, toilets, and laundry. Iron can give water a metallic taste and smell. These minerals can also build up inside pipes and reduce water pressure over time.
We recommend testing your well water because every well is different and yours may have higher or lower levels than what is common in the county. A basic test for bacteria and sediment runs about fifty to one hundred dollars. Testing is the only way to know what is actually in your well so you can treat it properly. If sediment or iron is present, a sediment filter or iron removal system can help.

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.
