No contaminants have been detected in Martin County's groundwater at levels of concern. Contaminant levels here are low.
Martin County sits on sandy and porous ground that filters water naturally as it moves down. The shallow surficial aquifer in this area does not sit above major sources of pollution, and the sandy layers act like a screen that keeps harmful chemicals out. The flat landscape and groundwater flow patterns also help protect the water from nearby contamination.
Groundwater in this county tends to be elevated in iron and manganese, minerals that seep into water from the sandy and shell-rich rock below. These minerals are common in Florida's surficial aquifer system where water passes through iron-bearing sand and shell deposits. Many wells across this county show detectable iron and manganese, though levels and visibility vary from well to well.
The county well data shows no contaminants exceeding EPA health standards. This is good news for wells in Martin County overall. However, county-level data represents averages across many wells, and your individual well could have different water quality.
Information about minerals like iron and sodium levels in county wells is not available, so we cannot describe what aesthetic issues are common here. Your well may have staining, scale buildup, or taste and odor issues depending on what minerals are present underground near your property.
We recommend testing your well water to find out exactly what is in it. Testing is the only way to know if your well needs treatment. A basic screening for bacteria and nitrate runs fifty to one hundred dollars, while a comprehensive metals and minerals panel costs two hundred to four hundred dollars. Once you know what contaminants are present, you can install appropriate filters or treatment systems to address them.

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.
